Most Android and Arduino devices cannot talk to each other when straight “out of the box” – add on hardware and/or system software modifications are required.

You have a variety of choices

0) Bluetooth is fairly clean and now in the $20 range, so it’s both one of the most cost effective choices and one of the least likely to risk damaging the phone hardware – but you said you don’t want that.

1) Some phones such as the G1 have low-voltage serial ports which can be enabled by [rooting and] installing a customized kernel. You will need level translation circuitry as the output voltage of the arduino while low is still too high for the phone to handle. You will also need to source a special HTCUSB connector, either by modifying the full headset adapter or getting it from someplace like sparkfun.

2) Some phones can function as usb hosts by [rooting and] installing a customized kernel. They do not supply usb bus power, but with an arduino you have everything out in the open so cabling up a separate supply should be fairly simple. A few recent tablets have usb host mode out of the box. Edit: with later Android versions, a non-root USB host API and USB bus power may be available, but this varies by model and has been inconsistent.

3) You can use a USB host shield on the arduino, and if the device runs Android 2.3.4 or later use Gooogle’s official ADK protocol to talk to software on the android device; if the android version is earlier, there are unofficial projects which talk the ADB protocol and should work with most devices (perhaps with small modifications). Both are designed to remain within unprivileged userspace on the android device – no rooting, no kernel modifications.

4) You could build a low-baud-rate modem and talk to the android device through its headset jack, using a software modem on the android side.

5) You could put a wireless ethernet shield on the arduino

Smartphones have become an integral part of people’s lives across the globe. The number of users has already reached 3 billion. The United States, China, and India solely count about 1.46 billion smartphone owners. Many of them use Android-operated devices.

For instance, the number of Android smartphone users in the U.S. reached 120.5 million in 2018. This amount is predicted to reach more than 130 million in 2021.

The secret of Android’s popularity lies in the cost of the devices that run the OS. You can find a full-packed Android phone for much cheaper than its Apple competitor. Android devices are offered at a wide range of prices. So, users with different income levels can find a device that suits their needs.

However, Android OS also involves a number of problems. Some people resolve them by rooting their devices. If you want to know more about Android rooting, its advantages, and drawbacks, keep reading this article.

What Is Rooting a Phone?

How to use your android phone as a modem; no rooting required

If you’re bothered by the question “What does rooting a device mean?” here is a simple definition.

Rooting is a process of getting access to privileged control over your device’s Android subsystems. It is also called root access. Smartphone users often perform rooting to bypass limitations set by hardware manufacturers or enhance their devices’ technical characteristics.

As rooting gives you full admin access to your device, you can alter the system in any way you need, remove built-in applications, and change settings.

How to use your android phone as a modem; no rooting required

What Does Rooting a Phone Do?

Rooting allows you to do things that you can’t normally do. After you follow a simple procedure, you’ll get a rooted phone, meaning the one with increased performance, enhanced memory capacity, and other benefits.

Rooting provides infinite customizability. This means that you can customize anything — keyboards, notification menu, camera, etc.

Here’s what you can do after rooting your Android phone correctly:

  • Install rooted apps. If you go to Google Play, you’ll find that rooting is extensive and supported there. Many custom-made applications require rooting. In exchange, they provide you with diverse possibilities in terms of your phone’s system performance enhancement.
  • Install fresh updates. If you have a rooted phone, you don’t need to wait to receive the official updates. You can install any update that you need right now and increase your phone’s performance immediately.
  • Use custom kernels. Do you want to boost your phone’s performance and twofold its battery life? Install a custom kernel on it. Just make sure to do your research and install the correct one.
  • Get tethering for free. Some phone users in the U.S. have to pay extra for USB tethering. Rooting allows you to avoid the fee.
  • Get rid of bloatware. Android phones come overloaded with all kinds of apps that you will never use. They occupy up to half of your phone’s memory, and you can’t delete them. Rooting makes it possible to eliminate all those useless apps, free memory space, and make the interface look cleaner.
  • Get a powerful back-up system. Back-up apps are the most common ones that require rooting. And there is a good reason for that. The standard Android back-up system allows backing up contacts, messages, and media files. A custom app makes it possible to back up anything.
  • Install or move apps to your SD-card. If your phone has low memory capacity, rooting can come to the rescue. After rooting your Android phone, you can easily install new apps on your SD-card or move old ones there.

Does Rooting Involve Any Dangers?

How to use your android phone as a modem; no rooting required

Although there are many reasons why rooting is an excellent option for your phone, the process has drawbacks, too. Before starting to root your device, we recommend that you take into account all the associated risks.

If you are new to rooting, make sure to do research. You need to be extremely careful as installing the wrong file can cause your OS to crash.

Another fact to consider is that Google doesn’t support rooting, although you can find many rooted apps on Google Play. Some manufacturers make it difficult to unlock a bootloader. So, inexperienced users might not want to mess with the system.

Finally, the most significant reason why people choose not to root their phones is insurance. They believe that rooting will void their warranty. Don’t be surprised if your manufacturer refuses to provide services to you after revealing the rooting traces.

Can I Use mSpy Without Rooting My Phone?

Although some apps require your smartphone to be rooted, you don’t necessarily need to do it to use mSpy. If you need spyware for mobile without rooting, mSpy can be a good option for you.

As mSpy comes in two options, Basic and Premium, you can choose the one without rooting. In this case, you can start monitoring someone else’s Android phone right after purchasing a subscription. All basic monitoring possibilities will be available to you.

However, if you want to use mSpy’s advanced features, such as keylogger, social media monitoring, and geofencing, you need to root your device. But no worries — our experienced support managers will help you.

If you keep asking yourself, “Is my phone rooted? What does that mean?”, simply purchase mAssistance and get instructions on rooting your device immediately.

Final Words

Although rooting has a few drawbacks, it can be beneficial for your Android device. A rooted phone can have the latest features installed on it. Rooting can extend your phone’s life and save you from the necessity to spend money on a new smartphone model.

It’s up to you whether to root your phone or not. Just make sure to evaluate all pros and cons beforehand.

Many Android smartphones and tablets offer the ability to set up a Wi-Fi hotspot so that other devices can use your phone’s internet connection. This guide shows how to enable and use this feature on a Samsung smartphone and a Google Pixel as examples; the instructions should apply to most current Android phones and software versions.

On Your Samsung Smartphone

To turn on the Wi-Fi hotspot, follow these steps:

Go to Settings > Wireless & networks. On a Samsung phone, tap Connections > Mobile Hotspot and Tethering.

Turn on the Mobile Hotspot toggle switch. The phone becomes a wireless access point and displays a message in the notification bar when it’s activated.

How to use your android phone as a modem; no rooting required

To find the password and instructions for the hotspot, tap Mobile Hotspot. Use this password to connect your other devices to the hotspot, just as you would connect them to any other Wi-Fi network..

To change the default password, tap Password and enter a new password.

Be selective about with whom you share your Wi-Fi hotspot. Also, bear in mind that data processed through this Wi-Fi feature counts against your monthly allotment of mobile data.

On Your Pixel or Stock Android Smartphone

Follow these steps to enable a hotspot on a Pixel or stock Android:

Go to Settings > Network & Internet.

Tap Hotspot & tethering > Wi-Fi hotspot.

How to use your android phone as a modem; no rooting required

Turn on the Wi-Fi hotspot toggle switch.

How to use your android phone as a modem; no rooting required

Optionally, change the hotspot name, password, and other advanced settings such as automatic shutoff and the AP Band.

Find and Connect to the New Wi-Fi Hotspot

When the hotspot is activated, connect your other devices to it as you would any other Wi-Fi network:

On your device, find the Wi-Fi hotspot. It might notify you that new wireless networks are available.

To find the wireless networks, use your Android phone and go to Settings > Wireless & networks > Wi-Fi settings. Then, follow the general Wi-Fi connection instructions for most computers.

Establish the connection by entering the password for the Wi-Fi hotspot.

Enable Wi-Fi Hotspot for Free on Carrier-Restricted Plans

You might not get internet access on your laptop or tablet after you connect because some wireless carriers restrict Wi-Fi hotspot access only to those who pay for the feature.

In this case, try using an app such as Elixir 2, which toggles the Wi-Fi hotspot on or off on your home screen. This makes it possible to access the hotspot feature directly and without adding extra charges from your wireless provider. If Elixir 2 doesn’t work, FoxFi does the same thing.

Be aware that, in many cases, bypassing carrier limitations constitutes a terms-of-service violation in your contract. Use these apps at your discretion.

Tips and Considerations

When using the Wi-Fi hotspot, follow these recommendations:

Just yesterday I accidentally deleted one very important family photograph from my Samsung. I am suffering from the pain of my stupidity and need to know if there is any way to get back that photo without rooting my phone. I have not installed in any backup app like Dumpster or alike.” – Albert

How to use your android phone as a modem; no rooting required

In daily life, some of you may have such problems that you accidentally delete photos, videos, messages or other files. The panic is not that you cannot retrieve deleted texts messages, or recover deleted photos from Android, but you have to root your Android phone for recovering deleted files with the help of some Android recovery apps. As you are told that, rooting Android is easy, but your phone will suffer more risks of being attacked and surely you will not enjoy the free warranty in the limited time.Here comes the question, how to recover deleted files Android unrooted? Two effective ways are provided to recover Android deleted files without rooting.

Part 1. Recover deleted files Android unrooted with Google backup

Google is a useful backup tool for Android, also does a good job in restoring Android backup. Google Drive provides you the free 15 GB storage for backing up Android files. Once you accidentally delete or lose those files, you could recover the deleted Android files from Google drive, without rooting your Android phone. Before you recover deleted Android contacts, text messages, photos, etc., you had better make sure you have backed up your Android data with “Auto Backup” and “Music Manager” to Google Drive with your Google account.

Back up Android data to Google

Google Drive can back up contacts to Google using your Google account. You could sync photos and video through “Google Photos” to Drive, upload music from “Music Manager” to Drive, and upload other files with “Auto Backup” to drive.

Restore Android data from Google account

Log in your Google Drive on the web, navigate “Trash” to find the deleted files > Click “Restore” to retrieve them to your Google Drive. For recovering your deleted files from Android on Google Drive, there are two situations for your reference.

Situation one : If you have another one Android phone, then you could add your Google account on that phone, and restore all your backup files from Google Drive. Those backup files include, contacts, photos, videos, settings, calendars, etc.

Situation two : If you only want to restore your deleted files on your original Android phone, then you need to log off your Google account, and then add this Google account again. When you add the Google account, you are asked if you are willing to sync Google Drive data to your Android, and you will definitely say yes.

For recovering your deleted Android music, you should follow the above two situations to make it from “Music Manager”. In this way, you could recover your deleted files without rooting your Android phone, but you will only recover part files, like messages.

Part 2. Recover deleted files on Android unrooted via Android Recovery

With the first method, you can handily recover deleted Android files without rooting. But you should know that, the method above doesn’t allows you to retrieve deleted Android messages. To recover deleted files Android unrooted, you can rely on the Android recovery app, FoneLab for Android. It can recover your deleted messages and contacts without rooting. The steps are as following:

1 Free download this program on your computer, install and launch it. Select “Broken Android Phone Data Extraction” and then click on “Start” button.

How to use your android phone as a modem; no rooting required

2 Plug your Android phone to PC with USB cable. Select your Android device information and then click “Confirm” button to make sure the deleted Android files can be recovered.

3 You need to put your Android into download mode to fix your phone first. Follow the introductions to fix your phone condition.

4 After scanning, you could click it to preview the details. Then choose those you want to recover, click “Recover” to get back the deleted Android files to your PC.

How to use your android phone as a modem; no rooting required

Kindly note that this way of recovering deleted files from Android without rooting is not 100% guaranteed. Sometimes, your Android phone may fail to scan some data. So for recovering all your Android data, you are advised to root your Android phone.

I know I’m asking for the close-to-impossible — as a real full-backup certainly requires root permissions. But still there are many folks around not wanting to root their devices — afraid of voiding their warranties or bricking their devices, or just not having their devices supported by any rooting method.

I also know there were a lot of questions asked already on this topic, and I checked all of them having the backup tag — none covers the entire topic, all just have pieces, and especially people new to Android (but other non-power-users as well) would have a hard time figuring out the best way.

So I want a detailed canonical answer to the question:

Not involving root-solutions, how to achieve a backup as close as possible to a full backup?

Please do not give simple one-liner answers like “Use app xyz [full-stop].” If mentioning an app (and I doubt a single app would be the answer here), include what parts are covered by it — as well as ideas on how to fill the gaps it leaves. (And to make it absolutely clear: I know the first thing coming to mind is Titanium Backup — I use it myself, but this does not apply here: This question is strictly about methods for non-rooted devices!) Moreover, the answer should be as generic as possible in terms of applying to a wide range of devices (i.e. it should not be restricted to one device or manufacturer).

I already mentioned having investigated all questions here tagged backup. These will certainly be helpful providing details for answers here, so I will list up the topmost ones concerning my question:

All these provide some details for my question (so feel free to get inspired by them) — but I feel there are still details missing. Also it would be helpful to have a summary — say, an answer including the full description of “the maximum possible”.

A last criterium: While I’d consider cloud-based solutions legit, I’d favour local solutions. If you can provide both: all the better. But some people value privacy quite high (I’m one of them), and thus would not trust their data to some cloud service.

Thanks to Ryan, we now have a solution for a really complete backup of all apps and their data — which I didn’t dare to hope for! The only disadvantage: His solution only works for less than 10% of all Android users; namely those whose devices are running at least with Android 4.x.

So again, I ask the close-to-impossible: Any solutions applicable at least on Gingerbread (2.3.x) or, better, even Froyo (2.2.x) — so they cover the majority of current devices? These solutions may involve multiple tools (try to keep it as simple as possible though; think of your mother to follow your instructions 😉

And keep in mind: NO ROOT!

To further motivate high-quality answers (and hopefully avoid low-quality ones), I will be a harsh one here: As I rarely do, I will down-vote answers not fitting the mentioned criteria on one end — but on the other end, I will setup a bounty for the best answer (which cannot be done immediately, but earliest after 2 days).

Attaching a Second display to your existing Computer setup can be a huge productivity boost but before you hit the buy button on Amazon, ask yourself do you need a dedicated Monitor all the time? If your answer is some times, then I have the perfect solution for you.

If you own an iPad, you must have heard Duet Display– a popular second monitor app for iPad. Thankfully, Android has them too. We tested almost every second monitor app for Android on the Google Play store, and here are our top picks. Let’s begin.

Use Your Android as a Second Monitor

Android smartphones and tablets are pretty versatile in terms of features, you can mirror your Android to another Android and as well as a computer. In general, you need need to install a second monitor app on your Android and install the app’s client app on your computer. Once done you can connect your Android to your computer, using a USB cable or WiFi (when both the devices are connected to the same network) and that’s it.

1. Spacedesk

Spacedesk is a popular choice to transform your Android into a second display monitor for Windows PC. You can connect your PC and Android via USB, Wi-Fi or LAN. The resolution is decent and you get touch support.

To get started, you need to install the necessary drivers on your Windows PC. If you need further help, here is a link to the documentation. The app is available for Windows 7 and above. Opening the app will automatically detect and display all PCs on the same server that has the drivers installed. Simply tap to connect. Launch the app on your Android and connect to your PC. The app should detect the IP address and name of your system.

To use your tablet or Android as an extended display, you just have to configure secondary display options in Windows. To do that go to the Control Panel and then Display Settings. Select Extend These Displays and click OK. You should now be able to use your Android as an extended display.

Spacedesk works well if you don’t want your phone to be bounded by a USB. But that’s the only complaint I have. Since it works wirelessly, there is a noticeable amount of lag. It’s good that you can switch to hotspot and USB.

Supported Medium: LAN, Wi-Fi, USB

2. Splashtop Wired XDisplay

Splashtop Wired XDisplay, as the name suggests, will require you to have a USB handy. Unlike Spacedesk, WiredXDisplay allows you to connect your phone only via USB. On the plus side, since you are connected by a wired medium, you get better resolution and frame rate. It supports Full HD resolution at 60 frames per second.

Wired XDisplay can be installed on both Mac and PC, giving it an edge over Air Display. Mobile apps are available for both Android and iOS. Splashtop uses USB over WiFi for one simple reason – it offers a more responsive and real-time experience. There is no lag whatsoever and you get a battery saver mode which drops the frame rate and resolution to save up on processing.

Supported Medium: USB

3. Google Remote Desktop

Like Remote Desktop for Windows, it also allows you to control your PC via your Android device. You can run commands on your PC from your Android phone. Basically, everything that you can do on your desktop can be done from the Android phone as well. Remote Desktop, like all Google products, is easy to use and simple to set up. You just need to have a working Gmail account. The ability to control your PC remotely is where it shines the most though.

Google Remote Desktop works seamlessly but you cannot use separate apps on both the screen. It doesn’t let you use your phone as an extended display.

Supported Medium: Internet

4. iDisplay

iDisplay is another display mirroring app on this list. iDisplay started with the macOS and iOS but quickly expanded to other Operating systems. You have apps for Windows and Android which makes it a good cross-platform solution. It supports 60 fps and plus offers multi-touch on the device you are using it on.

iDisplay has everything that the other app offers, with one caveat; USB support is not available for Android yet. It does support WiFi though and comes with multi-touch support.

Supported Medium: LAN, Wi-Fi, USB (except Android)

5. Air Display 2

Air Display 2 works the same way for Mac the way Spacedesk does for Windows PC but it comes with a price of 14.99$. It turns your Android device into a secondary screen for your Macbooks. You can extend mirroring the screen to up to 4 secondary devices. On top of that, it also supports full HD displays.

It supports all the way back to Mac OS X 10.8 or Lion. You can also use your PC as a secondary screen for your Mac. But it doesn’t work the other way round like you cannot use Mac or any mobile device as a secondary screen for Windows. I read the FAQs section and it says they are working on a solution, but it also says that they are not “close enough” to provide an ETA.

On the plus side, it offers a more responsive experience thanks to the dynamic compression algorithm the team is using. It also supports retina display, something that is missing in Spacedesk. App also features Air Stylus which you can actually use the secondary device to draw designs on directly.

Air Display works seamlessly but the issue is the pricing model. With every major upgrade Avatron Software i.e. the creator of Air Display increases the price. This is something that bothers long-time users like me but hey if money is not a problem then you are good to go. Another thing that bugs me is that you need to install Air Display Host on your iPhones, Androids, and PCs which you want to use as a secondary screen. But, Air Display can only be installed on Macs. So the cross-platform compatibility gets a little limited.

Duet Display is a popular iOS app that allows you to mirror and extend your Mac’s display to your iPad or iPhone. And now that Apple is providing this feature natively via Sidecar, Duet Display is expanding its horizons with support for Android smartphones and tablets.

Duet Display invited us to beta test their new app, and it worked fine on my Google Pixel and Windows 10. Although, I did encounter a few bugs such as connection breaks. Also, while you can connect your Android Smartphone wirelessly to a Windows computer, you still need to attach a USB cable if you want to use the Android app with macOS.

The app is competitively priced at $9.99 and offers a lot of features and supports a wide range of devices. You can get the app for both Android and iOS devices.
