Basic Android Troubleshooting

We all need to know a little about Basic Android Troubleshooting. If any engineer/programmer came up with a perfect phone, who could put a price on that? It’s somewhat like finding the fountain of youth, or anything perfect in this world. It simply doesn’t exist. We and the phones we make are imperfect—subject to the laws of entropy that dictate a gradual decline into disorder.

Thankfully, we humans can problem solve. But not all problems are intuitive. There are some common solutions to try, however, and certain information that you can collect that will greatly assist you in finding the answers. This is a guide to help you discover solutions and implement them as simply as possible.

Disclaimer: This guide is about promoting different fixes for common problems with Android devices, but it cannot guarantee that each type of fix will work with any phone. Therefore, it’s best to read carefully and see which ones apply to your device.

Problem 1 – How to Improve Device Connectivity

It gets lonely when your phone is out on an island by itself, unable to communicate with Bluetooth, Wi-fi, or any network. And in our connection-driven society, it can cause big problems. Here are some basic fixes that can help you get out of your problem.

  1. Toggle Airplane Mode

    Enable, then disable Airplane Mode.

  2. Add Connection Again

    Set up your Wi-Fi or Bluetooth connection again.

  3. Restart Feature or Device

  4. Scrutinize Settings

    LTE/GSM is usually on by default, but turning it off may help boost your signal in some cases.

  5. Update

    Ensure you have the latest update for your phone. This largely depends on your carrier.

  6. Come Closer to the Source

    If the signal indicator affirms a weak connection, it could be due to other items blocking it or to distance. For example, if you are next to a tall building or in a basement, you might need to relocate.

    Also, you could be too far away from the service tower. Move your device closer to the router. It’s possible for other devices can also create interference, so move any other appliances away.

Problem 2 – How to Improve Battery Life

This is something practically every Android user runs into at least once in a while. Hopefully, you are somewhere you can load up on more juice, but this problem doesn’t only occur when it would be most convenient. That’s why a discussion on how to save battery life is a must when it comes to the basics of troubleshooting Android phones.

There are many reasons why a battery drain can occur. But it is good to detect it in time and figure a way to solve the problem before it is too late.

Problem 3 – How to Fix Issues with Android Apps

Common problems with Android apps include crashing, freezing, or malfunctioning. Some apps can also cause conflicts with each other.

  1. Reboot Device

    This advice is used so much it’s the punchline of a joke, but it does work.

    Reboot Your Device

    Reboot Your Device

  2. Update the Apps

    Make sure you download the latest version of any app and keep it updated.

  3. Use Force Stop & Restart

    If your app is frozen, go to Settings > Apps, select the app, and tap Force Stop. Even if it isn’t frozen, “rebooting” your app can be just as useful as rebooting your phone.

  4. Sign Out & Back In

    Logging out and back in can help the app refresh data.

    sign out

  5. Narrow it Down

    To determine which app it could be (or if this is the problem at all) try going into Safe Mode. Safe Mode only uses those apps that come with your phone without loading any of the third-party software that could be causing the issue. The method by which you enter, Safe Mode can vary by device.

    If you do not experience the same problem in Safe Mode, try uninstalling any third-party app, one-at-a-time, that you think might be the culprit. If the phone still misbehaves in Safe Mode, your problem could be related to the hardware or a corrupted OS, which can be tougher to fix on your own.

  6. Clear App Data &/or Cache

    If the problem seems to be with one application and that application alone, try clearing the cache and app data of that app first. From Apps, go to Settings, then Apps again. From the All tab, select the app. Choose Clear Data or Clear Cache.

  7. Check App Settings

    Make sure that the problem you are experiencing can’t be solved with a simple change in settings. Explore your app’s settings just be certain.

Problem 4 – How to Fix a Slow Interface and Memory Problems

Even though memory problems tend to impact older Android more frequently, you could also find yourself dealing with this issue if you are a heavy user or simply like to store a lot of media directly on your phone.

If you have a ton of apps or photos, you can run into this on newer phones too. No guide on troubleshooting the basics of Android phones would be complete without addressing slowness or performance issues.

  1. Outsource Your Storage

    Store your photos on someone else’s server (in the Cloud) or on the SD card if you can. Services like Dropbox or Google Drive can assist. You can automatically backup to Google Photos by going to Settings > Backup & Sync; you can visit Accounts and enable Auto Sync.

  2. Delete What You Don’t Use

    Not only do photos and apps occupy digital space, but consider your music and videos also.

  3. Backup & Restore

    There are apps that will help you—one of the best is Titanium Backup – Free, but your phone must be rooted.

    If your phone is not rooted, you should try Helium – App Sync and Backup – Free.

  4. Close Apps

    Ensure you are closing your apps when you are done with them; not just returning to the Home Screen while the app is still open and running in the background.

  5. Reduce Animation Transitions

    This won’t help your memory, but it can make your phone seem faster. Obtain developer status by visiting Settings > About Phone and tap on Build Number approximately seven times. Go back to Settings and a new choice should appear—Developer Options.

    Tap on it, scroll down and reduce the Window Transition Animation Scale and Animator Duration to .05x. You can remove the settings altogether, but movement on your phone may not seem to flow as well, and your user experience may suffer.

  6. Soft Reset

    Most of the time a soft reset will cause your phone to snap out of its stupor. Long-press the Power key for approximately 10-15 seconds.

    power off

  7. Clear Cache

    You can start out by clearing the cache for any individual apps that are giving you problems. Go to your App Manager, select the app, and tap the Clear Cache option. If this doesn’t suffice, you can wipe the entire system’s cache partition.

  8. Hard Reset

    If that doesn’t cut it, consider performing a hard reset. This wipes data so you might want to backup what you wish to save!

Problem 5 – How to Improve Network Signal

If you have trouble texting, calling, or otherwise using your phone for tasks even a dumb phone can handle, look no further. If you need help with a specific phone, check out some of our other articles.

  1. Relocate if Needed

    If you don’t have an adequate signal (2-3 bars), try a different area.

  2. Check Data Plan Settings

    Certain carrier plans can implement limits or restrictions on who or how much you can text if it was set up that way.

  3. Resend, Try Again or Restart

    For a bad connection, try calling the other person back. Send your text again. Or reboot your phone.

    Try Calling Again

  4. Check Number

    Try using the full 11-digit phone number, including the prefix 1 and area code.

  5. Clean Your Speaker

    Use compressed air to remove anything from the speaker that doesn’t belong.

  6. Turn on Mobile Data

    Picture and video files can get quite hefty to send, and often require the use of mobile data.

Problem 6 – How to Fix a Phone that Won’t Power On or is Frozen

A soft reset usually solves a host of issues, but what to do when you can’t even do that? Additionally, removing the battery can be very helpful, but what if you don’t have a removable battery? We will take you through some basics of troubleshooting unresponsive Android phones.

  1. Try Safe Mode

    To determine which app, it could be (or if this is the problem at all) try going into Safe Mode. Safe Mode only uses those apps that come with your phone without loading any of the third-party software that could be causing the issue.

    The method by which you enter, Safe Mode can vary by device. If you do not experience the same problem in Safe Mode, try uninstalling any third-party app, one-at-a-time, that you think might be the culprit. If the phone still misbehaves in Safe Mode, your problem could be related to the hardware or a corrupted OS, which can be tougher to fix on your own.

  2. Charge Battery

    If you see the empty battery symbol when you try to turn the device on, it’s time for a charge.


    Make sure your battery is charged

  3. Perform a Factory Reset

    It’s easiest to do this from the Settings menu, but if you can’t access that you will have to use Recovery Mode instead. This wipes your phone like it just came out of the box. If you want to know more about the factory reset, we recommend you read our article “How to Factory Reset and Start Over”.

    Make sure to back-up your data before

  4. Restore Firmware

    This entails connecting your phone to your computer using the proper drivers, going into Download Mode, and flashing the stock firmware for your specific make and model. For Samsungs, this is best accomplished through Odin. For HTCs, Google your phone + ROM upgrade utility, and for LGs, use LG PC Suite.

Here at JOA, we get a lot of comments like this—” I can’t turn on Wi-Fi, Bluetooth, or Hotspot. How can I fix it?” Connectivity problems like these are very common. While it’s possible that the solution can vary by year/make/model/version, we can often take the same approach for most Androids.

Additionally, we can also start out with the most common, simple solutions before we must resort to more drastic, challenging measures. If the general basic solution does not work for your device, or you have an unusual problem, there are ways you can frame your questions that will yield better results. This information is helpful if you are posting your question in a forum or the comments section.

Discuss any solutions you have already tried. Include the version of your Android, which can be found through Settings > About Phone or About Device. Android’s make/model name is imperative. If your phone was working fine before, and suddenly it’s not, something changed. It might not be a change you initiated, but if it was, this is also very helpful information to those trying to help you.

The change might be an action that you think is unrelated, but most problems boil down to two things—an app is misbehaving, or your operating system is. So, if you have downloaded any new apps, or you have updated your OS, it’s worth mentioning. For that matter, any changes to your phone could be relevant. You might think that your brand new case has nothing to do with your display problems, but it’s best to leave every possibility on the table, to begin with.

Basic Troubleshooting – Fix Your Device Easily

All problems with Android devices are tiresome. And these are just some of the common ones. But we publish basic troubleshooting articles for specific Android makes and models all the time, so you can also do a search or keep an eye for your device.

Also, the solutions described can vary by type of device, so if the details for the method aren’t listed, perform a search on our site. Or if they don’t seem to match your Android, search the method and your make/model and you will probably find instructions on JOA.
