Your phone will occasionally reboot, no matter how careful you are, so it’s best to expect this and not have it disrupt your plans. Maybe you’ll get so engrossed in a task that you don’t notice the screen dimming and then lighting up again, or maybe you’ll just want to give it a quick kick to get it working properly. Whatever the case may be, it’s frustrating when your phone gets in the way and makes things inconvenient. For those with Android devices, there are numerous reasons why your phone might reboot, and while some of them are harmless and simply a side effect of using your device, others are caused by apps and/or device configurations and not anything you did. In either case, it’s best to find out why your phone keeps rebooting and deal with the issue so it doesn’t happen again.
Check The SMART Data
One of the things Google does really well with its smartphones is let you check on the state of your device’s health at any time. Even if your phone is not showing any problems, going into Settings → Battery and checking the charge and activity levels can give you an idea of what’s going on and whether or not your phone will be able to serve your needs. If you’re curious as to why your device is rebooting, there is an easy way to find out: access the Device Performance section of your Google account and take a look at the SMART data (Self-Monitoring, Analysis, and Reporting Technology). This is a collection of information about your Android device that helps Google provide you with the best possible experience on their platform. One of the things that the SMART data will tell you is the reason why your phone keeps rebooting: faulty software or hardware.
Check The Logcat
Another important thing to do if you’re curious as to why your phone keeps rebooting is to check the Logcat window of your device. This is an important source of information that can help you track down the problem. You’ll find numerous problems and errors generated by your phone as it runs, including anything from authentication issues to connection conflicts to general errors. You can open the Logcat window, which is usually found in the Apps → System section of your device’s settings, by entering the command *#*# logging into your device’s main menu and then selecting the Logcat entry. If you want to find the answer to your question more quickly, you can use the search bar at the top of the Logcat window to look for errors and issues reported by other users that may be relevant to your situation.
Disable Unwanted Applications
If you’re finding that a particular application on your phone is causing it to reboot, it’s best to remove it and then disable it so it doesn’t bother running when you use your device. Even if you don’t have an issue with the particular application, there are dozens more that you could install on your phone that will do the same thing. Why load up your phone with unnecessary applications that could potentially cause it to reboot? It’s best to remove them and not have them clog up your device’s memory and slow down its performance.
Clear The Cache
If you’re finding that your phone stays powered off or slows down considerably after being on for a while, it’s best to clear the cache from time to time to let the device’s hardware and software operate at its peak. There are several ways to clear the cache on your phone, but the easiest and most effective method is to just reboot your device. When you first turn it on after clearing the cache, it will load everything back into memory and return your phone to its original state. This is a simple yet effective way to increase device performance and keep your phone powered on for longer.
Update The Firmware
Updating the firmware on your Android device is another way to increase its performance and longevity. Sometimes when manufacturers make changes to the operating system or hardware of a device, it causes a need to update the firmware. This is typically a one-time thing that has to be done to every Android device that gets the update, but it’s worth it if you’re running into problems.
If you’re running into issues connecting to certain Wi-Fi networks even though you can connect to other networks just fine, it’s best to disable Wi-Fi while you’re using your phone so the network authentication and traffic is not interrupted. Sometimes this can prevent devices from connecting to Wi-Fi networks that were previously accessible and available for use.
Hopefully, none of these tips will cause your phone to reboot often. Even if they don’t, they’ll help you figure out why it’s doing so and, hopefully, fix the issue. For those with security concerns, disabling Wi-Fi may be a necessary evil, but at least you’ll know why it’s necessary. Always remember to update the firmware on your device and clear the cache as needed to keep your phone running at its best and, most importantly, avoid any problems caused by foul play.
