Android problems may be common from one device to another and that’s a good thing because it allowed developing some general troubleshooting options and fixes. On your Samsung Galaxy J7 smartphone, for instance, you can always initiate a complete factory reset or a wipe cache. Both actions are designed to solve a wide range of bugs and glitches, software problems in particular.
The difference is that one of them will just delete everything to get the problems out of your way while the other one will only clear the cache. Also important, one of them will work better with more severe issues, usually when the phone is unresponsive, and the other one is more suitable for whenever the device manifests glitches, lags, delays, or freezes.
We will focus on the second option, the one with the cache wipe, for a very obvious reason – it gives you the chance to fix the problem without having to start configuring the Samsung Galaxy J7 from scratch.
If you’ve read any other tutorials on Android troubleshooting so far, you must already know that the cache memory is of two types – you have a cache for each app and a cache for the operating system, also known as the system cache.
Both of them store temporary data to help you switch between apps or handle processes and services. Knowing all that, it becomes obvious why clearing the cache should be the first thing you consider when apps are working slowly or the device manifests all kinds of lags.
You will also be able to tell, all by yourself, that you should try to clear the app cache when only a particular app is giving you problems, or to clear the system cache when problems manifest randomly.
To clear the app cache
- Go to Settings;
- Open the Applications Manager;
- Find the app that doesn’t work properly;
- Tap on it and access the App Info screen;
- Use the Clear Cache option.
Have you followed all these steps but nothing changed? You can take into account the possibility that the app itself is having problems. Proceed, therefore, to uninstalling it and then reboot the phone. It wouldn’t hurt that you also back up everything before you start with the suggested reboot instructions, protecting your data from any accidental damage or loss.
To clear the system cache…
- Power off the smartphone;
- Tap and hold the Volume Up, Power, and Home keys:
- Wait until you see the Android logo:
- As soon as that logo appears and you feel a short vibration, release the Power button;
- Only release the two other buttons when you have entered the Recovery Mode:
- Select the Wipe Cache Partition option with the Volume buttons;
- Activate it with the Power button:
- Confirm with the YES option:
- Tap on the Power button one more time for the process to start:
- When it finishes and reboots, use the Reboot System Now option to get out of the Recovery Mode.
