Bugs and software issues, on Galaxy A9, A8, A7, A6, A5, A4, A3 or another Android device, can be easily fixed with either a cache wipe or a complete factory reset. For glitches, freezes, delays and lags, it is best to try the cache approach first and only later resort to the hard reset. That’s why we will first introduce you to this option, with a couple of general mentions before anything else.
Understanding your smartphone’s cache memory
We could jump straight to the part where we give you the instructions, step by step. But we are not really convinced that learning the steps without understanding the principles behind it would help you in the long run. When you really understand what this cache memory is and why you are doing what you are about to do, everything will get a whole new meaning. Later down the road, when your Samsung Galaxy A9, A8, A7, A6, A5, A4, A3 will manifest various problems, you’ll be able to tell, all by yourself, if and when you might have to clear the cache.
In simple words, the cache is where your smartphone stores temporary data with specific purposes. The cluster of data, whether it regards one app or more apps, or the entire system, will help the device access bits of information easier and faster. When the cache memory works exactly as intended, your smartphone will work better, switch from one app to another smoother. When not, all kinds of freezes, app crashes, and general lags might be experienced.
Clearing the cache is one of the firs things you should try before considering to completely remove an app or to factory reset the phone. We already suggested that there’s a cache memory for the entire system and cache memories for every single app. Coming up next, you’ll learn to deal with each of them separately.
To clear the app cache:
- Access the App Manager from the General Settings of the A9, A8, A7, A6, A5, A4, A3;
- Find the app that you suspect giving you problems and select it;
- Go to the info screen of that app;
- Tap on Clear Cache.
To clear the cache of all your apps at once:
- Access the General Settings;
- Navigate to the Storage section;
- Tap on Cached Data;
- Clear the cache without selecting Clear Data – the latter option will lead to losing all the information previously stored in it, like the username and the password, the preferences or other settings that you have personalized.
To clear the system cache:
- Turn off the Samsung Galaxy A9, A8, A7, A6, A5, A4, A3;
- Press and hold simultaneously the Volume Up, the Power, the Home buttons;
- When the Android logo shows up and the phone vibrates shortly, let go of the Power button and keep holding the two others;
- When you’ve entered the Recovery Mode you can let go of all the buttons and start scrolling down from the Volume Down button;
- Select the Wipe Cache Partition;
- Tap the Power button;
- Select Yes;
- Tap the Power button again;
- Wait for it to wipe the cache and reboot;
- Since you’ll still be in the Recovery Mode, select the Reboot System Now and this one will bring you to the normal running mode.
What else can you do?
Assuming you were suspecting a simple app cache issue and clearing its cache didn’t solve much, you can consider uninstalling the app itself. Then, you will have to reboot the phone and see if anything changes. Of course, backing up your files could spare you from losing anything during the reboot process.
If wiping the cache of one or several apps and then uninstalling those apps doesn’t help, proceed to wipe the cache of the entire system. If not even that one will fix your problem, move on and factory reset the Samsung Galaxy.
