I'm sure you've already encountered this: the application suddenly starts to crash. Unable to connect to the network. The phone does not respond or is slowed down. What now?
If we are the victim of a similar situation, is if very likely because after an update the new version of the application is not able to work properly with the old data.The solution is either to uninstall and reinstall the application or to delete its data (if it is an application that we cannot or do not want to uninstall - for example, a system application or an application installed from an APK file).
When it's really bad
The phone will notify us what will be removed. Before this step, make sure that your backup is working and up-to-date.
Press the button to continue.
The phone will then ask you for a password.
Then the phone restarts, complete deletion takes place and after a long time the device starts up in the wizard for the first start. It's like unpacking your phone.
When it's the worst
What? Worse than a complete erase? Well, because we need to get on the phone to the previous procedure. But what if the whole environment is so unstable that we can't get into the settings? In that case, we can reset the phone to factory settings.
We proceed in the same way when deleting the cache partition, but instead of the Wipe cache partition, select Wipe data / factory reset. As you can see, a red warning is displayed. If you confirm the selection, the phone will be completely restored and then the first start-up wizard will start.
You may have wondered: what's the difference between doing a factory reset from the setup menu and from recovery? The difference is that when we go through the phone menu, we enter the password and the phone notes that the deletion was correct. If we go through recovery, no password is entered and the phone will want it for you during the startup wizard.
Be very careful about this, and if you are selling your phone, always perform a renewal from the phone menu. If, on the other hand, you buy a second-hand phone, go through the guide and make sure that you do not encounter a barrier in the form of a request to enter a previous account and password, it could be hard to find.
And yes, now is a good time to make sure you know the accounts to which the phone is logged in and the relevant passwords. You will definitely need a Google Account and you should also be signed in to your Samsung account. Don't be ashamed to write down your account and password, ideally on paper.
Of course, I wish you never needed this article. But if you do, perhaps it will save you a moment of searching and even visiting a service.
