It’s very simple to upgrade your Android phone or tablet to the latest available version, but if you don’t do it correctly, you will encounter big problems and you won’t know what to do, to save your device.

So, there are three important steps that you must take into consideration, so follow them and you won’t have any problems.

First Of All, Back Up Your Data

If you don’t want to lose all your files, you’d better use a cloud service and back up your data. We recommend Helium, Google Drive, Dropbox, but there are also many other free applications which offer enough space.

Makes Sure The Battery Is Charged To At Least 70 Percent

If you don’t want your phone to “die” during the installation process, charge the battery or make sure it has at least 70 percent juice left.

Another advice is to take screenshots of your home screens so you will know what it contained before the upgrade. You should do this if you’re using a stock launcher, but with an alternative Android launcher, things are simpler, because you are allowed to save your home screen preferences. By doing this, you will remember what to use when setting up your device from scratch.

Wipe Cache/Factory Reset

This isn’t really necessary, as some would say, but we suggest you to clear the system cache after installing the firmware, because you will get rid of the performance issues and the battery drain bugs that you’ve experienced in the previous version.

If you still can’t solve these problems, the ultimate solution is to perform a factory reset, but not before you have all your data backed up in the cloud. You will need to reboot into recovery mode by turning off the device and holding the Power and Volume Down buttons in the same time.

After whipping out the cache partition and performing the factory reset, restore your backup and set you’re the home screens.
