Go into Recovery mode. Press and hold down the Volume Down button and keep holding it, then press and hold the Power button as well for a few seconds, and let go when you see the Android mascot on its back on screen.
Go into “Recovery Mode” as we guide you at the start. Find “Repair Apps,” which is usually located at the end of the list. Press the power button to select “Repair Apps,” and unlike the first process where you don’t have the option to confirm or deny with a Yes or No. After choosing this, the phone will reboot, and once it's back on, you will see “Optimizing apps” and the number of apps that your phone has show on the screen (depending on the version of your software). Once the whole process is over, you can start putting your PIN into the phone and start using it just like nothing happened "hopefully"
