PIN screen and PIN have changed on Huawei P8 Lite with Android 7 When I accessed my phone yesterday, the PIN screen had changed (presumably through an automatic software update). I put in my pin and it didn't recognize it.  I have not changed my pin. Luckily, I have fingerprint control set up so I can use my phone.  My worry is that sometimes the fingerprint recognition doesn't work. If this happens, I have lost my phone!
I have searched for info on the PIN changing by itself but Android/Huawei are not admitting to this happening. It is suspicious that the PIN screen has changed at the same time as the PIN changed. Does anyone have any information on this please?
PIN does not change automatically. And to remove pin, you need old pin.
You are able to access phone. So first take backup of the phone and restore phone. This will remove pin from phone. After that you can set pin. If you are not able to access phone then you may loss data.
Some application and software can recover lost pin.
