I installed android pay which made type in a pin to activate rthe phone, now I have uninstalled android pay but still have to enter a pin. how do I disable this please anyone......
A lock screen PIN? You may have to Clear Credentials in Settings, Security first, but otherwise it's in Settings, Lock Screen, where you would have to set the None or Swipe option.
Change the option on that screen (I can't give the EXACT steps as my device has corporate PIN lock requirements on it) to have no security. I should caution that doing this puts your data at risk of theft if you should lose the phone.
