IPDA087: When I forget my screen password, what should I do?

A: Lock Screen Password——the pin/password/pattern you set in settings

You can factory reset the device via button combination, here is a link for your reference:

Or you can reflash your device, if so, please share your device serial number which can be found in the label, so we can share you the proper OS file and instruction.

B: Google account password

You need to contact your Google account staff to change your password via authentication information
