I forgot my pin password to my tablet. My tablet is some type of ONN. Model that is supported by android. It works really weird because I tried to factory reset it but it literally doesn’t work. Every time I press the volume and power button at the same time it doesn’t do anything. Google and android website/support is no help so someone please tell me what do because I can’t keep guessing my pin :(
