I currently installed a lock screen app on my tablet just because it's BTS. I haven't done anything and just installed that app then opened it. It asked me to change the password but I didn't so I just closed the app. Btw I don't know what the original password is. I turned off my tablet and opened it the next morning after charging it and now that lock screen app shows and I can't open it ;A; Is there a default password for every tablet or are they all different. They are just 4 btw, i tried 1111, 0000, 1234 and every numbers but it won't work. I'm not connected to internet at all so I know I can't use the google account options I found. I can access the files in my tablet through connecting it to my laptop but still I don't know how to open my tablet. It won't shut down either. Please help me with this u n u
