My on-screen keyboard has stopped working, and I cannot login without
My Samsung tablet, which i have had for years has recently started not working. First off my tablet requires a manually written password to login after a restart, and the on-screen keyboard does not work anymore. This makes me unable to do practically anything.
Furthermore a weird sort of Blackscreen has started appearing right after a restart and lasts for around 2 minutes.
Appreciate any help!
It says SM-T805 on the back, if that is of importance.
