[AC Question]

so I posted a few days ago , so yes my android tablet has been acting very weird all of a sudden. I've done a reset, reboot everything possible but the symptoms are whenever I touch the screen I have to press it really hard, sometimes it's lagging so slowly I get frustrated pretty quickly and I really want to resolve that problem. as I said it happened overnight a few months ago but I think its a virus for some reason that I cant even log in to anything sometimes it freezes

please any help.
