My ipad is cracked badly and it’s glitching!

background info:

so a few months back (like 2-3 months) my dad got very mad (unexpected) and my ipad was on the table. he threw my ipad very hard into the floor (and the floor cracked along with my ipad). the corners of one half of the ipad was cracked (the other half wasn’t cracked as badly). and surprisingly and fortunately it still works (everything was normal except my microphone doesn’t work and the camera was blurry bc my mom had to tape near it and it sorta covered it).

so a day or two before, it started acting up. like i tried to unlock my ipad and i pressed one number (passcode) and the ipad itself just started spamming the passcode and i was forced to close it. i tried again and once again the ipad started spamming the passcode numbers and the try again after 1 minute lock came on. so i left it alone cuz i thought it would fix itself after a night. so yesterday morning i opened it, thinking it fixed itself because the passcode part had no problems. then after a few minutes, it started acting up. i went into safari— the search bar just went up and down and up and down (it wasn’t spamming letters it was just the screen). i tried roblox, went into adopt me, the starting screen kept on spamming me, every time i would press no the same question/sign would pop right back up (it’s not supposed to). for ex: it would say do u want to teleport to the hat shop yes or no and i would press no but the same sign kept on popping up so i couldn’t even play. the screen was moving itself. (spamming letters on my keyboard only happened once, just the passcode.)

help me is it just broken? yes i’ve tried shutting it down.
