hi i have an iphone 6s and it’s alright.But all of a sudden it started acting up.I can’t close off my tabs or slide and see how many tabs i have.Also when i swipe down its swipes down slow and i try swiping down fast because it’s slow and it just speeds up.Also on my home screen i can’t swipe next or before to view my apps,now i have to tap on little dots to swipe what apps i want.And for tiktok i can’t swipe down either so now i can to refresh every video to watch. My screen isn’t working,i can’t zoom in or zoom out,and like i said i cant swipe down and swipe up most of times but when i do its very slow.I tried powering off my phone so many times but it wouldn’t let me.Not also that i can’t go on some apps.Can anyone pls help me?I didn’t damage my phone,it just started acting up.Please lmk what’s wrong.If i have to go to apple to fix it,i completely understand but idk how much i have to pay and there’s no apple near me so that will be difficult.My carrier is tmobile and i been having this phone since 2018.Is there a way they can replace my phone with a new phone for free?There is no way i’m paying for a new phone.
