Recently my battery has been rubish. And I dropped my IPHONE 6S and it wouldn’t turn on stall, so I got a new screen and battery for a 100 pounds… my phone has been really laggy and slow.. but I use this app called YELLOW so I dont know if that is causing it… please help
Perhaps do a backup of your iPhone through iTunes, restore the phone and restore the backup of your iPhone made from iTunes backup? Are you refering to touch screen not responding correctly? Stops responding? It could just be a bad screen.
