Display Issues after battery replacment
so after i replaced my battery on my iphone 6s and put everything back together the display acts strange. some apps works with 3d touch and some dont. also when i push down for 3d touch colored blotches come up in that spot. however when the phone is unscrewed and just not put together everything works fine.
please help
