ive had an issue with my iPhone 6 where the screen started glitching and would randomly tap parts of the screen without me doing it and the phone only charges now when the battery is completely dead and there is no 4g anymore it just says searching and the phone is really slow now, does anyone have any ideas??
Did you try shutting it down and restarting it? If no, then do it. If yes, still the same then I would suggest to go to a repair shop and let it checked. See how much they charge you for it. Usually shop keepers charge way more than normally. So, compare the repairing prices with online platforms too such as Alpha SmartPhones, Ebay, Amazon and more.
