My iphone 7 plus screen suddenly glitches and multiple colored horizontal lines appears, it then restarts by itself. This happens quite frequently. Contacted apple support at first and they told me it was the battery issue, so I went ahead to change the battery on my own and its now at 100% health. Thought that solved the problem but it still occurs, although not as frequently as before i changed the battery. Could a faulty lcd screen cause this issue? If i changed the lcd screen will the problem finally go away?
