hi can anyone help. I had my iPhone 7 screen replaced last week as it was cracked. Now a week later I can’t log on as my lock screen number pad won’t work. Only numbers 3, 6 and 9 work and I can’t slide to unlock or answer calls. Went back to shop who repaired, they say there is now a crack inside the screen and the phone must have been dropped causing this. Therefore this is why screen not working. I’ve tried restarting to reset but no good. Any help would be great thank you.
