I had my old iphone screen cracked and needed to swap it. Official retailers sell these for a much to high a price and I decided to gamble and turned to online stores for the first time. The order arrived on time and I was able to change the screen myself. Weird thing happened afterwards as the phone did not react to touch. I was blaming myself but asked the customer service just in case. They instantly offered a solution to my problem. Seems like it was a common problem and they helped me to solve it.
