Very disappointing to say the least!! I took my Samsung S4 in to get the screen replaced. This was OK but after the repair the WiFi and GPS did not work. Took the phone back 3 times to get fixed. They said they replaced the WiFi antenna which they charged me for. The phone still didn’t work. Not wanting to waste my time and with no confidence that they could get it right I did some minimal research and learned how to disassemble and reassemble the phone myself. When I got into the phone it was obvious that the antenna was not touched. There was no need to but I was charged for the antenna replacement. The problem was simply some contact prongs that were bent probably from the original attempted repair. A very simple fix. After my work the phone now functions perfectly. I would not recommend this repair shop!!! They are supposedly professionals but certainly did not treat me that way.
