Charger stopped working.
Repair took about 30 minutes. Everything was by the instructions. My only problem was getting the antenna connector back on. Finally snapped in.
Easy repair, which saved the cost of a new phone. Checked online and there are many sites with less expensive replacements. Reading the reviews however, it seemed like a lot of people had some kind of trouble afterwards. Decided to spend the extra $ to get an actual S4 part.
