I took a Galaxy edge phone to replace the battery. I agree on the price (cash only) and I left the phone for couple of hours. Hassan assured me that was a new battery and it all worked fine. Heactually told me that the phone doesn't heat anymore. On the second day I start suspecting something. The battery was loosing a percent a minute, using it. On the 6th day, it started to shut down unexpected, going for 39% to 1 %. I called them and he said that it's a software problem. I decided to open the phone myself and they used an old battery, clearly from another phone with a small sticker of go in top of it. Consumers be aware of their parctice.
