I’m also a victim of Avechi incompetent repair team. Just a month ago I took my UMI device there for repair believing that they are the best in town. My phone had a cracked screen and I would have repaired it myself if it were not for the lack of a spare parts in town.
I scrutinized my device to ensure nothing else had an issue. One of the repair guys said it would cost me 6k since they had to import the screen, which agreed. After two weeks, they called me and told me that there was a replacement screen available and I should go and pick it up. After reaching their Kenyatta avenue centre, I checked the phone for almost an hour to ensure everything was okay.
To my dismay, two things were not working… well, properly working. The fingerprint reader completely blocked me from using it and when i asked them, they told me they replaced it, which they should not have done since it is not soldered to the screen and was working previously. When I asked for the fingerprint module they took out, they told me it was not available. As a rule, if anyone replaces a fingerprint reader, he or she should flash a new OS to ensure its in sync.
Additionally, my phone signal kept having trouble connecting and when I asked them, they told me that the area has a low signal coverage. However, upon paying them and leaving, since I didn’t care much about fingerprint (afterall i can flash it on my own to secure my data) I realized the signal problem was too serious to the point it never connected to 4g or 3g in a low signal area…like my apartment.
I decided to open up the phone myself since returning it meant additional cost (according to their rules “never leave with a faulty device after repair”). I found that they also replaced the antenna cable with a faulty one and I had to replace it with a new one myself. The screen has also popped out on one side its like they didn’t use enough adhesive to keep it in place. Bottom line, never trust Avechi for repair. My advice is, get a device which has a service center from the OEM in the local market, like Samsung or LG. otherwise, in case of repair, do it yourself, or get a new device. It will save you the headache
