My phone had all kinds of problems such as freezing up and restarting by itself for no reason.
Connected with Musha through Yelp and his respond was almost instantaneous.
Took the phone in the next day and he spent almost 30 minutes checking my phone and giving me advises. He gave me few suggestions including deleting some harmful apps and resetting some settings.
As my phone is quite old not all problems were solved.
Instead of trying to get me to spend 50 to 100 he settled for no charge.
5 stars for personality and customer service.
Highly recommended!
