Never buy another UMIDIGI product
I purchased my first UMIDIGI phone over a year ago and almost a year to the day the main speaker failed. I purchased it through Amazon and they referred me to UMIDIGI Support. It took forever for them to get back to me to open a case for my problem. Again, long delay with no answers and then was advised that my phone was out of warranty period. I started to check out other reviews on amazon and found a few others with same speaker failure problem. I contacted UNIDIGI again and they opened another file and after several weeks came back with no solution for this problem. Will never buy another UMIDIGI product.
