I updates to the latest software as suggested, so its a tiny bit better, but still draining quite fast, please repair it guys, that is very disturbing with a phone that is supposed to be a flagship
UMi engineers do an excellent job of designing very beautiful phones. But they all suffer from battery and screen problems. If you look through forum at all the other UMi releases you will see people having the same problems and begging for help from the UMi engineers. UMi just tells people to upgrade the ROM. This actually worked for me for a while. I only owned the phone for less than 2 months before the problems started showing their ugly heads.
I find it a very strange business model to release phones over and over again all with the same problem. How many people have the skills to upgrade the ROM in a mobile phone? The answer is very few!
If you are a;ready having problems with your UMi - and you have the latest model -send it back. If everyone sent back their phones instead of chucking them in the rubbish UMi may get the hint that their engineers ain't doing their job.
