The telephone performs excellently, but there are bugs. The battery loses too much charge, while in idle mode, so you cannot rely on it for longer than a day. There are a number of other software bugs as well. I changed the original software for a Plunk HERO one. The battery problem was not fixed and another major problem remained unsolved - sometimes the phone does not signal neither by sound, nor by vibration for incoming calls. Of course, if I can see it, the call can be answered. The fingerprint scanner works very well, but since it is small, one must get used to using it. If you save four prints from one and the same finger, there won't be any cases of unrecognized prints. If these problems are fixed, probably with another ROM, the telephone becomes of perfect value.
