Hi everybody,

Well It's been already a week with this device, so I think I have already some experience with it, so I can give some feedback:

Despite that the HW in this phone seems to be quite acceptable, there are some problems with the SW, which makes the user experience not as good as it should be. But I have to say that the telephone is perfectly usable for everyday use (at least for my use), the most common problems, are the one which are written here after:

1- The battery is named as 4000mAh, but I have to say that the battery is bad managed and it's not showing the expected life for this capacity. Yesterday the issue a new FOTA update V3.03-20160423, in which they promise to fix this. At the moment it shows some improvement, but I cannot say since I did not have time to really test it.

UPDATED: Well after some testing, it seems that it behaves even worse than before, unfortunately, check post 14:

2- The screen; well this is one of the bigger problems, they are appearing (to majority of users) some white stains in the screen; in the official web page they mentioned that it was caused by some defects in the screen manufacturing process and UMI said that screens were glued incorrectly but they also stated that they corrected this problem in the following batches of the UMI Touch and offered to be helping in the process for getting a replacement. But in my opinion, there are not completely transparent here, in the official forum they were constantly deleting the posts where this problem was mentioned; and for me it is very interesting that everybody who has this problem, they have the white spots in exactly the same place on the screen (burnt screen because of bad IC dissipation ? )

Anyway here under you have an example of the white dots:

3- The touch sensitivity is not good, sometimes for writing texts and so can be a bit annoying, but definitely they have to tune this too.

4- Attention there is NO Notification LED anyway there is some discussion about using the soft buttons as notification leds, let's see if UMI hears the users....

5- The WIFI, at the moment for me the wifi is quite unstable, the signal strength is quite poor if we compare with other devices, as for example Redmi2; I guess this is something they should continue improving by software.

6- The accessories included (the adapter and cable) are the worst quality ever, the cable it broke after the second time I plugged (literally ) , and the adapter I was afraid to use since it was reported for many Forum users that it started to smoke and stink until they stop working. At least one person in the Forum complained that after the incident something happen with his/her mobile. So better don't use the included adapter & cable!, better safe than sorry.

7- The camera should be good quality, but it showed some lag when capturing pictures, for example if capturing with HDR and there is some subject which was moving there will be "ghosts" in the picture. It suppose to be fixed from the yesterday's FOTA, but I did not try it yet.

8- There were some people also mentioning that the GPS was not accurate and so, from my experience from the last weekend, I have to say that it wasn't that bad, actually Google Maps was the only one not so accurate, I was using HERE and WAZE and no problem.

Conclusion: It seems to be good hardware phone, but they are a few problemsuntil they polish a bit more the software I would not recommend it to buy, it seems that they are in a good way for fixing the problems (they release quite often the FOTAs) but still I would give more time to see how UMI behaves..

I hope it is useful at least for anybody :) :)

Cheers
