[Device Reviews and Information] avatar4:
Well, I can NOT confirm battery stats but Power holds nicely. 6-7 hours of xcom no problem and theoretically 15-18 hours OST in light tasks.

Battery is still badly calibrated, I had the same issue in 5.1 with calibration, but you can just clean battery stats and start with clean calibration. Downside is, you have to do couple of full discharge cycles to get good data but its doable.

Lag on screen never occurred in my case but I only write with one hand so dont ask me about it.

Heating is not an issue in 6.0 mainly because currently fast charging is broken. In 5.1 it was warm but nothing serious, max 50 deg C on battery sensor.

Gpu is NOT the best (its enough for me), but personally I dont know ANY android 3d game that's even decent (except xcom) (its just me, Im ex PC master race and all that) but 2d works nice.

As to MM update. Things that are vanilla AOSP work, so building rom from scratch and putting inside mediatek kernel Ulefone knows how to do (basic copy paste in code) . Problems are with custom things and finetuning. Ulefone DEFINITELY does not employ any real programmers. Their custom functions like gestures and led notification (how friking hard is it to program led with 3 colors and 2 stages + 1 off stage and max 2 gui windows) and all that are lacking. Looking inside config files you can see mindless copy pasting from different platforms, trash from old drivers, trash from different platforms, just basic hack job.

But dont get me wrong, vanilla AOSP stuff works well, really well, problems begin when they try to "improve" things (like fixing standby battery consumption in 5.1 by killing all background processes).

Also, speaker in the back and no speaker in front, this is stupid. When phone lies on table, you cant hear it ringing.

Also also, am I the only one that thinks that screen is great? You can even lower its brightness to max in gravitybox and use it nicely in dark room. Viewing angles are great, colors too, am I wrong?

Camera is meehh. I cant set manual focus on it so it has very limited use for me. Photos look good but there is noticeable artifacting/noise when you zoom.

Gui is hell fast on 6.0.

Real glass instead of plastic garbage on screen is nice too.

Bezel is ugly as hell. Ive got black version and it does not show much but I still can see it. Other people dont but I know where to look :).

Another stupid idea, 2.5d glass. Try putting screen protector on that thing. But apple has it so everyone has to have it too.

Gps seems great, indoor signal from 11 satelites in cloudy day, thats enough for me (on 5.1 sometimes it was loosing signal for 1-2 sec so while you were driving, you could potentially miss your turn).

So hey, this is my impression. Dont give it too much credit, I mainly use budget devices so I don't really have better comparison. But dont get fooled, this IS budget device but its my first budget device that has any kind of after sale support (mainly more than 2 updates).

1 thing bothers me. I dont realy know if 5his phone has 3gb of ram as advertised. All things point to that its true, but while I was digging I found out that this phone reserves 1.4gb for swap space, thats too much in my opinion (I base this on kitkat roms, so here it might not apply)
