[Device Reviews and Information] axelnanol:
thoughts so far

Hi all, have had the phone since Tuesday so figured time to give my experiences so far.

First up, some comments on Ulefone-specific features.

Battery life is probably not 4 days for me but it's better than most (and way better than the 6 hours I've been getting from my day one Nexus 4 recently!). One day of heavy usage and another of light perhaps?

U-launcher is a strange one! Stylish standard theme, inoffensive features, really nice camera widget, absolutely terrible theme store. I've gone back to Nova, but I do find myself with a soft spot for Ulefone's offering.

Fingerprint reader is ok. Would be much better if it could read your fingerprint from any angle. Needs a lot of work to get it to the level of functionality I'd like, e.g. context sensitive actions (am thinking tap when unlocked = back, double-tap when unlocked = home).

Build quality is absolutely top notch. Really well thought out case shipped with it too.

Touchscreen & general speed is really responsive. Along with the build quality you can easily pass it off as a high end big brand phone and wow all but the worst pedants.

I could not begin to tell you what 'Gesture Unlock' or 'Smart somatosensory' are under Settings.

At one point when rooting I ended up at a completely Chinese text UI. Would highly advise people root purely to not have to use that when things go wrong later down the line.

Sound quality from the headphone jack has been variously stunning, in the case of an HD video on YouTube, and very quiet, in the case of a call I took earlier.

So next I'll mention some glaring annoyances that Megthebest's TWRP + SuperSU + Xposed + GravityBox can fix.

Physical buttons are the wrong way around: back should be on the left, and menu should be on the right and actually be recents (GB: Navigation Key Actions)

Backlight is very dim, nothing we can do about that but at least it should always be on when the screen is on (GB: Display tweaks > Button backlight mode Always on while screen is on)

Statusbar tiles quite sparse even for LP (GB: Statusbar tweaks > enable pretty much everything)

Adaptive brightness just seems to be always very bright (workaround: GB: Statusbar tweaks > Enable brightness control)

Finally some outstanding issues.

No dark theme (or any theme support outside of U-launcher), I really miss dark material :(

The camera button on the side. It's hard coded to launch the Ulefone camera app, and I keep pressing it accidentally. Long press or double-tap, or even disabled completely would be preferable.

Due to being on an O2 business contract, I'm limited to 3G at the moment. I'd be interested to know if anyone else who falls short of the 4 day battery life claim is also on 3G. Am going to drop the setting Mobile network settings > Preferred network type from 4G to 3G and see if there's any change.

Once you put an SD card in you don't get the breakdown of storage types for the phone's internal memory anymore.

Probably more a general android annoyance, when I put my SD card in, it formatted and mounted that as sdcard0, and remounted my internal storage as sdcard1. Cue 2 hours of file management to move everything back to the places where each app expects things to be.

Would be nice to push the MT6753 to 1.5GHz and run a 64 bit OS but no idea if these are pipe dreams.
