my phone arrived last week via Amazon, the delivery from Gearbest still didn't arrive yet.
The version was 20170718 already, so I didn't update, since I didn't run into any of the errors that the august updates are addressing.
I already had it with me on a open air festival last weekend and it got a little wet through rain and sweat, but worked fine. The touchscreen was good enough to clearly recognize fingers while raindrops were on it.
All in all the phone works pretty well, the touch delay is very low, the performance is slightly lower, than my old Sony Z3 Compact, but way higher than my Doogee X5. The camera quality is mediocre at best and bad at low light, but I didn't expect the photos or videos have the same quality as my old Sony made.
Fingerprint sensor is working OK, sometimes you have to retry 2-3 times, but I don't call that an issue. Didn't try using more than one SIM at once. The file system on my SDCard, Sandisk Extreme SDXC 64GB, was declared dead by the BV8000 Pro, though I was able to read it in my old phone and a card reader attached to my PC without any problems, had to reformat it to use it in BV8000 Pro.
OK, now for the issues:
1.) NFC: I can't find a shortcut in the area, where all the other switches for WiFi, Flight Mode, etc. are. (see attached screenshot).
2.) Poor Bluetooth range: There are no problems in connecting to Bluetooth Devices such as JBL Charge 2+, BT Cassette adapter or Renault Factory Radio with Bluetooth, but I have to stay inside a 1.5m radius or even less, else the music starts stuttering and eventually stops playing (Player: PowerAmp). This has nothing to do with Dura Speed or closing apps in background, since these options are turned off.
3.) Videos are stuttering sometimes, also when playing on PC (using VLC Player).
4.) The adaptive display brightness is rather uncomfortable: When it's getting dark, it starts adjusting the brightness between 0% and 15% or so, there are no nuances, it's either zero or fiveteen. I get that nearly every time I'm in bed, playing a game or watching news and when the picture is very light, my skin reflects the light, the display gets brighter. Is the picture darker again, the display gets darker, too. That's annoying.
I also had a few camera issues, but these were based on a conflict with another app called Rotation Control pro.
