Thanks for You all! I unfortunately live in "far far away Europe country" where it's hard to purchase bq or meizu... that's why I've chosen Nexus as it is still avaliable here Thank You for explanation, I found out that flo and deb has camera on the right side in the top bar and previous 2012 model has it in the centre of top bar. I also asked resellers for pictures of fastboot mode to make sure. (The problem was that they marked their devices as just nexus 7). Mentioned problems (with bluetooth) are acceptable for my needs. In future I wish I have pinephone and pinetab but for now they are not ready. Once again big thanks I'll mark thread as solved.

@doniks , Oh wow, thanks for this information about the Nexus 7 2013 wifi. I have one that I have not used in many months. Time to get it out again : )
