Guys, I just can't stand Mate 8 poor camera auto focus, sometimes I need to take picture of important details in close range, but couldn't due to the bad auto focus, I tried downloading many camera apps, but it doesn't fix it either, any solutions?

It's not a problem of the autofocus, it's a limitation of the lens that cannot focus obiects that are closer than a certain distance (approx 7-8 cm). There are DRLS lens that cost more than the Mate 8 that have the same limitation. If taking close up macros is a must, than there are other cellphones the allow you to get closer to the subject.
More in general, I read in the past a number of complains about the Mate 8 camera and because of these I've waited more than 2 months before deciding to buy one. I have 2 Canon DSRL, a Sony RX100 and a few compact cameras (Canon, Panasonic, Kodak) so it's obvious that quality of the camera for me is one of the most important features in a smartphone. After getting the Mate 8 I must say that I was surprised by the general good quality of the pictures I could snap. After about 6 weeks I would rate the camera with a score around 7/8 (out of 10).
Here are some unedited pictures I took, you can judge by yourself:
https://flic.kr/s/aHskyvuYxshttps://www.flickr.com/gp/48761054@N03/Y77681There are better camera phones out there (Huawei P9, Samsung S6 and S7, LG G4, G5 and V10, iPhone 6 and 6S to mention a few) but they are not without faults and often the quality of the pics taken with the Mate is VERY close to them.
Mate 8 has a good general purpose camera, the focus is reliable, the lens is good (I cannot see a significant image degradation at the corners of the image), it has an effective optical image stabilisation, the exposure is good, the colours are natural and even in low ligth and high ISO the pictures are comparable (if not better) to the ones taken with a Canon or Panasonic compact camera.
Limitations of the camera?
- HDR mode is not particularly effective (could be fixed with a sw update)
- not the ideal camera for macros
- some noise is visible even at low ISO in areas of homogeneous colour, in particular the blue of the sky. This is a choice by Huawei in order to preserve the details of the image. The noise can ne easily removed with very little degradation of the image by post processing with sw like DeNoise or Noiseless (for OSX).
- sometimes the white balance (particularly with a cloudy weather or in the shade) is not spot on
- cannot easily freeze fast moving subjects. For that you need a DRLS or maybe you can get more successful shots with the Samsung S7 camera with its new Dual Pixels technology
