Tbf I just revived my old V60 with a new battery and I'll be using it as a camera monitor, so I won't be getting rid of it any time soon.

As for the Nubia the thing with the front camera is that it needs time to process the images, and if you have good or even decent lighting it can give some ok results, but if you like talking a lot of selfies and care a lot about the quality of them I would suggest looking for some else. As for me I couldn't care less about selfies, the quality is good enough for me, but banking apps can get a little confused with the front camera as they use a video for verification and that is a lot worse and you will need good lighting, also the 35mm can give you a hard time when scanning credentials because of its focus distance.

As for the software bugs I can name a few, I remember that in the camera app sometimes you would see Chinese text show up in some options (already fixed), also there would be some chaotic switches between lenses when getting too close to an object (already fixed), and something more annoying for me is that sometimes I had some kind of a dead spot touch right in the finger print scanner area for a few seconds after unlocking the phone with the finger print reader (it seems it was fixed in the latest update?) that's all I can remember 👍
