It's a great phone and I'm not just looking for flaws but rather just my experience. Like I said it takes great photos except the start up time on the camera is pretty slow and with indoors the shutter and auto focus is very slow too. Slower vs. the S7E, iPHone 7+ and Google Pixel. The V20 also suffers from this but not as bad as the G6. And Yes, I have all these phones to compare it to.
People need to be aware of these issues as none of the reviews I've watched mentions this as all their photo comparisons are all done in day light or very well lit situations. If the reviewer does show low light samples they are usually standard still shots or landscapes and don't mention the slow auto focus.
