The issues are legion. First thing I noticed was the addition of bloat. The "stock android"was a main selling point for me, but I do not feel they delivered. The ultra fast charging has been nice on occasion, but I think it's done more harm than good: the battery deteriorated faster than any phone I've had before it. I've had lots of issues with the usb-c port, it keeps spitting out cables, occasionally doesn't connect properly. The behind-the-screen fingerprint reader is a really cool feature, unfortunately it's so unreliable I've stopped using it completely since it's faster to use the pin code than doing 8 scans of my finger. Lately the power button has stopped working which is super annoying, if I run out of batteries my phone is dead until an alarm rings, which turns it on again. The sound slider is a cool idea, unfortunately it interacts weirdly with several apps. The worst of which is it opens "find in page"in my web browser any time I touch it. Oh and it became loose and occasionally switches on its own, but that's wear and tear I guess... There is so much wrong with this phone...
