I got the beta update last night on my Nexus 5x it gave my device a brand new life . I so far can't see any bugs or problems the phone functions better than ever . I was considering selling it but now it's a keeper!
The only bug so far is within WiFi settings. If you go into WiFi (looking at the various networks) and then click on the cog wheel it will crash. Minor bug -- I reported it but otherwise 7.1.2 is working well .
Nexus 5X, 16GB
New behavior for 7.1.2.... the volume up and down buttons become totally unresponsive after some time (like a couple hours). I have not yet discovered the trigger. The only way to restore them is to press and hold the power button until the phone shuts off (to simulate a battery pull). A simple restart does NOT restore the buttons. Feedback sent.
Anyone else, or just me? This never occurred in previous beta or released builds. If this persists, I might have to revert to non-Beta. Having non-functional volume buttons is not workable.
