I have reported camera instability issues in this build... See Post > has .576 broken the camera app.Just updated my 630 (512mb with DHTUpgradeAdvisor) to 14393.576. I'ts working fine except for a few problems (which has been there in the previous build too).
The camera controls don't work properly when set to max value, and the manual shutter speed don't work in any level, it keeps auto.
The headphone buttons don't work, neither volume neither play/stop.
Sometimes after a few scroll down in the photos app, or onedrive, than scroll up, it crashes and closes the app. (Probably 512mb issue).
Zooming photos can crash the app sometimes (Probably 512mb issue).
I'm having issues with Hey Cortana too (950). Initially it refused to acknowledge me at all, though all other uses of Cortana and voice-to-text work fine. I got that part solved by turning off Hey Cortana, rebooting the phone, then re-enabling Hey Cortana. At least now it reacts.
But the "learning" part is broken. That's where it asks you to repeat some phrases to learn your voice. It goes through the process, and I can see it correctly reading my phrases with 100% accuracy, but it claims it's not hearing me. Very odd.
Luckily, I don't use the feature much.
I think only with factory reset.
Worst update ever. Camera crash phone,and phone run in loop boot. Take phone in charger help,but battery is on 76%.
