Tested some display unit at senheng, I can't help but to think the selfie camera out of focus issue is a hardware defect, namely lens misalignment. All demo unit took superb selfie. I HOPE it's just a firmware issue!

Guys, whats the highest power consumption portion of ur phone. Mine's the screen which sucks up 40% on average. Its kinda weird isnt it? Since im always doing something like browse chrome in 4G, games etc.

I feel weird cos my previous phones were always something else that sucks the most power.

First time on amoled here but shouldnt it use less power? Also switched to basic mode along with using dark wallpaper etc.

if only the AOD could display fb and whatsapp if got messages and how many just like calls and sms

Just had my first auto restart. I was playing Spotify over Bluetooth, and browsing using chrome and chatting over whatsapp. All of a sudden, the phone restarted by itself. Temp was normal though. Hmmm

What's the problem with the calculator?

I'm exactly on the same ship as you. 
When I was on iphone 6 plus i basically left everything open from wifi to 4g and even location. Now switching on wifi at night will drain my battery roughly 40-50% of my battery overnight (which is horrendous compare to you if I have to say). I suspect the fb,whatsapp,messenger app wakelock is causing all the draining. I never factory reset since I had my device.

but hey, i love the fact that my s7 edge keeps my background app running and every other thing about this device literally. So I practically don't really care about my battery life and just use it the way I like it. Don't worry about the 6% drain overnight and this phone charges so much faster.

Anyway, I guess there is this thing called pros and cons. 

//Edit: speaking of factory reset, I need to backup my data + apps. Any one can recommend a good app for that purpose? For non-root device.

True. Just wanna ask, did you deleted insta,fb and etc that is preinstalled in the phone?
Going to try this. Thanks!
Actually, I was planning on the same thing but i'm afraid that nexus screen can't be compared to samsung although nexus amoled panel is produced by samsung. The calibration on samsung is on different level in my opinion. I've become really particular when it comes to screen after jumping ship from ip6+ to s7e. Hopefully this year nexus doesn't disappoint and also hope i've grown tired of the curved screen by then. And damn, I'm quite similar to you.. never tried using vanilla android before.

I also received the message regarding the extended warranty.

Btw, this is a Note 6 spec. Seriously, does a phone needed 6 GB ram? Lol

they just send another sms  - 'pls be informed that your s7 edge is protected with additional 1 yr warranty'
