I posted this on a query of which phone to purchase : LG V10, Nexus 6P or Xperia Z5
I am only getting my Xperia Z5 Premium next week - so no comments yet on this phone

Between the Nexus 6P and LG V10 - my choice is LG V10
Different users has different needs . So to decide which phone is "better" will solely depend on which phone features are important
I had never believe in any phone being the best
Simple summary between Nexus 6P and LG V10 - hope this will help forumer fruitie in her decision

Nexus 6P : Good for its fast firmware updates, very smooth phone, lots of roms flashability. Has best camera of all Nexus I had ever used ( except Nexus 5 which I had no experience at all). The camera can stand proudly amongst the Note 5, LG G4, V10 though personally I rate its camera still poorer vs them. Some people like its display ( Amoled) though it doesn't appeal to me as I had never like Amoled all this while. Phone performance and multi tasking is good though not excellent. USB OTG on this phone is slight tricky - it could easily detect both thumb drivs ( 64GB) and Sandisk dual thumb drives ( 64GB) BUT ES File explorer app, solid explorer app can only read the thumb drives BUT not the SD dual thumb drives. I needed to install a paid app USB OTG File explorer app to do this to be able to manage files between the SD dual thumb drives and the phone

LG V10 : Inits default UI, its smoothness loses to the Nexus 6P. But with Nova UI installed it can now easily match N6P.
Performance can easily match N6P even though it is a lower 808 chipset. USB OTG works flawlessly out of the box. The camera is obviously much superior vs N6P. Performance is quite similar to N6P. However I had faced a strange issue with MX Player Pro on the N6P - it always takes 5-6 sec to display the full list of my 20 GB video collection while it is close to instant on my LG V10 ( same set of files on ext SDCard)
The other advantages of the lG V10 are its removable battery cum ext sdcard support. Some users claim the secondary display as unique but I don't like it all and just a gimmick to me
Build quality I prefer the LG V10 as it is more masculine vs the more feminine N6P !! Design wise the N6P wins !
Battery wise ( based solely on 80% internet based usage with no gaming) : the N6P I could easily get 5-6 hours SOT vs 4-5 hours SOT on the LG V10. I had never bother to use any apps to tweak to assist battery usage. DOZE works fantastically well on the N6P with battery hardly drain even with phone standby on over several hours !!

My Nexus 6 was the WORST experience in quality I had bought for the last 1 year+
After 2 weeks the back cover came loose and there was an obvious gap. I suspect it was due to the quick charging weakening the double sealed tape. The phone does heat up significantly while under charge.
I put in a very short complaint ( as given only a very small box to input) on Amazon France website . Was thoroughly happy that they responded within an hour and said they will send me a new replacement unit. I didn't even need to post any photos or elaborate further. The phone was UNBELIEVABLY air out within 4 hours I lodge the complaint and it reached KLIA on day 2 !! I had to courier back the defective phone within 30 days
After a month pass on the new phone, the camera focus failed. This time Amazon said since past 30 days NO replacement will be made but they will refund me FULLY all my purchased costs including courier return charges. I got the refund in 2 weeks

I had never need to worry about doze
It had always work magnificently well without any battery tweaks
We cannot access n tweaked doze yet
It had been.very good on all the custom roms I had tested to date ( chroma, noob, aosip n photon)
I had never even bother to check what background app are on

Finally I managed to flash successfully a CM based rom - Candy6
My previous attempts on CM13 n Temasik CM always ended up stuck at Google logo
The bootup time is very fast
Initially I thought it hung as signage setting cm storage settings stay unmoved for about a minute
Now exploring the rom

No such issue on mine. Even on maximum volume I don't even hear any distortion. It is indeed very loud !!
