Good phone as far as I can compare with Okitel K6000 PRO
Advantages: Very fast - really snappy operations
Really good camera with Optical Focus STabilization!
Good display, not the best but really nice
64GB rom - fast storage, better than battery draining SD cards in my opinion
Good phone reception and good quality of the sound and speakers
Overall design and feel is really good
REALLY CHEAP for a old but still very fast PHONE
Limitations: OLD hardware - for the price you can't get better *original hardware of OnePlus One*
No SD card - I personally like this as I never bother to install battery draining SD cards, instead you have large and really fast 64gb internal rom
NO Android 7 official update - I like Cyonogen Mod 12.1 based on android 5.1.1 and everything is working nice but it would be great to have the latest
Phone gets hot on the metal bazel while playing games, not noticable if it is inside soft case
