As i've been using this ohine since 3 months. I find some lags in opening the gallery and msgs. The LTE network is also kinda good. But looses network a lott and yes one plus company is working on the update and that will come in later december. Audio in headphone is pretty flat. Loudspeak is kinda okay not awesome though due to only one speaker. Front camera is good with 8 Mp and back camera with 16 MP with 4K recording. Audio recoding is pretty poor in one plus models. Speed of phone is pretty awesome but some app may lag in it. BEST THING ABOUT ONE PLUS 3 IS DASH CHARGING.
CHARGES MY PHONE IN 35 MINS FROM 0% -90% BATTERY. 4AMP OUTPUT FROM DASH CHARGER. BEST WHILE TRAVELLING.
