Its not the hardware that sucks. It's OxygenOS. OnePlus One sold so well because of CyanogenMod. And look what's happened when their joint-venture fell apart. It simply wasnt up to par with the rest of the flagships. Go online and read about the crappiness of OxygenOS and you'd find out what I mean. Apps take 10 billion years to launch on OxygenOS launcher, camera lag is real. and battery life wasn't all that good either. I only had this phone for a few days before it was stolen from me lol.

i do to have agree with u, but things getting better and better with oxygen OS.. a lot of improvement since being updated to android 6.0
