I received my one plus 3T 128GB yesterday and I’ve been testing it. Absolutely fantastic. Those who comment on here without actually buying the phone and testing it. You don’t know what you commenting about. Go and buy one you’ll be impressed that’s for sure! .
Love this phone. I actually thought I was getting a cheaper phone, expecting to have a few problems or bugs to work out. I have had no problems with the phone, it has impressed me at every turn. The Oxygen OS is smooth, with plenty of options to customize your experience, the 6GB ram is large enough for any app, or multiple apps. I was able to save pictures and videos to a usb stick with an OTG adapter. It connects to PC and you can add and remove files as needed. Call quality is clear and the speaker is nice and loud. Music through the headset is crisp and clear and plays nearly any file available. Camera is excellent, not perfect, but with manual settings and the ability to take raw images it compensates beautifully. The price point is about 70% of a flagship device with 93% of the features. One negative, the DASH charge is proprierty, so you buy OnePlus chargers and cables, but it works awesome, a full charge from 11% to 100% in under an hour. This is definitley worth the money, it’s more than most cheap phones, but it blows everyone else away. Good luck with your purchase.
