I am a big fan of Apple. Have been using Iphone from last 5 years. Wanted to change the phone to the new one. But not much of Innovation from Apple. So, I switched to Oneplus and Oneplus 6T was a best replacement.
The OnePlus 6T brings new technology and worthwhile improvements to the table making this the best phone from OnePlus yet.
Design: Just gorgeous - the curve of the camera bump is more of a design accent than a notch. The phone has a huge 6.41 in screen, but is still easily managed with one hand. The color is amazing - Mirror Black. The 6T feels like it was meant to fit in my hand. The first party OnePlus cases accent the amazing design and make it even more comfortable. When you hold the phone, you will know exactly what I mean!

Battery: Lasts more than a day with heavy use. I can get almost 6 hrs of screen on time even after watching YouTube, gaming, and general usage. Even better, the included dash charger fills the battery extremely quickly. No wireless charging, but I don't even miss it.

Camera: Solid - 4K 60FPS video looks great. Other phones in this price range can't even touch the quality of the camera for pictures. Night shot is solid, looking forward to Future tweeks to prevent the blown out appearance when some light is present.

Sound: Probably the only change I would make. The since downward firing speaker is easy to block. The quality is great - would love to see the dual speaker in the next OnePlus phone.

While you could say that OnePlus has made some sacrifices in developing the OnePlus 6T, they all seem rather subjective. Sure it’s a slightly bigger, thicker, heavier phone than the 6 but if that means a bigger battery with better longevity is it really a loss?
The headphone jack’s absence is annoying for some but the phone comes with an adapter and the in-display fingerprint sensor might not have fit in the same footprint otherwise.

The device is very bad. Camera quality is very poor. Please don't buy it guys go for Apple iPhone XS instead. Apple has a far better Camera.

No Color options in 256gb variant. OnePlus should learn from Apple they have a lot of Color options at the time of launch. OnePlus is not worth the price.

Adding another call, when a call is already in progress is night mare. Either app crashes or it doesnt allow. During phone call disabling blue tooth is not posisble. I see lot of UI issues. God only why people were so hyped about this phone. its not doing what 7000rs Samsung phone does. Please don't buy this phone and waste your money.

I did prebook but I don't get bullet earphones

Things are not the same as promoted, I bought this on 2nd Nov, look wise its good, sound is also loud, its just loud nothin else, battery has just improved marginally if you keep your location on and play some game or video, it will be low very soon. Ofcourse at the end it will hang little longer but not as expected. Display Hangs!! Yes!!! this phone hangs even with 8gb RAM, have faced it few times even in first 10 days. Worst part is the front screen lock is too too slow, even i have to use pin code most of the time. Overall the phone launch was just a hype but the performance is not upto the expectation!!!
