Device is awesome with zero lag. Picture quality is at its best. Reading mode is awesome for Kindle app, News paper apps etc. Battery lasts for a day at least with 3-4 hours of display usage and all time 4G on. Overall device is good.
If the cost get reduced by 3k-5k, it's THE BEST value for money smartphone.
PS: Mine is 6GB, 64GB device. I would've loved it if it had been 6GB, 128GB configuration. As I and most of the people I've known who have bought it are not high end users, and the device lacks extra memory slot, OnePlus can consider this feedback in future.

Comparing to one plus 5T , I liked the 5T better than 6 regarding screen brightness and battery back up though both one plus 5T and 6 had same battery configuration but there is a lot of difference in battery performance 5T last much longer than 6 I would say if 5T has a moderate 2o hours battery whereas one plus 6 lasts only 15 hrs. which is huge difference for same configuration, one plus 6 also does not feature fingerprint sliding gesture which is a cool feature on one plus 5T.

some feature are good in one plus 6 such as front portrait camera and hiding notch display . It is copairtively a bit faster than one plus 5t.

Picture quality of HD stream is good but other regular stream is ok
For sound you have to increase volume more than 50 % to hear clear sound , especially in hearing song or dialogue,or hearing news
Weight is also above average
Battery life is OK
Buttons given for ON/OFf are very crude should have been suffice with body
Taking into consideration above points price charge is much higher comare with other phones available in market with same specification

I have been using Iphone for a very long time. Then I thought of using android phone but was not able to choose a best phone for my self. Then one of my friend suggested me Oneplus. So I purchased Oneplus 3T and I was amazed by its performance. I have been using Oneplus 3T for almost 2 yrs then thought of upgrading to Oneplus 6. This was best decision for me. I have been using it from last 2 months now. Battery life amazing last for one and a half day on 4G. Camera superb. RAM 6GB has never let me down.

Thank you Oneplus for making such an amazing phone. One of the best phone in Android.

Back camera is not up to the mark.. pic quality is avarage..
If you zoom any pic ,it looks blurr.... Price is quite high with avarage camera quality..

Youtube is not working after Android pie update

Oneplus is at its best ???????? I've used almost all the oneplus devices and OP6 is by far one of the best after oneplus 3t. Worthy for price ( quality and performance). Back case is a must ( I use the Avengers Ironman case) which I would recommend for day to day use.

Oneplus 6 = smooth +elegant + top notch performance

It's Amazing!!! Best phone at a decent price. This is first 30k range mobile I am buying and I am in love with it.
I bought this during Diwali sale and paid 24.5k with exchange, cash back and discount.
Interface, camera quality, battery and overall performance is just wow!

Bought this Flagship smartphone from OnePlus 3 months back and here are my observations after using it for 3 months.

1. Camera is just fabulous. It works like a DSLR with the inbuilt features that are available in DSLR. It supports features like focus, aperture, ISO etc can set all those features custom as per our requirement.

2. Sound and Microphone quality is just awesome and it is audible even in crowded places. Earpiece is good to take calls with nice and clear volume ratio. Earphones are not their in box quite disappointing after paying much but you can use any 3.5 mm jack earphones of good sound quality. There is no issues found for music as well you can experince calling and music as an IOS device (Apple) supports.

3. In love with its battery backup and dash charging technology. It charges almost 60% of phone battery in just 15 mins. Battery backup is awesum as a full charge of it lasts for a full day along with heavy internet usage. Comes with 3300 mAH lithium Polymer battery.

4. Best gaming experience ever compared to all other smartphones I used to play games earlier in phones from such good brands like Nokia, Samsung, MI, and even Apple iPhone 7. You can enjoy playing high end games like PUBG one of the trending games nowadays.

5. No heating problem faced while using it for long hours with heavy apps, games and internet surfing. Its a reliable phone.

6. There are lot of trash files stored on phone's RAM which needs to be cleared time to time so that it will not cause any slowness while operating the phone.

7. It looks very classy when holding in hand as well as its outer case is very comfortable in feel & touch. Display ratio perfectly fits its design as there are no borders. Touch is vivid and highly capacitive 2.5D Corning Gorilla Glass 5 used on both the front and back so no chances of screen tempering even when there is no screenguard/tempered glass applied on display. Watching movies is very enjoyable everytime.

8. Top Notch Speed Flagship Killer comes with 8GB RAM with 256GB of Storage is enough for all heavy files and games. It supports dual nano SIM with dual standby 4G+4G which is quite good and lovable.

9. When it comes to operating system and processor it comes with Android Oreo 8.1 Oxygen with Qualcomm Snapdragon 845 Octa Core Processor which is highest available in market at this price.

10. Its face unlock features works very well when compared to iPhone X. Fingerprint sensor works fine, Water Resistant feature haven't checked as it is costly so I always avoid water from the device after even its water resistant.

11. User Interface can be improved a lil bit more for steady use to everyone and earphones can be their inside the box at this price range and a brand should manage to provide maximum accessories along with its Flagship phone atleast.

12. Overall performance is good as device works very well on all stages of usage where as while using it continuosly along with its all components at extreme levels. And its stability over the android is mindblowing.

13. Finally, I would recommend everyone to buy this device who is looking for a phone at this price range. No such phone is available in market with such high end configurations at this price range.

It is a beast. And I got this at 27k + added benefits and bonuses in the Great Indian Sale. Thankn you, Amazon, for that and for impeccable delivery of the product.

Now coming to the phone,

Camera is incredible. Great details and colours are brought out. It's crisp and at the same time not very sharp.

Notch : Seriously, I don't get why it should be a concern. I have hardly noticed it all the while. Plus, you can hide it if you want to. I have been using it without hiding.

Fingerprint : Placed at a slightly uncomfortable position. But it's ultra fast. Face unlock is also very rapid.

Speakers perform the job that they were assigned with. Got no problems, and no specialities.

Led notification is awesome. You can customize it's color.

Gesture based actions is very useful, like for pausing a song, or to open flashlight.

Overall, the phone is just pure awesome. It's nothing less than a majestic beast.

everything is perfect in this phone.. this is truely a flagship killer. battery life is great and special feature is dash charging,i love dash charging of one plus you don't have to take stress about the battery just connect it for half an hour and you're good to go. sounds quality is decent. picture quality is awesome,it comes with amoled panel what else do you want in a phone at this rate ( a true flagship killer) or i call it legend killer
