OnePlus mobile owners have a principle. When you are a OnePlus owner, you never change owner again. I recently switched from OnePlus 2 to OnePlus 6t 8gb/128.
Let me start. The phone not only worth its money, but I feel like we are actually stealing from them.. a phone that costs 550 euros outperforms the galaxy s9, after all it rightfully won the award for Top smartphone of 2018. Camera quality? Amazing and incredibly realistic. As for recording in 4k 60fps, I was just pulling my hair and saying it can't be, it can't be so perfect. As for the fingerprint, those who mentioned that it doesn't work or is slow or I don't know what, are probably haters :D because it works flawlessly with a 99% success rate and without any issues, the face unlock is really fast that you can't even understand what's happening, and of course it's reliable, even in the dark and from a distance of half a meter. The phone is a demon! Pretty powerful speaker and high-quality sound recording. Wonderful software with the help of oxygenos of course, and let's talk about the battery. I really try to go below 25% and I can't. The fast charger makes sure to reach 100% in half an hour with 4A. That's it from me, also the mirror black is perfect, you can even shave with it although it gets dirty quite easily due to its surface.

19/8/19 UPDATE**
Today I accidentally took the phone out of its case to clean it and I see the back cover is broken. Obviously, the case was unacceptable for this and ---- NEVER SPIGEN CASE ---- Don't prefer it!

I am the owner of this mobile phone since its release day.
In terms of hardware, the phone is top-notch: SD 845 with 8GB RAM = incredible speed in all apps/games.
The only areas where it falls behind compared to phones that cost 800+ euros are:
- the speaker, which is just average (although it's okay in terms of volume)
- the camera, which is indeed a pretty good camera but falls short compared to the other flagship phones from Samsung, Huawei, Google, and Apple.
Of course, none of the above-mentioned companies offer a flagship phone at this price, and with the Google Cam APK, the difference is even smaller ;).

However, the best part of the phone for me is the software.
It's almost stock Android, with the only differences being some settings and some nice features that OnePlus adds to its operating system. Generally, these are only changes that make sense and offer something extra to the user, rather than useless apps that you can't remove.
Aesthetically, the phone has perhaps the most beautiful (and smaller) notch that could be made.
Unfortunately, to have this notch, the notification LED was sacrificed, which can be important for many people.
Personally, I'm not bothered by the lack of an audio jack since there are countless affordable options for Bluetooth headphones nowadays.

Overall, it is one of the best smartphones of 2018 and at a very good price for what it offers!

Guys, I know that you will all vote negatively, but I will share my opinion about this device and my purpose is for you to read this before wasting 600€ on the oneplus 6t... As we all know, oneplus produces phones that are value for money as it competes with all the 1000€ phones and costs 600€. Yes, it is very fast and for me, it is one of the fastest android phones. However, I was disappointed with the oneplus 6t after about 3 months of use, not because it started lagging (it still doesn't lag, fortunately), but because unfortunately I realized that its positives are only the speed and the oxygen os, which is very lightweight compared to other android software but it is not smooth and premium at all... Nowadays, all high-end phones have more or less good features (e.g. snapdragon 845/855, exynos 9820, kirin 980, a12 bionic, many megapixels, etc.) and their user experience is not like that of mid-range phones. You won't find a phone over 600€ that is not fast and doesn't take very good photos. The issue is the details. In order for a high-end phone to be considered value for money, it should be very smooth, have high-quality and expensive materials, its manufacturers should pay attention to every detail, not spend little time on the design internally and externally, and generally not be rushed. Additionally, the software and the phone internally should be worthy of its high price, have stereo and good quality speakers, a qhd+ display, a good battery, and be durable (we are in 2019). Furthermore, the camera should not only rely on megapixels but be well-developed, have good stabilization and dynamic range, good camera resolution but in combination with many fps, and mainly reproduce realistic colors. Unfortunately, I didn't find these in the oneplus 6t, which in my opinion should not be considered a high-end phone and compared to phones like mate 20 pro, p30 pro, galaxy s10+, and especially iPhone XS Max... I hope my review helped you and that you understand it!!!

P.S.: I come from an iPhone X, so I have the comparison in mind of a high-end phone with the oneplus 6t!!! Also, I believe that it is not worth the money at all because its price has not decreased since its release and now for the same amount of money, you can get either the iPhone XR or the galaxy s10/s10e!!! Additionally, I have noticed that for the first time, a phone tires me in such a short period of time and its sar index is one of the worst/highest in the market and I should note that its ram is simply the worst ram in a phone (there is a website called dontkillmyapp that lists the 10 worst rams of all smartphones and oneplus is second after nokia...) I paid for 8gb ram for nothing. I really don't know how the pocophone f1 falls behind...!!

I am the owner of this particular phone since the day it was released. I was a long-time Android user and one day I decided to buy the iPhone 7... After a lot of use, I decided to go back to Android because I missed the customizable software that Android offered, so I bought the OnePlus 6T (big mistake)... Well, I mainly use the phone for social media, camera, gaming, calls, etc. This device has some positives, but the negatives outweigh them... Let's start with the positives... Firstly, it is quite fast, charges very quickly, and the battery lasts for a day and a half with heavy usage. Now, the negatives... let's start with the external aspects of the device. The glass of the device, as OnePlus claims, is Gorilla Glass 6, which is supposed to be very durable, but that is not the case at all... The phone got a deep scratch in the first week, which I find unacceptable because I had put an authentic OnePlus case (expensive) on it, which supposedly provides great protection, and I never left it on the table with the screen facing down, and I generally took care of it like my own eyes... The glass feels very cheap for some reason, and overall, the phone is very bulky with no indication of a premium texture (unlike other flagship phones). It is also very heavy, and holding it feels like holding a brick... Now let's talk about the internal aspects of the device... The phone is really only fast and nothing else. Especially the 8GB of RAM it had was useless because after some time when the apps were in the background, the phone would close them on its own (unacceptable)... The camera is quite mediocre and definitely does not reach the level of Apple, Huawei, Google, etc... The highly acclaimed Oxygen OS is indeed very customizable but not smooth at all, and it lacks many details to be a premium and smooth software (I really missed the experience that Apple offered me with its smoother and simpler software)... Now the screen quality is UNACCEPTABLE. It is the cheapest OLED screen I have ever seen in my life and is far from the quality of Samsung screens... Now let's talk about the in-display fingerprint sensor... it is really the worst I have ever seen as it unlocked with my brother's fingerprint, which I hadn't even placed on the device before (which makes it very insecure)... Also, the unlocking process becomes slower over time... Now the speakers... although they are quite loud, they are not of good quality at all. Also, the scrolling is by far the worst I have seen on a phone... Finally, I would not recommend this phone to anyone as I regret the 600€ I spent to acquire it... (the phone is really worth around 200€). I truly hope I helped you so that you don't make the same mistake as I did!

First of all, I have been a owner of the oneplus 6t since the day it was released. I mainly use it for social media, photos-videos, gaming, calls, etc. Let's start with the positives of this device: Firstly, it is a fast phone, secondly its software is truly the most customizable and doesn't tire you with useless things compared to Samsung (personally, I believe it is one of the best, if not the best, Android software). Thirdly, its battery charges very quickly (up to 1 hour and 25 minutes!) and lasts about 1.5 days with heavy usage. Now, the negatives of the oneplus 6t... Firstly, it looks like a Chinese - not a quality build and appearance... Secondly, its camera is very similar to Samsung, meaning that although it has good resolution due to the high number of megapixels, the colors are very overexposed and overly bright (especially in 4k video) and it doesn't reproduce realistic colors. Thirdly, the screen resolution is not at all high quality (one of the worst OLEDs) and it is not at all durable (even though it has gorilla glass 6...) it got scratched deeply from the first week even though it had a case and I never left it with the screen exposed. Fourthly, it is not at all smooth and the scrolling is perhaps the worst I have seen on a phone! Fifthly, I can't not mention the in-display fingerprint sensor. It works most of the time but you always have to place your finger exactly in the "right" area and it is still very slow and sometimes unlocks with my left finger. Let's not even talk about the face unlock which never works with glasses... Also, the headphone jack is greatly missed and it now costs 600++€ (and it's supposed to be never settle and cheap...). The speakers, although quite loud, are not at all high quality. Furthermore, it is not at all good for gaming considering its price, it has low fps, unsatisfactory graphics and generally struggles with very large games. It is very large and difficult to use with one hand, it is very heavy, somewhat thick and not at all sturdy. Finally, personally, I regretted spending 600€ on the oneplus 6t. It is day and night compared to the iPhone XS Max, Mate 20 Pro, P30 Pro, Galaxy S10, Note 9, Google Pixel 3 XL. I would not buy oneplus again, especially now that they have become and will become very expensive and their price does not decrease. I hope I helped you!!!

P.S.: I should note that now the battery doesn't last a day with heavy usage.

2 words only. The phone. Great screen, battery that lasts all day and works all day with heavy usage and still lasts and lasts and lasts. What's the point of wireless charging when it takes 1 hour from 5% to 95%? Type-C port and for music. Fantastic connectivity, fantastic GPS. Speaker, even though there's only one, is powerful and has very good sound quality. And the best for last. Thunder Purple looks amazing in color, and then Midnight Black. Very good construction. Cameras are among the best, with the only weakness I found in zoomed photos. As for videos in 4k 60fps, crystal clear and top-notch optical stabilization. Finally, speed. And the fingerprint is very fast, but in face unlock, you can't even tell what happened and when it unlocked. As for the 845 processor, it handles games non-stop, it shuts down all of them when the temperature goes above 35 degrees, even with hours of gaming, it just handles it effortlessly. Get it with whatever you want... if you have 570 for the 8GB 128GB version, get it now...

I have had the phone for about a month now and after using it in my hands, it's time to write some positives and negatives.
But before that, I want to mention that I compared it with the new Samsung Galaxy S10+ (I gave it a tough challenge but...)

Positives: The phone is literally flying and I really can't find anything faster out there, even if it's worth €1000.
The screen is truly one of the best in terms of resolution, and the differences with the flagship models of Samsung, Huawei, etc. are very small.
It has the best touch sensitivity I have encountered on a phone and the fastest fingerprint unlock (I say this because now on all flagship models, the fingerprint sensor has been moved under the screen).
The fast charging is truly unbeatable, I mean Huawei's effort is good but OnePlus continues to outshine them in this area.
The feel and ease in the hand are something else, really.
The phone's photos stand next to other expensive devices and of course, I can't ignore the fact that the quality-price ratio is the best with this phone.

Negatives: It's not possible to have a phone with glass on the back and not have wireless charging.
Also, I am disappointed that it doesn't have stereo speakers.
Lastly, I believe the design could be a little better, the discreet teardrop on the top side is nice but the screen could have better curves.

Overall, there is nothing better in the price range of €500-€600.
I didn't mention the absence of the audio jack because anyone who buys the OnePlus 6T would find it unthinkable not to get the Bluetooth bullets, which, once you experience the sound quality, you'll simply be amazed.

This mobile phone is the best value for money option on the market right now, considering that all flagship phones are priced at $800 and above, while this one is available from the official retailer for $550 (which is not considered cheap by any means). However, when it offers literally the same or even more features than its competitors, you know that OnePlus is doing something very well. The best feature for me is that for the first time, there is an Android phone with software smoothness comparable to the iPhone. Not that other Android phones are not fast, but they can be a bit clunky and laggy in multitasking, scrolling, or switching between two apps, for example. And I say this coming from a Nexus 6P running stock Android, which, by the way, is not as fast as advertised, as it crashed on me several times to the point where I couldn't even restart it. On the other hand, OnePlus with Oxygen OS, which is a slightly customized version of stock Android with small tweaks that actually help a lot, managed to have the best software on a mobile phone right now. Of course, we still have to see how it will perform over time. The only "negative" thing about the software is that it will receive updates for up to the next 2 years, which I don't understand, considering its great specs and seeing that Apple supports its phones for up to 5 years. It has all the essential features without being filled with extra apps that are never used, like Samsung does, which eventually causes bloatware problems. The settings offer a plethora of options, with the most important one for me being the ability to use gestures instead of the classic 3 buttons at the bottom of the screen, which I found very convenient and with very fast response times. For unlocking the phone, you can use the fingerprint sensor located below the screen, but it's not as fast as the traditional ones and it depends a lot on the finger placement. Sometimes it unlocks instantly, and other times it takes at least a second, which is quite a long time when you're used to a fast phone. However, this is something that can be improved with future software updates. As for the face recognition, it is ridiculously fast to the point where you don't even have time to see the lock screen, making the fingerprint scanner practically useless during the day. It also works regardless of the phone's orientation. It doesn't use 3D mapping like the iPhone, but still, it's practically foolproof. The camera is quite good, but it doesn't compete with the cameras of other flagship phones like the Pixel 3XL, Galaxy S9, and iPhone XS. The notch is the best implementation on a phone right now, being so discreet and small. There is an option to hide it in the settings, but in my opinion, it's not necessary because you get used to it after a while. The screen is huge with very nice colors, and combined with the fact that it's an AMOLED display with a resolution of 1080p, it greatly helps with battery life. There have been many discussions about the choice of this resolution instead of, for example, QHD, but let's not fool ourselves, practically the difference is negligible to the naked eye, unless of course, you hold the phone 3 centimeters away from your eyes. The battery life is extremely long to the point where you forget to charge it, at least for now, in the beginning. As an example, I watched a one-hour episode and the battery only dropped by 3%. The box includes a dash charger (which is a technology of 1+) that I timed and gives 55% in 30 minutes. One negative aspect is the large aspect ratio, which is problematic in some applications, such as Instagram, where it hides a small percentage of the image in stories. For example, if someone has written something, the first and last letter may not be visible. Also, many people are bothered by the absence of a headphone jack, unless you need to use both the charger and the headphones, then it is not a problem. Let's not kid ourselves, the industry is heading towards the total elimination of this specific port because everything is now done wirelessly. There is no wireless charging, which I personally find neutral and useless given the huge (3700mAh) battery and dash charging. Finally, the large RAM helps you return to an application at night that you opened in the morning and find it at the point where you left it, which I find extreme considering that most phones simply reopen the application and you have lost what you did. However, if you are going to get the 8GB model just for the extra 2GB of RAM, don't do it because there is no substantial difference. If you have a specific preference for color and texture (glass/metal), then yes, it is worth it.

After 2 and a half months of living with this phone, it's finally time for me to write an objective review... Very nice phone with a nice feel in the hand, in my opinion very nice design as well. Very good software (with a few minor issues that I will mention shortly), it doesn't lag at all during browsing or gaming, and I play heavy games of our time. The screen is very good, the battery is decent, and the camera is something that I personally really liked, coming from the Xiaomi Note 4 (night and day difference). I can't speak for other flagships because I haven't owned any, but I'm almost certain that besides the camera and maybe the screen, it has nothing to envy. I use the phone a lot due to my work, WiFi or data all day, lots of GPS, many phone calls, a fair amount of browsing, and very few photos. With all of the above, my battery lasts almost two full days, which I have never achieved before on any of my devices without battery saving. As for the software I mentioned earlier, it has some issues that I don't know if they exist on all devices, but I will mention them so you can have an idea. Messenger crashes, and it's not the app's fault because I don't have any issues on my other phone. And sometimes the double tap Wake/sleep doesn't respond. I contacted OnePlus with their very good customer service and we concluded that I should do a full reset of the device to fix it. I haven't done it yet because it's a minor issue that I don't want to deal with extensively, I just mention it because I noticed it. So, the verdict:

Battery - 5/5
Screen - 4/5
Software - 4/5
Camera - 5/5
Aesthetics - 5/5

Is it worth buying compared to the flagship phones that cost 1000+ euros? 100% value for money and you'll annoy them with the super powerful Chinese phone that costs half the price... I, of course, bought it from the official OnePlus website for 570 euros since at that time they were selling it cheaper than anyone else!! I hope I helped anyone who is considering buying it or has any doubts.
