I am toxicologically academic with mobile research and after a hundred videos and reviews, I decided to go for onePlus instead of RealMe GT neo. I am not a gadget enthusiast nor do I know everything about specs. After one month of use, I will briefly say the following:
Pros:
It came with a pre-applied screen protector. I really liked the design and it feels elegant and of course very fast. I got it for its software and I can say that I really liked it. Watch videos to see how the settings, layout, and colors look to get an idea. The camera is decent, I don't deal with it extensively, but it is definitely in the medium-high category. The sound is very good for both calls and YouTube, etc. Of course, it has super-fast charging with the 65W charger, but if you care about battery life like me, then I try not to always charge it from there. When charging from another source, it does have a strange pause around 75% and slows down, I don't know if it's intentional for battery life improvement.
Cons:
I was disappointed that there is no notification LED to know, for example, if you have a message, apart from a brief lighting on the right and left of the screen, but it's momentary and not prolonged. (There is an option through apps, but it consumes a lot of battery). Sometimes during a call, the proximity sensor gets confused and mutes the call. The screen doesn't look very good in the sun if you have brightness set at 50% or higher, and you have to increase it.
The most serious issue for me is the excessive temperature rise during operation. I don't know if it's because of the summer, I would like anyone with experience to enlighten me.
Overall, it is quite value for money and I recommend it for mid-range.
*UPDATE*
I sold it and got the RealMe GT Neo 2, which is 1-2 classes superior to the Oneplus. If you want a better camera, stick with the Nord 2
