Atomic , via OnePlus 5T , Jul 13, 2020 : Hi, I just want to say that I have been a oneplus customer since the oneplus one. If there is one thing that made this company stand out it will have to be the software. Although I am happy to see Android 10 land on my beloved 5T, I can clearly see how it was not optimized well enough before being pushed out to 5T devices. Here are some of the bugs I am facing and I hope you take it into consideration. 1) The battery. On Android 9 my 5T was a powerhouse, I keep NFC, BT, GPS, Data, Wifi on all the time and I use my phone for everything from NFC payments to GPS navigation to online browsing and even watching youtube. I used to get more than 6 hours SOT comfortably. After the update, I barely get 4 hours. This is honestly the worst thing about the update. I don't want to perform a factory reset because of all the apps I am using, that's the main reason I don't like to change phones often. I don't want to go through the set up process again which I believe is a valid point. I only wish that oneplus fixes this issue in the next incremental update. Sadly there is no way to revert to A9 while keeping your apps so now I am stuck waiting. 2) Google Chrome crashes ALOT. You have to go back home and reopen chrome to fix the crash. It is not ideal. 3) Although this was mentioned in the update, but the lack of EIS is clearly visible in the videos you take and it has made the camera mediocre. Now I feel it's not worth it to take a video. I also don't want to waste more battery. 4) the animation of the screen rotation in YouTube is very slow in comparison to A9. It affects the experience and makes the phone feel cheap. Other than that, the A10 update seems cleaner than A9 and better organized in a sense. But If I had the option to revert without losing my apps (going back in time is the only way I guess) I would definitely do it. I wish I didn't update and waited for the next update but honestly to give credit to oneplus, I have never faced such issues on any of their updates. I always got the best experience when I updated. Oneplus please fix these issues :-( I am planning to keep using my phone for atleast 1 to 2 more years and with this battery life its impossible :-( If anyone has any advice please let me know (I won't factory reset or root my device though) Thanks!
