    Tex99 , Nov 29, 2019 :
    Slight stutter when flick scrolling on both 60hz and 90hz and light theme on the following devices:

    - Oneplus 7T frosted silver OOS 10.0.6: lag on scroll with a glitchy transictions of written lines is PRESENT

    - Oneplus 7T frosted silver OOS 10.0.1: lag on scroll with a glitchy transictions of written lines is PRESENT

    - Oneplus 7T glacier blu OOS 10.0.1: lag on scroll with a glitchy transictions of written lines is PRESENT

    - Oneplus 7T PRO OOS 10: lag on scroll with a glitchy transictions of written lines is PRESENT (but harder to see because of a strange acceleration on scrolling)

    - Oneplus 7 PRO OOS 9 and Oneplus 6T with OOS 9: this issue is NOT PRESENT

    When I scroll I notice that some lines of words on display don't do a fluid transiction, but they "disappears-appears". You can notice that issue when you do a quick scroll with finger (and you don't keep the finger on display), just open settings app (light theme) and do up down.
    It happens with settings, Chrome etc.. it s not an app related problem but probably to android 10.

    Btw the right title for this thread Is "Stuttering (frame drop) transiction of the text while scrolling"

    I made a video that takes up the issue and shows how to reproduce, even if the camera cannot capture it well (hard to record 60fps), it is drastically more evident live, trust me (I recommend to look at the written text at the center of the screen to notice it, while I scroll down, because they appear some "lines" during text transiction, it's not smooth at all).

    LINK (it's better to download for quality and watch it on bigger screen, open with chrome): https://gofile.io/?c=dGaFtF

    Hope that you can see the issue, I know it's not so visible on video but I don't have a professional camera

    Of course the issue is still not fixed with 10.0.7 EU.
    I'm trying to chill but this device costs 600 bucks and I never saw this issue on any smartphone, that's a shame and a totally waste of time and money. Tested other two 7T in an other shop and same issues.
    It's not possible to ignore it, you always look at the screen.
    Oneplus did a terrible job with android 10 or they used a cheap display with some touch/scrolling issue, that's not accettable.

    I found other people on xda with the same issue around the world, so it is not region specific.

    Of course no reply from staff in pm or in my feedback post (
    https://forums.oneplus.com/threads/lag-scroll-android-10-bug-on-7t-series.1146895/)

    In addiction there are over 10 feedback of other oneplus devices with the same issues, that's really a shame, this is the worst experience with a smartphone

    Hi there. This is happening on my 7T 8/256 HD1900 Frosted Silver Model as well. Running 10.0.7

    And I though I was the only one. :(

    When I bought my unit around November, I think it was running 10.0.5 or .4, so that's 2-3 updates already without any fix.

    You think it's hardware related?

    hi, I tested over seven devices and all have this issue. It 's present on all 7t in my opinion but it seems that not all people see it. I had to do another feedback because it's still present on 10.0.7, please leave a comment/like/upvoted here : https://forums.oneplus.com/threads/...le-scrolling-oxygen-10-bug-on-all-7t.1171252/

    you can also report your experience in the thread: https://forums.oneplus.com/threads/...g-oxygen-10-bug-on-all-7t-7tpro-7pro.1148402/

    Thank you very much

    I just bought One Plus 7t pro in India. I am facing the same issue while reading & scrolling. It is quite annoying and noticeable. Is it hardware issue or software issue ? Otherwise I have to replace my product.
