The OnePlus company has faced wide criticism towards its newly announced OnePlus 5, from iPhone design similarities, benchmarks cheating allegations, camera problems and recently, the jelly scrolling effect that was reported my many users.
A recent forum post that popped on the OnePlus 5 forums pointed that in a teardown of the OnePlus 5 the display panel seems to be mounted upside down, many are also speculating that this might explain the jelly scrolling effect, while the device seems to run normally in our hands, internals show otherwise.
To back the claim, developer SultanXDA did some digging in the device's kernel and found this in the display controller code that directly shows a 180-degree orientation on everything. He also reported that this is his first time he notices this kind of a code on an actual device.
Another kernel developer from XDA eng.stk states that he also found evidence to confirm it. compared to the 3T, the OnePlus 5's display matrix is inverted, and that if we run the kernel code on a 3T, the display would be inverted.
The Jelly scrolling effect, however, is a rather odd thing to happen while scrolling, it feels like the content is stretching away as you scroll or as if there is a literal jelly motion to the content on your screen. have a look:
According to OnePlus, the illusion the screen creates when loading additional content is "natural" and might not affect all devices although there is no variance between devices, stating that all devices have the same high-quality Optic AMOLED panel.
OnePlus is yet to comment on why they went with an upside down solution, There is no manufacturing defect or software bug involved. Instead, the inversion seems to be an engineering decision done for reasons we were not given.
This problem reminds me of Samsung's old Galaxy S4 when it faced scrolling problems in low brightness, as the panel fails to light up turned off black pixels fast enough, leaving us with a purple-ich fading effect while scrolling.
It is unclear how much can be done to fix such a problem since it is purely a hardware problem, no OTA update from OnePlus can resolve it and getting your phone replaced won't guarantee you getting rid of the irritating problem.
After using my OnePlus 5 for almost two days now, I've not noticed the scrolling effect, now that they mentioned it, I can see it clearly on my screen and I can't stop noticing it. I'd be interested to see if removing that line of code in the kernel can resolve the problem (although you'd end up with an upside-down display) and I'd be interested to see if that rotation might affect GPU usage or power consumption.
