Jelly scrolling effect spotted on the Moto Z2 Force
The OnePlus 5 was released towards the tail end of June and, within the following weeks, was associated with a host of shenanigans that did not help the phone's publicity and marketing endeavors. One of those was the jelly scrolling effect that was spotted by the good folks over at XDA, an effect that was caused by the phone having its display inverted. You can have a closer look at what happened here.
The Z2 Force was released a few weeks ago and fans of the OEM were quick to express displeasure on the overall outlook of the device. The Z2 Force, following the recent trend, ditched a 3.5mm headphone jack and went even further by reducing the battery capacity on the phone. The same device has been spotted with the jelly scrolling effect, and we're beginning to ponder the thought processes behind inverting display panels.
Displays usually refresh from top to bottom, a phenomenon which is visible but only when actively sought after, as the human eye already tends to scan from top to bottom. Having the display inverted means it refreshes from bottom to top, and causes the supposed "Jelly Effect", an effect more observable in this case as the refresh path is in the opposite direction to our eye motion.
Daniel Marchena, the XDA user who discovered the effect, has claimed that several other Motorola devices have the issue. That's no surprise, really, as the effect is such a minor issue that your eyes get used to it in weeks.
Here's a video of the jelly effect on the Moto Z2 Force.
