When it comes to debuting innovative products, the initial release often faces close scrutiny, particularly in non-traditional domains such as foldable smartphones. OnePlus, known for pushing boundaries, entered this arena, surprising many skeptics with a device that some argue surpasses competitors like Samsung and Google. Despite this, the OnePlus Open encounters occasional challenges, with a notable concern being the touch response delay on the outer edge of its screen.
Users experiencing this issue report being able to replicate the input delay by tapping and holding near the screen’s edge. Further investigation by some users involved in-depth debugging, revealing that these delays persist even when the floating keyboard is enabled.
With the phone closed and in portrait mode, open the keyboard. Tap the letter “p” immediately followed by “s”. Do it super fast with no pause in between taps. Try to tap the rightmost half of the “p” button near the screen edge. I’m seeing a touch lag on the “p” press and it actually prints “sp” despite the fact that I typed “ps”.
I also tried this on the opposite side of the screen. I did the same test by tapping “q” immediately followed by “k”. If I tap the leftmost half of the “q” button (near the screen edge), the touch input lags and I get “kq” instead of “qk”.
Interestingly, the problem extends to the Oppo Find N3 Fold, sharing the same specifications as its OnePlus counterpart. Reports of a similar issue date back to the OnePlus 8 series, raising questions about its persistence across different models.
The likely culprit behind this touchscreen delay appears to be OnePlus’s aggressive palm rejection algorithm. This leads to a crucial question: is there a solution? Let’s delve into that.
To alleviate the impact of the touchscreen delay on the outer edge of the OnePlus Open, some users have successfully implemented the following workarounds:
- Enable “Mistouch prevention” within the Keyboard and Input Method settings.
- Enable “Mistouch prevention + Sensitivity to back gesture” under System Navigation.
Try applying these tweaks and observe if they mitigate the touch response delay. It’s important to note that, as of now, the official stance from developers does not acknowledge this issue, and there is no provided ETA for a fix. In the absence of official updates, these workarounds stand as the most effective measures. This guide will be promptly updated should there be any official acknowledgment or a fix rollout. In the interim, consider employing the mentioned workarounds for the best possible resolution.
