Missed taps on S24 Ultra

[Sathir]

Missing touches very frequently, and it's very disturbing. Sometimes clicking while scrolling. While scrolling, accidental touch happen. All I do is scrolling. This happens regularly. Bought this mobile just two or three weeks ago. I'm noticing this from the beginning, and I thought I'm not used to the device, but it was an issue.

Even that is OK

[Sathir]

There were 24 tests to be done I went through all except chargers and usb. They seems little odd my finger was going right above those 50 tiles to fill also I can see small circle following my finger movement, but the tile not changed to blue, then started to work second time. I feel it's the issue.

Did the issue fix? Or is it still there?

[Sathir]

Issue still there, I'm experiencing this lagging, especially while scrolling either horizontally or vertically. First few scrolls are okay but if I increase the speed and combine vertical and horizontal scroll then everything started to gost touch missing scroll and I can quickly understand this is not smooth and missed a scrolling spot.

This is on 120Hz adaptive refresh rate?

[Sathir]

Yes in 120, I have enabled refresh rate from developer option so I can see that in the corner, and its fixated on 120 Hz. While doing the above mentioned things there's a sudden drop to 24Hz for a millisecond, that's where the touch is being miss calculated. This week, I'm planning to meet one of my friends using the same phone S24 Ultra, and do the side by side comparison with the touch sensitivity and will update on this matter. For the moment I don't have much detailed findings to escalate this.

Do u use an app called Galaxy Max Hz?

[Sathir]

I was using this.

[Dr_Sadesh_Abey]

Yes but are u using Galaxy Max Hz? Or a different refresh rate limiting app?

If your refresh rate dips to 24Hz that's why the lag appears. Usually when using 120Hz refresh rate, the phone dips to 60hz when not in use to save power and ramps back up to 120Hz when touched. If your phone drops all the way down to 24Hz, then there is an app that is controlling it and making it drop to that level. If u can find the app or the setting, you can get ur screen back to the normal refresh rate

[Sathir]

No any apps to control my refresh rate actually, I was using just Facebook scrolling and felt the lag and started digging on this issue. Then figured out after doing faster scrolling I mean one swipe and between another swipe milli second time this refresh rate drops to 24 Hz all the way from 120 Hz. I don't think we can have a workaround to fix this, could be a firmware level patch.
