Ghost Touch on a Specific Vertical Line of the Screen.

Hello. I have been having ghost touches on a specific x-axis line on the left side of the screen. I know this because the tap overlay sometimes skips, is not smooth on certain parts of the screen, and clicks random menus for no reason.

I have tried removing my screen protector, resetting all settings, turned touch sensitivity on and off, and clear cache. Alongside turning the tablet on and off, the issue seems to be gone. However, it does come back at random times (especially while charging). I'm would like to know if this is something hardware related before disassembling it for visual inspection.

Thanks for your help!

Figure 3: Tab seems to go erratic whenever the edge/bezels gets touched by the case.

@albertlover839 any Ghost touch will always be originating at the display assembly since it is a touch screen issue. You most likely will need to replace the display assembly. These are definitely not cheap [关联产品丢失或禁用: IF252-063]. This is a relatively new device and I most certainly would check with Samsung etc. to see if this does not fall under some kind of warranty repair.

is it purely and lcd screen problem or the whole thing?

@albertlover839 since it is pretty much the same area at all times it will be an issue with the touchscreen. Reset etc. did not resolve that also pretty much rules out a software issue. I would not disassemble until verified that this is not a warranty situation.

Looking around the edges of the tablet, there seems to be a very tiny opening between the screen and the internal structure. Last time this was opened was for replacing the USB C four months ago by a third party shop recommended by the offical store people of Samsung (but that was a long time ago and this only happened recently.)

Alright, I have doubts for warranty since this thing has been opened long ago.

I'll have the screen reglued at a local 3rd party repair shop in my town that seems trusted and knows what they are doing based on their FB page.
