I am writing here because I am desperate in succeeding to find any attention from Samsung about a problem which destroys UX on Samsung DeX that firstly presented itself in Android Pie, extended to Android 10 and survived many patches including the recent ones.
I am on Samsung tablet (Galaxy Tab S4), but also the newer tabs are affected. So we are speaking of Samsung DeX for Tablets here. The current version is 3.7.02.1, but it manifested down to 2.5.x.x; it occurs too iften to ignore it and basically it ruins my User Expierence.
Over 2 years of using my device I created at least dozen cases in my regional Samsung Tech Support; submitted dozens of case reports in Samsung Members, many were very accurate and detailed, with logs attached. Also I submit every time it occurs with a short description and logs attached, and this makes hundreds of reports. Even while writing this text (up to this moment) it occurred twice!
I have no idea why these reports never reaches Samsung DeX developer teams, obviously something is broken with Samsung services or Samsung decided to ignore the problem. So I write here for a small chance that the actual guys working on Samsung DeX will notice this and fix it, or spread the word until it reach the proper guys. If you can do that, please help and spread this among your contacts. The support years are ending soon for my tablet and this critical bug still NOT solved, so there is a big chance to be left with a buggy d3vice on my hands after all the years and this s…cks.
SystemUI process on Samsung DeX seems to stop receiving events, its buffers overwhelm ans it crashes with a message box “SystemUI process stopped responding, Wait, Close, Submit Error report”.
This may happen first time anywhere from dozen of minutes till days of using with typical values of an hour; more often it happens when entering text into boxes, unlocking device, and opening notifications and general interaction with items placed on TaskBar (even simply scrolling icons of open apps left and right).
Interaction first becomes laggy with microfreezes, and very soon they become noticeable and finally all becomes non responsive. Most often this limits to the elements on TaskBar and TaskBar itself, while the other apps currently open not affected (I can interact). But about 25% of cases it also spreads itself to every open app, so I cannot interact. Several times it required force rebooting to recover, twice or thrice it rebooted on itself without asking me.
After rebooting (the buffers are refreshed and empty) there seems no evidence of the bug! Until it first appears, and when it does, it repeats really often - often enough not to allow for any meaningful working!
This whole situation result in too often reboots and hence, inability to sustain a stable workspace with open docs, apps, etc. , rendering the whole idea of Samsung DeX useless.
Now I have to admit, I have many apps installed so since there are more elements added to the TaskBar and more notification events than a normal User might have, the buffers overwhelms too fast for this bug to manifest in reasonable time. Maybe Samsung tagged this bug as “not important” after not being able to reproduce it on minimal configuration (no apps installed) but this is natural as minimal configuration produces least number of events so there is nothing to overwhelm!
My device though, never runs in low memory conditions, it is 256Gb/6Gb model, so typically I have 1 - 1,5 gigs if free memory (2,2 just after reboot).
My Samsung account is email@example.com - in case the proper guys are reading this, you may check the cases submitted and logs attached to this ID.
On your request I can do more logs.
Thank you everybody who read this and is able to help.
P.S.: what is NOT helpful, are the advices to “reboot your device, clear cache, reinstall apps causing trouble, not using buggy features, factory reset” and other of this sort.
