[Android Stick & Console RockChip based Computers] Barkuti:
Yes I already knew Jumobile System App Remover, lots of thanks to the fellow or fellows who make it. Well done and super useful…

Galaxy S2? LoL! That's even earlier than my initial Moto G first version with 1 GiB / 8 GB, the one with so little user storage which I was forced to delete WhatsApp chat backups to clear up space. I ended up installing an optimized image with SuperSU application as root manager in it, it provided a nice storage space boost back in the day. I conserved it until the half of 2017. I am also still running a good old HP nx9420 (upgraded to Core 2 Duo T7400 and 4 GiB RAM, but limited to 3.375 GiB useable RAM due to 32 bit chipset), and sincerely I need an upgrade. Despite optimizations, it swaps RAM in the pagefile sometimes (just the browser uses a lot of RAM nowadays if lots of tabs are open)… It has the best trackpad design I've ever seen, though: works well, it's small and is slightly depressed so no way to touch it with the palms of your hands while typing; gotta :cry: miss it.

I had a more modern second hand laptop a few years ago, and soon after setting it up I got really fed up, due to its enormous trackpad getting in the way of my palms and the pointer moving all around for no reason. I solved the problem smashing it with my fist a la Bud Spencer, one hit was enough for it to not even power up again (LoL!). :ROFLMAO: As you can guess, I need to solve my economy and embrace prosperity; gonna work on it via mind reprogramming very soon.

But, if there is no link to run the SuperSU application from the launcher, how the @#$% are you supposed to easily manage root privileges for applications? :unsure: I understand that this can be done with shell commands (I started with shells in the late 80s with CP/M as a young teen, and the only shell which I more or less mastered was the one of MS-DOS somewhat later), but this is more inconvenient than using a good super user application like Magisk. Using shell commands is powerful and still has its place, but not for everyday use. 🙄 Answering myself: maybe installing SuperSu.

“Enter” emulates a click? No, what is happening is caused by the bug in the generic key layout file “Generic.kl”, located inside the system partition folder in “/system/usr/keylayout/Generic.kl”. To fix the error you must edit the file and go where it says “key 28 DPAD_CENTER” and replace it with “key 28 ENTER”, this is described in the article I linked from NoviSign. Remember these are key scan codes, and so what the Android system is receiving is a DPAD_CENTER key code whenever you hit the ENTER key (instead of receiving an ENTER key code). So it is NOT a “q”, that is incorrect. For example, I remember getting different letters or key codes when I pressed ENTER when searching applications in F-Droid after having input some text in its search bar (probably the last input key letter); you could also write some text first in a browser's omnibox, hit ENTER and see what happens; or go to wifi settings, connect to a wifi network and enter its password using the physical keyboard and its ENTER key (take note of what appears briefly onscreen when you hit ENTER). In essence, I remember that different characters or key codes were involved, because this is the way the Android application being used was interpreting the received DPAD_CENTER key code.
