After a damn amount of time I've been considering it (a lot of data in there and I'm lazy), I've finally wiped the android clean (dalvik+cache+the rest). Happened exactly what I was expecting:

All in-app errors (even devRant feed) magically disappeared. So, if you experience something like that, don't be lazy and wipe.

Also there's speeding up of the system and other pros of wiping, but those aren't that important like getting rid of errors ^^

If you need to wipe your OS clean often - that just means you're running a shitty OS. Are you running a custom ROM?

@xroad I don't need to wipe my OS often, I don't need to wipe it at all. I was just playing with it a long ago and as the time went it filled up with my shit. Then I (soft-)bricked it at a festival (because edit system files at night, after concert, in a tent... what could possibly go wrong) and probably forgot about dalvik and filled it with shit again. Worked quite well and I started to notice annoyances too late, hehe.

So it kind of... took a while to move shit into laptop, wipe everything accurately and move it back. :P

Also, no, custom rom isn't an option for me unless Samsung releases the drivers for S-pen.

You could have just started off saying you had a Samsung phone lol.

I worked on one of the first Galaxy devices. Maybe that's why I hate the company so much.

@xroad Ha! So when something breaks again on an old Ace I have somewhere in my room, I know who to blame, hehe. *joke*

Only the company, or the devices too? ^^

@KeyWeeUsr well I'm not a fan of their culture but I do think they make some decent products. Definitely don't like their devices though
