File corrupted, help
the file has corrupted suddenly for no reason, it now weights 2kb, the zip-repair trick does not work, i’ve lost 2 days of work, is there any hidden way to somehow find an autosave or previous version of the file somwehre on krita or in my android storage?
this app really needs attention to the crashing and file-corruptment department, or i’ll sadly have to switch as i work from this 
If you rely on computers to earn a living, then you know they are not reliable or secure, nor do they care about your work. The real attention to the crashing issue should be paid by the user, who makes backups onto separate media as frequently as the importance of the work demands.
Of course, this does not help you in the slightest now. Maybe in the future.

Hello @LiterallyMiguel, and welcome to the forum!
Unfortunately, @NotBob is absolutely right.
For a very long time, Krita offers tools to help avoid these hard landings of users, in Krita you find them under ‘‘File’’ >> ‘‘Save Incremental Version’’ CTRL + ALT + S and ‘‘File’’ >> ‘‘Save Incremental Backup’’ F4, so a simple shortcut used a few times an hour and your pain wouldn’t be as deep as yours is right now, but Krita can’t help if users refuse to make use of them.
Or, what happens also very often, users “assume functionalities”, like Krita’s crash recovery, which has the very unlucky chosen naming “autosaves”, but how it works and for what it is, is described in Krita’s manual, reachable via F1, everyone could know what it does.
Here, and in many other topics, I describe how to create a safety cushion for your future work with Krita, but you have to make use of it, without you acting nothing changes, and you’ll fall on your face again:

I don’t know if the android version does it the same but Krita at least creates backups in case something gets wrong while saving. The File usually has the same name but ending with ~ in the same location. (Exact settings can be set up in Krita, like location, prefix, interval and so on). If you’re lucky it’s still there and works and you at least didn’t lose all your work.
I can understand your concern. Nothing wrong with hoping for a bug fix, as many softwares don’t crash and many computers do run well. A good basic backup being done is fine, but not instead of crashes being fixed. I can recommend the plugin Oughtasave, which I’ve used for a year or two without issue (I’m on Linux, running a recent nightly appimage, but have just tried out the latest stable release and Oughtasave seems to be working fine there too). It does incremental saves in the background, which is really useful; a nice extra backup to have.
