[Samsung Galaxy A20 Questions & Answers] ThePooBurner:
There are threads upon threads upon threads of things you can do with every other variant of the A20, but almost all of them have the disclaimer "Doesn't work with A205U." This is making it pretty hard to find guides for things that *can* be done with the A205U. Perhaps if someone could compile a list of guides that work for this stupid outlier of a phone it could be of great use to the community.

Specifically, this phone seems to have a terrible storage management issue. You uninstall things and it doesn't free up all of the space that was being taken by the program. Without installing anything new, after having done a factory reset, and only updating existing apps, my free space went from 9gig free to only 5 gig free. No amount of cache clearing has remedied the problem. Indeed, the reason i did a factory reset, after putting it off for like 2 years, is because i had reached the point where i only had ~800mb free and had to clear all app cache every day, sometimes multiple times a day, to keep the phone functional. The free space seems to just disappear into the nether. If there is a way to get this to stop, or at least how to get all the free space back without a factory reset, i would go full Jessica Simpson and LOVE YOU FOREVER if someone let me know how.

Related: Since almost everything out there for doing full back-ups requires root: is there a way to back everything up without root? So non-stock recoveries work on the A205U? Can i put TWRP on this thing?

Somewhat related: The samsung Message App stopped storing messages as SMSs and now stores them as Chats, which means my SMS backup program no longer has anything to back-up. I didn't realize this and ran my backup, thought it got everything, and then re-enabled "delete after 200 messages" so that the database could be cleared and i could get storage space back, and turned it back on after it had cleared everyting and freed up ~700MB. Then when i went digging through my back-up database looking for information i discovered that the "chats" had not been backed up. Is there a back-up solution that anyone is aware of that would not have this gaping flaw? The program i used hasn't been updated in years, but i haven't come across one that will back everything up to an IMAP server (or something like unto it) which allows the messages to be searched from anywhere without the need of a desktop or database app.

Additionally: Is it possible to use Odin or Heimdal or some other tool to make a full flashable image of the A205U from the phone itself? IE: i factory reset, get it setup with everything i need and all accounts restored etc., and then take an image of that, and then when i need to "reset" the phone again i would just be able to reflash that image/snapshot of my perfectly setup phone, restoring it to a "factory reset" type state, but without having to go through the hassle of a few days of downloads and setup again.

Penultimate: Is there a way, without root, to fake the phone type to the Play Store so i can install things that "aren't compatible" but actually are?

Lastly: Has anyone managed to get Diablo Immortal to run on an A20?

Many many thanks for any help that can be rendered with these concerns. Especially the storage one. My wife and I both have the A205U, and cannot afford new phones, and the storage thing is driving us both crazy.

PS: does it brick the phone if we attempt to flash it to the firmware of another A205 variant, like the A205S (for which guides seem to abound)?
