So I got a lemon you mean?? well that's part of me being overwhelmed. Like I told you I had a Redmi 4X for 5 years now no problems and it was a budget model, and this one is full of issues and things and everything is a bit crooked
Thanks though you gave answers to a lot of the questions I had.
When I get bold enough I will try to flash some other rom that is smaller.
Well it's more that you bought a device with too little internal storage. If it does support A/B that'd be a big reason why you have so little free space left on the device out of the box/even with a clean flash. Generally I'd recommend 128GB as a minimum these days due to the system taking up twice as much space as it really needs to, and usually 256GB on devices that don't have a SDXC slot for expandability like my Poco F3.
My previous phone, a Redmi Note 5 Pro didn't use A/B partitioning for updates and had 64GB of internal storage, but even then I had a 128GB sd card in the second sim slot. My wifes was the same phone but the 32GB model along with the same SD card and she wore out her internal storage.
Here's a link to Treble Check on the playstore so you can know for sure whether that device uses A/B or not.
Check your device for Project Treble support and more
Google implemented it to help with OEM rom upgrades to help folks that had a bad flash return to a working system, and to make updates more seemless with background installs. Though for us running third party roms, it basically just ends up stealing space from us, since most non-OEM roms don't take advantage of both partitions for seemless updates.
