I thought for a while that my phone is damaged... This particular model (or Samsung devices in general) has some kind of fault in it - I'd also go for low mic input. I've looked into those xml files in MICGAIN mods (normal and higher) and some values are slightly boosted.
I got the same with V2 version - overall better mic performance during phone calls - people I've talked to said that they now could hear me better than before (with v1 version), but it is still not close to stock quality. I tried v3, but as danwood76 said - it reverts settings to LOS defaults. Call quality is bad as it was before flashing v3, speakerphone is dead as with other versions. No luck there.
We have already completed the 11 bringup. This thread is really just a build of that work.For now i cant test it cause i had to put back the latest stable official rom from Samsung on this spare phone, but, good work, keep it up. I'll try it for sure soon or later.
Maybe you could even try to reach out / join forces with Stricted and the others if that could simplify all of you guys' work on the roms. Idk, just saying.
You cannot downgrade 18.1 -> 17.1. Nor can you flash unofficial builds over the top of official builds (without a special migration zip). You will always get permissions issues and app crashes doing either of those things.same here, And i flash to odin and get back to 17.1 which is more stable, I have a bad experience on this one. When you are on LOS 18.1 and wish to flash 17.1 you can't access your internal after the flash of 17.1 it says access denied, Also my 256GB Sandisk card ended up corrupted on 18.1 however when i connect my sdcard to computer my sdcard is not corrupted. And i flash the firmware from odin and my sdcard was working fine.
Swap/Zram is already enabled, don't use any crappy third party apps that enable it because they will do it wrong.
