First of all thanks for working on the ROM, it's much appreciated. I am using VNS-L31 and the install process went smoothly. I did a fresh install, no gapps and no magisk. Just two apps installed so far.Great job with the ROM, it's awesome to see people still supporting these older phones unfortunately I have also been having problems with apps like F-Droid and Osmand running out of memory, like @unrealdtc. I flashed F-Droid privileged ota after flashing the ROM. Osmand locks up after a few seconds and F-Droid crashes when it tries to update the repositories. Didn't install Gapps though.
However, I have the same issue that F-Droid runs out of memory when fetching updates and then crashes.
Furthermore I am running subtracks for listening to music and it's working, but does not show any covers wich might be some permission issue.
