Many thanks to Lineage team for Android 11 on a 2014 device!
Have just come from 17 clean flashed (can't remember which release) and it was by far the worst experience I have had with this rom, GPS flat out didn't work could not use google maps for navigation and WiFi would flicker on and off if mobile data was active also the sim would fail to be recognized on reboot often requiring multiple restarts to get it to give the sim pin screen at boot. That and it became horribly slow and would regularly freeze in apps etc.
Just upgraded to 18 as per this post and it's running flawless, GPS works, WiFi stays connected and sim always detected at boot (haven't experienced sim death yet). Much better experience over all for daily use.
Have noticed though, I've been running this rom since LOS 15 or 16 and I feel like with every clean flash after about 6 months or so it begins to slow down and become just like I recall the Stock Rom being. After a clean flash to the new version the phone always runs like brand new again. Just wondering if there's an explanation or a fix for this occurrence?
