I have a Pixel 4a which has just reached end of support for Android. However, I love this phone and the only hardware issue is that the battery doesn't last me scrolling social media all day, so I am not looking to upgrade to a newer handheld just yet.

I've been looking into Graphene OS and Lineage OS as perhaps alternatives I should consider, at least just so I can keep getting security updates. However, looking through GOS, they say that their 4a build is an "extended support" build different from the main OS which is described as a "stopgap" before upgrading phones. LOS says it's supported but through an automatically generated page which doesn't leave me with much confidence about the attention and stability of the build on my particular phone.

I'm asking y'all's opinion on whether I should even bother. Security upgrades are important, but my phone is a secondary device at best, one which I always use with the same apps and websites and honestly not really that much of a security risk. Watch hubris get me.
