I’m using a Google Pixel and for awhile I was using stock, mostly just because after having custom roms on my previous devices I didn’t want to have to deal with trying to get apps to work, I was building my unofficial lineage to get some tweaks I wanted. However I’m back to using Lineage again.

I believe that’s the only way… But I could be wrong. I had them all stored on an external hard drive, and used the CLI to upload them all.

Using a Pixel 5 as well. Before that I had the OnePlus 6 for 6+ years before I decided I wanted a smaller phone again. While it at times still seems a little slow, it still works great. I replaced the battery about 3 months ago and it has a great battery life again. Running Lineage.
