I have a rooted and custom rom android phone running an official lineage os release

It still can't make phone calls without cycling airplane mode between calls.

The one before that would crash if I paired a bluetooth device while connected to one already.

Both of them bootloop at the power off battery charge screen, which basically means i couldn't turn my phone on while plugged in, and unless its a fast charger, the act of repeatedly booting up keeping the phone screen on ends up draining power faster then it can charge.

So. Tell me again about these free and open options.
