rightAnd stop calling this gsi useless, or any other custom ROM. Gsis by their nature are buggy, they aren't perfect. Sometimes things will not work the way you think it should. You chose to unlock your bootloader, you chose to install a gsi. Noone held a gun to your head. So take responsibility and accept that you're playing a role in your outcomes.
Gsis are built for free, with someone else's time, and you're not paying a salary to the devs or anyone that offers help.
XDA has alot of whiny, complaining, unthankful, demanding users, that forget that what they are using was free to them. You aren't owed anything. Just because something doesn't always work 100%, doesn't make it useless.
If you need the highest level of stability, go back to stock firmware and relock your bootloader. But stock also isn't perfect, it has issues too, just less overall. Or maybe you would be better off with an iPhone, as long as you don't jailbreak it your apps will work great.
