Every app crashes constantly, but the most affected was the clock app I used for alarms. I had to buy a shitty little alarm clock because of this.
Anyways I have a galaxy s8+ and I was going to install LineageOS, but the S8 line is the single only galaxy that has no official support for that OS. Any other distros I should look into, or should I just do a default installation?
Have you checked out the xda forums for your device? There might be an unofficial version of LineageOS.
