I have not any prior experience with installing custom ROMs, but after trying it out (and getting stuck, and googling and finding answers) I successfully did it. Below is my home screen if anybody is curious:
I use OpenBoard for my keyboard. Unfortunately I am still dependent on Play Store since some of the apps I need can only be found there. Sometimes it feels meaningless committing to this whole thing because I'm not perfectly private; then I think this is better than using a regular iPhone or Android phone.
So far I'm liking it. I am naturally inclined to feel hesitant about using this as my main phone and plugging in a SIM since it's custom, but I'm slowly making the transition.
Feel free to share any beginners advice or your own experience using GOS for the first time. Cheers!
It does function just like any other phone so far I've tested. No app that simply doesn't work. And if it doesn't, you can simply exploit the GOS hardening in settings to improve compatibility. You overall have more control over any app, which I like
~~One of my biggest concern is banking apps not working. Is that still an issue with Custom ROMs?~~ Edit: Nevermind, answerd below
I can add that ive also had 100% success with that setting, but I've only needed it 2 or 3 times.
