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!
Use a VPN. No reason not to if you're concerned about privacy—otherwise you have no privacy as your ISP can monitor you. If cost is an issue, ProtonVPN has a free tier, otherwise I recommend Mullvad as an affordable and really reliable and decent option imo. I found ProtonVPN's connection to be kind of volatile when I used it (I paid for it too, on the highest tier). Mullvad has always been super reliable though. Whenever I've had connectivity issues it's always been because of whatever network I'm connected to, not because of Mullvad.
Yeah I probably should but the WiFi at work doesn't let wireguard through (I have a wireguard server running on a VPS)
