Lovegrapheneproject Hello guys, I have three devices right now. Pixel 6a with GrapheneOS, iPad and a Xiaomi Redmi S2. My Pixel 6a is focused on security, privacy and anonimity. iPad is more focused on security and I use my real identity there. Now I want to use my Xiaomi Redmi S2 for things that require root so I'm planning on flashing Magisk on it. Queation is if I should stick to Stock ROM on this phone or go for a Custom ROM? Because either way a phone will be unlocked and rooted. Here is some ROMs that are available: https://forum.xda-developers.com/f/xiaomi-redmi-s2-roms-kernels-recoveries-other.7716/
matchboxbananasynergy My personal opinion is that it doesn't really matter. I wouldn't do anything sensitive on that device at all.
bayesian Agree 100% with @matchboxbananasynergy. Treat that device as compromised, don't put sensitive stuff there.
Crystal As it was already said, don't use it for anything sensitive or critical. I'd flash it with some custom rom, use magisk and use it for account-less games or something like. Something very casual and experimental. There is no value in MIUI anyway.
