Not being open source ≠ not safe.
Microsoft ships hardened Chromium basically, with sandboxing turned up to eleven.
They also run their SmartScreen filtering on top of that.
Also, Firefox is more private, not secure. Either you run LibreFox or it’s less secure than Edge by default.
I do. It’s more secure than any other alternative. Not private, but really, really secure.
So I tested both FireFox 
and Edge 
real quick and it’s true.
Although, I enabled every security and privacy setting on both (just about the same set of extentions also). But even then, even with a lower score, Edge still feels much smoother to use. Also, every time test refreshed, FF flashed white for a split second as opposed to Edge’s black. Since I use dark mode and Dark Reader, it’s extremely annoying on FF’s part.
I wonder why. 
LOS heavily hinders feature set, though. I wouldn’t recommend to anyone that’s not a techie, especially with MicroG.
Samsung features that’ll get removed are:
• Camera. It’ll work in LOS but quality will be much lower without Samsung’s processing.
• Standby time. It’ll last a lot less as LOS doesn’t kill background apps like OneUI does.
• Any sort of audio video enhancement. Dolby Atmos will be completely gone. HDR enchantments won’t be there either.
• Samsung DeX.
• HBM won’t work automatically. On OneUI, if system detects you’re under direct sunlight and auto brightness on; it’ll boost the brightness above regular maximum. You can have this on LOS via LiveDisplay but it isn’t automatic afaik.
• Phone will get hotter when it’s used while charging. OneUI both lowers charging speed and lowers performance (unless you’re in a game) while charging. LOS doesn’t. It might get uncomfortably hot compared to OneUI.
• Noise reduction in voice calls barely work under LOS. This is especially true when calling on speaker, LOS is borderline unusable when there’s even a little bit background noise.
Switching to LOS for a techie is fine, but recommending it to someone who you don’t know how they use their device isn’t great. If OP watches a ton of movies, OneUI will have much better experience. If all OP does is social media, LOS is completely fine.
There are basically no ads if you buy Samsung S series without a carrier.
Honestly that just shows bug report templates/rules are too hard for most users.
Ah yes gender politics, only thing missing from Star Trek themed discussion.
