I am currently using 4 banking apps from 3 different banks on GrapheneOS, they all work just fine. I'm also using WhatsApp and would not use the backup feature to Google Drive even on PixelOS. Uber (haven't tried the for drivers app), and other ride hauling apps also work fine.
Why would I choose LineageOS instead of GrapheneOS? I can't see any benefits in using LineageOS, I only see major drawbacks.
Why is it always 0 or 1 with privacy? Why can't I use GrapheneOS with sandboxed Google Play Services? Seems like the best option. I can still use all the apps I want and also get privacy and security benefits. I only give Google what I want and still get to live like a normal person, without making huge compromises on security, privacy, usability and GrapheneOS has been the most stable OS I've used. More stable than the stock PixelOS.
Yes, all notifications work fine with sandboxed Play Services installed. All my banking apps also work fine. I haven't really had any problems with app support or any other problems for the many years I've run GrapheneOS as my daily driver.
If you allow root, there is no need for additional privEsc exploit. Also does LineageOS actually ship security patches reliably for software and firmware? How is Magisk helping to resist attacks?
If you are fine running an OS with horrible security and privacy, then LineageOS and it's forks are fine. If you want the best privacy and security, then GrapheneOS is the best option.
This just doesn't work the way you think, this mentality is not just outdated, but dangerous. People who think like that are more subject to "low IQ" attacks than people who accept the fact they are subject to the same "low IQ" attacks that work on everybody. You are overly confident. You can't be 100% alert and suspicious 24/7, around the clock. At some point you are tired, your attention is elsewhere or you are just not up-to-date on the latest techniques that attackers combine with some form of social engineering.
Also no matter how technical you are, it's almost impossible for you to detect zero-click 0days for which you are more vulnerable to than people without root privileges. You running rooted OS actually become easier and less costly target than people without rooted OS.
No root is a major security feature, you have chosen an OS that prioritizes security.
Use some other browser if dark mode is really important to you.
I think the launcher is good and I can't think of anything to improve on it. I'm happy it's the default, but I'm sure you can switch to a different launcher if you want.
Pattern unlock is also not there because of security.
