Basic Security Pixel 9a with GrapheneOS

[Divine_Barakah]

Yeah, I'm asking because I also noticed significant battery increase on my Poco X5 Pro after uninstalling all HyperOS garbage and using Control D system-wide.

I've also played and able to install Debian using Termux and Termux:boot to install self hosted searxng + nginx + local https, it works well but lot's of works for maintening up-to-date and run all maintenance scripts like upgrade/check/clean, and android keyboard for doing that are a total mess, i've to connect a usb keyboard, so i'am done with that, i 've IVPN and it suit my needs. I preferer by far using searxng +nginx + https locale on my Debian distro, work like a charm with alls maintenance scripts :

I know. I refuse to install something that is maintained by some random user with unknown intentions. Too big security risk for me. If it was developed by some kind of foundation like GrapheneOS I'd trust it and install it.

Exactly what it says. Each sign-in presents users with a different keypad layout, i.e. re-positions the numbers on the keypad, to avoid over-the-shoulder PIN theft.

LOL, don't drink/smoke/..... too much otherwise you will lock your phone

Here are exploit protections available in GOS. Please let me know of any other Android or other phone OS that has these protections.

• Hardened memory allocator
• Memory tagging
• Secure app spawning
• Native code debugging
• WebView JIT
• Dynamic code loading via memory
• Dynamic code loading via storage

I did a quick research and it seems those protection modules are GOS-exclusive
