Before Android stopped publishing device trees (having them isn't essential), not releasing AOSP source code often and the lead GrapheneOS developer being conscripted, updates were very often and new versions of android were released usually within 2 weeks of release.

# Why GrapheneOS?
GrapheneOS is much more secure than other mobile (iOS is close) and any desktop operating systems

This makes GrapheneOS the best mobile OS for people for anyone including regular people and those who want or need security and a private phone. GrapheneOS is also the best mobile OS for your Monero wallet, Signal/Molly/Simplex or as a NAS.

GrapheneOS provides users with a better day to day experience by adding a network permission toggle, sensors permission toggle, scoped storage and contacts, more and better user profiles.

# How to install GrapheneOS
There are two officially supported ways to install GrapheneOS, the CLI and the Web installer.
https://grapheneos.org/install/

For most users, you should use the web installer that can be ran from another GrapheneOS device or regular Android device as well as Desktop.

Remember to follow the post installation instructions to make sure the bootloader is locked and OEM unlocking is disabled.

When booted into the device, open settings > security & privacy > more security & privacy > turn off allow sensors permission to apps by default.
# Notes
Google apps such as Google Camera, Google Photos, Google Dialer and other pixel exclusive apps will work on GrapheneOS, some apps might need to connect to the internet for initial feature flag fetching and feature downloading but can be turned off afterwards.

Google Pay doesn't work due to Google but you can use Google Pay on Pixel Watch instead. UK and EEA users can use bank tap to pay or Curve/PayPal.

Google Play Store/Google Play Services is optional. To install, open the App Store to install Google Play.

To activate Firebase based app notifications, install the Google Play bundle and open Play Store and click log in to initialize it. Make sure Google Play Services has a battery optimization exception. This is user profile specific.

You can install Cake Wallet, Cupcake and Molly from Accrescent https://accrescent.app that is in the GrapheneOS app store.

Install apps from Accrescent where possible for security purposes. Google Play with a throwaway account is another good option. Both have full unattended app update support. Obtainium is an app that lets you download from Github, F-Droid (prefer non F-Droid where possible) and other sources. https://github.com/ImranR98/Obtainium

My app is crashing! GrapheneOS will usually tell you why the app is breaking and how to fix it. If you click more details and the error log mentions SIGSEGV or SIG something, its usually memory hardening related. Hold down on the app icon in the app draw or in recents and click app info then scroll down. You can turn off protections one by one until it works or turn on the compatibility mode toggle to disable everything.

I got a "App tried to perform DCL via storage/memory" when trying to open my app. You can click the notification and click allow and the error will stop.

I got a "App tried to access sensors". You can ignore this or expand the notification and click don't show again. If the app does need sensors such as a compass, step counter, map application or camera/video application, you should generally keep the sensors permission enabled for those apps. Most apps will say try and access them but probably won't need them.
