I’m planning to get the Google Pixel 7a soon and I’d like to know how GraphenOS major updates are tracked. I’d like to know if these are based on Android or are independent and above all how many major updates we can expect with this OS, 3 years like Android or more?
Thanks in advance.
These are questions that would be better answered on the GrapheneOS forum: https://discuss.grapheneos.org.
You can track GrapheneOS releases on their releases page: Releases | GrapheneOS, as well as from their social media, Matrix room, and an RSS feed.
GrapheneOS is based on Android, and will support the phone as long as Google supports it. You can check the dates here: Learn when you'll get software updates on Google Pixel phones - Nexus Help.
