GrapheneOS – When an App Is Slow

A GrapheneOS user discovered that the Osmand map application runs significantly slower on their device due to GrapheneOS's hardened memory allocator, which creates overhead when constantly loading and discarding map data. The performance issue can be resolved by disabling the hardened memory allocator specifically for Osmand through the app's exploit protection settings, though this comes with a minor security trade-off that the user considers acceptable since the app doesn't load content from the internet.
