GrapheneOS recently added secure paste: https://grapheneos.org/features#secure-paste

A long time ago I wrote a dictionary app for my own use, which would show word definition upon the word being copied into the clipboard (e.g. from an e-book reader app). The dictionary app would run in the background and only show the pop up on clipboard event.

Then around Android 10 they tightened security and decided background apps can no longer receive clipboard event. Which makes sense from a security standpoint, but it totally broke my dictionary app. I just wish they're a way as a developer to get around it with my own app.

I've always been irritated by the lack of control on whether apps can inspect the clipboard or not.

The bpost app (Belgian national post) immediately reads the clipboard when it gets opened and I hate this behaviour with a passion. While on the other hand it throws a fit if it ever detects an unlocked bootloader, root access, "suspicious" apps or whatever.

I ended up confining it to an outdated phone with a stock OS along with the bank and identity apps that I cannot avoid. I digress, but the original cause of my irritation was indeed lack of control on my clipboard that ia had noticed thanks to that small notification.
