There are plenty of apps that can store far more than 20. Search forClipboard on Play Store . One such app
which doesn't require extra / suspicious permissions is Clipper which I found to be very effective in organising clipboard
You will find plenty more apps in Clipboard Tools, from the curated repository maintained by Izzy , as he noted in comments . Also note that Izzy has pointed out better alternatives in his now deleted comments, needing fewer permissions:
Clipper requires permissions to "test access to protected storage, modify or delete the contents of your USB storage, view network connections, full network access, receive data from Internet, receive cloud messages, run at startup". From a privacy point-of-view, all those network permissions should not be there as they are certainly not required for the functionality of a clipboard: Keep in mind you might copy sensitive information like passwords. Not saying the app intentionally does something bad here – but who knows what some integrated ad/tracking library might do (Clipper contains at least 3 of them)?
So better choices would probably include:
- My Clipboard: only requests "run at startup, reorder running apps, draw over other apps". Not sure why it needs to "reorder running apps" – but at least it doesn't ask for network access, so the danger of transmitting sensitive data is much lower (if existing at all).
- CopyClip: only requests "draw over other apps, ACTION_MANAGE_OVERLAY_PERMISSION" – perfectly understandable, as it needs to draw its action buttons (for copy/paste) on top of the app you're copy/pasting from/to.
