Is there a way I can see or edit clipboard entries in Samsung Galaxy Tab S?
native clipboard which used to use Xposed to seamlessly integrate into the system (it was accessed by either the system's paste button or the selection menu). However it was now updated and uploaded to play store, the major update is that it no longer requires Xposed nor root, but it's still seamlessly integrated into the system. By simply double tapping a text filed the clipboard will open,so no notification or distracting floating buttons. Also the selected text from the clipboard gets automatically pasted.

^^The app only Got published last week to the store . I think it's a breakthrough in the clipboards for Android
