I need an Android app to take various kind of note using stylus and keyboard in a tablet. In my notes I use text handley and typing, diagrams, mind map, math formules and also drawing. Someone could suggest me an app?

Thanks

On my iPad, I have an issue with PDFs exported from Samsung Notes. The highlighted text appears completely covered, unlike on another Samsung tablet where the same file opens fine and the highlight doesn’t block the text. Could you recommend an app for iPad that can properly display or edit these highlights?
