I had the exact same issue and have found the perfect solution. what works for me is (as is usually the case with Android) a combination of two tools:
The first is a versatile and lightweight notepad such as Sketch from MG (you may use your favourite alternative, but for many reasons Sketch is the best solution available):

and couple this with DropBox from DropBox inc. (again, you may use your favourite alternative, but for many reasons DropBox is the most ideal solution):

The beauty of sketch is that its one button save tool, and supports both writing and drawing in the same application.
Install Sketch first, scribble on the screen and click save (this creates a folder called Sketches in the default storage area on your device)
Note: Sketch costs about a dollar for unlimited use for all of eternity. It does not require you to sign up for anything. Sketch has also been verified free of malware and phishing algorithms
Second, install Dropbox and add the Sketches folder as a Dropbox sync folder.
Note: Dropbox is a free app, but you have to sign up for it. You get 4GB of storage in the free edition. For unlimited storage you have to sign up for extra, but you shouldn't ever need to as notes are tiny files. Dropbox has been verified free of malware and phishing algorithms.
Repeat this for all devices you wish to share notes over and realise how advanced the world has become.
