Restored my phone last week, now my screen of memo saves strait to Samsung notes and will not save on the lock screen. I have gone through all the settings, cleared the caches. It worked for before the restore. I figure a restore will fix it but not in the mood.
I just tried the Lock Screen memo. I don't see a way to "SAVE" it to my Lockscreen, although I am able to "PIN" the Note to my Lockscreen. (just click the Pin symbol at the top left) A message popped up & said the Note would stay on the Lockscreen for 10min & then my AOD would be displayed again, & the Note could be viewed again by pressing the "Pin" again.
So, there is 1 thing I think you need to check.
Do you have AOD (always on display) turned on? If so, then yours should function just like mine did.
If the AOD is turned off, then I "think" I'm not 100% sure bc ive never done it, I "think" it might be possible to save the Note/Memo as your Lockscreen picture, but I pretty sure you cant save multiple notes/memos to your Lockscreen, like you can with S. Notes. I believe you might be able to save 1 single Note/Memo as your Lockscreen picture IF AOD is turned OFF. I hope his helps.
