For most of the problems I mentioned earlier (in the Dutch Community forum), I have now found a solution myself.
Not yet resolved:
Create my own notification sound for incoming mail and any other notifications.
For a phone call I could, without a lot of problems, introduce my own notification sound.
I have the A50 today for one week and have already done a reset to factory settings due to various problems.
With my previous S4 Mini, setting up your own notification sound was a problem…
I use the Google Mail app with two accounts.
The own sounds like the S4 mini have a "wav " extension.
PS I still have another question related to "questions and Answers " on the community forum: If I receive an answer or a question how or where can I reply? By mail or forum?
I am glad you have found a solution to the issues you identified. Can you please outline what the solutions were?
