Keyboard and music hickups

I experience some weird problems with my new Fairphone 5. I can not distinguish if it is caused by apps I installed or the amount of memory used. Or if it is a bug in the phone. Sometimes the keyboard just dissapear, and it takes a few seconds before it pops up again. And at random moments music or a podcast playing just stops. Sometimes that seems to be connected to opening another app while playing. Does anyone have similar experiences?

Hi, to me this sounds very much related to this topic:

However to my knowledge there is no solution yet.
