Thank you very much for the answers so far.
As I read out here, there are always bugs that are sometimes more or less well solved.
This should not happen with a quite mature operating system. Especially not such different bugs and little things that cannot be removed for years. The lte forum is full of such messages.
What should I think about it?
Should I really switch to Android or iOS?
After all, my Aqua Fish said goodbye last Saturday and does not work anymore. [At the moment I want to do the factory reset, but I can’t get any further]. (Factory reset - recovery not working)(Maybe someone can help?)
