Ok, changing phone setting made it not go offline all night.
How many coins do you guys get per day?
sorry, can I ask you which settings did you change?
thx
In device maintenance I had a warning Electroneum was acting unusually, I only opted to ignore this. Since then it has been ok, might be a coincidence or a temporary fix.
You need to find a setting specific for your phone.
You could join Android Central forum and ask the question for your specific phone. It might help.
