Does anybody have experience/knowledge of Samsung phones, specifically the S8?
My wife's phone has developed an irritating fault, since the last software upgrade, we think. The notification bar across the top has spurious figures and symbols superimposed over the normal information, like this:

However, when you drag the bar down to access the other apps, the extra information disappears, and the notification bar appears as it should:

My phone is an earlier version, the S6, which no longer gets upgrades, and this fault has not appeared. Does anybody know what is happening and, more to the point, what can be done about it? In other times we would march down to the O2 shop and play the dim pensioner card, but that ain't possible at present, of course.
Any advice gratefully received.
Cheers,
Chris
