I got a new permanent friend: An upward-pointing arrow in the top right corner. It first visited me some time this afternoon and now refuses to leave. It should indicate, that an app is using the location service, but it can't get rid of it. So far, have I rebooted, done a Deep Clean of the memory with XSysInfo, removed all apps from the Multitaskbar and also done a soft reset. Once the device powers up, everything looks normal, but after a second or so, does the arrow come back and stays. Any ideas, as to what might cause this? I am befuddled: My iPad doesn't make sense.
