I frequently get said notices popping up at the bottom of the screen throughout the day, no matter what apps I'm using. I've owned another Z5 Compact in the past, and this never happened with it. I reboot every so often and it doesn't help. The message isn't clickable and goes away after a second. It doesn't seem to affect the phone's performance, but it would be nice to stop getting the message. I have not yet tried factory resetting but I will if no other solutions pan out.
Also, my phone is on Android version 6.0 and says there are no updates available. The Xperia Companion software says the same thing. My customization version is 1298-7299_R9C, if that helps.
