Turns out there is another side issue which wasn't there before: the device has now gone REALLY slow. Like when you type something into search, it clicks out at about 1 letter onto the screen every 2 seconds. I couldn't say with 100% certainty whether it was like that before the last system update as I hadn't used it for 2 years, but it definitely wasn't there when I last used it in 2023. Device seems to be happy otherwise. The onboard storage is pretty full (1GB free out of 14.2GB) but there is plenty of space on the SD (11.3GB free of 14.6GB). It is the same SD card I've used from new. Is this also a recognised issue that can be tweaked? Thanks.
