So this has been happening for a few months already. My LG G2 mini running on Android 5.0.2 constantly runs out of internal memory for no reason. I've uninstalled many apps and moved a lot of files to my SD card. But after some time I get the same warning. I've Googled for help and apparently it's because of some hidden file which I can only reach by entering some codes through my phones dial. I've tried but got another error (can't actually remember what it was). Does anyone know how can I get around this problem apart from a factory reset?
