Memory Full Error on Galaxy Ace
I've had thes message, and it's really annoying. It is because the phone's internal memory is a very low 160Mb. With the operating system and all the "standard" apps, this soon gets full, and when you get below about 18-19Mb free you will get this message.
The only way I could stop it was to uninstall some apps I had downloaded until I had about 20Mb free. Suddenly tests came flooding in.
The upshot is you can only install a few apps before this happens. Rubbish really, as other similar phones have 4Gb of internal storage. The size of your SD card makes no difference, as we're talking about the internal phone memory here.
If anyone knows another (and better!) way around this, please let me know!!
