It doesn't seem to be an option with this phone that I've been able to find, I've heard there's a way to get around it but if there is I haven't been able to find any details. Failing that, is there a way to upgrade the internal storage? I have 10 GB internal but right from the start almost 5GB was used by the system and "essential" apps that can't be deleted, which makes it extremely hard to download or update things.
