My phone has 2GB internal memory. The apps (downloaded and preinstalled) add up to <200MB per the apps list. In the last couple days available on-phone memory dropped to 25MB. To free up space I uninstalled unused apps, moved all the apps I could to the SD, cleared caches, deleted old texts. Now memory is down to 18MB and I'm getting messages that there's not enough space to receive texts or install apps. What the heck's happening???
, but it has all the info you need for this.
