When I purchased a month ago my PD tablet it said "1GB memory" on the box. I've inserted a 4gb SDcard and replace the internal 1GB SDmini card with a 16GB SDmini card. When I load the "Settings" widget and check the "SD card & Device storage", the 4GB SDcard display status of fine, but the Internal Storage capacity says 7.38GB available, not 16GB. Where did the other 8.72GB go? But when I load another apps "SysInfoTool" it says Internal Storage Total: 188MB, Free: 56.80MB and Memory Total:198MB, Free: 102MB. How did I go from 1GB memory to 198MB memory and 7.38GB of Internal Storage to 188MB Internal Storage? I'm confuse! Can anybody shed some light on this?
