Acer Iconia B1 Tablet 8 GB Internal 32 GB External (Micro SD) Android Version 4.1.2. My Acer Tablet keeps telling me that I have insufficient memory even though I have uninstalled a number of apps. The Android Storage App gives the following information: INTERNAL STORAGE: Total Space 0.98GB, Apps 744MB, Available 109MB. INTERNAL SD: Total Space 5.17GB, Apps 66.67MB, Audio 5.26MB, Downloads 16KB, Available 5.1GB. EXTERNAL SD: Total Space 29.71GB, Available 28.83GB. When I connect my tablet to my PC, the Windows file manager reports: External SD 28.8GB of 29.7GB Internal SD 5.08GB of 5.17GB Could anyone please explain why I keep getting the "insufficient storage space" message and how can I correct this problem?
