Cache partition and Dalvik cache can only be deleted in recovery mode. The minimalist emergency operating system does not have a graphic user interface but consists of a simple text console that provides access to recovery, maintenance, and installation functions. Device manufacturers define a specific shortcut to start the smartphone in Android’s native recovery mode (stock recovery). With most smartphones, you have to press the “power button” and “volume lower” simultaneously for a few seconds. However, the keyboard shortcut may vary depending on the manufacturer. However, navigation within the minimalist menu is always identical:
- Volume button: switch between different options
- Power button: starting a function
With the option “Wipe cache partition” located directly in the main menu, you can delete the cache partition.
If you want to clear your Dalvik cache, you need to start your smartphone in custom recovery mode, and there are special apps that can help you do this. One of the best apps is the freeware ClockworkMod Recovery. The cache can be cleared through the “Advanced” menu and then selecting the “wipe Dalvik cache” option.
