I have around 50MB of internal storage left and some 1.7 GB of external storage left in my phone. But when I try to download and install any application from google android store,I get a message insufficient storage and the application though downloaded doesn't get installed. Why is this ? Earlier it worked fine from the same store.
For instance yesterday when I tried to install whats app I got the same message. What can I do about this ?
While not directly answering your question the Apps2SD app might be helpful here, not just to move apps from internal memory but for it's feature to clear the cache of all apps in one go. If you have installed a lot then it can be a bit of a chore to go into each and choose Clear Cache. This app allows you to do them all in one hit.
