Some times while installing new apps or upgrading the apps from Google Play store, we get an error : “Insufficient Storage available”
This error comes even though the phone shows enough internal memory available.
You can free up a lot of space by deleting Dumpstate / Logcat.
To do so, dial the following code from your dialer app : *#9900#
You will see lot of options; Select : “Delete dumpstate/logcat” to delete the logs.
You can check how much memory is free from the settings.
Go to Settings > Storage. Check the available device memory.
