Mobile me not updating
Running out of storage space to install new apps used to be a real problem for Android phones, particularly budget devices that may have come with only 4- or 8GB of storage built-in.These days Android phones have larger storage capacities as standard, but if you get a bit too trigger-happy with the camera or run away with yourself in the Google Play store it's still reasonably easy to run low on storage.There are no obligations from the manufacturers to support updates for older models.As a precautionary measure, it's good practice to back up your data such as contacts and photos.
If you've cleared out all the files you don't need and you're still receiving the "insufficient storage available" error message and don't really know why, you need to clear out Android's cache.
On most Android phones this is as simple as opening the Settings menu, browsing to the Storage menu, tapping on Cached data and selecting OK to the pop-up when it prompts you to clear cached data.
You can also manually clear the app cache for individual apps by going to Settings, Apps, selecting an app and choosing Clear Cache.
If an Android update is available to your device you'll find it in your phone or tablet's Settings menu.
However, just because a newer version of Android exists it doesn't mean it will be available for your device - now or ever.
We cannot say exactly how much free space is needed, but Google recommends a minimum of 1 GB of free space when installing or updating apps.
