Every time I go to install a new app, I get the message "Insufficient storage", and an unable to install anything!

I am using Samsung GT19060 my internal memory is 8GB. I have not downloaded anything but anytime I try to download something it will tell me low memory space.

Clearing the data of Google Play or the Android Market may free up some space. You could also check with the DiskUsage app to find out how data is structured on the internal memory and then delete any unused data. – webyz May 14 '12 at 19:48
how do I clear the data on the android market? – Ephraim May 14 '12 at 19:53
Should be something like Settings | Applications | Play Store | Clear data. Might help to "Force Stop" the app first. – Al E. May 14 '12 at 20:15
This problem is related or even identical to the one described here: Something is secretly eating up my tablet memory and I need help finding it, so the list of possible steps to take described there might help you as well. – Izzy Aug 8 '12 at 22:26

In short: 25 MB free internal storage is minimum requirement (source: TechniPages, AndroidCentral). If free space falls below that, the "insufficient storage" error is triggered.

For details, see:

And many more -- this is a quite "frequent question". For more results, simply follow the tag.

On a lot of devices it's set to 10% of the partition size rather than 25 MB, which is pretty absurd on devices with lots of storage. – Matthew Read May 14 '15 at 3:58
Full ack to both: Yes, some have the 10% rule (which was not clear to me at the time I wrote the answer) – and yes, with today's devices mostly having at least 4, 8 or even 16 GB internal storage, that's an absurd rule at least for the latter two. But nothing we can do about that, unfortunately (except for installing a custom ROM maybe) … – Izzy May 18 '15 at 9:32
Neither of your source links contains the info about 25MB – Maksim Dmitriev Sep 3 '15 at 11:41
@MaksimDmitriev content of the linked pages changed meanwhile. My answer is from 1/2013, TechniPage has renewed its contents in 7/2015. I wouldn't have mentioned sources not backing my claim :) As for the 10% rule, see here, and also see our insufficient-memory tag-wiki. – Izzy Sep 3 '15 at 13:21

The other 200 MB is reserved for future purposes e.g.

1.Saving cache onto disk to free up RAM

2.File System

3.Moving some processes data to SD/ Flash Memory

It is recommended that you have at least 300 MB free space in case you want to install apps. And I'd recommend using a cleaning tool such as ccleaner because android is not good at memory management.

I had this problem with my galaxy tablet and what I did was basically go to app info on all of my apps and tap move to sd card if it let me. It seems to do it automatically on its own now.

It seems the OP already has done that: I have spent quite a long time moving every possible app to the SD card – Izzy Dec 29 '14 at 15:05
