Sorry to hijack this thread but I was wondering what to do if you do get a low memory message? I don't want to install a task killer but as its my first android, am not sure what to if I encounter this.
I had the low memory issue a few time 'Disk Storage Space is Low' and solved it by a combination of uninstalling seldom used apps (you can always quickly re-install them if you wish on an ad-hoc basis) and clearing the cache and stored data on apps such as Facebook (which seems to love clogging up the device memory). Hope this helps?
Yes (sorry it took me so long to see your post there NikkiC), this message is the result of a different type of memory running low- storage. Task managers are unnecessary in Android (see el President's post above) but they free up Random Access Memory (RAM) which is not used for long-term storage.
The message you are seeing is the result of storage memory running low/out, and is the ~1.74 GB or whatever partition (division of the storage memory). Uninstalling apps will free up space here, and I have noticed that some poorly coded apps "expand" the more you use them (instead of storing the cache and accessory files on the sd card they are stored with the app) and so I have gotten that message without installing any new apps! Also, updates sometimes add to the storage space the apps take up so you might get the notification shortly after updating apps.
There is also a ~9.8 ish GB storage partition that is for your media and text messages and email attachments, etc., and while I am sure it kicks up a notification as it fills up too, I have never done so and it would probably say something like "SD card memory is low."
