Device memory troubles

[Android Question]

I have a Galaxy SII device, but I'm facing some troubles with the storage device. The storage device is always filled by it's own, and I do clear cache and unwanted apps. There's a message too appears to me about that storage insufficient occupy. Please, help me to deal with that trouble

All media takes up valuable internal storage space. Take a look at your gallery & music & move to the SD Card. Also, if you're storing a lot of SMS/MMS & phone call logs/messages, you may want to clean up what's not needed & look for an external storage option for old SMS/MMS messages.
