phone memory very low, help.

[#1]

I consider myself pretty phone savvy and I have an 8gb memory card in my phone yet where is all my phone memory going?? I am down to 2kb!!! I am so low it keeps prompting me to delete files to do anything. I only keep like 5 text messages at any time I am good about deleting them and vise versa for sending messages/mms. I have all my photos on my memory card. Any suggestions on what I can delete to get my phone memory higher again?? Are applications stored on the phone...and if so what are higher memory suckers to get rid of lol. THANKS!!!!!!!!

did u install a lot apps on ur phone? if yes, did u install it on phone memory?

i think u need to see first what apps have u installed. check it on the phone [settings][app manager][installed apps]

the extreme ways to get ur phone memory back as like a new one is to re-flash ur device or re-update it. but it'll cause all of ur phone memory (included contacts, task, note, calendar, messages) lost. backup first.
