Hello guys, I am using this phone from last December. Initially, it perform quite well, but now my phone becomes very slow, some time it take minutes to open an application or any open app does stop responding. I have installed lookout antivirus, current free RAM is 62MB,ROM is 73MB, I have 8Gb mem card which is 2.30Gb free. I think it is due to many files on the card. Is there any way of finding the unused files that is on the card. like for some apps we have to download additional files which saves on mem card. And later, after uninstalling those app, the corresponding files are still in the mem card. Thank You.
