Pls Help! My Phone Is Writing System Error:gallery (-20): Read Am Abeg

 Pls my dear nairalanders, my phone always writes "system error: gallary (-20), whenever i try to open my gallary, before now, sometimes after writing it twice or more, it will stil bring out my musics,video and photos and i wil now continue. But dis time around after writing the error message, nothing wil be seen in my gallary not evn 1 single item will be seen through my gallary, unless i use file manager to access my stuffs.B4 i thaught it was just an ordinary thing and i just ignored it since i ave an alternative, but now it has affected my call recorder and it cant record any call again, ave tried re-installing the app. but it wont work due to its part of the gallary(as a sound clip). Ave also formated my phone but it continues, am using Nokia 6680. Pls what can i do?Help

but ave formated my phone before, and i think that formating and flashing  are the same thing. or are they not? pls i nee your help nairalanders. thanks

bro i got the issue before with my N70. this problem can be rectified by formating the memory card. if u can copy the files in the memory card into a computer, then format the memory card using the phone. then copy the files back to the phone remember to enable showing of hidden files in the system so that you can copy both the applications too. formatting the phone will not solve your problem. it is the memory card that is the issue
