In that case, what I do is transfer all the apps I can to SD card. To do this, you Open Settings > Apps, under downloaded, check the apps installed. If the app is movable to SD card, you should see "Move to SD card" under clear data.

You're probably running out of phone memory, so please check my suggestion above. :)

Thank you Carl it's working....Thanks a lot

And One more question please...

I have 5GB free space for my mobile... but once i download the any apps its not install my phone. the Message will come insufficient space on your device...

My default storage place is SD card....

Whats the problem please let me know....

Hi there. Make sure your contacts are not saved on the SIM card, 'cause it's not possible to set contact photo if it is saved there.

Open Contacts > tap the photo beside a contact > a window will pop-up, tap the upper part of the window > Press menu key (left soft touch key) > tap Edit.
Now you should see a box where a photo should be, tap it and then choose how to add photo: Take a photo or Choose photo from Gallery.

Let me know if that works for you.
