My mobile phones memory is low. why - Nokia N97 Cell Phone

I think you can use some apps with Boost feature. like LEO Privacy. It's the best free security app I ever downloaded, supper good for low memory phones.

LEO Privacy makes my phone fly. My phone always hang, because there are always some apps run in the background. One day I suddenly find in LEO Privacy there is a Boost, and then I always use it, and now my phone runs faster,LIKE it! LEO Privacy Applock Boost Hide Android Apps on Google Play

Hi, to free up some memory you need to do the following.
1, delete all messages in inbox, outbox,sent,drafts.
2, delete any pictures you dont need
3, delete any ring tones you dont use, most people never use the ones you get free with the phone so deleting these will free up loads of memory.

the reason your phone says low memory is because the memory card isnt counted in this low mem warning so you can transfer stuff to the memory card to free up memory on the phone.

you can also delete any contacts you dont need
