My phone keeps saying that the device memory is full and I can't save anything else. I have many important things I need to do and save on my phone. But I can't do anything if the memory is full. I already bought a SD card with a lot more space, but it doesn't help because I can't figure out how to transfer everything that is saved on my phone's memory to my SD card. I have a lot of important work and important files that I've saved there and really need them saved to my SD card asap. Please help. :(
