Off late I get message often indicating that my phone memory is low especially if I try to install some new app. I tried as much as possible to move apps which can be movable to SD Card. Is there something I can do to free more memory that is the phone memory. Also I remember someone suggesting decrapify your android. Is this similar to rooting. Kindly help. Also currently have 2 GB Memory card. Is it ok if I upgrade to larger size. Heard stories saying phone goes slow if we increase the memory via SD Card.
