Dial *#9900# and click on copy to sd card u increase lot of space in internal memory :)
I have a Prestigio PAP4044Duo with 4.1.1 Android on it. It has a Internal Memory of 786MB + Internal Memory Card of 1.77 GB. Since all the applications are stored on the Internal Memory I'm runing fast out of space on it.
I have HTC Pico (has 150 MB internal memory) and switched to ART running android 4.4.2. Now it has 11 MB free space with only user app as file manager.
I have deleted unwanted system apps (like gapps). Can we free up internal memory space without using memory increase script?
