ram expander using your sdcard? siguraduhin mo na hi-quality yang memory card mo kung hindi no effect yan at dapat half swap hindi ka rin pwedeng tumaas, kung ang cp mo ay may 1gb ram with actual size of 800mb ram 400mb of sdcard lang ang pwede mo gamitin sa swap, if you don't understand what ramexpander is better forget about it, 50-50% chance to really make it possible to run. kahit nga yung mamahalin na cellphone na may 3gb ram naglalag sa apps yan pang extended ram using an sdcard. bili ka na lang ts ng magandang klase ng cp or root your phone and uninstall all bloatwares and unroot, if you want to play moba games in low quality phones just install the play games and moba games no other apps like fb, messenger, browser, to conserve your ram.
