Custom ROMs have always proved to be a blessing for the Android smartphones that have been forgotten by the manufacturers in the software aspects. The reason for manufacturers to stop the software updates is the limitation of hardware. Old hardware is not capable enough to run the latest softwares all the time. Thus, to keep the device’s software intact, device manufacturers keep it to a certain version of OS and then discontinue its software support. One such unlucky device is Samsung’s Galaxy Mega I9152, It couldn’t see any further version of Android after Android 4.2.2 Jelly Bean. Galaxy Mega enjoyed the latest versions of Android by means of custom ROMs, so that’s how this device comes under the umbrella of blessings we just talked about a minute ago.
