While the more powerful Galaxy Alpha had a somewhat watered down version of TouchWhiz, the Mega 2 seems to be running the same version as the S5, and the weaker processor and 1.5GB of RAM in the Mega 2 simply cannot provide enough power to smoothly run the TouchWhiz software

It has great battery power

the Mega 2 is a decently spec'd phone that should serve most users well when it comes to browsing the web, taking photo's, watching videos, and sending emails, however the phone is not suited to play the most demanding games, nor will it suit power users who like to have many apps open at the same time
