I have that phone and I don’t have any problems so far except a little lagging but the store says the LG g4 stylus, & LG G stylo are the same phone. it comes with snapdragon 610, 410 is for entry level only. In my opinion this phone is not good because in this range many company provided 2 and 3 gb ram easily and digital dolby sound also.
This phone now has an update to lollipop 5.1.1. Be aware that it locks the bootloader, so all you root users should know.
