The Stylo 4 from boost and a real LG Stylo 4 are no more the same phone anymore than the Moto e5 Play is to the Moto e5 Plus. As such it needs a different name in the same manner (at least).
I had the Stylo 4 from MetroPCS but ported to boost before my 190 days to unlock it because I thought I was getting the same phone (and I thought I was getting a better phone for my wife).
There are so many features missing on boost's version it can hardly be called the same phone and shouldn't be named as such.
NFC Fast charging Face recognition WiFi calling VoLTE Slower processor (1.5 vs 1.8) Extreme amount of bloat ware
This is nothing short of a blatant lie and a slap in the face to the customers who expected a decent mid range phone as the carrot for their business. As soon as my month of service is over I will port out and my shadow will never darken the door of a Boost Mobile (or Sprint) store ever again.
The Stylo 3 on Boost had 720p resolution, whereas the Metro version had full 1080p. I had one promo phone from them that couldn't read QR codes out of the box and was a POS overall. Another one, the LG Volt, was advertised as having 1GB of Ram but came with even less than that, and within a year was having battery drain issues that made it unusable. I still used Boost but no way will I touch any phone that is made for them.
You can always look at the specs on the site. And yes Boost Mobile phones are cheaper because : specs are worse and the bloatware pushes down the price.
I have been an agent for 7+ years. The worst case was the Stylo 1. MetroPCS got 2gb of ram. And heaven forbid the Boost got 1 gb of RAM. I can't tell you how many pissed off customers I got lol cause 1gb of ram simply wasn't enough. That phone was laggy from the start.
