Hello, I plan to switch from T-Mobile to Sprint after being with T-Mobile for almost 10 years. The 2 main reasons I'm looking to switch from T-Mobile to Sprint, is that Sprint is the only other provider that offer native WiFi calling (not Skype, etc) and also have a much better 4G network. That being said, I have been using Samsung phones for the past few years and love them (although I really haven't used anything else besides these 2 models and a Blackberry) - first was the Galaxy SII and now the Note 3. I see that Sprint offer the Note 3 and Note 4 as well as the Note Edge, the Nexus 6, LG G Flex, and other Phablet phones. My question is this (I know this question has been asked a million times before), of the Phablet phones offered by Sprint, are there any better or recommended models for someone like myself who would like to 'root' them, or even install a custom ROM? (on my Note 3, I only rooted it, but was looking at installing a custom ROM to mainly get rid of all the bloatware). I see that some forums recommend 'not' going with Samsung because of Knox concerns when rooting. Thanks in advance!
