[T-Mobile Samsung Galaxy S7 Edge Questions & Answer] sshafranko:
Some good info here and I couldn't help myself feeling the same disappointment as most looking for S7 root. I don't own 1 my wife does, personally I'm a Note user since the beginning, but this situation opened my eyes to what's coming for the Note 6 and the future of Samsung. To sum it up I believe Samsung S and probably Note series at least, will be locked up as the S7 is now. I have tried my best to open my mind to new phones such as Nexus for my next update, if the Note6 is locked, at the very least ill keep my Note 5 for another year.

Since I saw the question "WHY" mentioned a few times reading through this thread I'm going to give you my opinion backed up with some photos of stats and such, as to why I think is the main reason for Sammys gradual lock down practices.

WARNING: I admit this may sound a bit conspiracy theorish, but you are free to your opinion in this country, at least for now. Ive mentioned this before in other threads but ill go a bit more in depth here and with pics.

My belief is that Samsung is trying to take over the government cell phone, tablet, printer, etc.. sector, owned by Blackberry in the past and knox was originaly created for this but rolled out and tested by the "businessman" sector. With over 20 Million US government employees, yes 20 million, the petition started by ice which I signed and is up to about 2,300 signers, is an ant in the grand scheme of things and will be brushed aside. Where did the lock down start? Verizon = the biggest carrier most likely with the government contracts already. (Conspiracy Theory: Maybe TMO wants in on this government contract race and is totally OK with the locks) Now 20 million phones in US, how about all the other countries in the world? how many phones does that equate to? You can search and read a lot more on this subject if your interested and you will find some interesting things, for example Google makes a separate version of Android for the governmet.

If this is all true I think our only chance in the future is if they make a Dev addition phone for us 5, 10 thousand maybe rooters who want to play with our phones. Bottom line is, in the end, its all about the $$$ and the scale is greatly tipped against us. I'm not saying lay down and take the beating, I want to customize and mess with my phone just as much as everyone here, and yes you paid for it and you should have a say in what it does and how it looks, but at the end of the day Samsung will decide what your phone does and they can. What you can do is not buy Samsung, but don't fool yourself, buy voting with your wallet don't think that our little numbers will even chip Samsung's bottom line.

Now this might be a bit more far fetched than my government theory, but I have a feeling Samsung will eventually leave Android all together and adopt their own OS maybe Tizen? Just a hunch but like I said my mind is slowly opening to the view of me, holding my Nexus phone, and rushing home to flash the new release of Pure Nexus Rom...;)

Edit: just realized the S7 in the pick Att...so there you go. Verizon and Att probably holding the contracts for us government, is it coincidence they locked up a while back and now Tmo is?
