Samsung Galaxy S7 could be released alongside a phone upgrade program (similar to Apple's iPhone upgrade plan)
Korean website ET News reports that Samsung intends to introduce a phone upgrade program in March. That's also when the company is expected to start selling its new Galaxy S7 family of smartphones (which should be announced at MWC 2016 in February), so S7 series buyers will likely be the first to benefit from the program.
Last year, Apple introduced its own handset upgrade program, allowing customers to get an iPhone 6s starting at $32.41 per month, and trade it in for a new iPhone each year, once new models are launched. Most probably, Samsung's upgrade program will be similar, asking users to pay a monthly fee for their Galaxy smartphone, while being able to get a new model year after year.
