I ended up keeping my LG G2 for four years. It was just too slow to keep using for data. It was hard to get myself to the store and buy another expensive phone at full price.
I finally went to the Sprint store to see what phones were out and get a feel for them in person rather than just listen to people on YouTube talk about features I don't care about and never use.
Apparently Sprint was having a one day "sale" for current customers. I don't like leasing phones, I prefer to buy, in fact, I will only buy, not lease. For this "sale", I have to make payments and then get the option to buy the phone at 18 months. In the end, it is a 0% interest payment plan with a manageable balloon payment at the end and I will get about $200 off the total cost of the phone.
As you can see above, I got a Samsung Galaxy Note 8. I figure this will last me for a while and so far it is way faster than my old phone.
