sprint will always give you TP2's if you insist on the same replacement.
Like in a case I had a few years back, where they offered to switch my apache for a mogul before; unfortunately, I wasnt fond of the input lag and bluetooth bug and asked for a replacement apache. Lucky for me, they were able to source one even though they had been EoL'ed for over two years.
Anyway, if you believe its hardware related, bring it in
