terribly optimized for or purposely programmed to suck on a 6 prolly bc they want you to buy the 7
my friend, after 2 weeks and a $200 deductible on a repair plan, got his 6s back, but now it opens up random apps and won't even register input on the touchscreen half the time. they're sending him a new one but i predict it will run slow af within a month of ownership
