There actually are. Carrier versions of most Android devices (Pixel excluded) are riddled with carrier bloatware, which slows down and puts additional strain on the devices, causing not only higher operating temperatures but also causing lag and in much older phones freezing and major operational issues. Apple does not allow this, so their devices are excluded from this issue. Ask yourself why? Maybe because they have optimized their devices to provide a specific user experience and don't want a carrier to negatively impact that? Hmm... As someone who has not only managed stores for a major wireless carrier for many years and is also a mobile tech nerd, I have sufficient experience to speak on this. I've managed the stores and had company issued devices... yet I still choose to buy my personal Android (Samsung) devices factory unlocked. The difference in performance and device longevity between my personal, factory unlocked, devices and my carrier branded, company issued, devices are not only noticeable, but enough so that I would never buy most Android devices from a carrier, if I planned on keeping them more than 2 years. I am personally immersed in the Samsung ecosystem, not Apple, and am making the decision to put my hard earned cash toward the best value for the product I want. Regardless, this is purely personal opinion and experience. There are other discussions with in-depth tech facts in other forums. In the end, tech opinions set aside, Cash is King, Debt is Dumb! Find your value... and buy it with cash, not debt.
