>I really can't put what I want on my Android phone.
To be fair, that is only valid at face value. Yes, you yourself might not be able to do that technically, but it is quite easy and flat out possible compared to an iPhone.
Not on many (most?) Android phones. Samsung, Motorola, and LG devices still require many hoops to jump through if it's possible at all. Not all manufacturers are as open to rooting as OnePlus.
