The mini feels spectacular in hand, it is really awesome in that regard. Just like
@jav6454 said, it feels almost like an iPhone 5/5S.
The problem that made me return it -which I hated- is the OLED and the PMW and the headaches it gave me that screen. My eyes were red and sore, and I couldn’t stand it. Maybe it wasn’t the phone’s fault, that’s why I plan on giving it another chance in November, when the Christmas returning period starts. That way, I’ll have more time to test it and see if my eyes have a problem with current OLED technology or not.
Another problem I had with OLED was the color temperature of the screen and the color shift when moving the device and changing the vision angle, but I guess that’s unavoidable until Apple starts using QD-OLED on their iPhones. QD-OLED have better vision angles, and are flickering free screens. That could be the answer to my problems, so maybe I’ll have to wait until iPhones get those screens… Sadly, it is unlikely that Apple will release a new iPhone mini in the future with all this new technology.
But for those that can tolerate current OLED screens, yeah, the 13 mini is really an awesome device that feels super handy and comfortable on hand, just like in the old days, when you were able to reach all the screen with your thumb. Good old days.
