My moto x does have that grey-to-purple with low brightness effect as well. My note 3 has the same purple trail effect as my moto x, so I think the purple haze and grey-to-purple effects are due to the amoled panels they use.
I got a moto x, and I noticed that moving black objects have a purple haze effect. This Is actually similar to my aunt's S4. Is my moto x defective or is this just an amoled thing?
I am planning to purchase an off contract Verizon moto x off of the moto maker website. I know it will come with a pre installed sim but I would prefer to use my current nano sim. Am I required to activate the new sim or can I use my current sim?
