only because it's dual pixel so it twices the resolution? what a stupid marketing. even bragging about large resolution itself is already a stupid thing.
All these Chinese OEM have become so untrustworthy with all the lies they disseminate in the name of Marketing. I becoming afraid of buying any of their smartphones.
In that case Z1 is definitely better than Z1i. Cheaper and using SD660. The chipset trade off is not worth it. You simply paying more for Z1i just because of the 128gb storage and a better selfie cam.
$240 with a 128GB on-board storage? Cool!
It's nice to see manufacturers make cheaper phones with very huge ROM storage these days. Kudos to Vivo!
