Hi,

I am currently flying with a Galaxy J5 with 2G RAM and 8 cores.

I could get my hands on an iPhone6, wondering if that would perform any better?

Does the use of IOS have benefits?

I'm in Europe.

Thanks!

Hi thanks for reaching for DJI Forum, we do apologize if you had problems with your mobile device. If you are planning to buy an iPhone6 , yes its fully compatible to run the app. Benefits are still the same as long as its updated for their respective versions. Thank You.

From reading several threads on here it certainly seems like iPhones perform much better with the Spark than Androids.  I've used two different iPhones (6 and 6s) and an iPad Mini 2 and have never had any of the issues I read about on here.
