From the table and list above, ASUS did improve a lot of aspects for the new Zenfone 3 but what’s noticeably unchanged is the screen size which probably because they have the Deluxe and Ultra versions for those who want a bigger display. The camera department also received an upgrade with larger megapixel count and better AF system. Also, the design language of the 3 is top-notch.
In a nutshell, Zenfone 3 is definitely a better smartphone and a good upgrade from its predecessor. It’s like having all the flagship features in a more affordable package. Check out our first impressions here.


Guys, I dunno but I hope Yugatech does have a proper comparison…. Maybe not based on spec sheets and a real freaking Comparison Article or better yet video… Oh, and you might want to check out the Huawei P9 Lite which would only cost about 12,490 and gizguide.com already hs a review about it.. The only downside I see against Zenfone 3 (base edition with 3GB RAM 32 GB Rom and 2600mAh batt) is no OIS and 16GB base storage… Other than that I think this would be a great clash between Midrangers
