ASUS Zenfone 5 Raw Impressions (Pre-Production Unit)

During a special session for the media and tech bloggers, I’ve been given the opportunity to test out the newest Zenfone 5 unit that was announced during the ASUS screen time during the World Mobile Congress 2018.

The special session allowed us to take a first shot on the pre-production unit and here’s a few impressions I’ve had for the unit.

Before everything else though, here’s the first look at the front side of the Zenfone 5

Raw Impressions

One of the things that’s pretty noticeable with the Zenfone 5 design is the bigger screen the phone has. Unlike it’s predecessors the new Zenfone is able to maximize the screen. There is lesser wasted space compared to it’s predecessors which is a great update especially with a lot of the other brands already taking the same screen landscape philosophy.

Meanwhile, the back panel of the phone is still a fingerprint magnet, similar to the premium Zenfone 3 lines.

So far the pre-prod build we had felt solid enough but also at the same time, luxurious enough just like the higher end phone lines. The camera isn’t as great especially with the more selfie centric phones, but then, it seems like the Zenfone 5 was made to not that have in mind.

I must say though that the Zenfone 5 is back, and it’s better than ever.
