ASUS ZenFone 5Z (ZS620KL-S845-6G64G) - 6.2” FHD+ 2160x1080 display - 6GB RAM - 64GB storage - LTE Unlocked Dual SIM Cell Phone - US Warranty - Midnight Blue

I've had a great experience with every feature of this phone. I love ZenUI on this phone, it's light and snappy. The snapdragon 845 in this phone won't let you down with performance. As for connectivity, this phone has a great LTE antenna (4x4 MIMO) I get a stable LTE connection where my previous phone wouldn't even detect the network. I use AT&T in both the US and Mexico. Along with this, I absolutely love that this phone's dual sims BOTH support LTE connectivity. Switching LTE data between my SIMs is merely a menu setting instead of having to swap the sims between the slots. The camera works great. I'm no photographer, but the pictures look every bit as good as the galaxy s9+ to me. It's also extremely nice having having the wide angle lens for scenes that just don't fit into the regular lens. The full hd IPS display has a full, vivid range of colors and it's bright enough to view outdoors in the sun. I've heard a lot of negative things about IPS vs AMOLED, but consider this.. IPS has no screen burn-in, (I've seen really bad burn in on the S5 for example), IPS is brighter, and it is also far cheaper. I'd rather not pay a large premium for a screen that just isn't noticeably better. Regarding review on the lack of Tmobile VoLTE and wifi calling, why even use legacy voice networks when you can use a VOIP service like TextNow and stick to wifi/data? VOIP is portable, it can be used on any device and is not bound to any hardware or a sim card. VOIP services typically have unlimited texting and calling over wifi with cheap to free international calling. Also instead of wifi, it can also be used over any type of network (including LTE and even 5G when it rolls out) so techinally VOIP can use VoLTE on any phone that supports LTE data. The battery life is great, a full charge can get me through almost 2 days moderate usage and I leave LTE data or wifi on all the time. It charges very fast with the included quick charge. Overall my experience has been great with this phone!

Make no doubt, this is a flagship phone. Has pretty much top specs all over. Ive been using it as my main phone since late October and I have no plans to change. Im on Tmobile USA and it works pretty much great with it except no Volte and no Vowifi. I don't understand why OnePlus can get that to work but Asus can't because those are almost must-haves nowadays. But it is fast and responsive. Moreover it is relatively lightweight which I was surprised to find I very much like after using heavier phones. Even though I prefer Amoled displays I must say this is a very nice LCD. Colors to me are great. Nice sharp detailed look to everything. And it is more responsive to touch and swipes etc than any other device I own. The camera is the best Ive had on a phone. Great in low light. Doesnt overprocess like some phones do. Easy A grade for the camera. And one of the big reasons I got it was the speakers. They sound excellent. I listen to online radio lots and lots through the day. Really impressive loudness and richness for phone speakers. Another easy A grade. The software is well done with good Asus apps. Nice options. No complaints there. I'm hoping the Zenfone 6Z has Volte, Vowifi, a slightly bigger Amoled screen and all the rest it currently has. Just a fantastic seemingly underappreciate phone. 4.8 stars. Edit March 2019: Still really enjoying this phone. Although I take back that I would want a bigger screen. This screen is the perfect size. Had a chance to try out larger phones and Asus really nailed it with the screen size, screen ratio, and overall size/weight of this phone. It really is the ideal form factor. Big enough to enjoy watching vids and surfing yet still pocketable. And the weight is just amazingly light. Now if they switch to Amoled screen and get wifi calling and Volte on TMobile it would be the ideal phone.

So far, I love everything from this phone. Speed, Battery, Camera, Storage, Interface (UX), Customizations (settings), Looks, etc. If I had to put a negative though, it would be that the keyboard buttons are a bit too narrow for my fingers, but I just need to get used to it since I came from a Nexus 6, which was a bit wider. Overall, too good for its price :D

This device is very nice. I have not had any issues getting through the day on battery. The dual speakers leave a lot to be desired at maximum volumes. It becomes very distorted at higher volumes. I usually listen to YouTube videos at around 50% volume which sounds great and is plenty loud. I personally prefer LCD IPS over AMOLED for peace of mind when it comes to screen burn-in. The screen gets bright, but my OnePlus 6 has a brighter screen. I have no issues with the screen color or viewing angles. The device is incredibly smooth and the OS is well optimized. The signal propagation is strong, and I mean very strong. In areas where my OP6 and Galaxy S8 struggle, the Zenfone 5z will maintain a much stronger connection. I'm on T-Mobile USA for the record. The issue however is this device does not support T-Mobile VoLTE despite Amazon Q/A stating it does. As a result, in areas where t-mobile offers only Band 12 LTE as coverage, you will not be able to make phone calls. This is only in very rural areas but it is something to take note of. This device also does not support T-Mobiles newest LTE band, band 71. This is still in early rollout stages but for the longevity of the device, it may become outdated as more markets get Band 71 rolled out. Anyways, the device will drop down to HSPA (3G) to perform the call. Call quality is good, but I would've preferred VoLTE work out of the box. This device is not provisioned by T-Mobile or Asus to support VoLTE. I will attach a debug screen with personal information cropped out if you're interested. Without VoLTE or any plans from the company to rollout an OTA to enable it, this device will likely be going back. I do hope the manufacturer can respond and clarify why the device does not work with VoLTE.
