[OnePlus 5 Questions & Answers] Ascertion:
I'll break up a short review into a few sections.

Design - 9/10

I really like the build quality. The phone looks very similar to a certain device, but I don't mind this. The matte black color looks great and the device, while a bit thin, is the perfect weight (although I am going to buy a case as soon as they become available.) Although I do wish the camera was in the center because when you lay the device down, the protruding camera lens is what your device lays on and makes the device not lay completely flat. The good news is the camera lends is made out of sapphire so durability is there.

Performance | Daily Tasks - 9/10

I have read all about the "Jello effect." This does appear on my device, but it's very minimal and I don't see it as a problem. I did recently watch a video where it was a lot worse in that video. People on social media tend to be hive-mind associated so a lot of negativity tends to spread like wildfire while the positive items are left out of the spotlight. I think the device is extremely snappy and I have noticed the phone doesn't even get warm while playing Pokemon Go for long spurts at a time. No sluggish performance at all.

Wireless Connectivity | WiFi | 4G - 8/10

Cellular Performance

This aspect is generally very important to me. When I compare it to my brother's GS8 on T-Mobile US, we both have a consistent experience in strong signal areas. The OP5 doesn't support 4x4 MIMO on the 4G/LTE side, but it does support 256QAM and 3xCA which is more than enough for the typical power user. Overall, my brother's S8 tends to get slightly less than 10% more speeds on LTE than I do (for comparison, I hit 115Mbps in a spot whereas the GS8 hit 125Mbps.) However, I will note that edge-of-signal, the S8 does win outright. In a few areas where LTE signal is weak (sub -120dBm RSRP), the OnePlus 5 will tend to drop to HSPA or even Edge whereas the S8 will maintain a usable signal. In other words, VoLTE'ers, you may experience more dropped calls when venturing about in weak LTE areas.

WiFi Performance

The OP5 supports 2x2 MIMO and wireless AC so 5Ghz networks is vastly improved over the OP3/OP3T in regards to WiFi coverage/performance. In comparison, I can pull up to 540mbps in a corner of my house on the OP5 whereas the OP3T will only be able to pull 32mbps on the same network. Oneplus has really went above and beyond in terms of WiFi antenna design and has consistently matched the GS8's WiFi performance (Note: I do not have Gigabit internet so I wan't able to test higher-end speeds.)

Battery - 9/10

I am coming from a Le Pro3 (which is one of the best devices for battery), and I'm not too concerned with what I'm getting on the OP5. I am consistently getting through the typical work-day with around 30-40% juice left after a few hours of screen time. If I need a quick charge, Dash charging is there. I will mention that I wish Dash Charging wasn't so proprietary. Because almost all of my current chargers are Qualcomm QC which aren't compatible with the Oneplus. Although it'll still charge the device, just not rapidly like Dash would.

Camera - 7/10

I am not a photographer by any means and a good camera doesn't necessarily sell me on a device by itself. I will say though that while the pictures are not as good as what you'd get on the GS8, they are pretty good shots and I honestly can't see people looking at your facebook pictures and thinking "wow, whatever camera took this picture sucks." I am quite content with the camera because it is better than a mid-range device, but worse than a flagship.

Software/Customization - 10/10

This is the main reason I went with the OnePlus device. Oxygen OS is so smooth and AOSP-like. The nearly bloatless experience and ability to change the theme/accents of your device are amazing. That, and I know the community will be behind some massive developments for this device so I can satisfy my flashing urges as they come up. It all just works.

Sound/Speakers - 9/10

I would have preferred stereo speaker setup, instead of mono speaker. Still, I would say I have been very impressed with the mono speaker on the bottom with the amount of quality and loud sounds that come from it. Music in the car over Bluetooth/Android Auto also works great and is very clear sounding. I actually flashed the Viper/Arise sound mod and disabled it shortly after because stock sounds that good (I don't play around with the Viper/Arise settings too much, so maybe I can improve it but to me there's not much left to be desired.) Voice Calls, people are loud and clear.

Overall, I am very happy with my purchase and would recommend the product to a friend!
