verykool SL5000 Quantum 4G LTE Android Smartphone First Impressions

The verykool SL5000 is one of the latest Android smartphone models that has been released by San Diego based InfoSonics. What makes this device stand out from its other offering is that this is the company’s first ever 4G LTE smartphone. Aside from its fast connectivity feature this model already runs on Android 4.4 KitKat, has a 5-inch IPS LCD display, and is sold unlocked which means that it can be used in any GSM network around the world.

I was able to get my hands on a unit and used it as my main driver for a week. Below are my impressions of the device.

Inside the box you will find the usual stuff that you get when you buy a phone. There’s the unit itself, a battery, earphones, USB cord, wall charger, screen protector, and the manuals.

The SL5000 Quantum closely resembles the company’s previously released model called the s505 Spark (which we did a review of). Upon closer inspection you will see that there are differences. The front of this 4G LTE model has three capacitive buttons while at the back the rear camera centrally located. The s505 Spark on the other hand has its buttons placed on the display itself and its rear camera is positioned at the left back side.

The first time you hold the SL5000 Quantum you will immediately feel that it is solidly built as there are no creaks even if you hold it tightly. It has a nice feel with its metallic sides and plastic front and back. Despite being made mostly of plastic it does not feel cheap at all. The back portion though is glossy making it a fingerprint magnet.

Since this is an unlocked model you can insert any GSM SIM on it. It would be much better if your network has 4G LTE service so you can take advantage of the fast mobile Internet speed. On paper, you should be able to get 150Mbps download speed while your upload speed is going to be 50 Mbps. This speed will be dependent on what your network is offering.

Checking on the AnTuTu benchmark results this model gives a score of 17823 which is already a decent value for a mid-range smartphone. I’ve tested several apps on the device and even some graphically intensive games and it performs well. There’s no noticeable lag that would make the device difficult to use.


One thing I’d like to mention is that I’m impressed with the included in-ear headphones. They are beautifully designed and the sound that they produce are amazing. I’m no audiophile but these headphones sound better than the included headphones of other major Android brands.

For those who love taking photos there’s an 8MP rear camera with auto focus and LED flash that takes good photos. If you’re into taking selfies or placing video calls then the 2MP front camera will prove to be useful.

Overall I’d say that the verykool SL5000 Quantum is one of the best 4G LTE smartphones out in the market today considering the fact that it only costs $230 and you won’t get tied down to a two year contract.
