The Zeblaze Thor 4 dual is a standalone smartwatch running a full, but customized, Android 7.11 operating system. Users will have full access to the Google Play Store and the functions of a smartphone inside of a smartwatch. It has a 1.4″ S-AMOLED display at a resolution of 400*400.

Thor 4 Dual is the predecessor to the Zeblaze Thor 5 Dual which has a completely different design. Some may prefer Thor 4’s design over Thor 5 because it has a more classic watch design. Interestingly, the title “Dual” in both the Thor 4 and Thor 5 have two different meanings. With Thor 4, there are dual 5MP cameras while Thor 5 has dual processors and operating modes.

The Zeblaze Thor 4 Dual has a 5MP front-facing camera at the top of the watch where you would expect it. I’ve always thought side-facing cameras were useless and still do. However, being that the Thor 4 has a front-facing camera and a 5MP side-facing camera, it’s much more useful for taking pictures or video calling.

On the back, you’ll find the sim card slot, heart rate monitor, and the four-pin connection to charge the smartwatch and transfer data. Also, you’ll find the physical power and back buttons on the right side of the watch.

The Zeblaze Thor 4 Dual has a 1.4″ AMOLED display running at a resolution of 400*400, it’s a full touch display, and has Gorilla Glass 4 protection. The one thing missing from this model is the detachable bands since the antennas are inside and can’t be removed.

Zeblaze Thor 4 Cameras


The Thor 4 Dual runs the MediaTek 6739 processor at 1.25GHz with a 530mAH battery. This isn’t the MediaTek 6739 + NRF52840 dual processing unit on Thor 5 which gives the watch two operating modes. However, the battery on the Thor 5 is only 548mAH and it also runs at 1.25GHz, you won’t see much of a difference in performance.

The standby time of the Thor 4 is listed at 2 days and battery life will ultimately depend on how you use and optimize it. Since it’s supposed to be used as a standalone device and relies heavily on 4G, you should anticipate one and a half days of actual usage. Installing a lot of applications, especially social media apps, can decrease battery life considerably.


The Zeblaze Thor 4 Dual comes with 1GB of ram and 16GB of internal storage. These resources were standard when this watch was manufactured, and since then, most flagship devices like the Kospet Optimus Pro and Kospet Hope have 3GB of ram and 32GB of storage. Regardless, the Thor 4 Dual has enough resources to perform fluidly and you should have more than enough space for storage.

It will take some time to figure out the menus. Swiping up will take you to health data, left goes notifications, down goes to quick toggles, right goes to the app drawer, and right again to health applications. And, since it’s a modified Android operating system, you cannot change the widgets or add new ones.

Some applications don’t take advantage of the full display and this usually happens with apps installed from the Play Store. You’ll often need to use the built-in application adapter by holding down the “power button” and selecting the icon at the top of the screen. It changes the orientation of the app from a circle to a square, allowing you to see more of the application’s content. See the Janus & Lokmat X360 review for pictures of what this looks like.

Finally, there is no waterproof rating listed for the Thor 4 Dual. Typically, these smartwatches have a “Life Waterproof” rating which is basically IP67 rating. You should be ok with rain and sweat, but IP67 isn’t suitable for high-velocity water activities.


The Zeblaze Thor 4 Dual has a 4G LTE radio unlocked for any GSM carrier. Check the product pages to see if your area supports the bands. In the United States, T-mobile, AT&T, Cricket, and MetroPCS work fine but depending on the area, you might get LTE or 3G.

Bluetooth 4.0 is available for using headphones or sending and receiving files, however, there is no Bluetooth calling with any Android 7.1.1 devices due to Google’s restrictions. Maybe that will change when devices with newer Android versions are released. Right now, only devices with Android 5.0 have Bluetooth calling.

GPS works excellent with Google Maps, Uber, Yelp, etc, but not with the built-in fitness applications provided by Zeblaze. You’ll have to install Google Fit or wait until they push out an update. Most Android smartwatches have this issue so this isn’t a Zeblaze specific issue.

Zeblaze Thor 4 Health Apps

Fitness Applications

Android smartwatches come with their own fitness applications with activities such as Outdoor Running, Walking, Indoor Running, Bike Riding, and a few others. If you want to track your distance using GPS, the watch doesn’t use the pedometer instead of the GPS module. At some point, the manufacturer will push out an update to fix this. In the meantime, you can use Google Fit if you need GPS tracking.

Thor 4 Dual use the WiiWatch 2 companion app to pair with your smartwatch; however, pairing them restricts some of the smartwatch’s capabilities. You can receive notifications but can’t reply. The app is really only good for changing watch faces and viewing health data. There is an IOS version in case you have an iPhone, but the experience is worse than the Android version.


There is a 1-year warranty for manufacturer defects and you should check the product pages for all of the specs. You might also find the Full Android Watch forum helpful for tweaks, tricks, and to see what others in the community are doing with their full android smartwatches. Also, xda-developers also a great source of information for Android devices.
