very good
This phone is very nice with night vision, thermal camera, nice screen, very fast. However at the first time using it in in wet condition, some water came inside the standard camera lens, camera is no more unusable because of dust inside the lens, very disappointed, i missed a lots of nice pictures during holliday! I hope customer service is efficient and will repair that.
Looking good.Hope it will long lasting
I already have it for more than a month. It is much better than my previous rugged phone. The only thing that I don't want is that it was consuming 25% of its battery when I didn't use for 24hrs. Yet overall on this unit is all goods. Thank you phonemax for great product
Just what I want.... Great!
Nice phone .thank you phonemax 🤩
So cool
Looking forward to seeing you again

I received the phone yesterday and was very excited. I couldn't wait to test the thermal imaging function of the phone. It was very good. I could capture the stripes of the tiger in the video. This made me very happy to buy this R4GT. I will pay close attention to all products in the phonemax mall and repurchase
Phonemax R4 GT is awesome. I love that the thermal imaging is the same as in the video, which means a lot to me, I can use it to detect unknown objects at night
Yesterday I received the package, very nice phone, the perfect smartphone for my shirt pocket. Small, delicate, but powerful and easy to use.
Is ok. The camera did not with that great
Love the size and feel in the hand. It does everything i need.
My only criticisms are that the photos on the website misrepresent the actual screen area, and some of the bloatware can't be removed (when I don't know what some of it even does, I don't want to agree to T&Cs)
Overall I'm very happy with it, and would be reluctant to go back to a 6 inch+ phone.
US buyer. Ship time was as advertised. Shipped from Shenzhen. Great device.
Great phone thanks!
Very neat and features-packed smartphone. Quick delivery. Very smooth process overall. :)
The phone is great, fast, has the features I wanted, the only downside is that I can't find a protective film in Europe.
Nice phone with pretty good camera and screen, but with some downsides: no fingerprint sensor, buttons hard to press, battery not too good.
Small, fast and beautiful.
Great little phone
Just arrived, can't really say too much, yet.
It's tiny!
Nice little phone
PRODUCT QUESTIONS
Frequently asked questions
What is the difference between thermal imaging and night vision on the R4 GT?
Thermal imaging visualizes temperature differences, while night vision captures visible scene detail in darkness using infrared assistance. The two functions support different inspection, search and outdoor tasks.
Who is the Phonemax R4 GT designed for?
The R4 GT is designed for technicians, inspectors, outdoor users and professionals who want thermal imaging and night vision in a compact rugged smartphone.
How compact is the R4 GT?
The R4 GT measures approximately 121 × 59.2 × 18.3mm and weighs about 190g, giving it a much smaller footprint than many thermal-imaging rugged phones.
Will the R4 GT work with my carrier?
The R4 GT supports a broad range of 4G bands, but no phone is guaranteed to work with every carrier. Compare the product band list with your operator’s frequencies before purchase.
Can the R4 GT replace a professional thermal camera?
The integrated thermal camera is useful for convenient inspections and temperature-pattern detection. For regulated, calibrated or safety-critical measurements, use certified professional equipment suitable for the application.
