The strap is very nice in terms of quality. We had no trouble wearing the watch for an extended period of time, but you must find the right fit for your wrist or it may feel scratchy on your skin. Also, you can easily swap the strap for another one you prefer. If we had one complaint, it would be that the power/function button could have doubled as a digital crown, which would have improved the overall experience of the watch. The SpO2 and heart rate sensors, as well as two magnetic pins for quick charging, are located on the back of the watch.

The GTS 4 mini’s display is a slight improvement over its predecessor, the GTS 2 mini. The screen has grown from 1.55 to 1.65 inches in size, and the resolution has improved slightly. It’s still an AMOLED screen with the “Always on Display” feature. The display is by far one of the GTS 4 mini’s best features. It is sharp, vivid, and sufficiently bright to allow you to read the time outside in direct sunlight without having to adjust your sunglasses or use a light source other than your watch face.

The display on our test unit was not perfect. We felt that the clock was slow and did not respond smoothly to our touches/taps because the display does not refresh at 60 Hz. Furthermore, while the bezels around the display are somewhat thick, they do not detract from the overall experience because the deep AMOLED blacks blend well with the black borders.

Our watch had an always-on display that worked perfectly at first, but then it stopped turning off automatically at night. We even tried to turn it off completely, but it still stayed on. A factory reset fixed our problem in an instant. ..

The Amazfit GTS 4 mini is a great option for those looking for a Bluetooth 5.1-enabled smartwatch. Its connectivity was flawless, and the UI was smooth and responsive. ..

The 60 Hz display on our test model slowed down the watch and made it difficult to track activity. The most important aspect of a fitness watch is tracking activity, but the 60 Hz display on our test model made it difficult to do so. A future software update should fix this issue.
