1. Q: Does the Xiaomi Watch S3 screen have slight color deviation when displayed at low brightness?
A: Based on the inherent characteristics of current OLED materials, the RGB three-color turn-on voltage is different. When the screen is displayed at low brightness, there will be slight color deviation, which will disappear when the brightness increases. This is a normal phenomenon, so please rest assured when using it.

A: To achieve the detachable bezel function, the cover plate has been chamfered and polished and observed in a specific perspective (staring at the gap between the Deco and the screen, observing it at approximately 60°/70° ). Due to the refraction of light, there may be light leakage between the side cover plate and the watch ring, which is a normal phenomenon. Please use it with confidence.

3. Q: How to deal with the uneven screen color issue on the pairing interface during the first startup of Xiaomi Watch S3?

2. Q: Can Xiaomi Watch S3 display heart rate when not being worn?
A: When you are not wearing the watch, enter the watch heart rate application and the real-time heart rate will not be displayed. You can view the historical heart rate and resting heart rate.
Note:
1. Support watch faces that display heart rate data. The heart rate is displayed as 0 when not worn;
2. In some cases, due to the heart rate judgment mechanism, the heart rate may be displayed when the watch is placed on some dark surfaces.

3. Q: Why is the heart rate test data of Xiaomi Watch S3 inaccurate, sometimes very high, sometimes very low, rising and falling?
A: Inaccurate heart rate measurement may be caused by wearing style, skin color, hair, reduced blood perfusion, low temperature, vasoconstriction, or dirt or water stains between the watch and wrist;
To ensure measurement accuracy, please wear it tightly, keep the device from sliding down when your arm is shaking, and wear the device one finger above the wrist bone.
For cold weather conditions, due to the influence of low temperature, the capillaries of the human body's extremities shrink, and blood flows back to the trunk and organs, making it more difficult to obtain photoelectric heart rate signals at the wrist, and it is also easier to lose the true heart rate signal during exercise. Therefore, it is recommended to fully warm up before exercise to speed up the blood flow and facilitate the sensor to obtain more accurate heart rate data.
Please ensure that the bottom case of the watch is clean and dry, the temperature of the watch is not too low or too high, there is no sweat or foreign matter on the wrist, and it must be worn comfortably and snugly;
At the same time, engineers are also trying their best to optimize the solution. Please wait for subsequent upgrades and updates.

4. Q: How to deal with the inaccurate blood oxygen test data of Xiaomi Watch S3?
A: It can be caused by the wearing style, skin color, hair, reduced blood perfusion, vasoconstriction at low temperatures, or dirt or water stains between the watch and the wrist. Restart measurement according to the blood oxygen instructions.
Factors such as wearing status, skin characteristics, environment, etc. may affect test accuracy or even measurement failure. This product is not a medical device and the results are for reference only and are not used as a basis for diagnosis and treatment.
Measurement instructions: 1. Wear the device to one finger distance from the wrist bone;
2. Wear it tightly and keep still during the measurement.
At the same time, Engineers are also trying to optimize the solution. Please wait for subsequent upgrades and updates.


5. Q: What to do if Xiaomi Watch S3 fails to measure blood oxygen? 
A: First check whether the protective film on the back case has been removed. If it has been removed, re-wear the watch according to the measurement failure prompt and continue measuring blood oxygen;
Turn off all-day blood oxygen monitoring, tap on the watch blood oxygen application, and measure blood oxygen once. While the watch is measuring, check whether the blood oxygen light at the bottom of the watch will light up. If it does not light up, you can unbind, rebind, or restart. If the watch is still invalid, you can apply for after-sales inspection.
Note:
The back case of the watch is shipped with a back case protective film to prevent wear and tear during transportation; low oxygen and heart rate measurements rely on the sensing of the back case;
When using the device, you need to tear off the protective film before you can use the blood oxygen, heart rate and other detection functions normally. Failure to tear it apart will prevent the sensor's light from contacting the skin of the wrist, resulting in no measurement or value being obtained.

6. Q: Why are there multiple low blood oxygen levels when the watch turns on the all-day blood oxygen function and when you wear the watch to sleep, the blood oxygen value appears during sleep/single measurement?
A: 1. You can have blood oxygen levels lower than 90% when sleeping;
2. Try to ensure it fits your wrist as much as possible when wearing it;

eSIM related
1. Q: How to use the Xiaomi Watch S3 eSIM version?
A: Due to the adjustment of the operator's business policy, communication for some of the operator's eSIM services online and offline is currently suspended. For specific business resumption times, you can contact the corresponding operator's customer service, and the operator's reply shall prevail. The problem of not being able to activate eSIM is not a watch hardware failure. We are also actively contacting the operator to assist in processing, and we recommend that you wait patiently for subsequent operator recovery.

2. Q: What are one-number dual-terminal and independent numbers on the Xiaomi Watch S3?
A: The eSIM one-number dual-terminal service means that the additional card activated on the watch that supports the eSIM function shares the same number with the main card of the mobile phone, sharing voice and data packages, etc. The watch can independently use data and make and receive calls, but it does not support text messages and international roaming services.

It is not a watch hardware failure. We will continue to optimize and improve the function of one-number dual terminals with operators as soon as possible.

4. Q: Why can’t the Xiaomi Watch S3 eSIM version check the EID information on the App in addition to checking it in the box?
A: This bug has been fixed in the latest firmware version of the watch. Please tap [Check for Updates] at the bottom of the Mi Fitness App device page, update the watch to the latest firmware version and try again.

Troubleshooting
1. Q: What to do if the Xiaomi Watch S3’s step counting is inaccurate?
A: The principle of step counting:
The watch has a built-in acceleration sensor. The data detected by the acceleration sensor is then combined with the algorithm and the basic information of the human body, and finally converts this information into information such as the number of steps and consumption;
Factors affecting the number of steps recorded by the watch:
1. Because the principle of measuring the walking distance of the watch is to estimate your step length based on the height, gender and weight set by yourself, and then multiply it by the number of steps taken by the individual to obtain an estimated value.
2. Because the step length varies from person to person, people with the same height, gender, and weight may also have different step lengths, so the final calculated value will also have a large error;
3. The accuracy of step counting, that is, the number of steps taken, also has many uncertain factors that will have a great relationship with everyone's behavior habits, such as the walking habit of waving arms, etc. (such as walking, riding, driving, bathing, etc.), and arm movements are more complicated (such as keyboard tApping, moving the mouse, lifting and pulling objects, etc.);
4. It is precisely because of the above reasons that the final calculated distance of the watch is also an estimated value, and the watch cannot be used as a professional measuring tool to measure the distance. We will continue to optimize the software algorithm to calculate more accurate data.
Note:
The watch will update the step count multiple times every minute, but it will not update the step count in real-time every second.
2. Q: What to do if sometimes the GPS positioning of Xiaomi Watch S3 is slow?
A: The troubleshooting is as follows:
1. Please make sure you are exercising outdoors. When the surrounding environment is complex (high buildings, lakes, etc.), positioning will be slightly slower. It is recommended to restart positioning in an open environment;
2. If it has been a long time since the last outdoor exercise, the ephemeris data may have expired. It is recommended to open the [Mi Fitness] App, reconnect the watch and refresh it synchronously, which will improve the GPS positioning speed;
3. In indoor, underground, tunnel, indoor swimming pool, indoor stadium and other environments, the watch is currently unable to perform positioning.

3. Q: What to do if the Xiaomi Watch S3 still displays pace information when I stop exercising in exercise mode?
A: The mileage and pace during exercise require time to be calculated and determined. The pace will not stop until 10 seconds after stopping exercise (completely stationary).

17. Q: Why can I see equal stripes on the screen at certain angles and why can I feel the screen is grainy in low-brightness usage scenarios?
A: Xiaomi Watch S3 uses an AMOLED screen. There is a very thin film material in the polarizer stack. The thinner the film material, the thin film material will shrink in the direction perpendicular to the stretching direction when it extends, and it will stick to the base material. The tendon-like traces left after closing are inevitable. Please feel free to use them. The luminous brightness of different pixels on the display screen is different, resulting in macroscopic differences in brightness at different locations. The human eye is more likely to detect the difference under low brightness. This phenomenon is inevitable, so please feel free to use it.

18. Q: Why does my Xiaomi Watch S3 fail when opening/recharging/checking a card?
A: 1. The operation failed due to network reasons. You can switch to another network and tap [Retry] below the card activation failure prompt;
2. Since some mobile phones have built-in NFC modules, if the watch is too close to the mobile phone, the NFC writing channel of the watch will be occupied and cause failure. It is recommended to turn off the NFC function of the mobile phone or move the watch more than 10CM away from the mobile phone;
3. Restart the mobile phone's Bluetooth, switch the mobile phone network and try again;
4. Terminate the phone process, make sure the connection between the watch and the phone is normal, and try after recharging the Mi Fitness App;
