Frequently Asked Questions (FAQs)

1. Why does the smart watch automatically disconnect/
unpair when the Android screen goes out?
Most Android devices have a battery saver feature to quit 
out of an app once you’re done using it, which can 
sometimes happen in error after not using the app for a 
short time. The way to change this is different depending on 
the Android phone but for most it can be done in Settings -> 
Apps -> Evolve Active, then making sure “Allow background 
activity” is on, battery optimization is disabled and 
notifications and permissions are turned on.
Why does the smart watch not receive message notifica-
tions?

SMS notifications are on.

 

2.) Please confirm that messages can be displayed  

 

normally in the mobile phone notification bar. The  

 

message push on the smart watch is completed by

phone notification bar. (You need to find notification  

        settings in the mobile phone settings, and turn on the 
        notification switch of any apps you would like

music, you can use the controls to play, pause, 
skip, or go back a song.

   

Blood Pressure

Can be found on the icons page as BP, the blood 
pressure should be measured in a rested state 
for optimum accuracy. Take a rest for at least 
5 minutes before measurement. Avoid any intense 
distractions, measure three times repeatedly at an 
interval of 2 minutes. Record the average value of readings 
measured three times.

Blood Oxygen

Blood oxygen saturation (SpO2) is the 
percentage amount of Oxyhemoglobin (O2Hb) 
which has been oxygenated in the blood and
the total amount of hemoglobin (Hb, hemoglobin) 
which can be oxygenated. It means the concentration of 
oxygen in blood.

Note: The blood pressure and blood oxygen data are for 
reference only and should not be used as a basis in medical 
aspects.

Pedometer

The pedometer face shows your steps taken 
for that day. Wear the smart watch on wrist
and the smart watch can automatically count 
steps, distance, and calories.

Heart Rate Measurement

The heart rate sensor can provide real-time 
dynamic heart rate data. Ensure there is no 
dust/debris on the sensor. Position on the wrist 
is important so please ensure the sensor is not 
sitting on the wrist bone to avoid inaccurate results.

Note: Please ensure the watch is worn securely. If worn too 
loose, the sensor may not give an accurate reading.

your sleeping patterns. It separates deep 
sleep and light sleep and summarize the total

view your heart rate graph in the app.

Faces

2. Can I use this in a hot bath?
No, hot water produces a lot of water vapor, which can 
easily get into the smart watch compared to liquids. When 
the temperature drops down, the vapor will condensate into 
liquid droplets which will most likely cause a short circuit 
and render the watch unusable.
3. Why is the Bluetooth connecting icon flashing? Answer: 
Disconnect/unpair and connect/pair the watch and phone 
again to fix this
