SpO2 for Amazfit Pace? - Amazfit

Is there any app to measure SpO2 for Amazfit Pace?
I think the required sensor is the same used for heart monitoring ....

Although similar they don't exactly use the same hardware. Blood oxygen level (SpO2) measurement requires at least 2 LEDs with different wavelengths to differentiate between oxygenated and unoxygenated hemoglobin, pulse rate measurements can be done with only one LED. So I don't think it is possible.

So is it still impossible?

App Request: Proper running app with more detail

I am coming from a Garmin Forerunner 405. I seriously am missing it a lot. The only problems I have is that the Nike+ and the built in running app are the only two that actually work outside of using the phone's GPS. My old watch used to tell me pace, distance, elapsed time, heartrate(with a monitor) and if you pressed a switch screen button it would give you a paceman that you could set. It's basically a digital person who always keeps the same pace and tells you how far ahead or behind you are. I also want the display to be always on(during the run) like the clock can. It gets frustrating having to run and play with the watch to see your pace or time. Here are a few screenshots of what I mean. I would be 100% willing to pay good money for an app like this.

trying to undertand the calibration algorithm

i am desperately seeking for a solution with the accelerometer sensor
i cannot use the phone without rotating if i have it on the table or even sometimes in my hand
sensor is off on the x axis = 5 ,
with the calibration tool i have managed to correct it to 3 but if i want to calibrate it to 0 and put it on a flat surface the calibration always fails (i think because the offset is too much it can probably correct it 2 points)
here you can see on the video near the end what i am talking about
i found the file responsible for the calibration posibbly acceleration and gyro sensor
just cannot understand the values inside there are so many numbers so i can try to manually calibrate it
location
sys/devices/14e300000.i2c/i2c-66/66-003a/input/input0/calibrator_cmd
OS is Flyme 4 (Android 4.4)

Yes and no. As for now, it is possible through an APK watchface however the battery consumption will be too big.

Test my new Amazfit GPS Scanner Locator and never lose your parking place...

Hey guys ! Here is my new Amazfit GPS Scanner Locator. The idea is just to store immediatly the current gps location (or may be many locations?) and to display the return direction and distance. The display is like a compass style , the magnetic sensor allows to rotate the compass to real north direction, and it's possible to display the real return direction !
Radar style locator

Congratulations, a very interesting project.
Is it possible to think of having it also for AMAZFIT verge?
Thank you very much
Keep up this good job.

Question Adaptive brightness = screen too dark

Hi,
I have a s23 ultra since a few months.
Everything were fine, but since 1 week, screen is a bit too dark with adaptive brightness on.
I don't why but when I'm at home, the phone is usable but too dark.
Outside, I have to manually increase luminosity.
Do you have any idea?
Do you use a screen protector? If yes is it one of those privacy ones? Those are darker
Have you run Diagnostics in Maintenance menu?
There's a proximity recognition there. Try that.
There are android apps, example, DevCheck, that lets you check sensor data like this one called Light.
Check if everything is normal there.

Hi,
I use the same tpu screen protection since the first day, it's not a privacy one .
I've launched "sensors" and "proximity" diagnostic with no problem
