That IR LED is also used for proximity detection I believe, which is something you cannot turn off.
Why do you want to turn it off so badly anyway? It will barely use power at all.
because i believe is not healthy for your head to receive continuity IR i am wrong?

If you start to fear your IR blaster, don't go out, stay at home. Because sun radiations are way much armful

Cheap Chinese smartwatch with motion sensor

I am just looking for a basic Bluetooth watch to sync with my android phone. My previous one was annoying in that you have to press a button to see the time.
Any recommendations on which one? A long battery life would be a bonus but not essential. Thanks in advance.

NO1 D5+ tilt sensor does not work

HI everyone,
i got two D5+ and when one is in use and i turn the to me to look on it the watch turn on the display so i can read the time.
the second D5+ doesn't do this.
Possible that this is a software issue or is it a hardware defect ?
Thank you !
Do you mean the screen doesn't turn on when you turn over your wrist? Go to settings, find the auto-wake-up motion, turn it on.

Can I recalibrate the gyroscope? Auto rotate not working well

Hello everyone,
About a month ago I got my LG G6 as a replacement for my V10 (worst device I've owned) through AT&T insurance. I've noticed the gyroscope rotation is barely working. Only about 20% of the time the screen rotates when I turned my phone. I can force it by holding the power sleep button, waiting for the power options to show up then rotate my phone. Most of the time that forces it. Otherwise I have to reset my phone and it works for a while then fails again.
Is there any way to recalibrate the gyroscope?
Have you tested in the smart doctor app (preinstaled) in the window of hardware test? It could show that is not working well.

It says everything is good from my gyroscope to accelerometer and motion sensor.

Screen On/Off with cover on SM-T510 ?

Hello guys,
I have bought the new Galaxy Tab A 2019 (SM-T510) with a tablet protection including a magnetic cover. But it seems that this tablet has no sensor to manage the on/off screen when opening or closing the cover... I have tried some apps like Easy Smart Cover and Smart Screen On/Off but none of them works... do you have any solution ? maybe you know a solution ? maybe an app which uses the front camera as sensor ?
Any news here?
