If you have the Universal Launcher set as the Home page, check the settings in the UL. It has a section to auto check the HR every XX minutes. If you are not using the UL interface then I think it is in the phones settings to also check it periodically.
You canāt do anything about heart rate sensor in the watch settings.
The sensor is supposed to come on at intervals to establish if the watch is being worn or not.
Basically because many faces have access to the sensor and it works in conjunction with steps counter
Can this be turned off using hidden settings, the worse thing could be if a child takes up the watch and the laser suddenly switches on and shines in the eye
No, as I said above it canāt be turned off.
I will make sure but I am fairly sure that it cannot be done.
Has there been any clarification or further info on the volume level problem for the T-Max S?
I have re-set the watch to factory (twice) including the V1.9 firmware update and the speaker and mic volume are still extremely low.
I canāt take phone calls on the speaker when I am outdoors - even in isolated areas it is too difficult to hear and to be heard via the mic. (Itās half the volume of my Prime_Se) and itās not much better indoors.
Although i have done this before i will re-test today ( speaker only ) as now works 100% in car. I have tested V1.9 and Note firmware with better results . The speaker only option could do with being a little louder but not to the level you are experiencing
Okay . Just tested again . With carkit nice and loud ( no problems ) . Speaker phone inside okay but not loud enough . Outside very poor .
@pablo11
This is the same with Ticris v1.9 and Kospet firmware .
Needs a tweak mate 
@Dr_Andy,
thanks for taking time out to test it again. I will be forever grateful if the mic and speaker volume can be resolved to be louder. I really like this watch and hope this volume thing is not the end reason to stop using it.
Can you confirm that audio is ok using headphones please @Dr_Andy_Vishnu
Running tomorrow so will confirm . Car kit - perfect . Music audio with earbuds - perfect
@pablo11 headphone test: For me, the received audio in the headphones is ok, but audio for the other party (through my mic) is incredibly low, to the extent of not able to understandā¦
@Dotsfar ⦠same with mine,
plus sound output with phone calls is also poor.
@Dotsfar is right. Headphone is fine.
Have you tried with a car kit ? Mine with car is perfect . Thanks
But he says person recieving call cannot hear him when using headphones. Is this the same with yours ?
Itās easy to try, when calling the answering service and playback afterwards.
I dont have a issue with this
I have no sim in it atm. I will try later.
Which firmware ? I use December Ticwris FW.
V1.9 and also tried the kospet
