Hi everyone!
This is my first post in XDA. I own an Amazfit Stratos 3 since friday. My barometer app always shows a wrong hPa value for the pressure. I don't know exactly why. I also own a Suunto with baro capabilities, and it shows a correct value.
The correct value should be between 990-1020. Suunto shows 1015 hPa (left watch) but Amazfit Stratos 3 shows 904 (right watch). It's a very low value. I attach a photo showing the comparative.
I don't know why, but in general, it detects if I'm going up the stairs. It seems with just a pressure offset could solve my issue.
Anyone have experienced this issue? Is this a bug? Is there a way to calibrate my pressure sensor? Is my watch defective?
Thank you very much.
Regards.

Hi there people. I need your help.
As you may know the moto 360 sport features a barometer among other sensors.
As I have been playing around and developing an app for that I found out that actually it does not work correctly.
To be more precise it gets one reading and then stops until reboot, or random. This should not work like so.
I have contacted several developers and all agreed that the sensor does not work correctly.
That leads me to think that either it's a huge software bug or Motorola has screwed us for 2nd time (1st is battery capacity)
What I am asking from you is to download AID64 (shows sensor info) and check if it works for you.
It will be working if you change location (eg walk, change location, or move your hand). If it does not change then no.
Thanks in advance.
P.S. Similar thread in G+ moto 360 community
i believe you refer to pressure sensor, it stays at 738.0 hPa, no change after movement

Yes man. I have already opened a case with Motorola.
You can compare it to how it changes if your phone has one.
It's a big ffff bug. I hope is SW.
hallo everybody
i've bought a BV6000 (firm ver 20160713 chip MT6755 (Helio P10)) but the proximity sensor is very weak, i've asked on official forum for calibrating\change threshold, but no one have published my question.
now my idea:
on engineering mode i've found ps calibrating tool but nothing happens after calibration and reboot; the default threshold is set to 40 (less than 1cm) and if i could set to 5 or less the range arrive to about 3 cm.
is some days that i try all solutions founded on the web but no one works...
now someone have some skills in calibrating the sensonsor manually? i've also tried with DHD Proximity Recalibrator but give me a kernel error.
maybe edit some files in /sys/devices/als/subsystem/drivers/als_ps is the solution?
any other idea?
thank you!!!
xposed and the module: http://repo.xposed.info/module/com.mrchandler.disableprox
I have an MTK and it kept hanging up when I brought the phone close to my face, so I had to disable it completely.
yeah i've tried this module but is a bit too invasive and need a tasker profile to turn off screen on call, i would remap the threshold (if is possible!)
/sys/devices/als/subsystem/drivers/als_ps there are many files:
a "config" file with
(3 200 0 0 50)
a "status" file with
CUST: 1, (-1 0)
REGS: DF C1 00 06 00
MISC: 0 0
what makes me angry is the farest PS sensibility from engineering mode! (hardware testing>sensor>light/proximity> PS calibration) if only is possible to manually reduce threshold!!
engineering mode ps calibration...
UP! i attach two photos of the engineering mode that show the lower threshold.. but after calibration nothing happens...
I put 4 times complete analysis of proximity sensor issue on Blackview forum. Every time, they delete my post.
None of the calibration would help.
The only solution is to replace one rubber part from phone. More details here:
thank you
at now i have do a tasker scene that block upper buttons and an "immersive mode" shell during call (show up when call+phone app is on screen and hide if not).
is a patchy solution but it works
maybe if i have some other hardware problem i'll try to open the phone
bye!
Could you upload a video of your solution? How did you reach the rubber part?
Thank you!
I could not upload video, because I did not recorded the process, but I will try to describe this process.
Video comparing working BV6000 and broken BV6000 proximity sensors:
https://www.youtube.com/watch?v=s8NYcs-Yo5E
Go to service mode *#9646633* and select
Hardware-->Sensor-->Light/Priximity Sensor-->PS Calibration
If your BV6000 acts like the right yellow model, then you are affected with this issue.
Root cause:
Proximity sensor is good. Rubber part covering sensor is really poor quality and it has a gap just above sensor causing light leaks.
PS reading 0-80 are considered as "far". Phone cannot get proximity readings >100 which are considered as "near", so the phone does not dim the screen at all. This is causing a lot of unwanted touch screens while making a call. If the proximity readings were possible in full range 0-255, then the threshold settings 40-100 would be perfect. This issue cannot be fixed by any calibration.
On my working, green BV6000, this rubber part has a bit different shape and it is made with much softer rubber. The edge which is covering sensor is also much tighter than on the yellow one.
Workaround:
Disassemble the phone, like on video here:
https://www.youtube.com/watch?v=9yLEemeXFnY
You do not need to disassemble the whole phone. Just get to the part, when you can detach main board.
Then turn upside down this rubber part covering proximity sensor. It is not meant to be mounted this way, but it will fit. Basically the part which was close to the screen should go close to sensor. This will make gap between rubber and PS sensor smaller and there will be just tiny light leak. It will not make full proximity range 0-255, but it will improve a lot.
On my phone proximity range expanded from 0-80 to 0-200 after this mod. Phone will dim the screen while making a call, if you head is 1cm above sensor. On working phone 0-255 it dims screen in 2-3cm range.
The only 100% solution:
New working rubber part to be sent to all affected users.
Shame on Blackview, that they not only deleting my posts about this issue on their forum, but also reporting my posts, when I put this analysis somewhere on well known Android forums. This is like they want to cover a problem and not resolve it like they did with faulty OTG boards.
thanks for the brilliant hardware workaround, but if i want to change the values showed in this app
i've seen many phones with different resolution\max range (higher than 1cm!)
how i can edit this values without MTK engineer tool (tried but dont do nothing for this issue)?
thanks to all
PS. BV6000 is a good phone for the price, but this issue is really annoing!
PPS. BV6000 have adups fota search online and be paranoized!
I have tried it by placing the rubber above the sensor both ways but it still doesn't work. Whenever I make a call the screen remains responsive and many apps open up or settings mess up every time. There is no end to it.
Please help. I'm really annoyed with this issue.

Have a bit of a problem with my Gear Fit 2. I usually have HR set to Auto, so it monitors my HR always, and when i remove it it turns it off, or that i did sometime ago, now when i remove it from my wrist it won't turn the HR sensor off, it'll keep measuring something(150-220HB/s), which can be annoying. Also i have it set to lock when removed from wrist, but it stopped doing too.
If any of you have had this issue and somehow solved it i would be really grateful!
(Just to mention i did try Factory reset and my phone is S7 Edge currently)
HI All,
Had my bip for 2 weeks, all working fine until now. Major issue in that the brightness doesn’t adjust when I amend the settings and the backlight (i.e. lift wrist) function doesn’t work, the screen doesn’t light up at all, ever, even when I press the button or flick through the screen menus. Over the 2 weeks I’ve worn it constantly, washed dishes a few times otherwise just your usual day-to-day activities. Everything works apart from this which is a major issue as means the watch is only useful during the day, in dark can’t make anything out.
Can anyone help please?

Is there anything I can try to test the backlight? Whether it is the light itself or some function I may have disabled?
Can I somehow reinstall an OS on the watch itself?
I don't have any warranty or options to return as bought from someone who no longer wanted it (open box but otherwise new).
Hi,
I've got the same issue. After contacting Amazfit support, they say that my product may have a default. So I have to contact Gearbest to have another unit
Do you have any new information ?
Unfortunately not, I did contact amazfit support who told me to video the issue and send it in. I haven't had a chance and as I have no option to return, the watch is just basically gathering dust. When it worked, it worked really well but for the £ I might just purchase a mi band instead.
this seems to be caused by non official faces. put an official face back on and it works.
That didnt work for me either, tried rebooting/restoring to default, different apps on the mobile, as someone not too techy feel like exhausted all options and left disappointed the screen does not increase/decrease brightness never mind illuminate the backlight. Thanks though!
Looks like a recent issue
I got my watch already for a while. Never had any issues until now. Backlight is done after swimming. All the rest still works. Factory reset didn’t work. Adjusting brightness to its maximum neither. So anyone experience with the after sale service?
I’ve bought my watch with gearbest and am trying to send them a technical ticket
my amazfit bip backlight is not working now as well help please!
Dear Members
my xiaomi amazfit is getting the distance mark with incorrect value
sometimes I'm running marking 7km and from nowhere it jumps for 9km.
how to solve the distance traveled?
Thanks
