We started collecting this data on FB group. Please add yours if your watch turned to be faulty, using this scheme:

Name (nick) | version (CN or US) | serial number | supplier | date of purchase | date of failure

If you are concerned about privacy replace the last 2 digits of your S/N with “xx”.
Thank you in advance.

What is the BT/wifi issue? It manifests itself when after some time of working good bluetooth connection range of your watch permanently drops to about 30 cm from a phone. WiFi range also drops accordingly. Basically you're losing all wireless communication - no notifications, failed wifi test.

Latest info:

  1. Chinese watches - all faulty units have their S/N starting with 13426/... or 14357/...
  2. English watches - all faulty units have their S/N starting with 16121648 or 16121649. No failure reports for newer 16121651 yet. There are also some older 1612 ones with mixed numbers from chinese serials, we don't know about their failures.
  3. There is only one "unofficial" company statement made by Huami representative on FB group. The company is aware of the issue, they claim only less than 1% watches are affected and they already made various software and hardware "improvements".
  4. Chinese users are getting replacement watches very quickly. But their watches still fail again with the same issue, there are cases of 2nd or even 3rd replacement procedures. Draw you own conclusion if the supposed hardware "improvements" were actually done by Huami...
  5. The most probable cause of failure is electrostatic discharge coming from human body in certain circumstances, eg. undressing. Any modern electronic device should comply with industrial standards for that matter (IEC 61000-4-2) and should withstand static discharge. As the watch is product of China - probably it was never tested according to the standards.

Hi,
when my wife come back, check the serial of the amazfit. Same problem but only with software update apparently.
I think is software problem and not hardware problem... but is only my thinking!

The problem is very well recognised on chinese Huami forum. If reported, chinese moderators no longer offer any software/firmware related solutions, they provide a phone service number to arrange replacements. There are MANY replacements going on there and, sadly, replaced watches fail again.
Huami refuses to give any information about what is going on.

There are already cases in progress. Basically if the watch failed within 45 days period from receiving it, Gearbest offers full refund. Theoretically, as no one got the money back yet ;) In other cases they offer "repair". They claim they will contact Huami for repair instructions and they repair watches themselves(!). That kind of info one of us got from them.

They are a bit early for April's fools aren't they?

The fact is, they know s**t and that's why they plan to repair them. There will be a technician checking the function and they will get the information that it can not be repaired.
You need proper tools to disassemble the watches and to mount them and check if they are sealed properly.

Latest info:

  1. Chinese watches - all faulty units have their S/N starting with 13426/... There is a new production batch starting with 14357/... and no reports about failures yet.
  2. English watches - all faulty units have their S/N starting with 16121648 or 16121649. No failure reports for newer 16121651 yet. There are also some older 1612 ones with mixed numbers from chinese serials, we don't know about their failures.

I'm searching inside dmesg and firmware...

[email protected]:/ $ cat /system/lib/firmware/wifi/
bcm43438.cal fw_43438_a0 fw_apsta_43438_a1
cal_43438_a0 fw_43438_a1 fw_bcm43438.bin
cal_43438_a1 fw_43438_a1_test fw_bcm43438_apsta.bin

why there is different firmware?

-rw-r--r-- root root 370594 2008-08-01 14:00 fw_43438_a0
-rw-r--r-- root root 359859 2008-08-01 14:00 fw_43438_a1
-rw-r--r-- root root 329723 2008-08-01 14:00 fw_43438_a1_test

Anyone have rooted watch can test to change with other?
With a rapid search i think the chip of wifi/bluetooth is the same of raspberry pi 3.
Thanks

Hi all, now that amazfit watch is available again at gearbest, I've asked them if their stock is still 13426/xxx.
No meaningful answer unfortunately. But they are so kind that now I feel guilty :(

Your original question is "Dear Sirs, according to a user survey there are a lot of bluetooth/wifi issues related to devices from production stock whose serial numbers start with 13426/... (see this thread: https://forum.xda-developers.com/sm...azfit-sport-watch-pace-bt-wifi-issue-t3560649 ) May you please confirm that the devices you're selling are not from this faulty stock? Many thanks in advance, Fabio"

Here is the answer from Our Customer service Team:

"

* Fast delivery for catching the market.

Unfortunately we got the first faulty chinese watch with 14357/... serial number.
There are some speculations as to the cause of the failure and one of them is ESD (electrostatic discharge). Some people report their watches happen to go into "shutdown confirmation" screen by their own. It was my experience too, before my watch failed.

Updated database and info in 2nd/3rd post.
As more and more watches with new S/N 14357... fail it means Huami did not fix the problem.
The most probable cause of failure is ESD (electrostatic discharge).

Has anyone got any support from the Amazfit pace website? I've put a support case in about 2 weeks ago and haven't had a single reply back.
