OK, so there are other people experiencing the same **** from SAMSUNG. I'm tired of writing everything again since I did that in anothet thread, but I also experienced troubles with my GW watch(es). Here it is in short again. It started with baro/altimeter not working after some time showing negative heights. Brought it for warranty repair. First time sw reset, did work for about a week or two. Then they cahnged mobo and sensor. Worked for a week. Then I got all new watch (I have two boxes now 
), I was hoping I will get the money back and was looking to buy Garmin forerunner instead. I got brand new watch, which I should sell at the time, but I thought of giving it another try. and it worked for almost two months (if we neglect the altimeter), but today all sensors failed so wake up gesture is not working.
My conclusion was also that barometer is the culprit together with sw, I even accepted that GW doesn't have barometer and thats it... I even like it more when sensor fails after awhile since at least then it doesn't record ridiculous measurements in the activities. But it seem that it messes with other sensors after some time inevitably 😞
I'll try now using it with barometer app uninstalled (didn't know it was possible). with barometer tube there is definetely hw design flaw. it works without activity and that is why majority of people probably don't reaize the problem because they are primarily using it just as simple watch. But, as soon as I go running, after 10-15 minutes probably because of the sweat which somehow provides negative pressure to the tube, watch starts to show lower and lower altitudes going to negative after some time. If I clean it afterwards and dry it, after some time t comes back to normal. BUT, it seems that sw has some kind of treshold after which it starts to ignore the sensor, and after awhile it starts to ignore other sensors too 😞 I also noticed that it starts to work fine for some time after every official update, which I guess comes the same as fw reflash.
both factory default reset and hard reset didn't help. Only thing I didn't try is reflashing the fw through odin mode...
Shame on you Samsung, even the official repair center in Croatia is not informed about this issues and they are following standard procedure (sw reflash, then hw replacement, then watch swap). Even the chief of service has the watch and accepts that he has to reflash the sw every once in awhile...
This hardware is too expensive to show child issues and we all paid too much to be what.. beta testers for Samsung? I'm so ashamed of myself that I chose GW instead of Garmin, because I believed advertisements and that everything in specification will actually work...
yep, still works.. barometer works in gps mode in hiking activity
