Question Reboots while switching between LTE and BT - Samsung Galaxy Watch 4

My Watch 4 Classic LTE reboots when I'm somewhere where there is barely any bluetooth range and the watch has to keep switching between LTE and Bluetooth connectivity. It's strange, but this happens every single time when I keep the phone in my room and go to my mom's. Just reboots. Does anyone have the same issue?

[Q] Phone calls breaking up on WCDMA

We have 2 mytouch 4g's. Both of them have problems when making or receiving calls. The calls keep breaking up and therefore we cannot understand what is being said. It seems that the problem is happening when the phone is set to WCDMA or auto GMS/WCDMA. I've also noticed that when I set the phone to GMS only, I get more bars then on either of the other 2 settings and the call problem improves. This problem happens at both my house and also my wife says at the place she works, which is 3 miles from the house.
Anyone else having this problem and any fixes known

[Q] Radio Problems anyone else?

I live in Manhattan, so my day consists of going underground for subway, and then back out at least 4 times per day. I have noticed several times that my radio never RE-grabs a signal when coming above ground it just sits with the bars and an X signifying no signal, in broad daylight...until i reboot the phone and it then promptly grabs signal. I have a buddy with a NS and he noticed this too...we also noticed it happens mostly when we are listening to something when emerging back above ground. Not sure if that has anything to do with it, or if it isjust cooincidence...however, has anyone else noticed their NS radio not grabbing a signal when back in range??? It is SO annoying to be walking around for 10-15min after coming above ground, to notice you have been cut off the whole time.
just instal the airplane mode on/off toggle
and hit it when you are back out on the surface
some times it's slow for the machine to grab signal
yes, i have noticed
like when i go into the basement, or server room, or other places with NO signal
and go back out to a place that I Know there is signal, yet it still in X mode
so, i just swap on/off airplane mode, and it works right away

I'm also a metro north commuter and the same thing happens to me randomly as well. I can go days without it occurring once, however sometimes it'll happen twice in the same day. Attempting to cycle Airplane Mode just locks up the device as well, so rebooting is the only option to restore network connectivity.
Noticed this as well when I'm in and out of subway stations. It hasn't been happening recently but sometimes playing around with the settings in the *#*#4636*#*# menu might help, like selecting GSM PRL or WCDMA preferred.
Anyway, I had the same problem with my Vibrant... never had the problem with my Nexus One or MyTouch 4G. Maybe HTC's hook onto networks better?

I normally loose signal completely when I am in the underground parking lot of my condo building. But as soon as I am outside it connects almost immediately.

I've got the exact same problem, not sure how to resolve it. Really wish they would push out an update and fix these annoying issues.
I've set my phone to WCDMA Only ( since and on boot up it doesnt connect to a network ) & WCDMA Perferred doesn't seem to want to stick.

i have the same problem
Same problem with my Nexus S. Toggling airplane mode don't help. I have to power off/on my Nexus S then I get the signal again.

[Q] Constant switching from LTE to 3G

Hello,
so I got my nexus 5 a couple days a go, and it's my first LTE phone. In my apartment I do not have the best cell reception on LTE or 3G but thats not my problem. My phone is switching from LTE and 3G quite often. I wouldn't care about that except that once it decides to switch it seems to drop the one connection and then take 30 seconds + to get the other one, so I have missed several calls because of it.
it's not the biggest deal, because I will just disable LTE when I am connected to my home wifi, but I am wondering if this could be a hardware hardware problem that I should call google about or a software problem that I could fix/wait for fix.
Thanks in advance!

I have noticed my nexus 5 drops to 3g when sending or receiving SMS. I am probably wrong, but the phone could also be switching off LTE to save on battery but connecting back to LTE for background data sync.
Same here on the signal change upon receiving SMS and email (exchange). I am now dropping calls more often on this device vs note 3 when either SMS or email arrives.

Bluetooth range (and WIFI stability)

Hi, I make my comparisons versus my Gear 2 and just what seems reasonable.
With my Gear 2 I could be in another room in the house, a good 15 meters away and no issues, with the S2 (especially with the new function of vibrate on disconnect) it constantly drops when I move room even sometimes for no reason.
Also setup the WIFI option as a backup but again half the time it shows the WIFI signal as poor and I am sat right near the router, which is working 100% fine with everything else (i.e. mobile, laptops, tablets, tv.)
i get the same, bluetooth just disconnects , don't know why. also bluetooth music earphones cut out and range poor
I have exactly the same range problem on galaxy s6 edge plus with all bluetooth devices.
It's shocking , if Samsung don't fix these issues soon , will switch to fist android wear device with lte , there lucky the urbane 2nd got discontinued
A hard reset helped but still disappointing

Anyone else experience cooldown mode on 3G?

For the second time now, while talking on the phone and connected to BT wireless in my car, my S2 3G has automatically gone into cooldown mode after getting noticeably warmer on my wrist. Just wondering if anyone else has observed this?
I have had this happen on 3G with a weak signal. I think I have carried over a 30 min conversation over bluetooth.
Thanks for the data point. I may have been in a week signal area. Most of the time, I have no problem over BT.
