Galaxy Watch 5 Pro sometimes very laggy when going to the LTE mode

[Spook3r]

Hi, 

I have my Galaxy Watch 5 Pro LTE paired with my  Galaxy S23 and from time to time, the following issue happens. 

It is my typical use case that I go jogging with just the watch where I rely on its LTE connectivity - I use a separate number for the watch, I don't clone the phone's SIM to it.

Typically, all goes fine. I put my Galaxy Buds Live on,  leave the apartment, the watch is still connected to the phone. I start YouTube Music. I have it 6 floors down on the stairs where somewhere in the middle the connection to the phone breaks and also the music stops, which is expected since the watch need to establish the LTE connection to resume the data stream.

When I get outside, I start the jogging logging activity in Samsung Health and after running for a few hundrets of meters, the music playback automatically resumes. Prefect.

But sometimes, the watch suddenly become very laggy just about at the moment when I get outside and I want to start the jogging logging activity. Literally, it does not respond for tens of seconds. It somewhat recovers eventually (still feeling a bit slow though) but I found that it loses its sound playback capabilities (does not play any sounds through BT headphones or its speaker including the system ones) until I restart it. Sometimes, also the logging activity crashes during the run.

Any ideas what could be wrong?

I have the latest software from the December 2023 update and I also tried to factory reset the watch. Nothing helped. It might be worth mentioning that the watch might sometimes be able to briefly reconnect to the phone when I get outside due to less obstacles in the way. Maybe it could confuse the BT/LTE connectivity service, causing it to move the system into an errorneous state?

Thanks.

Thank you for reaching out. I can certainly understand your concern with your Galaxy watch 5 pro appearing sluggish and I would be happy to look into this further for you. If the watch screen is slow to respond, frozen, or not responding at all the issue could be caused by outdated software, a third party app, or even the watch's physical condition. Unclean hands, optional accessories, gloves, and sharp objects can also prevent the screen from responding properly.

Another step I would recommend is disconnecting from your phone before leaving for the job as it may be trying to repeatedly connect to your phone instead of the LTE if you are still within the distance. 

If you have tried the troubleshooting steps provided and are still experiencing these symptoms, I would recommend a service repair. For in-warranty repairs: Please feel free to reach out to us directly via one of the following options and include a link to this thread.
