I have a nice camera and a neat organizer unless I'm on wifi the weird thing is i can go 5 miles down the road works perfectly i returned mine sticking with my s8 which works fine it all started when I got an update
There must be some major issue going on. I got an s10 regular like 2 weeks ago and everything worked fine until like 2 or 3 days ago. Service barely works and calls and data would barely work. I went to a samsung store and they couldnt figure out the issue so they replaced it for me but my new phone wants to get the carrier update also and Im worried my new one will stop working if I update. Tmobile or samsung needs to FIX ASAP!
1st.. Just for clarification, when using wifi calling it does NOT use the cellular network one iota. Your phone is using the high speed internet wifi router as your tower. Now with that being said. Many wireless routers broadcast at multiple spectrums 2.4ghz and 5ghz.
As a Network engineer for a competitor of your cell company I would ask you if the wifi on your phone works else where aka work, Friends house etc.. If it's still an issue then yes thier may be a software issue on the device/s.
Now if it works fine elsewhere then the issue very well may be with the wireless router. Simplest way is to connect to the 2.4ghz if you connect to the 5ghz automatically and test or vice versa.
If that fails, then you will need to find out 2 things from your ISP. 1) What are your download / upload speeds. If it less then 10mb download and 5mb upload if may not work. 2) Is thier any update that needs to be applied to the router. The new Galaxy s10 line has new features to handle more advanced routers.
Finally, if all else fails. Inquire with sprint about a 4g Network Extender. The physical extenders do a much better job than wifi calling software on all phones.
Hope this helps
