Samsung Galaxy S8 - No 4G LTE and spotty 3G after Oreo update

After updating to Android Oreo on August 8th, my Samsung Galaxy S8 has not received 4G LTE service anywhere.  Additionally, I rarely receive 3G service.  I mostly get full bars but no 4G/3G service.  The phone is less than one year old, has suffered no water or drop damage, and otherwise works perfectly.

 

I have updated PRL and profile.  That did not work.  I have changed the network mode to every option available.  That did not work.  I have taken the phone to a Sprint store, where they did the usual reset.  That did not work.  I have removed and reinserted the SIM card.  That did not work.  On the advice of a Sprint tech, I took it to a Samsung authorized repair facility, where they replaced the antenna.  That did not work.

 

Any suggestions?  At this point I'm considering returning the phone and moving on to Google Project Fi.

anyone else around you that has a Sprint phone? and if so are they seeing the same thing or just your phone?

 

and in between those locations does it ever improve or does the signal stay the same no matter where you go?

These are pretty big areas. Are there specific zip codes that you are in?

Re: Samsung Galaxy S8 - No 4G LTE and spotty 3G after Oreo update

This is the exact problem I've been having for the past 2 weeks. Prior to this update I had LTE service most places I went around NYC. Since the update I haven't been able to get anything higher than 3G, and even that only 50% of the time. My Galaxy S8 is only a few months old and has no damage, this is frustrating.

10128, 10467, 11419. My bf also has sprint but an iPhone and he does not have any of these issues. So I'm not sure if its just specific to Samsung +Sprint, or I just got unlucky when I did the update.

Since he is not experiencing the same issues you are, let's turn to the device. Have you done any troubleshooting, like a data profile update or reset the network settings?

I have Updated the PRL and Updated Profile multiple times. Tried switching to different networks and back to automatic. It shows full bars most of the time, just does not have any network connection or only goes as high as 3G. Anyway to just uninstall this update, or revert back to before I did the update?

Try a ##SCRTN# first while in good Sprint coverage and give it a try.  If no good, then do a ##UICC#.  This will force the device to reprogram LTE.
