Have been using new Galaxy S10+ since 3/6 and data speeds are horrid, almost non existing even though phone shows full LTE signal. Have done several PRL updates and profile updates. Same results in couple different cities.
The only update I've received was the Feb 1 security update which was installed on the 6th as soon as the phone was activated. However, so far today evening seems fine. Had GREAT downspeeds this am (119) and up was 4 mpbs. Out of town now and it still seems great.
There was an update that went out yesterday, so hopefully it already downloaded to your phone and that's why it's working better now. Let me know if there are any further issues.
Okay so I did that, and went ahead and updated my PRL and Profile and no luck fetching an update afterwards. Mobile data speeds are still slow or unresponsive.
I assume this is a known issue with other S10 users? I've seen a few threads about it here and on Reddit. If so, it makes me feel a little better since I know I'm not the only one 😬. Thank you Cat for taking the time to look into this matter!
