I have the S9+ (CE version) and this morning had the bad idea to install the Pie update. One of the most important features for me is the ability to share wifi from the phone at max speed. My land line is very poor, and I got me an unlimited 4G+ plan just for this purpose. So as with the Xiaomi I had before, as well as the S9+ under 8.0, I had the option to set up the hotspot to emit at 5 GHz, and it worked fine. Just this morning I downloaded an update at 19 MB/s.
So I update the S9+ to 9.0/Pie, start the hotspot and see it's only emitting at 2.4 GHz. I go into settings and boom, the option to use 5 GHz isn't there anymore. Did I just performa an update that threw me 10 years back and onto a 100€ phone? My hotspot settings "Advanced Options" only has one option about PMF, I had a "5 GHz" toggle 2 hours ago on 8.0.
I called support and all they could tell me is to backup everything, reset the phone and "see how it goes". Before I waste my time doing that, probably for nothing, I'd like an official answer: did the Pie update on the S9+ officially remove the ability to share the phone on 5 GHz wifi? Or is it just a temporary fluke and that will be patched (though it's been 2 months now)?
Thanks for the feedback, @Neofit26!
It may be that it's simply a teething problem with the OS.
My advise at this point would be to submit your feedback via the Samsung Members app, so it's able to make it's way to the developers.
Thank you for your reply.
Just to make sure, what do you guys see in your Settings in your Hotspot "Advanced Options" menu?
8.0 on the left, 9.0 on the right, I lost the 5 GHz option on the right.
In front of me I have a S9 running Android 9, One UI 1.0
There are a few small differences that I can see, mainly the Build Number
Can you let me know what network you're on and the full model number?
I can then try and find out the latest Build Number for your phone/network.
Wait, what now? The members app is telling me in English that it doesn't speak English, basically. And I do have French as a secondary keyboard, available as a swipe on the Space key, if only you'd let me open said keyboard . Besides, I am pretty sure that there are more English-speakers who can help me than there are French-speakers, if only statistically. That screenshot is wrong on many levels.
No answer from the members app, not totally unexpected. I fixed it by myself. In case it helps someone else, here is how.
I downloaded the exact same firmware that was installed after the patch, 9.0, G965FXXU2CRLI_G965FOXM2CRLI_XEF, from sammobile. I flashed it and it reinitialised something and the 5GHz option is back. I have now the exact same version of the firmware that I had after the update and before flashing, and didn't even need to reinstall any app or reconfigure anything after using the "HOME_*.*" file to flash.
