    Hello everyone,

    I have a OnePlus 9 Pro with Ram 12gb and 256 gb.

    I am on Cosmote Greece Network and I live in the center of Athens.

    My phone has Oxygen with Android 12 the last days and 5G does not works.

    5G didn't work on Android 11 also.

    The phone bought directly from OnePlus Europe's website.

    The process with *#*#4636#*#* doesn't works. When I put *#*#4636#*#* on Google dialer and on other dialer apps like Truecaller doesn't work.

    I tried meny apps like 5G Switch - Force 5G Only but they doesn't work.

    My provider Cosmote has activated 5G on my SIM. My SIM has 5G in other phones but not my phone.

    What do you propose to me????

    Please help...

    In Android 11 yes I was able to get 5g

    I also checked with us there are full of people with this glitch, in my opinion in order to wake up oneplus, need to send a lot of reports and bugs to them. This is what I'm starting to do. Do you also have people complaining about it? Friday I'm going to do a device reset, maybe this will help. Which I'm not sure but I will try anyway.

    I did a factory reset but didn't help. That same situation without 5g still exists.

    I want to try something, in front of the company, I want to draft a letter, worded with all the glitches and problems that there are, including videos or photos. And email them. Let them see the extent and amount of bugs. And I would also love if there are more users from different countries who come across it can help. Are you interested?

    Hey there

    I have tagged Greek moderator @gaster who may be able to assist.

    From looking at the Cosmote website, the 9Pro is listed as a verified device.

    Not sure yet. If it works we ll find out by thread's author results if he tries. So keep an eye here just in case I would suggest.

    Hello people! I have the same problem with my OnePlus 9 Pro here in Greece(Athens). After the update to Android 12 and Oxygen OS 12 I've lost 5G signal. My provider is Cosmote. So, I will also start to sent bug reports to OnePlus to solve this problem.

    Hello all,

    The same problem in my device as well - I'm facing the same issue just after the upgrade to Android 12 - Ticket has been raised to Oneplus but still ( more than 15 days ) waiting the feedback from developer's team.

    I'll keep updating this forum in case of any solution
