FP3 Android 10 WiFi 5Ghz unavailable

Apart from Google Drive, what is the recommended way to backup FP3? Still MyPhoneExplorer?

Hello everyone! I updated to FP OS A.0033 yesterday, so Android 10 here i go. Before that I also changed/set the wifi band to 2,4 Ghz while using the last Android 9 update. Now I cannot see the submenu/option to select the wifi bandwidth on Android 10. Does anyone know any workaround without having to factory reset the Fairphone?

Thank you

My submenu is back again. I don’t get it… Maybe it depends on whether wifi is active or not. I’ll keep an eye on that topic.

Does anyone know an app or something with an option to switch the wifi band from 2,4 Ghz to 5 Ghz and viceversa?

I can’t promise a reset to work longterm:/ I am back here after one week that the chooser stayed available after the reset.
Just to pitch a few ideas:
I installed and deleted the german corona warning app.
The recovery I went through was the one found within the settings menu by recovery section. In case I am motivated, I’ll go for the fastboot way using the Android image. if someone else wants to give that at try too;) hopefully same version install keeps the data+apps.
Iam having f-droid installed, next time I’ll drop that for the time being.

Actually this time Iam not even sure I used the chooser. It just disappeared and Iam locked to 2.4Ghz Wifi and 5Ghz only access points are not even displayed (same symptons).


My band chooser also disappeared at some point, but it seems to still see and use both bands, so it’s ok for now. Some other settings have also disappeared, but funny enough they still show up in the settings search.

As the others have said, I hope a solution can be found that doesn’t involve a full factory reset. (just a hassle and time)

Thank you for mentioning this bug. I thought I am dumb because I can not find this option anymore!

I will not do a factory reset because of that, as it (hopefully) will be fixed with a software update. Sadly there are a lot of bugs in Android 10 on my Fairphone 3+ (including the wifi reconnect bug, around two times per hour) so I guess we have to wait for an update to fix all these issues.

A few weeks ago I did the Factory reset. Well guess what. It worked…For about a week or so… Now it’s gone again and my FP3 is developing even more bugs over time (or I’m just noticing it over time)

Maybe I really do have to revert to Android 9 if all this continues. If Fairphone still doesn’t give a cr*p about fixing bugs, my next phone definitely won’t be the Fairphone 4. I’m probably going to switch to Shift. Just because I know they’re more reliable.

You are right, there are more and more bugs, which are very annoying.
The “funny” thing: Not only the wifi band chooser disappeared, but also the “Keep on wifi during sleep”-chooser: Fairphone 3 loses wifi connection

After few month owning the new FP3+, I really don’t know what to do anymore. Dozens of bugs, no help from the support and not one single update to fix all these bugs. And even the Google security patches seems to be on hold. Latest patch was from October. November patches are missing, now it is already December.

I can’t comment on the bugs but IIRC the schedule for security updates has always been quarterly not monthly for the FP3. I don’t like this too much myself, but from my perspective this is not part of “an Android 10 desaster”.


Easy, boy. Even the Pixel lineup from Google has no December updates ready, yet…


Yes, sure. But we don’t even have the November updates. That’s what I meant :wink:

Oh, I did not know about that. Thank you for pointing this out! I just was used to get monthly updates from the other smartphone brands I had before.
You are right, the security updates are not part of this desaster. But the limitations while calling are - in my personal view. But this is even more off-topic, I am already in contact with the support since months to get back a normal calling-functionality :wink:

Sorry for off-topic!
So, if there are solutions or hints to get at least the missing menu items (wifi band chooser and wifi sleep chooser) back: Would be happy to know about!

This brings me to this question: Is there an option in adb to select the Wifi band? I did some research but was not able to find anything.
If somebody knows about this, I would be happy if you could share your experience!

Hey, I’ve just updated to the latest FP3 Android stock firmware and afterwards the Wi-Fi Band Option was gone from the Advanced Wi-Fi preferences + I’ve had 2.4GHz selected before the update so this option was still acitve completely disabling 5GHz for me.

After multiple reboots and back and forth I figured a way to restore the Wi-Fi Band menu option.

  1. Push power button until the power/restart/screenshot menu appears
  2. Push (and keep pushing) the “Power-Off” Option until a dialog for “Safe Reboot” appears
  3. reboot into safe mode
  4. go into wi-fi preferences, advanced => WiFi Band should show up again
  5. Select 2.5ghz, then “Automatic”, then reboot
  6. verify that Wi-Fi Band option is now available again

Warning about Safe-Mode: This will reset your home screen widgets, potentially do a screenshot so you can configure your widgets again afterwards.


When you are in Safe-Mode, @Simon1 workaround also included:

  • Set back/reset the network settings (system=>advanced=>reset options=>reset WiFi, Bluetooth and mobile settings)
  • (dont know if necessarry) restore default settings in the developer options (last setting in the dev opt list) and disable the developer options afterwards.

Yeah, that works! Great workaround - thank you :slight_smile:

There’s a big BUT! After normal restarting I noticed that my audio player app widget was no longer on my homescreen. Soon afterwards I received a call from a number I recognized but the contact name didn’t show. After the call I checked my contacts app and nearly all my contact details were missing. Fortunately I manually synch them with my email account as soon as there’s an update to one of my contact’s details, so I was able to restore the lost information. Be aware of this!


1st I thought it doesnt work for me!

But after the following two steps it worked:

  • Set back/reset the network settings (system=>advanced=>reset options=>reset WiFi, Bluetooth and mobile settings)
  • (dont know if necessarry) restore default settings in the developer options (last setting in the dev opt list) and disable the developer options afterwards.

The network reset should be added to your howto! THX a lot for your research!

Disappearing of some widgets after saveboot is normal.
I sync my contacts with the DAVx5 app to my own private nextcloud server and nothing was lost or had to be restored after the saveboot. I recommend this setup to everyone!

@Simon1 Did you do these steps in Safe-Mode as well?

@hypnotoad Here is the official Google documentation on Safe-Mode. Yes the Widgets are getting reset, the contacts problem shouldn’t appear and might have to do with some caching mechanism.

I was quite upset with the Wi-Fi issue appearing last night, glad I spent the time to register here and leave a comment. Have a nice New Year’s Eve everybody.

Thanks for the additional information! I wasn’t too concerned regarding the widget, but the contacts issue could have been rather frustrating :thinking:

Yes, the steps were made in savemode. And afterwards I had to restart in savemode again to get the select WiFi option.

Wish you a great new years eve, too!

Thanks! Reset Wifi in Safe-Mode worked for me.
