I have a Samsung S10 (O2 pay monthly contract) and a Samsung software update automatically downloaded yesterday which has caused glitches I have never experienced before. My call forwarding is enabled and can no longer be disabled. The call forwarding to voicemail phone number that was set up has been removed and a "failed to read data" error message pops up whenever I tap anywhere in the call forwarding/barring sections.
If I try to enter a number in any of the call forward options eg 'Always forward' and click "enable" the number doesn't get saved and disappears. I can't disable the call forwarding meaning that I can't receive calls. I can make calls however.
I have spent hours with O2 and Samsung which was a massive waste of time as neither companies understands their own products.
I have done a network reset. Tried disabling call forwarding in safe mode - same error message. Did all the troubleshooting I could find. Tested my sim card on the Samsung app - works fine, I can make calls and access all my contacts. Tried the ##002# to cancel all diverts but it didn't work and got an MMI error code 801. I don't want to turn off my voicemail so didn't try 1760.
Another issue I have is the voicemail number I was given by O2 to forward calls to (not 901 but a 11-digit long number) in the "always forward" setting was removed after the latest update and I didn't make a note of it. When I asked O2 they had no idea what I was referring to. Does anyone know the number? It's not 901 but a +44... number for the voicemail.
Any help would be much appreciated. Thank you!
Have you tried a factory reset?
Your choice of course but it's not working perfectly no so I don't see much choice.......
