I am wondering if anyone else is having this issue. I have a Nexus 6P and I am on the $15/mo talk/text plan. This issue only started happening when I upgraded to Android 7.1.1.
Every time I connect to cell, I get an Android system message asking me to “sign in to network.” (See attachment) It is also accompanied by a little ‘x’ on my cell signal meter.
I can still receive calls and texts over cell, but sometimes MMS don’t send or receive. It happens even when I have strong cell signal.
I upgraded my plan to the 1 GB data plan for testing, and the Android system message went away until I reverted to the no data plan, and it came back.
I know it is not a problem that can be solved by reinstalling the RW app, or clearing the cache, because I clean installed Android 7.1.1 from the files provided by Google by flashing via fastboot: 3 times with two different downloads of the files verified with the SHA-256 checksum both times. They were good downloads. I was able to recreate this error after each clean install. It also popped up when I tried it on two different custom ROMS based on Android 7.1.1.
I did file a ticket with RW, but after having 4 different support people take turns replying to the same ticket, all telling me to try fixes like reinstalling the RW app and clearing the cache (after I had told them multiple times I had reinstalled the whole blasted OS, which includes whole new system and cache partitions) I gave up and asked them to close the ticket. (To be fair, one guy tried to duplicate the issue on the lab Nexus 6p, but was unable to recreate it. He was the one guy I felt actually read what I wrote and tried to help.)
Has anyone else seen a problem like this, or am I actually really special like Barney always told me?
