The call will be blocked all the time until the other phone hangs up. Did you know about it?
Yes, this is normal, unless you have the call over VoLTE, (Voice over LTE) - then you lose internet connection while calling. It's how the cellular network works.
As for your successful reports - yes - this is how it usually works, most of the time. There is a slight chance for unsuccessful re-establishing of 4G and wifi - as I documented. The actual reason for my testing is that two years ago, I were flying on 4G , and lost connection - then the disco came, and did a circular landing, with no chance of re-connection (I tried wifi, and even re-started the controller after the landing. - until I rebooted Disco , the glympse, wifi, 4g could not be re-established.)

Hello. Flying a Disco with a large capacity battery mod. Using the Huawei E3372 modem with a 128Gb microSD for video over Verizon in the US. Here's the problem I'm facing. On two separate long range flights so far, I've had the 4g mods "lock up". Here's what happens: Somewhere along the flight I hit a spot where the 4g signal is lost (due to distance from an antenna, aircraft orientation, whatever). Normally, when that happens, when the craft gets back in a good reception area (say in a minute or two), telemetry and FPV comes back and my glympse feed starts updating again. But twice now, I've had where it never reconnects. The first time, the Disco was over an hour away. For an hour I waited watching the skies until it came home. Something in the Disco had locked up to the point that, even when it got back to me and began loitering, I could not reconnect on the direct wifi in order to land the drone. I tried controller off and on, etc. Nothing worked. After the 5 minute loiter, the Disco auto-landed with me never regaining control. I powered the Disco off and back on and, as soon as I did so, everything worked including 4g connection and Glympse. Yesterday, I had a similar experience when I was over an hour and a half into the flight. I had had two momentary signal losses where they had regained. On the third one, I never regained telemetry, FPV or glympse. The drone came all the way home (through the exact same areas it had passed through outbound that have great coverage) with the connection never regaining, with the exception that I got one solitary glympse update about half way back. This time, I was able to take control via direct wifi when it got back. Again, after I powered the drone off and back on, everything worked fine. I have eliminated heat as the likely cause (good ventilation, cool weather, etc). I am running continual video recording onto the microSD in the Huawaii modem. On the first flight (the one where even wifi connection didn't work), the video file that was being written at the time of the loss of 4g control was not closed properly--clear that all connection to the modem had stopped. I don't think it was a cabling issue, since a power off and on immediately restored connection. On the second flight (where 4g and glympse quit but I could control via wifi), the video continued to record to the SD card. Any thoughts on what is occurring?
