Cell and wi-fi connectivity is still no more reliable than when I got my first mobile phone 3 decades ago? Everything else has improved. The screens, the designs, the storage, the battery life, the features, yet for some reason we still get the same lousy reception from the 1990s .Why is it accepted by Apple and phone companies that I can have "no service," yet simply turning Airplane mode on/off forcing the phone to search again magically gives me full strength 4G again despite standing in exactly the same space? Another example - every day I use the tube (subway.) Each station has wi-fi. The train stops at each station for a good 30 seconds, yet that apparently is not enough time for the phone to connect to the wi-fi signal. This is simply not good enough. I put up with it twenty years ago, why do we still have to put up with it now? Why can these appalling connection protocols not be improved, is there a technical reason? If you're wondering why I'm posting this message, it's because I just spent 25 minutes on hold, and then as soon as the advisor answered, my iPhone XS suddenly went from full strength 4G to no signal, while standing in the exact same spot. I have wi-fi calling, but apparently that didn't help. The call disconnected, I wasted 25 minutes, yet as above simply turning Airplane mode on and off suddenly gave me back full strength signal again! It's infuriating. It seems ludicrous that Jony Ive et al can spend billions of dollars shaving mm of thickness off each iPhone, yet don't seem to care that the devices still don't work reliably.
