Okay, back again. Although much more stable I still get irregular
self-restarts. An O2 Guru has forced the Android update again but still
getting restarts.Visit to Guru booked for tomorrow where I expect phone
will get a master reset.
Yes, it's working again now. I guess the reboot occurred around 20 times
before it stabilised and now stays on. Another guess is that there was
some unfinished Upgrade still running in the background which eventually
finished. I had no need to Reset ...
