It would be easy to imagine that it will be easy, but it's not as straightforward as following the usual procedure. When going from 1.1 -> 1.2 -> 1.3, history of these upgrades was recorded. If the phone is rudely returned to 1.1 and the user asks it to update back to 1.2, it will look at this history and conclude 'I have nothing to do !'. So the way to go in this case is to delete all this history in the lower part of the phone screen by swiping to the right and pushing the red trash button for all theses updates, and then the normal update behaviour will be restored back to normal.

@gpatel-fr Sad! OnePlus usually had superb hardware for the price. Well, at least there is a decent lineup of OP phones that can still be ported.

@gpatel-fr It's really as simple as, if set to English (Canada): Contact: +15145555555 will reliably be found by prediction once I type +151 Contact 15145554444 will not be found no matter what I type Contact (514)555333 will not be found no matter what I type Other contact formats (514) 555-5555, similarly won't be found. Nothing without the initial +. Anyhow, I'm quite happy about the T9! Many thanks to you for making me aware of it, and for your help in diagnosing things. And many thanks to Lionel for creating the function! My extensive (long-winded) testing was to try to be helpful, but I'm quite satisfied with how things function at present. If the phone number predictions get improved for databases as mangled as mine, and various weird international standards, all the better! But sadly, I don't think I'm the person who will succeed with that.

said in What's the return of systemd-detect-virt on your device ?: Edit: created this gitlab issue Well, I researched it a bit previous Sunday and the plot thickens. Looking deeper into phones is staring into the abyss . More in the gitlab issue.

@gpatel-fr Perfect, thank you!
