Hi,
We insiders knew that the SMS backup/restore system had some hiccups in W10M, especially between build 10549 (IIRC) and above (10572). Between these 2 builds, Microsoft have changed the architecture of SMS saving and restoring:
a) before 10572 (10549 and below, including WP8.1), SMS were restored sms by sms, in chronological order
b) after 10572 (including 10572), texts are restored by thread (contact A entirely, then contact B, etc.)
BUT. Since December, we were many insider noticing that only some messages are restored. Some gaps were observed, or hit and miss sync (a 8 SMS conversation was instantly synced the same day on another device, but with 2 or 3 SMS missing).
But then we were insiders.
My only devices now are: Lumia 950 (main phone, with my 2 SIMS) and Lumia 535 (simless). The 535 was flashed to 8.1 last Friday and upgraded "properly" to 10. SMS are starting to restore slowy today only.
And I got only one thread back at this stage: my wife's one. All messages are there up to 5th of June 2015. Then nothing until this Monday, and it's mainly my messages, 70% of hers are missing.
Microsoft are TOTALLY silent about this issue. I wouldn't fuss if we KNEW that all SMS are saved systematically, but they fail to restore. But we're not even sure of that. Maybe some SMS fail to be saved in the cloud, and then, are lost forever.
Contacts+backup is a nice app, but not adapted to dual sim devices.
Have you hit this issue too? Comment below.
I find it very rude, from MS, to allow W10M upgrade when their SMS backup process is NOT reliable. Because non Insiders are genuinely upgrading their devices to W10M, thinking it's better, and they may lose memories, or SMS, in the process.
