That's useful info on the Android experience... but if it works for anyone, it's still better than Signal's crappy answer to iOS users: "wait until someday when you can trust our new crypto & Intel SGX to upload all your data to a cloud". And yes, WhatsApp has a seamless experience – even if you never share your contact lists, or back-up your message history, to WhatsApp. It "just works" even if you only use encrypted local iOS phone backup/restores – no "unencrypted database in the remote cloud" required. That's why I find Signal's rationale, that "unencrypted remote cloud" is either the "normal approach" or "necessary for recovering the social graph", to be a hand-wavy & borderline dishonest oversimplification. There's a simple approach that works pretty well, including in their major competitor, without the flaws they allege! Debugging an "export to a single file whose format is completely under our control", then "import from that single file" cycle isn't exactly rocket science. But Signal clearly sees their desire to do rocket science as a sufficient excuse for why iOS users (& perhaps per your report, many Android users) can't have any working backup/device-migration solution for 5 years, and counting.
