I was replying to a post on the Phones board about someone wanting to recover Contacts from a dead phone.
Having almost had that happen to me, I found that with an Android phone you can save ALL your contacts to the SIM card.
Open Contacts - the 3 square menu thingie 🀫 🀫 🀫 - Export Contacts - Export To SIM Card
Then if you get a new device you can put in the SIM, and Import your contacts through a similar process.
The one negative is that the backup is manual, though you can choose the option to save a New Contact to your SIM.
The positive is that you have an excuse to go through your contacts and say ' why do I still have HIM on here'
You can also save to a SD card if you have one in your phone. And you can save your pictures there too. For those pictures you don't want to trust to the Cloud. 🤐
Not sure how it works with Apple. That's her phone, I stay away from it.
