HDR - backup

[emk]

First, I don't know how to turn HDR on camera
Second, every time I switch off my phone for a week or something (cause I use different phone) and then switch it on, a lot of pics are gone
Although, I backup the phone before I switch it off every time!
Any ideas?

What happens with the contacts?
I can't edit any of them
They keep returning back
I once mistakenly typed a name and saved it and I can't edit it, every time I change it, it returns back to the wrong name
And it's also never changed on whatsApp

If you use pictures from internal memory, does the same problem occur?

[emk]

Do you mean pictures for the contacts?
Or the pictures on the album ?
Cause the pictures on the album sometimes disappear
P.s I save almost everything on the SD card

For the contacts, didn't you say those dissapear? I think SD card is the reason why your photos go missing too.

How come!
The contacts are on the phone memory.

I thought pictures for contacts dissapear.
