recover deleted contacts

[matrix77]

I deleted phone contacts few days ago and did not know how to recover  them without root.i have an xperia m4 aqua E2303.maybe someone here knows how to do that.i tried many programs but it does not work without root.i dont want to lose warranty.is there any other possibility to recover?

and another problem with camera,there is an error...the camera is not available.

thanks

If you didn't backed up the contacts you can't recover them, sorry.

but i found many tutorials and i saw that is possible but with root.

@matrix77

if you have root access it "might" be possible, but it's not certain.

[matrix77]

and with root i may lose warranty? depends of what?

i have problem with the camera too

@matrix77

Rooting the phone might delete the data that you are trying to recover.

What camera problems?

[matrix77]

when i open the camera it give me an error ...the camera its not available

and not,i did not make back up before deleting
