Photos and music from internal storage got deleted. How to recover them? I restarted my LG Android phone and it was supposed to back up my phone's memory – but it deleted my photos and music that was saved to my phone's internal memory.

How do I get my music and photos back?
I will guide you with the process of getting your pictures back. (For music I would say you always download them again from their original source). Additionally to your device, this procedure will require a Windows or Mac computer/Laptop and an USB cable.


I am going to guide you over here with the help of Dr. Fone for Android by Wondershare. So download and install it over your PC/Laptop. 
Connect your device with your PC/Laptop with the help of USB cable. Also make sure that USB debugging is enabled over your device. If the USB debugging isn’t available then you can always enable USB debugging under Developers option available under setting. You'll see a notification at the bottom of the screen saying that USB Debugging is being opened in the Dr. Fone Software over your PC/Laptop.
Once the connection has been made you will be able to select categories of deleted files i.e Photos, Contacts… etc ! Tap over the category you want to recover! Next Step is to tap over the Scan button for deleted files and follow the options appearing on the screen!


  Note: You'll need to accept the RSA key prompt on your smartphone (check ''Always accept'' to make it easier), making the connection between the two devices secure.
  Once it will analyze your phone. There will be reboots, don’t be panic and let the tools do what its doing. Now you’ll get the scan results where you can tap over the check box for the photos you want to recover, so click over it and hit the recover button. And you will get your pictures back! 
  
  Hope this time my post helps you in getting your photos back!
