I accidentally deleted photos from my Droid Maxx. How to I recover the deleted photos?
Were they backed up to Google, or Verizon? If they were not backed up and you deleted them from the device, they are likely gone.
For the future, it's simple to set up auto backup of photos and videos to your Google storage. It can be set to happen only over wifi so it doesn't eat your data plan. As soon as you are connected to wifi, backup happens automatically. One Drive is another option (a Windows/MS service but it works with Android as well; I've used both) as is Verizon cloud. I've found One Drive and Google to be more consistently reliable and easier to use than Verizon Cloud. Explore all three and use what works best for you.
