Calculator Photo Vault
Calculator Photo Vault is a Vault application that can hide photos, videos and other files in a gallery installed on your phone without knowing what a beautiful calculator looks like and works very well. Your files will be secretly stored in the vault and can only be viewed after entering the numeric PIN on this application’s calculator panel.
Undelete Photos With DiskDigger
Install the app DiskDigger Photo Recovery from the Play Store. This is free for photo and video recovery; you only have to pay if you want to recover other types of files.
Launch the app and grant root permissions when prompted. You’ll now see Basic Scan and Full Scan options. Ignore the first one, as it can only find low-res thumbnails of your images. Instead, focus on the Full Scan option.
Find your phone’s internal storage. This is normally the /data partition. Tap it, then choose the type of file you want to search for (likely JPG and/or PNG). Tap OK to begin.
The app starts scanning immediately, and shows you a thumbnail grid of everything it finds. It doesn’t just show your deleted photos—it shows every image in your phone’s internal storage. It thus takes a while to complete.
To filter out some of the findings, tap the Settings icon. Set a larger Minimum File Size—by choosing 1,000,000, for example, you’ll limit your results to images larger than a megabyte. You can also limit the date to a time near when the photos were taken.
DiskDigger can’t find every deleted photo, and some might be corrupted. When it does find the ones you want, select them and tap Recover.
Choose where you want to save the file. You can save them to a specific app, or put them straight back into your camera folder. Choose the DCIM folder to do this. Click OK to save your photos, and you’re done.
Vault: With the help of AES encryption algorithms, encrypt content that you do not want to share with others and support file formats, sizes without restrictions, but also take pictures and recording videos.
Fingerprint Unlock: To provide you with a faster, more secure way to unlock.
