Locking Emails on Samsung Galaxy S3 I have a Samsung Galaxy S3. I use the build-in Email application to access my email from my internet service provider (so this is NOT gmail, outlook etc.).

I am often on the road and I need access to my emails. However, I want to maintain the confidentially of the emails i.e. I don't want anyone else to open and read my emails.

I know I can lock my phone but I prefer to only lock the email application. In this scenario, I have no problem with anyone accessing my phone and looking at photos etc. It is just that I don't want them to have access to my emails.

Is there a way to lock the email application only so that if I want to access my emails, I will have to provide a password etc.

The emails I am referring to above are business emails, so I need to keep most of them confidential.
There's lots of apps that perform the function of restricting access to other apps. Simply head to Google Play and search for "app locker".
