Get rid of "What's New"

[prefixus]

Solution marked as solution DOES NOT WORK!

It does not remove notification that show again on the phone.

Sony if you cannot remove this app just tell why.

This is the most annoying thing I have seen on any Android phone ever.

I do not have WhatsNew present on my phone (uninstalled using adb) but I'll try to help you using WhatsApp and Camera Roll as an example.

Goto the apps page-> long press on the WhatsApp icon (hey did you notice you can place a WhatsApp widget on the home screen?) -> tap on the i sign-> you will find a menu with notifications on top and an abundancy of settings.

When doing so with another app like Camera Roll you will find File Operations under Advanced.

Tapping on File Operations will show a new menu where one of the choices is:

On the lock screen, Show all content.

What I'm trying to say is that it is worth the time to check out what settings are present in different apps.

@Lorne_

About using adb to 'uninstall' WhatsNew:

Android studio is way too hughe for this purpose.

Try Minimal ADB and Fastboot, released by Google.

Update

I installed whatsnew to check.

Long tap on the whatsnew icon

Tap on i

Tap on notifications

 Does that help to suppress WhatsNew?
