When you install an app on an Android device, you control app permissions. Permissions allow you to choose which capabilities or info an app can use. Learn how to change app permissions.
Harmful apps might ask you to change settings that put your device or data at risk. To protect you from harmful apps, some device settings may be restricted when you install an app. These restricted settings can’t be changed unless you allow restricted settings.
How to identify a scam
Scammers use various methods to trick people into downloading harmful apps to get to their personal data. Consider the following example scenarios to determine if an app could be a scam.
You’ve been contacted out of nowhere
Unexpected messages should raise suspicion. Fraudsters often send convincing text messages or emails. For example, they may claim that you have a missed delivery or voicemail.
The app insists that you change a device setting
Apps typically explain why a permission or setting must be changed before it asks you to change them. Requests made by harmful apps are often unexplained or don’t make sense.
It’s too good to be true
Harmful apps might claim to improve the performance of your phone or offer content that you'd expect to pay for. If it sounds too good to be true, it probably is.
There are spelling and grammar mistakes
Messages and apps that have spelling and grammar errors are likely to be from scammers. Legitimate organisations will rarely make these mistakes when they contact you.
When you enable restricted settings, you allow apps to get access to sensitive info that could put your personal data at risk. We don’t recommend that you allow restricted settings unless you trust the app developer.
Some legitimate apps might ask you to enable restricted settings. For example, an app that’s designed to support people with disabilities might ask you to turn on accessibility settings. With access to accessibility settings, the app can read content on your screen and interact with apps on your behalf.
On your Android device, open the Settings app.
Tap Apps.

A restricted call is when someone wishes their number to be blocked from being revealed through caller ID, and so they restrict it from caller ID identification.
Signal restriction often occurs when bills are unpaid. See if all your bills are clear and check your spend manager to see if your call, text or data limit has not been crossed. Rarely, it is a sim or account fault that is easily resolved by calling customer service.
