Mobile apps request various permissions during installation, but many users blindly accept them without understanding the risks. These permissions determine what data apps can access, from your location to personal files. While some requests are necessary for functionality, others pose serious privacy threats. Stores like Huawei app gallery (which is quite useful) vet apps for safety, but permission management ultimately lies in your hands. Granting the wrong permissions could lead to data theft, spying, or financial fraud. In this article, we’ll examine six dangerous permissions you should always deny unless necessary, helping you maintain control over your digital privacy.
1. Location Tracking – When to Say No
Risks of Constant Background Location Access
Allowing apps to track your location constantly creates a detailed record of your daily movements, which could be exploited if the data falls into the wrong hands. Some apps collect and sell location data to advertisers, while malicious ones might use it for physical stalking or burglary (by identifying when you’re away from home). Even legitimate apps sometimes request location access when they don’t truly need it— like a calculator or flashlight app. Background location access is particularly concerning as it allows tracking even when you’re not actively using the app.

Which Apps Truly Need Your Location?
Only a handful of app categories genuinely require location permissions. Navigation apps like maps obviously need this access, as do weather apps to provide local forecasts. Ride-sharing and food delivery services also have legitimate needs, but only during active use. Social media apps frequently request location for tagging posts, but this isn’t essential for core functionality. Before granting location access, ask yourself: Does this app’s primary purpose require knowing where I am? If not, deny the permission. You can always enable it later if you find the app isn’t working properly without it.
2. Contacts & Call Logs – A Major Privacy Red Flag
Apps requesting access to your contacts or call history should immediately raise suspicion. This information reveals not just your relationships but also exposes all your contacts to potential spam or scams. Once an app has your contacts, it can upload the entire list to its servers, potentially leading to phishing attacks against everyone you know. Even seemingly harmless apps like games or wallpaper changers sometimes request this permission to build marketing profiles. The only apps that might legitimately need contacts access are messaging and social media apps for finding connections.
3. Camera & Microphone Access – Silent Spying Risks
Camera and microphone permissions are among the most invasive, as they could potentially allow apps to see and hear everything around your phone. While necessary for video calling or photo editing apps, these permissions are often abused. Some malicious apps have been caught taking photos or recording audio without the user’s knowledge, capturing sensitive moments or private conversations. Even legitimate apps might access your camera in the background for advertising purposes. Always deny these permissions unless the app’s core functionality requires them, and consider covering your camera when not in use.
4. SMS & Call Permissions – Avoid at All Costs
How Scammers Use These Permissions
SMS and call permissions are particularly dangerous because they allow apps to read your text messages (including verification codes), send texts without your knowledge, and even make phone calls. Scammers use these permissions to intercept two-factor authentication codes, sign you up for premium services, or send spam messages to all your contacts. Some malicious apps automatically subscribe you to paid services by reading confirmation texts and replying without your consent. There’s almost no legitimate reason for most apps to need these permissions, and granting them could lead to significant financial losses or identity theft.
Legitimate Exceptions (Like Messaging Apps)
The only apps that might genuinely need SMS permissions are default messaging apps (to read and send texts) or banking apps that automatically read verification codes. Even in these cases, Huawei’s permission system allows you to grant one-time access instead of permanent permission. For messaging apps, consider whether you want the app to be your default SMS handler before granting full access. Many users prefer keeping their texting separate from other communication platforms for better security and organization.
5. Storage Access – More Dangerous Than You Think
Storage permissions seem harmless, but give apps access to all your files, photos, and documents. While necessary for apps like photo editors or file managers, many apps request this permission unnecessarily. A malicious app with storage access could steal sensitive documents, delete important files, or encrypt your data for ransom. Some apps scan your storage to build advertising profiles based on your photos and documents. When granting storage access, prefer the “Limited” option that restricts apps to only their own folder rather than your entire storage.
6. Admin/Device Control Permissions
Device administrator permissions are the most powerful and potentially dangerous, allowing apps to perform actions like locking your phone, wiping data, or monitoring screen activity. These permissions are sometimes required by security apps or workplace management software, but should never be granted to casual apps. Once given, these permissions can be difficult to revoke, as some malicious apps hide the option to remove admin rights. If an app requests device admin access, carefully research why it needs this level of control before proceeding.
Conclusion
Protecting your privacy starts with being mindful about app permissions. Always question why an app needs certain access and whether that aligns with its function. Remember, you can often deny permissions initially and grant them later if the app truly requires them. Regularly review permissions in your phone’s settings, revoking any that seem unnecessary. Pay special attention to apps from unknown developers and those with few downloads. By developing these cautious habits, you can enjoy your smartphone’s convenience without compromising your security and privacy. Your data is valuable – guard it as carefully as you would your physical possessions.
