System apps secretly collect your data on Android Stop Your Phone From Sharing Data— even when you deny permissions. Learn how to stop your phone from sharing data with system apps without root in 2025.
Your Phone Is Spying — Even Without Permissions
Even if you turn off app permissions on Android, your phone’s system apps — like Google Play Services, System UI, and MIUI Analytics — continue to collect your private data.
They can:
- Access your location, device ID, app usage, and network logs
- Share data with Google, OEMs, and third parties
- Run silently in the background
Worst of all, you can’t uninstall most of them — and rooting your device can break features or void warranty.
But the good news?
You can stop most system data sharing without root.
This Digimad guide shows you how — step by step.
What Data Do System Apps Collect?
System apps are deeply integrated into your phone. They often collect:
- Location history (even when GPS is off)
- IMEI, SIM info, and device fingerprint
- App usage patterns (what apps you use and when)
- Clipboard contents
- Crash logs and analytics
All this data is used to:
- Show you personalized ads
- Feed analytics to manufacturers
- Share with Google or cloud sync
Signs Your Phone is Sharing Data in Background
- You receive ads about places you visited
- Battery drains faster than usual
- Data usage increases even when phone is idle
- You see notifications like “System UI used location”
- Sync or backup options are turned on without consent
Step-by-Step Guide: Stop Data Sharing With System Apps (No Root Needed)
Step 1: Disable Usage & Diagnostic Reporting
Android collects device info, crash logs, and usage patterns. Here’s how to stop it:
- Go to Settings → Google → Usage & Diagnostics
- Toggle it Off
This blocks sending analytics to Google and system-level apps.
Step 2: Revoke “Usage Access” for System Apps
System apps track how long you use each app. Turn it off:
- Go to Settings → Apps → Special App Access → Usage Access
- Revoke access for:
- Google Play Services
- System UI
- Digital Wellbeing
- Analytics or feedback apps
Now they can’t monitor your app activity.
Step 3: Turn Off Ad Personalization
To block data sharing with advertising systems:
- Go to Settings → Google → Ads
- Enable “Opt Out of Ads Personalization”
Also tap “Reset Advertising ID” to wipe your profile.
Step 4: Use NetGuard (No-Root Firewall)
NetGuard creates a local VPN that blocks internet access per app.
Steps:
- Download NetGuard from F-Droid
- Enable NetGuard
- Block apps like Google Services Framework, Feedback, MIUI Analytics
Now, even if system apps run, they can’t send your data out.
Step 5: Use Exodus Privacy App
Want to know which system apps have hidden trackers?
- Install Exodus Privacy from F-Droid
- Scan system apps
- Identify analytics/advertising trackers
- Avoid or disable apps with suspicious trackers
Step 6: Limit Background Activity via Developer Options
This reduces what system apps can do silently:
- Enable Developer Mode: Settings → About Phone → Tap Build Number 7x
- Go to Settings → System → Developer Options
- Enable these:
- Don’t keep activities
- Background process limit → At most 2 processes
- Restrict background apps
Step 7: Disable Location for System Apps
Many system apps don’t need your location. Remove it:
- Go to Settings → Location → App Permissions
- Tap “See All Apps”
- Deny access to:
- Google Play Services
- Weather apps
- System UI
- Analytics services
Also turn off:
- Wi-Fi scanning
- Bluetooth scanning
- Improve Location Accuracy
Step 8: Use a VPN with Tracker Blocker
Use a VPN that protects from DNS-level leaks and trackers.
Top options:
- Surfshark: Built-in CleanWeb tracker blocker
- Mullvad: Strong anti-tracking, no logs
- ProtonVPN: Strong encryption, open-source, no logs
Install your VPN → turn on tracker protection → stay invisible.
Step 9: Turn Off Sync & Backup
Google and OEM services often sync your:
- Contacts
- App data
- Device settings
- Activity logs
To stop:
- Go to Settings → Google → Backup
- Turn it OFF
- Also go to Account Sync → disable everything unnecessary
