mSpy-like monitoring software can run normally when first installed, but after the phone is locked and left idle for a while, data may stop updating. Many people assume it's a network or server issue, but the real cause is often on the phone side: mSpy is essentially a regular Android app, and Android does not guarantee that regular apps can stay in the background indefinitely.
Root Cause: Regular Android Apps Are Stopped by the System
After an app leaves the screen, Android gradually restricts its background execution. The longer the phone is locked, the more likely the system will shut it down to save power or free memory. Some manufacturers even actively clean up apps that have not been opened for a long time.
mSpy's Problem: No Restart Entry After Being Stopped
The most straightforward way to restore a regular app after it is stopped is for the user to tap the desktop icon to reopen it. Another way is to be launched by another app. To hide its presence, mSpy hides its desktop icon. mSpy's official documentation clearly states that after installation, no visible icon appears on the target phone. While this reduces the chance of detection, it also removes the simplest manual restart entry: once the app is closed, the device user cannot restart it by tapping an icon. To solve this, mSpy would need help from the phone manufacturer or another long-running app to restart it. As of the publicly available information consulted for this article, mSpy does not indicate that such cooperation exists. This creates a difficult-to-recover state:
- mSpy is stopped by Android after being left in the background;
- The desktop icon is hidden, so the user cannot manually open it;
- No other app helps it restart.
This is why mSpy-like software may stop updating after one or two hours. The problem is not necessarily with the control panel or server, but that the app on the phone has been closed and lacks a reliable restart entry.
Why Teralivo Is Different
Teralivo does not require installing an app; instead, it uses ADB technology to directly start a background service. Android does not manage Teralivo as a regular app, so it is not affected by power-saving, background cleanup, or force-stop rules. Teralivo's oom_score_adj is -1000, placing it at the same protection level as Android core processes in memory reclamation priority. Therefore, even if the phone is locked for a long time or memory is tight, the system will not shut down Teralivo like it would a regular background app, allowing it to run in the background long-term like a system process. This value can be checked by reading /proc/self/oom_score_adj. As a result, Teralivo can continue running after the phone is locked and in long standby, without losing connection due to power-saving, standby groups, force stops, or routine memory reclamation like regular background apps.
Core Differences Between the Two Operating Mechanisms
| Comparison Item | mSpy-like Regular Android App | Teralivo |
|---|---|---|
| Launch Method | Install and launch as a regular app | Start a background service via ADB |
| Background Running | May be closed by power-saving and background cleanup | Not affected by regular app management |
| Recovery After Stop | Relies on desktop icon or another app to help restart | Does not stop, so no recovery needed |
| Desktop Icon | mSpy official documentation says it hides the icon | Does not rely on desktop icon for launch |
| Low Memory | May be closed by the system | oom_score_adj is -1000, will not be cleaned |
Points to Note
Regardless of the solution used, it can only manage devices that you own or for which you have obtained explicit, legal authorization. You should also inform relevant individuals about the data collected, its purpose, and retention period.
