LinkedIn mobile app upgrade failure: diagnosing data persistence after a partial install

Problem Statement

When a LinkedIn mobile app update is interrupted—due to network loss or insufficient storage—the device may retain a partially downloaded package while the previously installed version remains active. This situation risks corrupting local cache or losing session data, yet the app’s current behavior appears to rely on user‑initiated retry rather than an automated rollback.

The goal is to understand how LinkedIn manages data integrity during such failures, what safeguards are in place to detect a corrupted install, and whether the app can automatically restore the last known good state.

Key questions:

1. What mechanisms does LinkedIn currently implement to detect a partially applied update and trigger a rollback, if any?
2. Does the app preserve user credentials and cached content when an update fails, or is there a risk of data loss?
3. If a rollback is not automatic, what is the recommended strategy for developers to recover cleanly without user intervention?
