A user's smartphone shows 'Unable to Update' for several apps in the app store, even though the device is connected to Wi-Fi. What is the MOST likely cause?
- AWeak Wi-Fi signal
- BInsufficient storage space
- CAirplane mode is enabled
- DApplication permission not granted
Show answer & explanationAnswer & explanation
Correct answer: B. Insufficient storage space
Since Wi-Fi is confirmed connected, the most common remaining cause of failed app updates is insufficient free storage on the device, which prevents the app store from downloading and installing updates.
Why the other options are wrong
- A. The scenario states Wi-Fi is connected, ruling this out.
- C. Airplane mode would block Wi-Fi entirely, contradicting the scenario.
- D. Permissions affect app functionality, not the update download process.
Mobile App Update Failure
When a mobile app fails to update, the most common cause after confirming connectivity is inadequate device storage.
- Check available storage first
- Clear cache/unused apps to free space
- Update failures with active Wi-Fi point to storage or OS incompatibility
Memory trick: Storage box overflowing — the update can't fit inside
