Check the result
- An audible ringtone gives a useful distinction from a call-only problem. Record reception and speakerphone differences.
- No ringtone sound or a dimmed speaker control can require service. Do not infer a part number or replacement from this check.
Stop conditions
- Stop using and charging a swollen or damaged battery. Do not open, compress, puncture, or attempt battery removal. Contact the manufacturer or a qualified service provider.
- Disconnect a damaged accessory if it is safe to do so. Do not open a mains power adapter.
- Save accessible data before restarting. Do not reset, erase, flash firmware, bypass a lock, or open the enclosure in this task.
