Appendix

The battery does not charge properly (For Samsung-approved chargers)

•Ensure that the charger is connected properly.

•If the battery terminals are dirty, the battery may not charge properly or the device may turn off. Wipe both gold-coloured contacts and try charging the battery again.

The battery depletes faster than when first purchased

•When you expose the device or the battery to very cold or very hot temperatures, the useful charge may be reduced.

•Battery consumption increases when you use messaging features or some apps, such as games or the Internet.

•The battery is consumable and the useful charge will get shorter over time.

Your device is hot to the touch

When you use apps that require more power or use apps on your device for an extended period of time, your device may feel hot to the touch. This is normal and should not affect your device’s lifespan or performance.

If the device overheats or feels hot for a prolonged period, do not use it for a while. If the device continues to overheat, contact a Samsung Service Centre.

Error messages appear when launching the camera

Your device must have sufficient available memory and battery power to operate the camera app. If you receive error messages when launching the camera, try the following:

•Charge the battery.

•Free some memory by transferring files to a computer or deleting files from your device.

•Restart the device. If you are still having trouble with the camera app after trying these tips, contact a Samsung Service Centre.
