Got new Motorola H730. I am not able to mute the phone by pressing both volume keys at once as said in the manual. My phone is Samsung galaxy s7. Any help please?

If you find that your Galaxy S7 is overheating, there are some ways to tackle the problem.

• Go to Settings > Battery > Battery Usage > More > Optimise battery usage, and tap 'All Apps'. Doing this will stop apps from working in the background even when you're not using the phone.

• If overheating persists, you can try wiping the cache partition. With your Galaxy S7 turned off, press and hold the Power, Home, and Volume Up buttons together until you see the Samsung logo and then release. This launches the S7's Android system recovery mode. Tap the Volume Down button to scroll down the list of options and then select 'Wipe Cache Partition' by pressing the Power button.

• If all else fails, a factory reset might be in order. If that proves unsuccessful, it's time to return the S7 to Samsung for a replacement.
