Press and hold the Power button for a few seconds until the Power menu appears. Tap Power off, and then tap Power off again to confirm.
On phones without a dedicated Power button, swipe down with two fingers from the top of the screen to open the Quick settings panel. Tap the Power icon at the top of the screen, and then tap Power off. Tap Power off again to confirm.
Once the phone shuts down, wait 30 seconds, and then press the Power button to power on your phone.
Audio problems can occur if there is water in the speaker. If your device has gotten wet, dry it off right away and try to remove as much water as possible. Be sure to pat the earpiece (at the top front of the phone), the primary microphone (at the bottom of the phone), external speaker (also at the bottom of the phone), and the USB port with a clean, soft cloth.
Do not expose the phone to salt water or ionized water. If your phone is exposed to salt water, wash the phone with fresh water, and then dry it thoroughly with a clean, soft cloth. Otherwise, when it dries, salt may accumulate and block the primary microphone, earpiece, or external speaker.
The speakers may sound quiet, crackly, or distorted if the phone has recently undergone a large change in ambient air pressure. This is a due to the water resistant features of many Galaxy phones.
In most cases, the pressure will equalize over time, however you can speed the process along by temporarily opening the SIM tray.
Insert your SIM tool into hole one the SIM tray and carefully slide the tray out about halfway. It only takes a moment for pressure to equalize, so you can immediately close the tray.
Use the Volume buttons while playing music to ensure the sound is not muted. If the sound quality is fine, then your speaker is working normally.
You can also run the diagnostic tests in Samsung Members.
You can also check for updates using Smart Switch.
If you were having issues before the software update, use the phone or tablet normally to check if the problem has been solved.
Certain downloaded apps can make your phone or tablet freeze, crash, or lag. Some apps can even affect camera functionality, cause audio issues, and affect network connectivity.
Using Safe mode disables all downloaded apps and loads only the original software that came with your phone or tablet, allowing you to determine if the issue is caused by an app or with the device itself.
If the issues do not appear while in Safe mode, the problem is caused by a downloaded app, and it should be uninstalled.
First, open the Power menu:
Touch and hold Power off until the Safe mode icon is displayed. Tap Safe mode to start your device in Safe mode. If you've entered Safe mode successfully, you'll see “Safe mode” displayed at the bottom of the screen.
Use the phone or tablet normally to see if the issue has been resolved. If the phone or tablet is operating normally, a recently installed app was most likely causing the issue.
One by one, uninstall any apps you downloaded just before your phone or tablet began having the issue.
From your Home screen, swipe up to open the App drawer. Find the app you want to remove, and then touch and hold the app's icon until a popup menu appears. Tap Uninstall, and then tap OK to confirm.
After uninstalling each app, exit safe mode and check for normal operation.
After you uninstall the app that caused the issue, you can reinstall the other safe apps you just deleted.
First, open the Power menu:
Tap Power off to turn off the device. Wait until the phone or tablet completely turns off, and then press the Power button again to turn it on. Check if the issue has been resolved.
Make sure to back up your phone or tablet. All data and settings will be erased.
Write down the username and password for the account that you used to back up your data.
We recommend having your phone or tablet plugged into the wall charger during the reset process because it may take up to an hour.
If you have encrypted the SD Card inserted in to your phone or tablet, make sure to decrypt it before the reset. Navigate to Settings, search for and select SD, and then tap Decrypt SD card.
Before installing any apps, make sure that your phone or tablet is functioning normally.
If you are still encountering any issues, please visit a Samsung walk-in service center or you can schedule a repair service online.
