Hey. There are several things that we can try to get your volume to do what it's supposed to do.
Clearing your Cache
The system cache partition stores temporary system data. It's supposed to allow the system to access apps more quickly and efficiently, but sometimes things get cluttered and outdated, so a periodic cache clearing can help make the system run more smoothly. - When the Android logo displays, release all three keys. - An ‘Installing system update’ message will show for 30 – 60 seconds before the Android system recovery menu options appear. - Press the Volume down key several times to highlight wipe cache partition. - Press Power key to select. - Press the Volume down key to highlight yes, them and press the Power key to select. - When the wipe cache partition is complete, Reboot system now is highlighted. - Press the Power key to restart the device. Your phone will take a little time booting up after the cache partition is wiped off of its contents as it will rebuild or recreate those caches. Don’t be alarmed if the phone gets stuck on the logo for a minute or two after this just don’t turn it off so that what was deleted will be replaced successfully. So, wait for your phone to become active. Don’t worry, this procedure is very easy and safe to do. You won’t damage your phone just by wiping the cache partition.
Check for software updates Check if there are any software updates for your phone or tablet by navigating to Settings, and then tapping Software Updates or System Updates. If an update is available, install it by following the on-screen prompts.
Reboot the phone in Safe mode
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 phone or tablet.
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:
On devices with a regular Power key, press and hold the Power key until the Power menu is displayed. On devices without a dedicated power button, swipe down with two fingers from the top of the screen to open Quick settings. Tap the Power icon at the top of the screen. 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.
Factory Reset
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.
Perform a factory data reset. Navigate to Settings. Search for and select Factory data reset. Tap Factory data reset again, and then tap Reset. Follow the on-screen prompts to complete the reset. You may need to enter your Samsung account password or Lock screen password. The phone or tablet will reboot.
If this does not help I recommend letting a service technician have a look. As we would like to gather additional information, and look at this from a case by case basis, please provide the full model code and serial number of the device as well as your best contact phone number, name, and email.
