Ways to resolve Samsung Smart TV Apps issues

1. Perform a Power Cycle on the Devices

Generally, restarting solves common problems.

To do this:

• Unplug the power cords from the wall for your modem, router, and TV. Do not disconnect any Ethernet cables.
• Plug in the modem and router first, waiting for it to establish a connection.
• Then plug in the TV and turn it on.

2. Perform Internet Network Test

Carry out a Network Test on your Samsung Smart TV to check its internet connection.

To do this:

• Push the Menu button on your remote control.
• Chose Setup from the list.
• Go into the Network option.
• Then select Network Test in the Network Menu.
• The Test will now initiate on your Smart TV.
• When it's successful, the parts of the Test will all show a check mark.

3. Enhance Network Efficiency

• Disconnect any other unused devices that have been connected to the same network. Moreover, the quality of the Wi-Fi signal may be affected either by the proximity of the device to the router or by other environmental factors.
• Consider moving the router to a central location in the room or employ a Wi-Fi extender. 
• Furthermore, for the best connection possible, using an Ethernet cable is the most ideal option.

If this does not resolve the issue, then you will need to update your TV's Firmware.

4. Restart your router and modem

A simple restart can often fix minor internet connection problems. 

To restart your router and modem:

• Simply unplug them from the power outlet for 30 seconds.
• Then plug it back in.

5. Perform Samsung Smart TV Software Update

The most effective way to update your Smart TV's firmware is to use the Web and have your TV connected to the Internet through Wifi. Doing this will improve existing features, fix any bugs, and sometimes even add extra applications to your TV.

To do this:

• Press the Menu button on your remote control.
• Then, Select Support.
• Now, Select Software Update. If the option to return to using your TV is greyed out, it may be because you have just switched the TV on (wait a minute and try again) or you are in Smart Hub mode. If you have gone into Smart Hub mode, exit back to a TV channel after viewing. 
• Next, Enable Auto update so that you always receive the latest updates.
• To check for a manual update, select Update Now.
• Your TV will scan for updates.
• Choose Yes if an update is found to download and install it.
• Once the update is finished, you can go back to using your TV.
