How to fix Galaxy A80 won’t connect to 4G LTE
Although it’s rare that Samsung Galaxy devices fail to connect to 4G network, it can still happen. If you are one of the unfortunate few users whose Galaxy A80 won’t connect to 4G LTE, follow the steps below to fix it.
A80 won’t connect to 4G LTE fix #1: Check for 4G or LTE signal
Before you begin troubleshooting your device, the very first thing that you want to do is to ensure that your Galaxy A80 shows it’s detecting 4G or LTE signal. This is important if the problem happens only recently. If the phone was working with 4G fine before this, it’s possible that there may be a network issue. Although it’s not unheard of, some phones may sometimes lose 4G functionality if it’s hardware is damaged, or if it’s software encounters a glitch. If 4G LTE was working in the same area before, there can be an issue with the network or with the phone. Your first troubleshooting step is to determine whether it’s a network problem.

If your A80 shows no 4G signal right now, try to insert the SIM card to another compatible phone (that’s connected to the same network) and see how it goes. If the second device still shows the same result, then you can assume that your A80 is fine and problem is coming from the carrier itself. What you can do in this case is to either wait until the problem goes away, or you can contact the network operator so you can get first hand information from them about the outage.
A80 won’t connect to 4G LTE fix #2: Refresh the system
Sometimes, phones may be unable to reconnect to the network on its own. Although Samsung has not released official explanation why this is, the phenomenon has been observed in many Samsung Galaxy phones before. Apparently, the phone can’t automatically detect and use 4G LTE in some cases. This doesn’t mean there’s a network issue since most of the time, the issue goes away on its own, or when the phone is restarted. This is clearly a coding or hardware issue that Samsung has not figured out how to fix. What you can do in this situation though is to simply restart the phone and you should be good. This is basically a restart with the aim of clearing the system by simulating the effects of a battery pull. To do that, simply press and hold the Power and Volume Down buttons for about 10 seconds. Once the phone has restarted, release the buttons. This is usually effective in clearing bugs that developed when a system is left running for some time. We suggest that you restart your A80 using this method at least once a week to lessen the chances of bugs.
For some Galaxy A80, there may be a slightly different way to arrive at the same method. Here’s how:
- Press and hold the Power + Volume Down buttons for approximately 10 seconds or until the device power cycles. Allow several seconds for the Maintenance Boot Mode screen to appear.
- From the Maintenance Boot Mode screen, select Normal Boot. You can use the volume buttons to cycle through the available options and the lower left button (below the volume buttons) to select. Wait for up to 90 seconds for the reset to complete.
A80 won’t connect to 4G LTE fix #3: Change network mode manually
In older Galaxy devices, we noticed that forcing devices to connect to a slower network mode like 2G or 3G then back to 4G sometimes correct the problem you’re experiencing. We recommend that you try doing this simple troubleshooting step to see if it works. It’s easy to do. Follow these steps to do it:
- Open Settings app.
- Tap Connections.
- Tap Mobile networks.
- Tap Network mode.
- Depending on your options, you should select the one that indicates 4G or similar to this: LTE/3G/2G (auto-connect).
- Restart the device and check for the problem.
A80 won’t connect to 4G LTE fix #4: Reset network settings
If the problem occurred out of the blue after an update or changing some settings, it’s possible that there may be a network configuration issue going on. To ensure that your Galaxy A80 has the right network setup, you want to clear the current settings. This is usually helpful in fixing minor network bugs. Here’s how it’s done:
- From the Home screen, swipe up on an empty spot to open the Apps tray.
- Tap General Management > Reset > Reset network settings.
- Tap Reset settings.
- If you have set up a PIN, enter it.
- Tap Reset settings. Once complete a confirmation window will appear.
A80 won’t connect to 4G LTE fix #5: Wipe cache partition
Samsung Galaxy phones use a special kind of cache called system cache to load apps quickly. This cache is composed of many different types of files that the system uses to efficiently load things up. Sometimes, this cache may get corrupted after an update, app installation, or by malware. The thing is, once this cache becomes corrupted, there’s no telling what bug may develop. In most cases, the system may bog down or become slow. In some other cases, basic functions or apps may become problematic. To ensure that you have a good working system cache, we suggest that you clear the cache partition, where it’s being kept, once every few months. This can also be a good troubleshooting step in this case. To clear the cache partition:
- Turn off the device.
- Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
- When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
- Press the Volume down key several times to highlight ‘wipe cache partition’.
- Press Power button to select.
- Press the Volume down key until ‘yes’ is highlighted and press the Power button.
- When the wipe cache partition is complete, “Reboot system now” is highlighted.
- Press the Power key to restart the device.
A80 won’t connect to 4G LTE fix #6: Install updates
Keeping the software environment of your Galaxy Tab S5e up-to-date is important. Not only do updates bring cosmetic changes but they also fix known bugs. Although not generally known by many Android users, installing updates sometimes also bring needed fixes for known bugs. Make sure that you don’t delay the installation of any system or app updates. By default, your tablet should notify you of any available updates but in case you turn this mechanism off, it’s high time that you manually check for them.
To check for Android or system update:
- Open Settings app.
- Tap Software update.
- Tap Download and install.
- Wait for the device to check for updates.
- Install the update. If there’s no new update, your phone should tell you so.
For carrier-branded Galaxy A80 devices, or those that were provided by your carrier, there may not be an option to manually check for updates. All you have to do is to simply confirm if there’s a notification for an update and allow update installation.
To check for app updates:
- Open Play Store app.
- Tap More settings icon (at the upper left).
- Tap My apps & games.
- Tap Update all button.
A80 won’t connect to 4G LTE fix #7: Check for rogue apps
Some Android apps may sometimes cause problems with other apps or with the Operating System. To check if one of the installed apps is interfering with the system and causing the Galaxy A80 won’t connect to 4G LTE issue, try restarting to safe mode. Here’s how to do that:
- Press and hold the Power button until the Power off window appears then release.
- Touch and hold Power off until the Safe mode prompt appears then release.
- To confirm, tap Safe mode.
- The process may take up to 30 seconds to complete.
- Upon reboot, “Safe mode” appears in the lower-left of the home screen.
Remember that third-party applications are disabled in this mode so what you can use are pre-installed apps. If the touchscreen issue won’t appear on safe mode, that means that the problem is due to a bad app. Uninstall the app you recently installed and see if that will fix it. If the problem remains, use the process of elimination to identify the rogue app. Here’s how:
- Boot to safe mode.
- Check for the problem.
- Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
- After you uninstall an app, restart the phone to normal mode and check for the problem.
- If your A80 is still problematic, repeat steps 1-4.
A80 won’t connect to 4G LTE fix #8: Factory reset
If the problem remains at this point, the final step that you want to perform is factory reset. As the name suggests, it will clear phone software settings and return them to their factory defaults. This is usually effective in fixing configuration or settings issues. If there’s a software bug that we’re not aware of, factory reset might bring your A80 back to its working order.
Below are the two ways to factory reset your A80:
Method 1: How to hard reset on Samsung Galaxy A80 via Settings Menu
