Samsung Galaxy S20 Network Issues Troubleshooting Guide

If your Samsung Galaxy S20 is experiencing network issues, such as difficulty connecting to a cellular or WiFi network, problems with mobile hotspot, or issues maintaining a cell signal, this troubleshooting guide is here to help you get back online in no time!

Causes of Network Issues

There are several reasons why your Samsung Galaxy S20 may be experiencing network issues. Let’s take a look at some of the most common causes:

Network Hangup

Sometimes, Samsung phones can experience a bug that halts network connection to the phone. This leads to the phone not receiving any mobile data, despite showing an active (and perhaps even strong) connection to the network. To reset your phone’s network connection, simply toggle Airplane mode on for 30 seconds. Upon turning Airplane mode off, your phone should reestablish its connection to the network and fix any hangups you might have been experiencing.

To toggle Airplane mode:

Note that this will usually only solve cellular network connection issues, rather than WiFi issues. To reset a WiFi network hangup, you may need to forget and reconnect to the network.

No Data Transmitted From Source

It’s possible that the reason your phone isn’t receiving data is that there isn’t any data available in the first place. If there’s an issue with your WiFi network or your mobile data provider, your phone won’t be able to receive data through no fault of its own.

You can check that your WiFi network is working by attempting to connect another device to the network. If you are able to connect to the network, try loading a few pages that update frequently to ensure that the device is receiving data from the connection. If the other device is also having trouble connecting or accessing data from the network, you can try to fix the issue by resetting your modem and router.

If resetting your router doesn’t work, get in touch with your internet service provider to ensure there aren’t any outages or shutoffs.

Incorrectly Configured Network Settings

If you’ve been messing around with your phone’s settings recently, it’s possible that you may have changed something you shouldn’t have in the network settings, which is preventing your phone from establishing a solid connection to the network. If you know a bit about network settings, you can try to go back in and fix any mistakes you might have made, but for the uninformed, resetting the network settings on your device should return everything to the functional default settings.

Firmware Malfunction

Sometimes a software or firmware glitch can prevent your phone from connecting to a network. Although a rarer phenomenon, it’s important to rule out before you start opening up your phone and replacing components. You can solve hiccups in the firmware by restarting your phone.

You can restart your phone by holding the power button for three seconds, then tapping the restart button twice.

If a normal restart of the phone didn’t help and you really suspect that a software glitch is what’s causing your network issues, you can go a bit further to perform a factory reset of the phone. This will completely restart the operating system of the phone and eliminate any glitches that may be occurring, but will also clear any settings or data you had, so it’s important to perform a backup of all data you wish to keep before a factory reset.

Faulty Chipset

If nothing else seemed to solve your connection issues, the problem may lie with one of the chips used to make or manage network connections. If your phone experienced a significant impact or water ingress soon before you noticed connectivity issues, it’s likely that your connectivity issues stem from a hardware malfunction.
