One of the most common problems Galaxy S4 owners is related to signal reception. While the gravity of the problem may vary depending on the quality of signal your carrier transmits from its towers, more often the problem originates from within the phone. If it were case, there may be some settings you need to change to solve the issue.
It is difficult to pinpoint where and how the problems started or what caused it that is why owners who have basic technical knowledge are advised to do some troubleshooting procedures to diagnose the issue. If you’re currently experiencing this problem, here are some of the things you can do to diagnose or even resolve the issue.
Check the Airplane Mode. The Airplane / Flight Mode was specially customized so the phone cannot interrupt communications that come in and out of an aircraft. Basically, all communication services including mobile data network connectivity are disabled when the phone is placed in this mode. It is wise to check if the Airplane mode was enabled when the device scarcely or doesn’t receive signal.
From the Home screen, hold the Power button.
Touch Airplane mode.
You’ve now disabled/enabled Airplane mode.
If this doesn’t solve the problem, move on to the next step.
Check network coverage. Check with your friends who have subscribed to the same carrier you subscribed to know if it’s a network problem. If it is, then the problem should be resolved in the next couple of hours or so unless some serious events that may have disrupted the service happened in the vicinity near you. You can also call technical support to inquire or to report the service disruption.
After checking and you are sure the problem is not with the network, try to go outside your home to see if you can get better reception. If you can, then the problem is not with the phone. Otherwise, proceed to the next step to continue troubleshooting.
Reboot / Soft Reset your phone. For sure, your phone is still under warranty so the only thing you can do with it, at least for now, is to do a soft reset.
Turn off your phone.
Take the battery off for 1 minute.
Reinsert it and turn the phone on.
Check if it’s receiving signal.
Have a technician check the phone. Go to an authorized service center or your provider and have the device checked by a technician. Your carrier or provider may replace the phone with a new unit if the tech guy can’t solve the problem. At least, that’s one thing a carrier can retain its customers with problems with their devices.
For problems like this, never ever let unauthorized technicians to pop the device open as you may end up voiding your warranty. You also don’t need to flash custom ROMs or root the phone.
