The Samsung Galaxy J3 has more than a few problems, but one of its biggest issues has to do with blank screens and silent phone calls. This could either mean someone you’re talking to can’t hear you, you can’t hear them, or the screen just goes dark during a call and nothing happens.
There are a few different reasons why this problem can happen, and I’ll go through each and every one until you find a solution that works for you. The call problem could be because of a faulty case, a covered speaker, your proximity sensor, or even how you hold your Android. Hopefully your Galaxy J3 will start taking calls normally before you even get to the end.
1. Disable Your Proximity Sensor
If you’ve already gone through most of the basic troubleshooting steps, then it’s time to look at a few things about your phone that might be the problem. The Samsung Galaxy J3 has a proximity sensor on the device so it knows when to turn off certain functions to save battery, but unfortunately it doesn’t always work as intended.
If this is what’s causing the problem for you during calls, then it’s much easier to just turn it off. To turn off your proximity sensor:
- Tap the Phone icon
- Tap the Menu icon
- Go to Call settings
- Find the setting to turn off screen during calls and disable it.
Additionally, give the 3.5mm jack in your phone a quick blow of air. This will sort a few things out if disabling this option didn’t. This will help stop your screen from dimming or going completely blank during a call, but it won’t necessarily solve the silence problem.
2. Observe How You Hold Your Phone
When you’re talking on your Galaxy J3, how do you hold your phone? I know that whenever I’m talking on the phone for more than a few minutes my hands start to shift. I’ll sometimes press buttons, cover up something important, or hold it at the wrong angle if I’m not careful.
Make sure that during a call if the quality worsens, or your voice drops, that you’re holding it the same way you were when the call started.
3. Remove Your Case
Depending on the case you’re using, it can worsen your connection, or ability to send or receive calls properly. While trying to pin down what about the case is causing the problem, it’s easier to take the whole thing off.
Try taking a call again with your case off and see if it stops your Galaxy J3 from forcing you to stay silent.
4. Clear Your Cache
Clearing your cache is a part of the basic troubleshooting that I mentioned earlier, but can’t hurt to clear it again.
It doesn’t take long to do, and saves a lot of headaches down the road.
5. Use an External Mic
If you’ve ever considered using a Bluetooth headset for your Galaxy J3, now’s the perfect time to try one out and see if your built in microphone is the problem. If you want to test your microphone beforehand without making a phone call, try recording a voice memo to yourself and seeing if you can hear it afterwards.
Depending on the result, buying a new microphone to use doesn’t fix the problem itself, but it does make your phone usable again. Any Bluetooth mic will work, but if you have an OTG cable handy, a USB mic works just as well. It isn’t nearly as portable, but it’s a quick solution.
6. Perform a Factory Reset
This is one of the last possible options you have, but it’s the easiest way to tell the difference between a software and a hardware problem. If a factory reset doesn’t fix the issue, then there’s a fundamental flaw with your Samsung Galaxy J3 that can’t be fixed easily.
Before you attempt a factory reset, I cannot stress enough that you need to backup all of your important data. Once you’ve made sure you’ve recovered everything you’re about to delete, take a deep breath, and factory reset your device.
More often than not, the problem here is going to be the proximity sensor. It’s easy to see if that is the problem after you turn it off, but if it isn’t, there’s still more to try. The problem does have a fix, it just takes time for troubleshooting to do its job.
