How to turn up the microphone in the Samsung Galaxy J7 Crown

I’m not an android expert, and I’m also not an expert smartphone user. Despite my inexperience, I discovered an easy process of how to turn up the microphone in the Samsung Galaxy J7 Crown smartphone.

The process is fast, and only takes two minutes. My guess is that this simple process should work for all Samsung Galaxy models.

Why doesn’t my smartphone microphone work?

I recently bought a new Samsung Galaxy J7 Crown smartphone. It’s the best smartphone I’ve ever had — it seems the Samsung Galaxy models continue to improve.

After only a month of light use, however, I had a big problem. When I made outbound calls, people could barely hear me.

Is your reception good?

The signal was good and my reception was excellent, so that wasn’t the problem. Despite the good reception, I had to speak loudly and almost shout. As I spoke, I had to keep my mouth up against the built-in microphone before the person I was speaking with could hear anything.

There is no setting to turn up microphone

Naturally, I searched my smartphone’s settings to increase the microphone input volume. I was surprised to find nothing to adjust the built-in microphone controls.

Finally, after half-an-hour of searching for a way to turn up my built-in microphone, I found a solution. It was a weird way to solve the problem, I thought, but it worked.

Here’s what I did to increase my Samsung Galaxy microphone volume and make my outbound calls sound crystal-clear.

Once you see the 3 Phone apps listed, tap on the first one.

You’ll see this warning:

All of this application’s data will be deleted permanently. This includes all files, settings, accounts, databases, etc.

Once you read and understand the warning, tap DELETE.

After you delete the Clear Data settings and files, the Clear Cache might also be deleted automatically. If not, tap the Clear Cache button and follow the prompts.

Clear Data does not delete individual app data

As you can imagine, I was hesitant to Clear Data after I received that warning prompt. However, none of the data from my banking app, my online brokerage app, and my Walmart Pay app was deleted.

I was relieved to find I did not have to re-enter any of my usernames and passwords for those helpful apps. Since I use those apps at least once a week, I stay always stay logged in on my smartphone. You probably do the same thing.

In fact, the Clear Data did not delete any data that I used all the time.

8. Repeat process for each Phone app

After you cleared the data and cleared the cache in the first Phone app, repeat the process with the other two Phone apps.

Make a call

Seconds after I cleared the data and cache, I made a call. The receiving person could hear me well, and my voice sounded clear and resonate. To this android smartphone novice, it was like a miracle.

No need to reboot

I was surprised that I didn’t have to reboot my smartphone. Somehow, clearing the data and cache made my microphone work the way it should.

Clearing the phone data and cache worked

For this android novice, the process made no sense, but it worked. My near-new Samsung Galaxy J7 Crown worked, and I was able to make phone calls without a problem since then.

Clear data and cache each month

To avoid problems with my built-in microphone in the future, I think I’ll clear my phone data and cache each month. It’s how to turn up the microphone in the Samsung Galaxy J7 Crown, and it’s quick and easy, too.

The Samsung Galaxy J7 Crown is my favorite smartphone so far!
