How to turn on a call on a Xiaomi smartphone: 5 ways to solve the problem

Are you missing important calls because Xiaomi isn't sounding? This is a problem that affects users of all kinds of models, from the budget Redmi Note to the flagship Xiaomi 14. It can be caused by software failures, incorrect settings or hardware malfunctions. In 80% of cases, the call sound can be restored without going to the service center, just follow the verified instructions.

In this article, we will look at all the possible ways to turn on a call, from basic volume checks to hidden developer settings. We will focus on the typical mistakes users make when diagnosing a problem. For example, many people forget to check the Do Not Disturb mode or the sound profile, which wastes time on unnecessary manipulations. And some people do not even suspect that it may be... a case with a magnetic lock!

If your Xiaomi vibrates but doesn't ring — or doesn't respond at all — you'll find a solution here. MIUI 14/15 (For convenience, instructions are divided by difficulty levels, from simple to advanced. Let's start with the most obvious, but often overlooked, things that are obvious.

1. Checking basic volume settings

Before you dig deeper, make sure that the problem is not the basics. 35% of the time, a call to Xiaomi doesn't work because of randomly altered volume settings or activated silent mode.

• 🔊 Physical volume buttons. Press the top button on the side of your smartphone, a slider will appear on the screen. Make sure the volume level of the bell is not at zero. If the slider is gray, then silent mode is on.
• 📱 Sound profile. Swipe down from the top edge of the screen to open the notification bar. Find the Sound icon and tap it. Select Sound or Vibration mode. + sound».
• 🔕 Do Not Disturb. In the same notification panel, check if the crescent icon is active. If so, tap it to turn it off.

On some Xiaomi models, for example, POCO X5 Redmi 12, the default volume buttons only regulate media sound:

1. Press the volume button up/down.
2. In the window that appears, tap on three points (⋮) top-right.
3. Select "Call Loudness" and move the slider.

⚠️ Note: If the sound is completely lost after the volume change (including music and notifications), the audio driver may have malfunctioned, in which case only a reboot or resetting of the settings will help (for this, see section 4).

2. Diagnostics of hardware problems

If the basic settings are fine, but the call is still down, it's time to check the hardware. Let's start with the simplest one, the speaker. It's probably contaminated or damaged. Here's how to check:

• 🎵 Speaker test. Call your number from another phone. If you hear the call melody (albeit quietly), the problem is settings. If not, the speaker is faulty.
• 🔊 Multimedia check. Play any song or video. If there's sound, the speaker is working, and the problem is the call settings.
• 🧲 Remove the case (if you have one) and repeat the test. Some magnetic lock cases block the proximity sensor, which causes the smartphone to "think" that you are talking, and turn off the sound.

If the speaker doesn’t make any sounds (including music), try the following:

1. Put your headphones on and see if they have sound, and if so, the problem is the dynamics of your smartphone.
2. Blow the speaker (carefully!) into the hole, there may be dust in the speaker hole. Use a soft brush or compressed air to clean.
3. Check if the device has got moisture, and if Xiaomi has fallen into water or been in a wet environment, the contacts may have oxidized.

⚠️ Note: If your Xiaomi has fallen or been mechanically stressed, do not try to disassemble it yourself, this may cause additional damage.

1. Call melody. Go to Settings. → Sound and vibration → Make sure you don't pick "Silence" or "No Sound».
2. Vibration on the bell. In the same menu, check if the "Ring Vibration" option is on. If yes, but no vibration, the vibrator may be defective.
3. Contact notifications: Open a contact that doesn't have a call and check if it has a customized "No Sound" tune.
