It is not surprising that our phones can make noise that is not appropriate for normal use, also in the case of Xiaomi phones. The best thing in these cases is to be able to identify them and find a solution. In the case of these Chinese mobiles, you are going to verify that it is not something serious, and those strange noises can be solved.
Surely you have been wondering for a long time why your Xiaomi mobile makes that strange and random noise that does not make any sense. And it is true that most of the time this is the case, but there are others in which there may be an explanation, not a solution, since that is much more complex.
A hardware or software sound?
Logically when we talk about strange sounds and noises, there is no specific pattern to interpret them and therefore give an explanation. We must always take into account the moment in which the sound is produced in order to find a pattern to that noise. If it is always repeated making the same option, it is normal that it can have a more logical explanation.
We must also differentiate software sounds from hardware sounds . The first we will perceive as another notification sound, but the second could have a more metallic sound, or rattle, since we would surely be talking about the sound of a broken or loose internal component after a fall. Logically, if the latter is your main suspicion, you will have to go to the technical service.
Watch out for wireless connections
The existence of a random sound that has despaired of many over the years has been proven among many Xiaomi users, and it has an explanation. It’s all about the NFC connectivity and the proximity of chips to the phone. These are normally found in transport cards, bank cards, even the electronic DNI has one of these chips.
And if we carry one of these cards or documents stuck to the phone, and the data transfer via NFC is active, it is normal that when a device with this connectivity is detected that sound or notification is emitted . Therefore, if we carry them very close together in the portfolio and they oscillate, logically that noise will be produced. So there are two solutions, change the location of those cards so that no contact is made with the mobile, or temporarily disable NFC connectivity .
A ghost notification problem
This is usually another cause of these strange and unidentified sounds. We are talking about applications that in the background are emitting some type of notification that is not displayed on the screen, even in the notification bar, but that is emitted with a sound. Apps such as Social Drive have been found that emit notifications exclusively with a sound, and without showing anything on the screen.
If this is not the case, touch uninstall uninstall the latest apps, to check if the sound disappears. These notifications also usually refer to available updates, so check on your mobile that everything is updated as it should. And we are not only talking about app updates, but also Xiaomi’s system updates. In the accessibility options we must also check if there is any sound activated that can warn people with some type of disability about events on the phone.
