To gently clean the outer surfaces of your iPhone, you can use a wipe with 70% isopropyl alcohol, a wipe with 75% ethyl alcohol or Clorox disinfecting wipes. it is necessary not to spray products on the device (it is better to gently spray a lint-free cloth first and then pass it over the product); It is important not to use aggressive products such as bleach, prevent moisture from penetrating the slots and obviously not submerge the iPhone in cleaning products.
If you talk on the phone with different people who complain that your voice is heard poorly, there may be a possible problem with the iPhone microphones (there is more than one integrated device). If any foreign object comes into contact with the microphones, such as dirt, sand, makeup, ink, soap, detergents, acids, acidic foods or body creams, it is recommended to turn off the device and continue cleaning.
If the iPhone is stored in a case, remove it. Unplug the phone from the power source, locate the phone’s microphone (here we explain where the microphones are located on different iPhone models), and proceed with cleaning.
The different points where the microphones are placed can be cleaned with a microfiber cloth or a fine brush (avoid objects with abrasive surfaces: they may damage them). Never use metallic objects (such as paper clips), water or any other type of liquid and use compressed air (it may sound like a good idea but this often pushes dirt in). Very carefully you can use a toothpick (to push the debris out) or a suction system (always with great care and caution).
You can use a magnifying glass to check for dirt, as mentioned, a toothpick. Do not insert the latter tightly all the way, but limit yourself to small, delicate movements, to escape from the wreckage. A blower (such as those used to clean camera sensors) or a pneumatic dust remover can be used at the end of the cleaning to remove small traces.
Even if the microphone is not working well, the problem may be with the software. Remove any screen protectors, cases, or cases, wipe any dirt in the iPhone’s slots and try opening an app to record voice or video memos and test the operation of the microphones.
If the microphone is not working in a particular app, open Settings > Privacy > Microphone and make sure the app is enabled.
If you’ve followed all of the steps above, but the microphone doesn’t seem to work, contact Apple Technical Support.
