Apple phone vibrates loudly and buzzes

If the vibration sound of an Apple phone is very loud and there is a buzzing sound, it may be that the vibration screws of the phone are loose or the vibration function hardware is damaged. The noise of the phone is the sound of coils or electric whistles. The high-performance processor of the phone or any electronic components may make this sound.

If your phone makes a "buzzing" sound, it is generally the sound of internal electrical current emitted by the speaker. If the situation is serious, it is recommended to go to a mobile phone repair shop for repair.

If your iPhone makes unusual noises when it vibrates, it may be because there is strong electromagnetic interference in the surrounding area, causing the iPhone to make a "buzzing" sound after being interfered by the electromagnetic waves.

The vibration diaphragm is the most core component of the mobile phone speaker. Once the vibration diaphragm is damaged, the amplitude and direction of the vibration will be wrong, which may easily cause noise in the speaker.

The iPhone has a card inserted but shows no card

There are several possible reasons why an iPhone has no SIM card: incorrect SIM card installation, oxidized SIM card, problems with the SIM card slot, such as internal rust, poor contact, etc. It may also be that the size of the SIM card is not cut properly, and iPhones use the smallest NanoSIM card.

Please make sure to use a standard SIM card. Do not use a non-standard SIM card or cut the card yourself. Cutting the card yourself may cause the SIM card to fail to recognize or damage the phone. It is recommended to go to the business hall to replace the original standard SIM card.

Check if the surface of the SIM card is dirty. You can use alcohol to clean the chip surface. If the SIM card is used for a long time, the metal surface is easily oxidized, which may cause the card to be unrecognized.

You can try turning the airplane mode on and off, or restarting the phone. If the problem persists after multiple attempts, it is recommended that you go to an after-sales service center for repair.

Apple phone gets hot after just a few uses

If your iPhone gets hot after just a few uses, it may be because some software is running in the background of the phone. When the phone is in use, it will generate power consumption, which will cause the phone temperature to rise. It is recommended to close unnecessary background running programs and turn off WLAN, Bluetooth, GPS, etc. when the phone is not in use.

When running high-energy-consuming apps on Apple phones to make calls, play large-scale mobile games, play videos, transfer large amounts of data, etc., the CPU runs at a high load for a long time, which can easily cause the phone to overheat.

When a mobile phone is charging, the temperature will usually rise. If you continue to use the phone at this time, the temperature will rise faster, so try not to use the phone while it is charging.

After downloading certain third-party apps, if you feel that your device is hotter and the battery standby time is shorter than before, it is recommended to uninstall the app from your device.
