1 Cracked or broken screens

One of the most visible and frustrating hardware issues in mobile devices is a cracked or broken screen. This can happen due to accidental drops, impacts, or pressure. A cracked screen can make it hard to see or touch the display, and can also expose the internal components to dust, moisture, or debris. Depending on the severity of the damage, you may need to replace the entire screen or just the glass layer. Some mobile devices have special tools or kits that can help you fix the screen yourself, but others may require professional service.

The best way to prevent a broken screen is to invest in a good screen protector and case. I personally prefer the ottorbox defender as a case along with a zagg screen protector. You definitely get what you pay for.

2 Battery issues

Another common hardware problem in mobile devices is related to the battery. Over time, the battery capacity and performance can degrade due to aging, overcharging, overheating, or physical damage. This can result in shorter battery life, unexpected shutdowns, slow charging, or swelling. To diagnose battery issues, you can use apps or settings that show the battery health, usage, and temperature. To fix battery issues, you can try calibrating the battery, optimizing the power settings, or replacing the battery if it is removable. If the battery is swollen or leaking, you should dispose of it safely and seek professional help.

Battery life is king. For many the worth of the phone comes from how long it can last. Unfortunately, batteries don't last forever. The constant charge and discharge cycle leads to the battery losing capacity over time. Even if someone practiced charging their phone before it gets to 0 percent, that only delays the inevitable. As someone who had their galaxy s7 for 6 years, I know. Before I got a new phone, I had to carry around a power brick constantly as the battery life was around 3 hours.

3 Charging port issues

A related hardware issue in mobile devices is the charging port. The charging port is where you connect the power cable or adapter to charge the battery or transfer data. However, the charging port can become loose, dirty, or damaged due to wear and tear, dust, moisture, or bending. This can cause the device to not charge properly, not connect to the computer, or not recognize the cable. To diagnose charging port issues, you can try using a different cable, adapter, or device. To fix charging port issues, you can try cleaning the port with a toothpick, cotton swab, or compressed air, or replacing the port if it is broken.

In most of the cases, is that the charging port is loose due to forced attempts to position the charger or letting it bend while connected. Cleaning with toothpick would not really be recommended, for someone with no technical knowledge as it can also lift or break the pins/stripes inside the charging port. Whenever possible, seek professional help and advice.

4 Camera issues

Many mobile devices have one or more cameras that allow you to take photos, videos, or make video calls. However, the cameras can also experience hardware issues that can affect their quality or functionality. Some of the common camera issues in mobile devices are blurry or distorted images, black screen, autofocus failure, or flash malfunction. To diagnose camera issues, you can try using different camera apps, modes, or settings. To fix camera issues, you can try cleaning the lens, restarting the device, updating the software, or resetting the camera settings. If the camera is physically damaged or faulty, you may need to replace it.

5 Speaker or microphone issues

Another hardware component that is important for mobile devices is the speaker or microphone. The speaker or microphone allows you to hear or speak during calls, play or record audio, or use voice commands. However, the speaker or microphone can also have hardware issues that can affect their sound quality or functionality. Some of the common speaker or microphone issues in mobile devices are low volume, distorted sound, no sound, or feedback. To diagnose speaker or microphone issues, you can try using different apps, headphones, or external speakers. To fix speaker or microphone issues, you can try adjusting the volume, cleaning the speaker or microphone holes, restarting the device, updating the software, or resetting the sound settings. If the speaker or microphone is physically damaged or faulty, you may need to replace it.

6 Hardware security and tampering

A final hardware issue that is not very common but very serious for mobile devices is hardware security and tampering. This is when someone tries to access or modify the hardware components of your device without your permission or knowledge. This can compromise your data, privacy, or device functionality. Some of the signs of hardware security and tampering are unusual marks, scratches, or openings on the device, missing screws or parts, altered serial numbers or labels, or abnormal behavior or performance. To prevent hardware security and tampering, you should always keep your device with you, use a lock screen or encryption, and avoid unauthorized or suspicious service providers. To detect hardware security and tampering, you can use apps or tools that scan the hardware configuration, firmware, or memory. To recover from hardware security and tampering, you can wipe the device, restore the factory settings, or replace the compromised components.
