If your iPhone is not acting the way that it should, your initial thought may be to take it to a professional to be repaired. However, the problem may actually be simpler to repair than you think. Try these DIY tips for repairing some common iPhone problems.
Loose Lightning Port
Have you noticed that the lightning connector no longer sticks in your phone like it once did, causing your phone to not charge or not connect to your computer? The problem may not be due to your port being broken or a bad cable, but due to dust that is stuck inside the port. Take a toothpick and dig out the link that has been pushed to the bottom of the lightning port over the past year or two. If you do find a large chunk of compressed dust, put the lightning cable back in and see if that fixes the problem. The cable should now fit snugly in the port and not fall out with ease.
Unresponsive Home Button
Another problem you may have is a home button that is not responding or not reading your fingerprint that well. This problem can be fixed using a Q-tip and a small amount of rubbing alcohol. Dip the Q-tip in the rubbing alcohol and work it around the entire home button. This can help remove any sticky substances that are preventing the home button from pressing inward and being unresponsive. The rubbing alcohol can also help remove dirt on the home button that is preventing it from reading your fingerprint.
Bad Call Audio
Do you feel like the quality of phone calls over the earpiece has diminished, causing you to resort to using the speakerphone so that you can hear the person at the other end of the phone call? This problem could be from dust trapped in the earpiece. You can actually remove that dust by rubbing the earpiece with a toothbrush. The bristles will be gentle enough to not damage the speaker like a toothpick will, and they will help remove anything that is blocking the sound. Give the earpiece a try afterwards and see if it makes a difference.
If you have a problem that cannot be fixed with these DIY tips, consider bringing your phone to a cell phone repair company. They'll can handle much more complicated problems that involve opening up the phone, such as battery and screen replacement.
