No one wants to have to worry about iphone 4 repair after theyve bought their very first gadget. But regardless of how well you maintain it, you can never be too confident that it will last long. Accidents happen and sometimes, there are factory defects that you only discover after the warranty expires. So, you have to be prepared for the likelihood that you might have to do some damage control yourself. It sure beats spending cash on iphone 4s repair services you can do on your own.

Here are some of the most common iPhone problems and their remedies:

Cracked iPhone rear panel, screen or broken battery
First, turn off your phone, then, remove the Phillips/Pentalobe screws next to the dock connector. Secure the replacement parts and get them in place. Then, screw back the back panel, and then test out the device.

Scratches on the back panel

Dab a small amount of toothpaste on the area affected and then spread it. Leave it on for a few minutes, and then wipe it off. Regular application will improve the state of your gadgets back panel. You can also use water mixed with baby powder or baking powder. Just be careful not to wet your phone.

Prevent iPhone water damage

Dont switch the device on after its been drenched. Dont charge it, either. Just wipe it immediately after retrieving it and let the air take care of the moisture. You can also dry it off using your hair blower, in its lowest setting. If you were able to save it just in time, the iPhone will just switch on by itself after a while. However, if it was immersed in water for too long, chances are you might have to buy a new one. Its easy to get parts as replacement, but once the internal hardware is damaged, not even an iphone 4 repair genius would be able to fix the problem.

iPhone signal problems

You can use duct tape or rubber bands to support the connection between the two antennas of your gadget (found on the bottom left side). You can also get cases to prevent skin contact, since studies have shown it to significantly decrease signal strength. But, call drops may not always be the devices fault. Although Apple has gotten a lot of bad press for the poor signal reception of their products, networks can also be blamed for this. Check your provider too, before you do unnecessary interventions.

Unresponsiveness/Crashes

When your iPhone freezes, turns off by itself or does not follow commands, just do a hard reset on your device. Hold down the sleep and home buttons for 20 seconds, then release. The Apple logo will appear and all will be restored.

Yellow stains on the screen

Just leave it alone. They will disappear after one or two days of use. The stains are caused by incomplete evaporation of the bonding agent used to put together the layers of glass in iPhones.

If your gadget is experiencing camera malfunctions, search limitations and switched functions keys, you might want to visit the Apple store or a reliable repairman (if your device is not under warranty anymore) to get iphone 4s repair assistance.
