How to fix an iPhone if it is having common problems is easy if you know what the problem is. For example, if the iPhone screen is frozen, the quickest and easiest way to fix that is to turn your iPhone off and then off again. Or, you can reset your iPhone by holding the home and sleep/wake buttons down at the same time until you see the Apple logo appear. If worse comes to worse and your screen is still frozen, connect to iTunes and restore the iOS. You will lose data that way, but if you have backups on iTunes or iCloud you can restore whatever was lost.

If your iPhone won’t turn on you should first check to make sure it’s fully charged. Sometimes the iPhone won’t charge even though you have it on the dock and connected to a wall outlet or your computer, so check your cable and try a different method of charging. If it still won’t charge in order to be able to turn your iPhone on, you may need a new battery.

If the trouble with your iPhone is that you can’t connect to Wi-Fi, make sure Wi-Fi is enabled by checking the settings. If it is enabled and just not connecting, restart your iPhone to see if it will connect. Sometimes you won’t get a connection if your iPhone is trying to connect to a specific network. If this is the case go to Settings, Touch Network Name and then Forget. Then, restart your iPhone and try again.

If you need to fix the camera on your iPhone because it isn’t working, check Settings, General, Restrictions and double check to see that “Allow Camera” is set to on and that “Disable Restrictions” is also selected. If it is and the camera still isn’t working, restart your iPhone and see if it will work. You made need to restore your iPhone from iTunes and if that doesn’t work, you will need to contact your local Apple Store to see if there is a hardware problem.

Another common problem with iPhone 4S or 5 is that Siri will stop working and you can fix that issue by cleaning your microphone on the bottom of your iPhone. If that doesn’t work, go to Settings, General, Siri and switch Siri off, wait for a minute and then turn Siri back on. If that doesn’t prompt Siri to start working again, go to Settings, General, Reset and reset the network settings.
