It can be a little difficult to diagnose a touch screen mobile phone not working, especially if you don't know a lot about touch screen phones. If the screen is dead, it won't work! On the other hand, if there is a smudge on the screen, then the phone is most likely not working at all. Either way, you have to get it fixed or get a new one and this can cause a huge headache when you are trying to find out how to fix a phone that won't start.
The first thing you will want to do is make sure the screen is actually the problem. It can be an old screen or some smudges that were created by your finger. If the phone doesn't work because of the screen not being clean, then you are going to need to clean the screen. You can take the phone apart and clean the screen with something like rubbing alcohol. Be careful not to spray the liquid too close to the glass on the display though.
Next, remove any hardware on the phone. The antenna may be attached to the back of the device and is causing interference. If you can unplug this connection and use another device for touch operation, then this will clear up the issue. Note that some phones will still need software updates or repairs to work properly. Check the manufacturer's website for support information.
If the phone just isn't working at all, then the best thing to do is call your phone company. This way you can speak with a person who actually makes touch screen mobile phones. They can tell you if there is a hardware failure or if there is something wrong with the software on the phone. You will also find that they can offer you a free software update or a free device exchange. This can save you money over the long run!
One of the most common hardware problems involving touch screens happens when the screen is scratched. This is usually easy to fix. First you should try a glass cleaner or something small and clear to rub the screen. If the scratch remains, use a microfiber cloth or an alcohol wipe to get rid of the scratch.
Another common problem for a touch screen phone is that it thinks it is touching a non-existing touch sensitive area. For example, if you are typing on the phone and you move your finger to touch the home button, the phone thinks that it is touching the keyboard. To fix this, just tap the home button several times in succession and the phone should recognize that you are not trying to touch the screen. This will probably result in a re-orientation of the phone and the problem should be fixed.
In some cases, a touch screen mobile phone will lock up. To diagnose what is wrong you should look at any indication on the screen. If there is no indication of a problem, then the problem is probably with the communication system or some other hardware.
No matter what the problem may be, you should always try and fix it as soon as possible. The problem may not be hardware related and you may be able to fix the problem yourself. But if it involves a battery or the communication system, then you should have it looked at by someone who can fix it.
Another common problem is the screen freezing up. The phone may seem to work for a few seconds but then it locks up. You may need to restart the phone or let the phone go into safe mode. If this problem persists after you restart the phone, then you may have a serious problem and it is recommended that you do not touch the phone. It is much better to let the phone stop working than to touch it and possibly cause permanent damage.
Some phones will freeze up simply because they are not designed for cold hands. A person who has never touched a touch screen before will find this hard to get used to. The phone may not respond to your touch but it will most likely lock up. This is a problem that needs to be repaired as soon as possible. The lock up could mean that the user will not be able to input any data into the phone.
Touch screen mobile phones are a great invention but like any other product the problems too can sometimes be more than we expect. If you have a problem with your mobile phone, you should try to find the root of the problem before you call the manufacturer. If the problem persists, you may have to send it back to the manufacturer. This is a process that is not very difficult and one that will be handled by some good customer service technicians.
