My iPhone 5c touch screen is not responding to my finger

Question

I've had my iPhone 5c for a couple months now. I have not dropped my phone but the touch screen has suddenly stopped working and doesn't read my finger swipes or touches. Sometimes it will start working again for a brief time but then stops working again.

Hello there, Aim5353.
The following Knowledge Base article offers up some great recommendations for troubleshooting touchscreen response on your iOS device:

Resolution
If your device is experiencing any of the symptoms listed above, try the following steps:
Restart your device
Hold the On/Off button until "slide to power off" appears. Slide to power off your device. When it is off, press the On/Off button to turn it back on.
If you can't restart your device, reset it by pressing and holding the Sleep/Wake button and the Home button at the same time for a least ten seconds, until the Apple logo appears.
Clean the screen with a soft, slightly damp, lint-free cloth.
Avoid using the device while wearing gloves, with wet hands, or immediately after applying hand lotion.
If you have a protective case, or if you are using a plastic sheet or film on the display, try removing them and testing the device without it.
If the steps above don't resolve your issue, please schedule a service appointment with an Apple Retail Store for evaluation. If an Apple Retail store is not an option, contact Apple to find out your best service option or see the Service FAQ for your product.
Additional Information
Tip: To isolate an issue related to a portion of the Multi-Touch display, follow these steps:
Open the Maps application and double-tap each corner, then the center, to verify that it zooms in to each section.
If a specific area is affected in another application, note the location and try to verify touch functionality for that location in the Maps application.
On iPhone and iPod touch, you can also use Calculator:
Open the calculator app to test all but the top row of the screen. Press each button on the calculator and verify activity.
To test the area at the top of the screen, rotate the device to change to the scientific calculator and press the buttons in the left or right two rows.
When speaking with a Mac Genius or Service Provider, you can use this information to assist with evaluation of your issue.
