Periodically, you may notice that your cellphone screen is blurry, or otherwise distorted. The screen may be blurred for several reasons. For example, you may have dropped the device in a pool of water or dropped it on the ground. If your phone has a hardware issue which is not resolvable by resetting your phone, you will need to take the device for physical repairs. The phone likely has a hardware issue if, after resetting the device, the screen remains blurry. Before taking the device in for repair, several steps are available to get your phone back to normal.
Inspect the device for water/liquid damage. Remove the battery compartment to locate the sticker that alerts you that the device got wet. If the sticker changed from white to another color, the device suffered water damage. If the screen is damaged because of water damage, it is not fixable by resetting the device, as it is a physical hardware issue, and not a software issue. In this event, take your phone into your provider's retail location to have them fix the device. Be prepared to pay any repair or replacement fees, particularly if your phone is out of warranty. The mobile provider will tell you whether your phone is out of warranty.
Dry your cellphone if it was damaged by water. Remove the battery and excess water. Press gently on the screen to get rid of excess water, if necessary. Let the cell phone and battery dry in an area where the device won't get wet. For example, place the device on a window seal, while the window is closed. The device could suffer further damage if it rains. Do not let the device dry near a heat source, such as an oven or heater. Let the phone dry up for to three days and power it on again.
Perform a "soft reset" on your device. The screen may clear up with a simple reset. Performing a "soft reset" merely restarts the phone, without destroying data your have saved on the device. Power off the device by holding the "Power" button for a few seconds. Remove the battery compartment and battery from the device. Replace the battery and battery cover after several seconds. Power on the device.
Perform a "hard reset" to restore your phone to factory condition. The hard reset erases all data from your device. Use this option if you have ruled out water damage to the screen and the soft reset did not solve the problem. The instructions for performing a "hard reset" differ for every device.
