Why Is the Top Left of my iPhone Screen Blurry?

Other Common Issues With iPhone Screen

Screen Not Sensitive Enough

If you have placed a screen guard on your iPhone screen, this could be one of the reasons for the poor sensitivity. Try the following methods to fix this problem:

Remove the screen protector and case – The touchscreen may cease functioning if you apply a thick screen protector that hinders the screen from sensing your fingers’ electrical capacitance.

If your touchscreen isn’t functioning, or works intermittently, remove any object around or on the screen, including the screen protector or phone case. If the screen works seamlessly after removing these accessories, it’s time to get a thinner screen protector or a different case.

Wipe the screen to remove any water or debris – This method is the simplest and works almost instantly depending on whether you have exposed your iPhone to rain or dirt.

Unplug accessories from the phone’s lightning port – Connecting any accessories to the lightning port can interfere with the screen’s sensitivity. If anything is connected to the port, including a power bank or charger, unplug it.

If the action solves the issue, chances are, the accessory is incompatible with the iPhone.

If all of the above-mentioned options fail, you can restart your device.

If the sensitivity is not restored after restarting the device, then contact Apple Support or visit the nearest Apple Store to get your screen fixed.

iPhone White Screen of Death


An iPhone screen may appear white for an extended period due to a jailbreak, failed upgrade, or a hardware issue. To resolve this issue, restart the device. If that doesn’t work, factory reset it.

Sometimes, even factory resetting won’t fix the problem; if that is the case, boot the iPhone in the Device Firmware Upgrade (DFU) mode.

Remember that factory resetting or booting your iPhone in DFU mode will clear all of your phone data and settings. That said, remember to back up your data on iCloud often.

iPhone Screen Not Working in Cold Weather

During winter or in colder regions, your iPhone screen may stop responding. You can fix this issue in several ways:

Don’t Take Your Phone Out When It’s Too Cold

If you must carry your phone outside, then stash it in your pocket and keep it closest to your body. That said, don’t leave your iPhone alone for extended durations in frigid areas, such as a parked car.

An iPhone is not designed to withstand freezing temperatures below 32 degrees F. That’s why the phone may shut down or deplete its charge if you use it under extremely low temperatures.

Turn It Off

If you do not wish to leave your iPhone behind, turn it off. Hold down the device’s side button and one of its volume buttons for a couple of seconds.

The power-off slider will appear. Now, drag the slider and wait for thirty seconds for the iPhone to turn off completely.

Use a Thermal Protection Case

Specific cases are built to regulate your iPhone’s temperature under extreme conditions. For example, cases like Neoprene, Optimal, etc. are designed to ensure the iPhone operates well under low temperatures.
