Touchscreen issues can be caused by either a software bug or bad hardware. In most circumstances, an app issue would cause the iPhone touchscreen to stop working. The issue can be narrowed down to a single stock or third-party software, as well as the iOS device itself. Often, the issue manifests as a simple malfunction that occurs at random, but it can also be more sophisticated at times. Complex touchscreen issues are typically those that were caused by a defective firmware update and could not be resolved using any of the available remedies. This is what happened to several iPhone 6s owners after they installed the iOS 11 firmware update, which resulted in an unresponsive touchscreen.
Solution
efficient solution to sophisticated software issues impacting iOS devices, including your iPhone 6s, is a recovery mode restoration.
Here's how to restore your iPhone 6s from recovery mode:
- Connect your iPhone to a computer using a USB cable.
- On your PC, launch iTunes.
- Press and hold the Power and Home keys on your iPhone while it is connected until the Recovery Mode screen appears. When the Apple logo displays, do not release the buttons; instead, wait for the recovery mode screen.
- When iTunes asks if you want to restore or update, choose Update to have iTunes reinstall iOS without wiping your data.
Wait until iTunes has finished downloading your iPhone's software. Your device will exit recovery mode if the operation takes more than 15 minutes. If this happens, you'll have to go through the procedures again to get your iPhone 6s into recovery mode.
