February 14, 2018—KB4077675 Update for Windows 10 Mobile (OS Build 15254.248)

Improvements and fixes

This update includes quality improvements. No new operating system features are being introduced in this update. 

• This build includes all the improvements from KB4074592.

• Addresses issue where the touch screen would remain unresponsive. In most cases, using the Power button to turn the screen off and on restores responsiveness. Occasionally, at startup, the touch screen would remain unresponsive, and the only recovery mechanism was to restart the phone.

• Addresses an issue that delays the on-screen keyboard from reappearing when an external keyboard or scanner is used with device. With this customization, an OEM can define the delay value. For more information, see On-screen keyboard delay.

If you installed earlier updates, only the new fixes contained in this package will be downloaded and installed on your device.
