I am expiriencing some problem, i am absolutly not able to type anything on my nexus 5 phone. Can you help me in this regard, also is it because of system change in the settings?
Welcome to Android Central! More details would be helpful. Which keyboard app are you using, Google Keyboard? Is the keyboard not coming up at all? Is it coming up, but not registering your keystrokes? Have you tried other keyboards like SwiftKey?
