Pin unlock without showing numbers When you type your pin into the Android lock screen, it does the usual mobile password field thing where it actually shows the last character you've entered. 

Is there any way to disable this on vanilla Android 4.4? As in show only dots.
Since I just upgrade to 5.0/Lollipop, I can't confirm for sure if this setting is present in KitKat/4.4, but in 5.0, you can hide the last digit in the PIN unlock screen by turning off the Security setting labeled Make passwords visible, as seen here:



This is found under the general Settings app under the Security section.  Note, however, that this also affects password fields elsewhere in Android, such as in the Chrome browser.
