Many of us facing keyboard lag issues when typing there are several reasons why this happens,but I have solution for this problem it works almost all android devices 100% and fix this issue 

On typing words in keyboard the words in keyboard gets struck at displayed after 2-3 seconds of typing,it makes our mobile hang or delay response and feel discomfort of using when showing this keypad lag problem

You can fix your Android Keyboard Lag issue simply by hard resetting your device by pressing and holding both power button and volume up button for 10 seconds it makes your mobile hard reboot and your keyboard lag now solved,if you were using third party keyboard from play store then clear it's cache and data to fix keyboard lag permanently.


Don't use your Android device while in charging mode cause when charging the power flows all over mobile circuit that makes touch irregular response which is the cause of keyboard lag on typing


Some people install different type of keyboards from play store and from website applications,because they want to look their keyboard attractive with different styles and coulurs with attractive wallpaper

But they mostly contain virus that steal your data so they works on background and its cause for the lag of third party Keyboard while using,other than the keyboard that comes from manufacture is not recommended for any android to use


Even the keyboards placed on play store were dangerous you can see some keyboard applications in Android play store for some days and they suddenly disappeared from play store,the reason behind what is the play store detects that keyboard has malicious virus and works a keylogger for developer so they remove those apps from play store,I don't know why play store give permission without checking it 100% at all but after some days they remove from play store
