No doubt that Gmail is one of the most used Email service of the world, It provides many services which attracts users.
But Gmail has a very annoying feature, at least for me, Suppose you got a mail and if you reply that mail or just forward it, Then Gmail will automatically saves that Email address to your contacts under Others.
If you also wanna disable this annoying feature then Just login to your Gmail Account, Then visit Settings and under General Tab, scroll down and then you will find a option saying Create contacts for auto-complete, Just select I’ll add contacts myself.
That’s It, Now just save it and you are done.
