Install Russian input method on android I don't have Russian input method in the list of methods available. Tried third party apps like 'change locale' bu they are changing interface of the OS and not giving me to type in Russian. 

Android version: 4.1.2, Device: Samsung Galaxy S2 LTE
You need to look at 3rd-party keyboard replacement apps, not locale changing apps.

Many well known keyboards like Swype and SwiftKey offer Russian layouts as either an in-app downloads, or separate add-on packages (like AnySoftKeyboard's language packs for example.)

Keep in mind that after the initial installation new Keyboard apps are not enabled. Go to Settings -&gt; Language &amp; input, scroll down to "Keyboards &amp; input methods" section, tap on the checkbox of the newly installed app, and tap OK to accept the scary warning. You should now be able to switch to your new keyboard. This is for Android 4.x; on other OS versions the menus might be slightly different.
