works - sort of It appears to work by setting the Locale value in software. True, that will allow apps to access the translated string file for that target language. But it requires setting it to developer mode and connecting to a PC with adb.exe installed - fine for a developer like me but not for a normal user - and it does not change the dropdown under Settings...Language and Input, so switching between languages cannot be done from Settings, as it should be.

Droid razr maxx HD on android 4.4.2 Developers mode is closed on my phone and i can't do anything to install Russian language pack. It should be really very-very good if your developers will find a way to make it work on 4.4.2 without root! You saved us for a long time ago! Save us again!

Ameen Jones Its a very good app worthy of 5 stars, however i've switched from Galaxy S4a 4.4.1 -- 3.#.# to S5a 4.4.2 -- 3.4.0.. i've taken care of "obKNOXious" via root so pm grants aren't needed like before. Native languages like dutch and korean shows the phone fully in the language in the settings, morelocale 2 build isn't fully supported with most kernels now so some things are and aren't in japanese on my phone.. Only way to get around this is a custom rom or they patch this.

Works okay.. The Português pack only changes some in app language and a few applications otherwise the entire rest of the system is in english and unchanged. It works with the adb permissions granted on Samsung note 3 but again the Português pack needs updates.

Cool app that switCH a us phone into a Chinese phone After root your phone using kingo root，this app enables one click switch from English to Chinese. After the language changes, the Google maps and other related apps also showed Chinese instructions.

Changes somewhat Android 4.1.2 on LG Optimus F7 and it doesn't really change anything more than in-app language and some of the app names. Otherwise all system names are unchanged, at least that's the case for the german pack.
