Either look on the keyboard for a symbol of earth near space bar ....thus will change language ....or go into menu settings and look for language.if it is a language you can't read use another device which you can use google translate and convert English into Chinese ...japenese to see what it looks like in another language.then you will be able to select right option if menu is unreadable.

the language setting is in the preference set up screen. But you probably will need someone to to talk you through how to get it.

To change your language go to:

Settings > Languages & input > Language > Select the one you want.

If the tablet is in another language and you cannot read any of the labels, please follow the instructions below:

Get into settings. The icon looks like three bars with small ovals intersecting them. From here, you should see a list of icons on the left side of the screen, followed by text (which may be incomprehensible). Look for the Languages & input icon which looks like an A in a white box. From the following menu, choose the very top option. It doesn't matter if you can understand the text or not - it says "language." The following menu should show a list of languages, each as it's described in that country. For instance, English is written as "English," but German is "Deutsch." In other words, it should be very easy to find the language you understand - just look for it from the list of options and it should be immediately legible. Once you tap your language option, the system language should change and you should be able to understand the rest of the system menus.
