Google Translate is great. We download 2 or 3 languages that cover where we are and then remove the ones that won't be in use for a while as they eat up a good bit of
storage on the device.
The camera translate is incredible. Snap a
photo of a sign, menu, whatever as long as it can read the text, it rewrites it in
English on the picture.
It's all but impossible not to be tracked and live a normal life. Either put on the tin-foil hat and check out of society or adjust the settings as best you can and move on with life.
