    Problems of Chinese smartphones

    Will be useful

    On devices made in China, the Recovery menu is often displayed on Chinese. This creates additional difficulties for users, which, however, are completely surmountable.

The first two hieroglyphic characters are very similar to the combination capital letters: Latin “I” with elongated horizontal upper and lower elements and Russian “G”. Therefore, if the text on the screen begins with “ІГ”, we are most likely in the right place.

    The second evidence that this is the Recovery menu, albeit in Chinese, is the presence of Latin characters “MMC” in the seventh line. These three letters complete the text of the line.
