Please, help me with this problem. My phone is in demo mode, here is app "G6 4G", this app turns on every 30s and it is video and photos about phone-advertisement. To end it, the app want password. How can I end it? Please help. Thank you very much.

Welcome to Android Central! Did you buy this brand new from Huawei, or did you get it used from some other seller? Demo Mode usually means the phone was a floor model with a special demo ROM. If this is just a demo app, then presumably the dealer set the password, so you'll need to find it out from them.
