My J3 2017 doesn't show up keyboard after restarting, how to solve it?

[Android Central Question]

I have activated power saving mode and I got busy with my computer for about 2 hours, then I needed to call some one, but the keyboard doesn't show up for entering password, then I restarted the phone, and I hoped it work, but it doesn't. I have tried the "Power button + volume key + Home key" but it show a warning in Chinese language and with clicking volume up key, it shows a downloading page, and if try this method with volume down, and home button, the phone restarting, how can I get the keyboard to reopen my phone?

Welcome to Android Central! Where did you get the phone from? The fact that the system menu shows up in Chinese makes me wonder if it's a fake/knockoff phone (unless it's a J3 that was meant for the Chinese or Taiwanese market).

You can try connecting a basic USB keyboard via OTG cable to get by the password entry.
