What to do when you can't create an account because of email format, an already-registered mailbox, network errors, or a lost email address.

If you can't register an account in the Smart Night Light app, work through the steps below in order.

Detailed Steps

Email format problems. If registration fails because of the email format, confirm the format and enter it again before registering. Pay attention to special symbols and spaces.
The mailbox is already registered. Log in directly, or tap Forgot Password on the login screen, enter your mailbox, and tap Reset Password. Then open your mailbox to read the new password and log in. You can also reset the password through a mobile phone number: on the phone login screen, tap Forgot Password to open the password retrieval page, fill in the mobile phone number, tap Get Verification Code, enter the new password in the password field, and tap Reset Password. It logs in automatically once successful.

Mobile phone number registration is temporarily offline due to an issue with the operator.
A "request failure" prompt during registration. Do the following:
- Check whether the mobile network (Wi-Fi or cellular data) is turned on.
- Check whether the app's network access permission is allowed. Go to Phone Settings → Application Management → Smart Night Light → Data Usage or Application Permission Management.
- Once the network is confirmed normal, try again a few times or try later.
- If it still fails after several attempts, tap Guest mode on the login screen to use the product's features normally.
Network problems. You can enter Guest mode to try the app. Guest mode only supports local features and cannot use network features. If the network recovers while you are in guest mode and you want to register, first go to the Me page, tap Log out at the bottom, then log in or register from the main screen.
Forgot or lost your email address. Register again, or send an email to [email protected] for manual processing.
