Black Shark's mobile phone has a white screen after updating, so it can't use WLAN and hotspot at the same time.

Please try the following methods to solve the problem:

When the traffic used through the hotspot reaches the set traffic limit, the phone will automatically disconnect * * *. Please turn off traffic restrictions and see if the network will be disconnected again. Open phone settings > WLAN & gt mobile network > portable WLAN hotspot >: single traffic limit (below EMUI8.0), or set >；; Wireless and Network > Mobile Network * * * Enjoy > Portable WLAN Hotspot >; Single flow limit (EMUI8.0 and above), modified to unlimited.

If the phone connected to the hotspot is disconnected when the screen is locked, click phone settings > WLAN & gt configuration (below EMUI8.0), or settings >; Wireless and network > WLAN & gt configuration (EMUI8.0 and above) will keep WLAN connection dormant and set it to always before checking whether the problem still exists.

Please check whether the network is disconnected due to electromagnetic interference sources or signals away from hot spots. I suggest you move your position and see if this phenomenon will happen again.

If the phone turns off the screen, the hotspot will be automatically disconnected. Please confirm the creation of APN, change APN protocol and APN roaming protocol to IPv4, and other configuration items are consistent with the default APN. 1. Take a telecom card as an example: If a dual card is inserted, please select the APN of the default mobile data card. The way to view the default mobile data card is as follows: EMUI8.x: Settings-Wireless and Network-Dual Card Management EMUI5.x: Settings-Dual Card Management. 2. Select a new APN in the upper right corner and make the following changes: (1), name: please enter ctnet 1 (any name, as long as it is different from the default APN name) (2), APN: please enter ctnet (consistent with the default APN) (3), and both APN protocol and APN roaming protocol choose IP. 3. Select the newly created APN CTNET 1 in the APN interface. 4. Turn on the data network switch and portable hotspot again, and the WiFi disconnection problem can be fixed. If you use other operators' cards, you can modify them according to the above method.

Please try to turn off the personal hotspot and then turn it on again to see if other devices will be disconnected frequently after being connected. Or after the two devices are restarted, try whether this function can be used normally.

If the above methods can't solve your problem, please try to change your mobile phone to connect to this hotspot. If the network is still disconnected frequently after connection, there may be something wrong with the hotspot function. Please back up the information in advance and go to the nearby Huawei customer service center for maintenance.
