How to run both WiFi and hotspot at the same time on an Android device

It is possible to connect to a Wi-Fi network and share that Wi-Fi connection via a mobile hotspot at the same time, to make your phone act like a Wi-Fi repeater or extender, but only on a very narrow range of Android devices – usually high-end smartphones, except for several Huawei/Honor phones.

As far as I know, only the following devices can share their Wi-Fi connection:

Samsung (“Wi-Fi sharing”):

• Samsung Galaxy S7, S7 edge and S7 Active
• Samsung Galaxy Note7 and Note FE
• Samsung Galaxy S8, S8+ and S8 Active
• Samsung Galaxy Note8
• Samsung Galaxy S9 and S9+
• Samsung Galaxy Note9

LG (“Share via Wi-Fi connection” / “Wi-Fi sharing”):

• LG G5
• LG V20
• LG G6
• LG V30 and V30S ThinQ
• LG G7 ThinQ
• LG V40 ThinQ

Honor (“Wi-Fi Bridge”):

• Honor 6X
• Honor 7X
• Honor 8 Lite
• Honor 9 Lite and 9i
• Honor 10
• Honor View 10

Huawei (“Wi-Fi Bridge”):

• Huawei P10 Lite
• Huawei Mate 10, Mate 10 Lite and Mate 10 Pro
• Huawei P Smart
• Huawei Nova 2i
• Huawei P20 Pro
• Huawei Mate 20 Pro

Essential:

• Essential Phone

Google:

• Pixel 3 and 3 XL

Xiaomi:

• Pocophone F1
• Redmi Note 5
• Mi 6X
• Possibly other models

Smartphones brands that do not support this feature for the time being:

• Apple
• HTC
• OnePlus

For the smartphones that do not natively support this feature, it is possible to use third-party applications that provide this service, but they are usually less user-friendly, and not free, or require that you root you device. Here is a guide: Como usar seu Android como um repetidor Wi-Fi.

Nota: Se você notar um erro ou um dispositivo faltando na lista, não hesite em indicá-lo; eu irei atualizar a lista.
