Personal Hotspot: Change Name, Password and Band auf Oppo
On Oppo phones running Coloros, the personal hotspot works right after you switch it on. Android generates a default network name and password automatically, so you can share your mobile data connection without any setup.
That default configuration is fine for a one-time connection, but it is not ideal for regular use. A generic hotspot name makes it hard to spot your network among several others nearby, and a factory password is easy to guess if you share it often.
You can change every relevant option from one screen. Open Settings ➔ Connection & sharing ➔ Personal hotspot ➔ Personal hotspot settings. There you set a custom network name, a new password, and other options such as visibility and frequency band, then confirm with Save.
The band setting matters if older laptops or budget devices struggle to connect. Switching from a 5 GHz-only hotspot to a dual-band or 2.4 GHz option usually fixes that.
Hidden networks improve privacy but require every device to enter the name manually before it can join, so only disable visibility if you actually need that extra step.
