如何更改基于android 7.0的设备名称 gigaset gs170智能手机< / a>所以它出现有意义/可读名称，例如在路由器的连接WiFi设备列表中？
How can I change the device name of an unrooted Android 7.0-based Gigaset GS170 smartphone so it appears with a meaningful/readable name e.g. in a router's list of connected wifi devices?
Various resources (e.g. this or this) suggest I should find a line saying Device Name in the About Phone section of the phone settings. However, I can see no such line there (images before and after scrolling down):
As the device is set to German, here are the translations of the items in their order of appearance:
Is there somewhere else I could look for that option, or is it something only supported by specific devices?
There are a few questions about this on this site (e.g. this and this), but those were posted several years ago, when early versions of Android with some "childhood diseases" (read: lack of basic features) were still the state of the art.
AFAIK it's possible that a phone manufacturer hide that option from UI on their products, and I guess your phone it's one of them. My phone OnePlus 5, however, does allow changing it from Settings app.
So, if root access is available, try this in a rooted terminal environment:
setprop net.hostname "Whatever You Like"
/system partition as R/W, head for
/system/build.prop. Find this line and if it exists, change it (this line may not be present on Android 5 or lower):
ro.display.series=Same As Above
Reboot is required. After that the new name should have effect. Before modifying
build.prop consider making a backup of it (and have a means of restore, e.g. via recovery-mode): if the file is "broken", your device won't boot up properly.
On my Android 7 phone (Zenfone 3) I was able to change the bluetooth name as follows:
