change device name ?

Ok i finally find it..
Go to settings->bluetooth tap the settings button and there is rename phone options!

Only affects your device's "Bluetooth" name. Other Bluetooth devices will see the name you give here; Wi-Fi devices will not be affected however. They will continue to see the funky name the original poster complained about.
 
My HTC One 4g from Vodafone, running 4.4.2 with Sense 5.5 and SmartLauncher2 has many names: About phone name, Bluetooth, WiFi- direct, WiFi- hostname/router/ssid, WiFi client; all are editable except for the WiFi client name, which appears to require root or superuser access.
 
After phone reboot it restores name to the old one, the same with:
> su
> getprop net.hostname
> setprop net.hostname <new_hostname>
method.
 
You can add this as new to line build.prop file in /system folder and it will be saved for ever (root required)
net.hostname = UrNewHostname
 
You don't need to root the device as it's a very simple stock feature. Just go to ABOUT PHONE and you'll see DEVICE NAME there.
 
Finally you gave me the clue..

Thanks yar..

This one worked for my Xperia with Jelly bean..

Renaming in the blue-tooth settings will change only your device name for blue-tooth communication.

This will change your name in a network.
 
I didn't work for me.
As I connect to my desktop with an USB cable, it is still identified as a mobile device named "XT1572".
I could change its name from desktop but I am afraid of doing so under Windows 10 and messing things up a little further somewhere else.
Can't we do that from the phone iself? Device Manager app downloaded from Play Store returns some error while loging in.
If it is useful: Moto X Style, Android 6.0 system version 24.221.4 , kernel 3.10.84, build MPHS24.49-18-4
:confused:
 
Changing the name through Windows (if it even lets you) would only mask the real name whenever you connect it to that computer. It won't change anything on the phone.

There is no way to change the name without rooting. Any app that can change the hostname will require root because it is a trivially simple command which requires root access.
 
Maybe this is too old to comment on, but I change my device name in the Google Device Manager online. Go to Google Play, in the left Nav select Devices, then in the left hamburger menu choose Android Device Manager. From there you should be able to edit the name of your device. As far as that affecting the actual host name on network, I'm not sure if it's the same thing.

Cheers,

It's way easier than it seems. Download the app "Device manager" by Google. Log in with the account you used for your phone. When logged in, press on the three dots top left. There, press on "Change device name" and enter a new name :D hope this helps you!
 
Settings - About device - Device name - just tap and rename.
In case of Galaxy S6.
I hope it will work for u as well.
 
On my Moto G4, I just plugged it in to my Windows 10 machine using a USB cable, opened filed explorer, right-click on device, hit "Rename" and named it what I wanted.
 
Not sure if anyone is still looking for an answer to this, but it was one of the first hits from google when I was trying to figure this out...

I ended up changing my device's name on my local network with a static DHCP lease. Just have DHCP tell the phone what it's name is and it works.

I'd guess that you can't change the name on the phone since it has to be somewhat globally unique. Otherwise you'd get 10 guys naming their phone mr. black, and dns would get screwed up..
 
I tried the solutions here, and some (like the DNS Hostname Changer app, or using a terminal emulator to "setprop net.hostname") work temporarily, but the only solution that works PERMANENTLY (after a reboot) is to edit your buildprop file, which requires being rooted.

There are many ways to edit your buildprop file if you're rooted, but I used the free app, BuildProp Editor (by JR Rummy Apps) to edit the buildprop file. To do this:
1) Launch the BuildProp Editor app.
2) Grant it SuperUser access (through your superuser app, which will probably pop up).
2) Click on the pencil icon to edit the buildprop file.
3) Scroll to the bottom of the buildprop file and tap on an empty line.
4) Type: net.hostname=YourDesiredName (Your Desired Name must use alphanumeric characters, dashes and underscores only. Note that there is no space on either side of the equal sign.)
Alphanumerics, dashes, and underscores are OK.)
5) Click on the "save" icon at the top. (It looks like a floppy disk. Who remembers those?)
6) Select "Save & Exit".
7) Reboot the phone.
