I started recently to look up for a way to permanently disable my wifi, bluetooth, NFS, Network and GPS. Unfortunately I didnt find a proper method to do that. There was the option to physically break the hardwares, but I didnt want to risk that, if I get something wrong there I wouldnt have a 2nd chance. Except of that, there was only some ways to disable the wifi but it was easy to re-enable it again.

Anyways I figured out, that I need to root my device in order to remove hardware files, but the problem is I dont know WHICH files would be okay to remove.

I'm using a samsung galaxy s8 with Android 9 Pie

Till now I rooted my device twice and deleted hardware files,

the first time I deleted wifi hardware files from the system/etc/permissions folder. That lead to brick my phone.

The second time I deleted hardware files of bluetooth and nfc from:







surprisingly it worked, I totally disabled bluetooth and nfc.

Then I wanted to proceed to remove gps (I figured out S8 aint using gps but gnss) so I removed the gnss files and folders. But this time, it bricked my phone, so I had to reinstall the samsung firmware again and now I rooted my device again.

Before I start trying again, I would like to ask you, if any of you have some knowledge about this and if there is any no-go files, which I should never remove or smth.

I dont really just want to try out over and over, it is taking much time to do all this... I hope somebody can help me out.

Additionally, do any of you know how the network hardware is called? basically the hardware which lets you call people or just the hardware which connects to a network provider.

The reason why I want to do this shouldnt be important right? but if you want to know why:

I want to keep my privacy. I want to be able to connect to the internet only via ethernet cable and also I want to use my device more as a map to plan routes, camera, calc etc.

ALOT of other people want to do this too, but nobody (after searching for over 20 hours) had the right solution. Every way I found, it was possible to reenable it easily.

Thank you for taking your time and reading my issue! I hope you can help!!

I will give an update about this anyways!

    You may be better off asking on the android stack exchange site.

    But overall, there is a lot of cross referencing and includes of libraries that happen throughout the filesystem and you can't go deleting files like that. Wouldn't you be better off buying a dumb tablet with only wifi instead of a phone with multiple radios?

  • @cde that's what I thought too, but you dont find a tablet without bluetooh or gps(maybe), additionally, my S8 is already old, so I didnt want to spend more money for a new device

    I'm certain most tablets do not have GPS. You can always just disconnect the antenna on your phone though. Or ground them.

I'm using a samsung galaxy s8 with Android 9 Pie

Model: SM-G950F


I found a way to disable the following hardware:

(disclaimer: there is probably tons of methods to permanently disable hardware, but this is how it worked for me)

Ofc you need to root you device, I used TWRP as boot loader.


you could loose your data forever!! and dont do the same mistake I did, not backing up the contacts.

Contacts are NOT in the internal storage, therefore you need to do a back up while rooted!!!

Tip: every file you edit or delete, make a backup of the original one and name it differently. If your android bricked, then you can use TWRP and delete the modified file and rename the backup again to the original name. This would help you to prevent wasting much time.


Delete the following file:

/system/vendor/lib64/hw/[email protected]


Delete the following file:

/system/vendor/lib64/[email protected]


Delete the following file:


Some files I just edited them, these are permissions file, if you delete them completely, android wont work anymore.

You need to delete everything between <permissions></permissions>

You can edit the files using text editor

GPS: Edit the following file:


NFC: Edit the following file:


Telephony: I tried to dial emergency numbers, which should be actually possible with or without a sim card, but it didnt work.

Edit the following file:


And that's it, now just restart your android and it should work with no problems.

I would recommend to download everything you want to have on your phone, before you get rid of wifi.


Most google applications like google map wont work, after you get rid of the gnss/gps. Google doesnt like it, if you turn off your location lol

The network data (LTE, 4G ...etc) is not tested and I am not sure if it is even disabled, I have the feeling that Telephony is not the same. I dont use a sim card anyways, so yeah. But if I found out a solution for that too, I will post it here for sure!

have fun!!
