Phone info setup as a device administrator

Hello,
I have had my phone for a while now, but today was the first time since I got the phone that I looked at the device administrators area (settings / security / device administrators) and I noticed that there was an item called "Phone Info" that was activated by default and after reading about what it is supposed to do, I decided to deactivate it, but I was unable to do so. My questions therfore are:
1.) what is the purpose of this item?
2.) why can I not deactivate it?
3.) is it normal for it to be activated by default?
4.) if is not needed than how do I get rid of it?
In case it helps, my phone is rooted and I am still running the stock 4.1.2 ROM that came with the phone.
A few days ago I tried out the "All In One" 4.3 Stock ROM from Thunder Stick, but it was not working for me to well so I restored my nandroid backup of my original stock ROM so I am not sure If the other ROM has anything to do with it or not or if the setting has always been like that, but as I said before, I just noticed it today and would like to know what it is and how to deactivate it if I can.
Thanks for any and all replies,
Mtcell

Can you post a screenshot?

Here is another one that shows the permissions dialog and where I should be able to deactivate it, but pressing the deactivate button has no effect.

That is weird. I am checking my s3 now but this is all it shows on my optimus G. Maybe it is a Samsung thing?

Edit: here is what my s3 shows under those settings, but remember, my s3 isn't activated. Maybe it is just the activation stuff?

"I think a ducks opinion of me is heavily influenced by whether I have bread or not."

Thanks for the reply. After doing some research I have discovered that it is part of some corporate security thing that sprint has on some of the newer s3's (see the attached screenshot) Anyway, I have frozen the app since there is no way to disable it. That will work for now until I change my stock ROM in a few weeks.
If anyone else has this app setup as a device administrator and wants to disable it than you can use the pro version of titanium backup or the free version of sd maid to freeze the app like I have done. Note, your phone must be rooted to use these apps.

Data connection problems

I am using a Virgin Mobile Samsung Galaxy S3 SPH- L710. I am not sure exactly what type of information that any of you would need in order to help me but I will just say everything I did. I rooted my phone using some safe way that was pretty easy and it worked and everything but it would not work for a certain root app I wanted to download. So I then reverted the root and tried to root using some siyah kernal so that I could use a certain app. Long story short I ended up changing the firmware(if thats even the right term) from Virgin Mobile 4.3 to Sprint 4.1 which is now not letting me use any data. I am unable to text, browse the web, or use anything that involves using any time of signal. I don't know how to fix it now I have tried some things but nothing fixes it. I don't know what further information that would be required in order to get help with this so PLEASE feel free to ask me and I will promptly respond in order to fix this problem THANK YOU.
TLDR: Switched from Virgin Mobile firmware to Sprint by accident now I have no data connection. My goal was to root my phone and use the siyah kernal on Virgin Mobile firmware.

Someone tried to help me on another forum but still my data connection still isnt working.

Have you tried flashing the MD4 modem?

I found one on this link http://forum.xda-developers.com/showthread.php?t=2247844 but I think the link is working. If you could post a link or where to download it just so that I make sure that I get the correct thing. Wait but I just want to make sure that I download the right thing since nothing has gone well for me so far.

Go to Android Forums under (Virgin Mobile) Galaxy S3 - All Things Root and look for a thread called [MOD] Sprint to Virgin Mobile LTE /MMS fix. Download the zip from that thread and flash it. It'll fix your settings to get you back on Virgin's network.

[Q] issue with verizon lg g3 custom roms

Hi xda ! I'm hoping someone can help me ! I have a Verizon LG g3 I was messing with custom rooms and I flashed cm11 I believe and decided I didn't like,it ( I know weird) but I flashed back the the Rom I liked prior and realized my phone didn't recognize the SIM anymore. So I tried different rooms and have come to the conclusion it won't read Sims anymore. I want to uproot and go to complete stock, I have tried the different ways online and I can't find how to change port settings. If someone could assist me in either flashing back or any ideas on why it won't recognize Sims because I want to fix it that would be great! Please email me at [email protected] as I don't get on here to check often thanks

Have you tried turning off your phone > pulling your battery out > pull out your SD card and SIM > Clean them up nicely, blow a few times in the SIM/SD card hole on your phone > re-insert > Boot up your phone.
Also, this should be in the Q&A section. You've been a member on here for over a year but only have two posts, so I guess you don't frequent the forums very often. Please use the exclamation mark to report your thread so the mods can move the thread.

It also doesn't see the firmware version and bandwidth

Never heard of any such issue. Try flashing kdz.

After installing software using LGUP, the phone keeps resetting itself

It works!!! For those in need: I turned on LGUP and selected the "ChipErase" option

But now you have wiped your IMEI and serial number. In all my guides I warn people not to use that option.

Right. I haven't checked it out. There is no IMEI or SN now. Can it be restored somehow?

Such things are not allowed to be discussed here on XDA, as far as I have heard. You'll have to find another site to see if there's a way to do that.
In the future, don't go running around without knowing what you're doing, because you will break things, as you have just now done. Most people should never use Chip Erase, as detailed on many threads here.

Success with adding IMEI. Now there is still SN

Yeah this sounds a lot worse than playing with Windows Regedit.
Cloned hdd copies are a beautiful thing...

Dialer Codes Not Working

Hello everyone,
I have a Samsung Galaxy S20 Ultra (SM-G988U) from Verizon Wireless. I am not from the US, I got the phone from a guy who bought in the US.
I am currently in Romania using Vodafone SIM card (Idk if this is relevant but thought I should give as much info as possible).
The thing is, no dialer code works, *#06# for IMEI code, *#0*#, *#*#88#*#* and all the other ones. It either says invalid code or something like that or "UNKNOWN APPLICATION".
I am running original unrooted firmware Android 11 One UI 3.0 (G988USQU1CTL4).
Is there anything I can do to solve this? And is there a way to get rid of the Verizon stuff without rooting? (like changing CSC or something I don't know I'm not all that knowledgeable regarding this stuff, I just read the stuff posted on the forums)

Not sure if it will work. But try downloading the Google Phone Dialer and see if they work in that app.

I get the same errors with the Google Phone app too.

Codes won't work if the BL is unlocked or rooted.
Happened on my old S9

At least read the whole post before replying , I am running completely original unrooted software. Didn't touch a thing on it.
Didn't mean to make it sound passive aggressive, just frustrated with the whole thing.

perhaps the previous owner rooted the phone before.. try to enter download mode to see if it was rooted before.
