[INFO] NFC Service and Market

Learn from my Fail.
I was cleaning out some bloat yesterday by freezing a bunch of stuff I didn't need or want. After a reboot, I noticed that NFC Service was still running, even though it was frozen. I came to the obvious conclusion that it would be best to just uninstall it, nothing near me uses NFC anyways...
This was a mistake.
My Market started acting flaky... I could run it, and browse apps, and I could even update apps and install things I pushed through the web market, but as soon as I tried to view details about an app, Market would force close on me.
I tried all the obvious things like wiping Market data and cache, to no avail. Started poking through logCat and noticed that something was trying to talk to NFC Service around when I try to view an app. I restored NFC Service from titanium backup, rebooted, and the market works as expected again.
TL;DR: Do not uninstall NFC Service, otherwise your Market will force close when you try to view an app's details.
Hope this helps someone!

Good question, I have no idea... just reporting my findings. Perhaps someone more knowledgeable can shed some light?

I did the exact same thing for the exact same reason, but I only had issues when I used Google Play Store, when I did uninstall updates it worked fine. Unfortunately, it would always update itself, so I ended up flashing a custom ROM. Wonder why you can't freeze it or force close it?? Why is NFC always running?

problem disabling system update notifications on oneplus 8 pro

Hi. Thought I could get a little help with something. I got my 1+8pro and I rooted it with Magisk only. It was a little tedious but my root check app says it is rooted. I had trouble with my bank apps. One was so stingy that I had to redo the root using a different app name instead of Magisk. Finally got that working. Then I started getting notifications for a system update. Well, in order to update I had to wait until that version was posted on 1+ website so I could download it and patch it in. I finally did that and eventually got everything back up and running with the update. It was tedious and the phone is finally working again, just like I want it to.
About another week later it began nagging me again to do yet another update and I did not want to go through all that all over again. I went into the settings for that system app to disable the notifications but the switch was greyed out, locked in the on position. I live by important notifications and having that up in my notification area constantly is distracting. So I contacted support and asked how to disable the system updates or the notification. They told me to do what I already tried and I had to send them a screenshot showing that it was greyed out. Then they were trying to talk me into resetting my phone which is scary considering it took me many weeks to set everything all up.
So I said "uncle" and ended up going through the update baloney all over again and getting it rooted like before. Tedious. I checked after doing so and the notification setting switch was still greyed out. So, now it started nagging me to update again only this time wants me to go to OS11 which I am certainly not even ready to try as it is still in its infancy and not interested in taking a chance that something stops working properly on the phone.
I have a root uninstaller app on the phone that disables apps, but it is so old that it is no longer supported and apparently doesn't work with this newer Android version like it did on my old phone. It just brought the app over when I transferred everything from the old phone to this new one. It has app disabling features that apparently do not work for this version of Android. So I cannot use it to disable the System Update app. Now, I can probably install the Pro version of Titanium Backup which has an app freeze feature but not sure if it will work after paying for it. So before I do such a thing I wanted to see if there are any other options to maybe get this switch un-greyed so I can block these notifications. I know also that I can clear the cache and data for the app and it stops for a few days, but then I have to keep doing that once or twice a week and that is just a pitb to keep doing. Besides, 1+ said that it shouldn't be greyed out.
Anybody got any ideas for me to try without jeopardizing having to lose it all and start over? If I knew what I was getting into with Magisk, I would have installed TWRP first so I could have backup images to roll back to. But that is an afterthought now. I don't think Titanium Backup can create an actual flash image of the phone like TWRP. Maybe I should start over and just do it right with TWRP, then Magisk in the first place. But I want to leave that as a last resort.
Ideas, thoughts?
Thanks if you can.

Mallicious Motorola Software Update automatically updating despite disabled settings

I did the adb debloat method successfully (with some errors I mentioned in that thread), but when I connect to the wifi it quickly updated without my permission, despite my attempt to find all update related settings and disable them, I only found out in my notifications that "Last step to update is to restart" from Motorola Software Update, when I check its "info" disable is greyed out, SOB!
This is really pissing me off and making me want to yeet this heavy ass spyware piece of **** surveillance device out the window, I don't want to restart my device now, how do I prevent the device from updating now after restart? Motorola trying to copy Windows 10?

In Motorola Update you have disabled AutoReboot, and as you see your device is NOT AutoRebooted...
Also you can disable in DeveloperOptions/AutomaticSystemUpdates...

I wish your portrayal was the reality, I did disable automatic update in developer settings, even before it did the update. Ofcourse that didnt stop it, hence why the use of the word "malicious" in the subject line.

I've had updates disabled in dev options too. It seemed to work but this was on the z4 from last year.
What happened after the update? Everything you disabled was re-enabled.?
Could you use root and app manager from f-or sunny similar on f-droid to disable the offending app?
Just wondering.
Without unlocking and rooting I do not expect to have control over anything on my device. Even then some apps can be a pain to disable or remove.

Sorry for the delay, it is some sort of Motorolla security update, it already automatically downloaded one without asking for permission, now I get a prompt to download a new one (wtf so you force one but then ask later?), when I swipe up from the bottom to see all the tabs open and delete the update prompt, it will just pop up again later, I can send a photo if you want...

Boot into stock recovery and clear cache. That's the only way I've ever been able to "cancel" an update that's already been downloaded.
However, I don't know if this will still work on newer phones. No promises.
Either clear cache or factory reset the entire phone. FDR would certainly blow it away.

Unselecting Automatic Updates in Dev Options has never worked on any phone I've owned.

Root ASAP, install Titanium Backup (or similar) and disable all Update apps -- the only way I've ever been assured of blocking unwanted OTAs.

Disable Updates?

Sorry for potentially asking a dumb question, but im at my wits end here.
Is there any way to completely disable OTA updates, with the stock ROM on the Pixel 4a?
Asking because i have turned automatic updates off in settings and it STILL checks and STILL force updates the phone after a week or so. This is extremely frustrating as i have very specific versions of certain apps installed, eg Google Keyboard, Vanced YouTube, Pre stories Twitter etc. They are all configured exactly how i want and when it updates it installs the latest versions and consequently ****s all the settings up at the same time. This means i have to spend a few hours uninstallling, reinstalling and re configuring the whole ****ing phone again.
So yeah, is there a way? I am rooted with magisk if thats of any benefit. Ill do anything, even if it fundamentally breaks google play store/services and requires ghetto apps like LP/Autostarts etc. I just want my device how I want, not what some trillion dollar company wants.
My last device was a Mi A2 Lite and it behaved itself perfectly before i destroyed the screen. Starting to regret this upgrade.

When you say "I have turned automatic updates off", did you do this in the play store app? If so, good.
But, you can also try these extra steps:
1) Turn on "Developer Mode" on your phone (do search for how to do this). Then go into developer options and turn off "Automatic System Updates".
2) Then do the changes I did in this post:
How do I stop update notices?
I'm rooted with Android 10 on my pixel4a. I don't want to upgrade to 11 just yet, but I keep getting the annoying update notices. Is there an app or module I can freeze with titanium to turn off the notices?
forum.xda-developers.com
Since doing these, I have not seen an "Upgrade to Android 11" (I'm on A10) message and I have not noticed any apps being forced updated.

yeah google play updates are disabled. which is interesting because after the phone updates, it re enables them, as well as a bunch of other permissions in settings!
and yeah ive disabled auto system updates in developer options, which is what im pissed about because it still updated the phone without my permission whilst i was asleep last night.
ill try and force freeze those components you listed, see if that kills it.
i might have a poke around the autostarts app later and see if i can do something there, thats if it even works with android 11.
the last time i had to do this was on my nexus 7 running kitkat lol

Question Is there a way to disable automatic system updates?

It seems Samsung is forcing updates no matter what's turned off in the phone. I have them turned off under developer options, but it's still downloading and installing updates - and with every "system" or "security" updates, it installs other garbage. Apparently I needed "Samsung Visit In". And it keeps giving its stupid apps permissions to cameras/microphone/modify system settings/etc. Really frustrating.
Is there a way to disable that completely? Does anyone know of a package name that I could uninstall via ADB that stops it from downloading patches automatically - hopefully without bricking the whole thing? Or do I have to root it and install something else completely?
I've tried searching here, googling everywhere, and it seems there's nothing...Not sure if Verizon took a few options off - as some of the menus screenshots look different for some people online.
Thanks!

Thanks! That was one I haven't ran across yet. 2 of those (systemupdate and updatecenter) are on the do not remove lists on google docs; so had I initially left them alone, but I removed them now, I guess what's the harm...
I could not find wssyncmldm; but while I was in ADB the update popped up again on the phone, clicked on 'learn more' and realized it's verizon that's pushing these updates, not Samsung... So then I went and disabled a lot of verizon/vzw stuff I found, hopefully I got it...
No wonder the old Nokias ran for weeks on a charge, they didn't have all this garbage in the background... lol.
Thanks for the help!

Update, after disabling those the system updates still showed up. I downloaded a package inspector, found it to be com.samsung.sdm. Googled that, people mentioned com.samsung.sdm and com.samsung.sdm.sdmviewer to be the culprits. With the update screen up I disabled com.samsung.sdm and it went away. Disabled sdmviewer too just to be safe, but so far looking good for now.
Their garbage reinstalled samsung pay and all of the other bloatware that I had removed when I got the phone... so frustrating!
