[Q] Anyone know what ADCP does?

I notice there's always a system process called ADCP running, I think it stood for Amazon Device Control Program. Anyone investigated what it does and what happens if you disable it? I'm wondering if it's involved in any way with the OTA updates, and also what ramification disabling it has, like will the various Amazon programs not work right? I've not been adventurous enough to experiment with, in fact I've got my wifi off for now until it's clear whether the OTA update can be blocked by the methods discussed here.

essentially it connects the amazon apps to the kindle registration

I'm suspicious, I suspect it does more, and is the thing responsible for the OTA updates everyone is getting no matter what they do....

I really want to try and freeze it, but too afraid that it might actually be necessary...

Well I installed Droidwall and didn't give permissions to ADCP and so far my device is still registered and I can watch videos and use my books, can use the Amazon App Store (I gave it permissions, I don't think it's the program responsible). I've effectively disabled ADCP by not allowing it to connect to the internet, but it's still running in case it does, say, DRM services or something. All good and still on 6.2 (and I did do the other suggestions previously).

Glad it worked for someone else too. I am not sure which process is actually responsible for downloading and installing the update though.
EDIT: Oh, I didn't post about DroidWall in this forum. I figured out DroidWall last night and we posted on Gizmodo about it.

An important element I overlooked, even after adding apps to the whitelist, you have to go back to Menu and enable firewall. It's NOT enabled by default even if you change whitelist apps. Even though I had it not running firewall until 10 minutes ago, I hadn't received update. Maybe moving otacerts.zip stopped it....

I installed ADCP on CM7 when I was trying to find a way to get amazon video working. It brings up the page to register your kindle, but it never seemed to work right on CM7. There's a different apk for the OTA update, if I remember correctly.

You could put /system/etc/security/otacerts.zip back in and see if ADCP then lets your register your kindle.

Useful Prevention Tools For Amazon Updates, Non Root Users

WARNING: NEW UPDATE (14/13.3.2.3) ROLLING OUT, I ADVISE NOT USING THESE METHODS FOR NOW IN RISK OF ACCIDENTALLY UPDATING. STICK TO AIRPLANE MODE AND WIFI OFF FOR NOW. USE THESE METHODS AT YOUR OWN RISK. Thanks to Faznx92 for the update notice.
Alright guys, I believe I have found a decent way on how to prevent Amazon updates while using the device. Some may have done this but maybe haven't mentioned these methods because I have never found a thread on this. If you have other ways to block Amazon's updates, please don't hesitate to post! This is to help you and me, all ideas are welcome
1. Blocking WiFi
I found a neat app on the Google Play store that allows you to block inbound and outbound WiFi transmissions, (or you could just turn off the WiFi yourself, but hey, are you fast enough?). It is called "Net Blocker". Upon starting the application, select every Amazon application (including settings, which is the gear icon) and check the mobile and wifi boxes. You should see the wifi and mobile icons disappear next to the application names. One more important application to disable is your current LAUNCHER. This way the WiFi/Mobile Data is disabled when using the launcher. The WiFi/Mobile Data will be re-enabled if you go on an application that isn't blocked. EX: If you are using Silk Browser (with WiFi/Mobile Data enabled), and hit the home screen (with launcher WiFi/Mobile Data disabled), the WiFi/Mobile Data will disable on its own, since you blocked the launcher.
2. WiFi Timer
Amazon likes to be a butthole and likes to update while you sleep. This app is called "Wifi Timer", which is on Google Play, that allows you to set a schedule when you want your WiFi on or off (or you could just turn off your kindle and not use it). Just add a schedule, select all the days of the week, and where it says "stop wifi" set the time whatever time you go to sleep. It should disable the WiFi at that time if not already disabled by Net Blocker. (Just to be really safe, set a bunch of schedules during the night to disable WiFi) (Also I don't know much about what happens in the background during the update process, but if the application is still running in the background, I'm sure that the WiFi would turn off during the downloading process if your schedule turns the WiFi off. But Amazon probably closes all the running applications before starting the update process so that nothing interferes with it.
I must state that these methods are a tad bit risky (for now). A big flaw in these WiFi methods is the Kindle's feature on remembering the WiFi's password, EX: When the Kindle Update starts, it will search for your saved WiFi and automatically connect with the password it remembered. So if we can find a WiFi manager application that will purposely forget the WiFi's password so that you have to always put in the password every time you want to log in, then that will fix the flaw. Again, Amazon will probably prevent that type of application from running in danger of stopping the updates.
These applications work on the kindle. For those who want to directly download the applications from Google Play use Evozi's Apk Downloader (search for it on Google). When you get to the website copy and paste the Google Play address of the application and click download.
3. DIY Zip Dummy
There has been some debate on this method, I don't recommend this because I'm pretty sure that the kindle has it's own partition for system updates. Basically in this method you fill up you kindle's memory with a zip file full of memory to take up space "preventing" the kindle from installing anything else because of insufficient space. But I wouldn't do this, unless you do it for testing and you want to risk yourself into getting an update.

That was a huge error on my part, I meant to say droidwall, which is the application that requires root to block addresses and applications from wifi.

Block wifi completely when idle
I would just like to add that there are several "battery saver" apps in the kindle store that will immediately disable wifi when the devices screen is off. This way you don't have to worry about schedules at all. When the device is not in use, WIFI is off.

Despite the fact that I blocked all the Amazon stock apps- settings, kindle,etc. I can still download things. This is quite worrying, if I can download it, maybe the kindle can by itself? Maybe I am missing something, lets hope its something obvious.

Could it be silk browser? It is default when it comes to downloading files. Depends what application is downloading. I had no problems preventing downloads, whenever a download is launched by any application (that had the WiFi disabled) the WiFi shuts off, like the Amazon Appstore, and my browsers. Make sure to have the launcher shutdown also so nothing will connect to the internet while using the launcher.

I don't like seeing the same mistake happen twice. There are some good ideas here but there is only a hand full of ways to block the ota update and the most effective ones need root.​
1. Roms that removed the ota apps and functions. -root
2. Airplane mode or turning off wifi
3. Apps that block wifi or try to filter it (extremely risky)
4. Tools that disable ota. (My kfhdx utility is one example.) -root
Until we crack the thing I wouldn't joke around with firewall blocking or trying to do so (<-- the mistake I first made).
At least we have ways to block ota effectively. Requires a little patience.

Thanks for the notice, ill update the thread with that warning before attempting these.
Also as a precaution I would recommend going to the WiFi settings and go to your nearest connections and "forget" them, that way if out of nowhere an update starts (which will never probably happen) it won't have anything automatically to connect to.

"Android OS" consuming insane amount of data in background

I have a Samsung Galaxy S7 Edge, on ver 6.0.1; Build No:MMB29K.G935FXXU1APD1
Notice couple week ago, I have finished my monthly data quota of 3Gb, upon checking data usage close to 1/3 is consumed by "Android OS" in background.
Since then, I been on quest to find out what actually caused the drain on data. I have tried
1. Run in safe mode, "Android OS" in background continue
2. Factory reset, "Android OS" in background continur.
3. "Reset Network Setting", work for a couple a day, then "Android OS" in background came back again.
4. Off all Google Account Sync and Off background data, "Android OS" in background continue too.
Now I am really out of ideas... really disappointed with Android now.... planning to sell off my phone and switch to Iphone

Just as a comparison, between 7am to 1pm today, "Android OS" already consumed 37Mb; while my web brwsing in the same period only used up 95mb. And I have Facebook app disabled already.

at a 'wag' I'd speculate that you have one/all of the background reporting enabled (diagnostics, security reports, app scanning, et. al.).
you could also take a walk through the 'optimize battery usage' settings to restrict the various apps to limit their usage.
these things are discussed in the battery consumption thread(s) but they also affect data usage.

^^^ what he said
I had the same issue the very first week I got the device (800+ MB consumed by Android OS) - it automagically stopped once I greenified and Dozed the sh!t out of it.
Mind you, even at the beginning I had no sync and most of apps disabled for background data usage.
Sh!ty implementation if you ask me: it almost looks like a collusion between Google and the carriers to waste your data. Why on Earth would they otherwise have "Download boost" and "Smart network switch" which both suck up your precious little data (I speak as a Canadian screwed by the monopolies...).

"duh" - they can bill you for more data consumption, makes complete sense to me!
I had the thought that it'd be very nice (from a user' point of view) of everything not absolutely necessary was disabled by default and a nice 'wizard' walked you through enabling of ANYTHING which will use background data, location, or radio (essentially anything using power or money). Sort of the mirroring the "secure by default" ethic where everything would need to be individually opted-in. Alas, I feel this is contrary to the interests not only of the phone carriers (who want to bill more for data service), OEM (who want to regularly sell you a new device), and Google (who wants to leverage data of/about/by you to create $).
Or maybe I'm just a little cynical.

how you greenify Doze? dont think it is available on Sammy phone.

I started to monitor the "Android OS" usage every 5~10min... what I notice is, it starts drain data every time I go online, e.g. surf net, FB app, etc.
So for example, surf net at 10:00am... and close the browser... 5 min later I will notice the "Andoird OS" data consumption increased by another 2-3Mb.

2.9beta2...read the forum thread in the Greenify section.

Ok, seems to have found a solution. I boot into recovery and
1. wipe cache
2. wipe data
now it is running ok. "Android OS" no longer draining data in background.
Not quite sure why the previous two time factory reset via setting menu wont do the tricks though.

I have the same trouble! Android SO consumes a lot of data, I'm gonna try your solution I hope it works!!

AASAservice
Download the Package disabler in google play and disable the system app named AASAservice. You will be OK. I found this solution through a data manager app called DATAEYE. If you still worry about your data usage, you can try to use this app too.

Samsung is actually very open about it. They said that first and foremost, it is the carriers, that are their customers. Not the average Joe blow like us.

I think he's talking about BK package disabler Pro which is what I use too, great app.
However, cant remember now if this is possible in MM but in Android 7 Nougat you can restrict data usage for anything you like except apps that really need to use data like facebook and your browser etc, but you can still restrict them from using background data regardless, screenshots below, as far as I'm concerned, theres not really much on my phone that I want accessing my data without me knowing about it, I don't send picture messages etc, and I don't need weather and traffic updates every 10 secs etc.

Can anyone tell me what is this?

Google Play auto updates don't seem to work after package disabler...

I recently discovered the joys of package disabling, using this XDA article as a guide and it has been 99% amazing. My battery life went up significantly and the bixby button is disabled without having to use some third party app.
However, the 1% that isn't amazing is the fact that google play seems to no longer be able to automatically update my apps. I can go in and manually update them, and it still shows a big list of which apps are available to update, and auto update is still turned on... but I suspect something I disabled may be not allowing google play to actually run the updates. Any thoughts?
I was reading another thread about which things people have disabled, and someone mentioned the settings menu loads slower... another person knew right away that it was two services that you had to re-enable, so I figured maybe someone just kinda knew what to do without having to go through each service/package and guess...

I ran basically the same huge long list that guy exported in the thread about disabling Bixby / etc.. and I didn't experience this issue. You may have to play the 50/50 game until you isolate which service is responsible

Samsung Galaxy note 20 ultra Europe exynos sm-986b debloat/decrapify

Hi,
Samsung Galaxy note 20 ultra Europe exynos sm-986b debloat/decrapify (Switzerland/Swisscom).
I'm starting my journey to debloat that phone which is entirely unusable for me, due to the unwanted presence of hundred of junk apps.
After realizing that I was not using a data cable but only a charging cable (computer not having usbc, I had to use another cable than the official one). I manage to get my bearings a bit.
So the connection is sorted out (out of topic), now start the actual decrapifying:
1) I used/will use this program, to list all programs:
https://forum.xda-developers.com/an...easy-management-android-applications-t4147837
Note: I could have used adb directly but this seems easier, especially as we talk about hundred of lines.
Note 2: each time I installed "ACBridge" which appears to show nice icons for that program.
2) I have compiled a list of applications currently installed. I did not install anything manually myself yet, not even connected to Android Play:
442 apps by default.
https://gofile.io/d/xGHoff
Note: Are some of these apps only specific to my seller and my region? It's possible, since the phone clearly had some of the FYI operator branded options installed.
3) I'm going to factory reset now. Again, nothing was really installed, just official rom updates done. But I want to start from fresh.
4) After I will reinitiate the phone, I will redo the list of applications capture, and start trimming down.
5) After the factory reset, it seems I had a new screen (unless I skipped it by mistake last time) proposing me to install additional apps like spotify, linked in... I refused this time. Last time I had the apps installed maybe a mistake click, or something new thanks to newer firmware.
6) Use the program again, I now have 429 apps only instead of 442.
7) I tried the list mentioned a starting point, I will look into this user list, allegedely 109 apps removed from a S20 (which is a different phone, I know):
https://forum.xda-developers.com/t/tool-windows-adb-appcontrol-v1-4-5.4147837/post-83980273
First that only has 104 apps over 109.
Second, I found a few items I wanted to keep and a few I wanted to remove.
Customization Work required here...!
Caution: the list of 109 items contains what is described elsewere as dangerous:
com.samsung.android.authfw ; Not Recommended: Used for password autocompletion, can be removed if you don't use it. This app is sometimes called by the system and might cause battery drain if removed
com.serv.android.preloadinstaller : App that install other application, do not remove!
I will check each non-obvious items.
This list seems more pro:
Samsung full apps list
Feuille 1 LAST UPDATED 01/09/2022,Reinstall an app using pm install-existing [the app package],Enter in shell using adb -d shell before running the command,Enter in shell using adb -d shell before running the command,<a href="https://docs.samsungknox.com/CCMode/G988B_Q.pdf">https://docs.samsungk...
docs.google.com
I made a custom preset with the 85 items in the list of " Safe to uninstall ". Only 71/86 where showing, some I wanted to keep like Android Auto.
--> I seems to have to choice but start from a bigger list and go through it myself.
After checking each items of that 109 list, vs the spreadsheet and sometimes google, I actually ended up reducing the list, or keeping more items. My final list is currently 68 applications to remove.
I also removed additional things like Netflix.
FINAL LIST:
Samsung SM-N986B_[All]_presetJSDec2020.txt
In the process I learned that this list seems rather personal to do. Yet, some items are marked not to be removed due to battery drain, so the initial list of 109 seems risky. I would say some manual work is mandatory.
8) Moving on, time to uninstall. Done.
9) Time to configure the basics again (basically language, etc...). Done.
10) Time to migrate data from old phone to new phone, I used "Samsung smart switch" app, installed it on both phone, used wifi, and unselected unwanted things. Done after some 1-2 hours (not so much data but it was slow and I interrupted twice).
11) Now the phone looks ok, a few apps had to be manually reinstalled like MCDonald's crapp.
12) Time to recover authenticator, relogin to apps, etc...Some apps I can't do now like RSA token, needs to regenerate a token elsewhere. GoogleAuth was simple, I could easily export from old phone/import new phone..
13) Phone works for now. I see I missed to remove some stuffs like "My files" which was basically simply like file explorer but from Samsung. That was indicated as "not remove" but probably can be ( com.sec.android.app.myfiles ).
Edit: day +1 after the step 13. Phone works properly. No visible impact on battery drain (seems high, as usual and with little usage overnight, same as before any intervention from my side). Unable to continue anything for now, being ill. Everything seems to work, even without the stuffs I removed.
On that note, I got rid of youtube and yt music, and installed YoutubeVance.
I tested the basics (phone, camera...) looks ok.
Note: this is WIP and more sharing the journey, as well as learning. Usually I would unlock bootloader, root, and install a decent ROM from XDA; but not happening this time.

Glad that could help- The tool from Cyber Cat and the threads are useful. Yet I saw quite a few tools/options around.
The idea was to share the experience of using one, do some sort of decrapifying/debloating and comment.
For me even if I expected a bit that, I was a bit surprise that this operation needs a lot of customization.
Let's say it was easier to start from a fresh Android ROM and add some selected Google apps, rather than trimming down that Samsung junk (That something I usually do with custom roms, here I stayed with official Samsung ROM, so I did not have that possibility to start fresh).

I see Android 11 update should come soon (around January 2021?).... I take it that they will reinstall all their garbage in the OTA update... And we will have to decrapify again!?

Yes I guess for a major update it will maybe reinstall crap like "tips" from Samsung. But i've done this using beta4 OneUI3.0 and it work very well

The phone shown me an update yesterday (01/01/2021), OneUI3, Android 11.
It updated without any issue, and all my apps and things are properly there after.
One strange thing is it was allegedely updating 470 apps on my phone, I don't remember having so many.
Another thing to notice, is that I did not notice any new garbage apps after the update. For example, some emoticons junk was not reinstalled. Also, the default keyboard remains Gboard, like I set myself before the update.
Anyway, time to check now, in details.
Verdict: # Total applications: 421
Some junk have been installed again during the update. (after my previous cleaning, I was at:
# Total applications: 361)
I don't see the same type of junk as it was before, like Netflix apps, Bixby...etc... So it's rather strange.
One horrible app I found is "eBay Partner Attribution". What is it? Affiliate marketing is a referral program where sites pay commissions to affiliates who send traffic to their site that results in a sale.
Well done Samsung, installing junk to get additional money...
App killed on sight (com.ebay.carrier).
I also removed com.google.android.videos.
That will be all for now, don't have the time to do better.

I think knox junk tripping is only if you replace your bootloader:
Knox
I think removing the apps only is not tripping it (anyway, if it is, my phone is fine without it).
It depends what you mean "safe" anyway, if you are talking about some features that might not work, or a broken phone for example.

Thanks, im not sure if you should put the Knox app in the safe list.
