System app disabled and still crashing - Nexus 4 Q&A, Help & Troubleshooting

Hi
I disabled hangouts app on my stock 5.1.1 rom 'cause i dont use it, but every few hours it crashes without a reason (i think that if the app is disabled, it shouldn't be running in background).
I know that it's a system app and I could uninstall it easy using root privileges, but this situation doesn't appear in other smartphones.
So how can I fix it ? The pop-up notification is annoying me :')
The problem is related to stock nexus4 rom or is just a global bug ?

In settings->security->install apk from unknow sources is checked
help me?
Are you running paranoid. If so you need to disable halo in order to install an app that way

No
I have rooted phone, stock rom 4.2.2., stock recovery, stock kernel
this was happening to me before but after scrolling down-up through permissions i was able to tap INSTALL button
anyone?
Some apps will cause this, I had it when I had Screen Adjuster running, stopped it and I was able to install.
Specifically, any apps that you've given permission to draw over other apps can potentially cause what you're experiencing. E.g., screen filter and other floating apps.
kien and ohyeahar tnx for help, i solved it by uninstalling twilight

Found way to disable undisable-able bloatware non root lolipop

First off I am running lolipop and have been working to find a way to disable bloatware that you don't want. I can't root as I'm on a att s5 lolipop...
finally found out how to get those apps that can't be disabled disabled.
Instructions:
1. Find the app that your wanting to dissable... let's say for example My Magazine.
by default in lolipop this app can't be disabled without root... frown face.. bad day...
2.Search for an apk file online for that app you want to disable.
And install it.
3. Here's what happens now... since you just updated the system app yourself, you now have permissions over it.
So to disable the app go to app manager and look under downloaded. You will notice that now the app that previously could not be disabled... now can be. You also have the option to Uninstaller the update... update only unfortunately but oh well.
Now you have just succusfully disabled My Magazine or what ever other system app that can't be disabled.
If you need any help just ask.

Nice idea, but sometimes it may not work. Now i have no idea as to why My Magazine worked but when installing other system apps it is bound to meet a signature conflict if the apps are the same version and completely untouched by any third party. If a signature conflict appears it will be impossible to install that system app manually.
I have only seen this phenomenon on S2 and therefore i have no idea if the same principles are embedded in the S5 but just a tip if a signature conflict ever appears while trying this method.
Anyways, good find :good:
Thank u sir.
Yes oddly enough my magazine was my first attempt and didn't even check version and had success.. noW that I see this method is possible... I'll just have to find other versions of the apps I want to dissable. I haven't had any luck finding newer versions of the apk files tho
Any thing u think might work. Modifying the apk perhaps so it may possibly install as an update?
I'm just happy to have mymagazine no longer starting up and running in the background

If you modify an apk file you will need to create your own signature when recompiling, android won't like two of the same apps (same package names) but with two different signatures and the modified apk file wont be installed.
So try your method as long as it goes. who knows, maybe you wont encounter a signature conflict.
As long as the app is disabled a signature conflict shouldn't matter tho right? Because the app is disabled and all?
I'll keep a look out. The version my magazine I'm showing now is 3.0.0
In app manager I have orion to uninstal the update so if something does happen I'll remove it
You seem to know a good bit maybe you can help me with something.
Is there a way I could take
expample.apk version 1.0 and edit it somehow and trick it and or android into thinking it's say version 1.1
This would allow me to install the same version over what I have now.. then perhaps be able to disable it..

[Q] Unable to uninstall Wakelock Detector

TL;DR Google Play has only the Open option and no way to uninstall app
After updating my I337M from rooted NI2 Kit Kat to rooted OC4 Lollipop, I was unable to properly run Wakelock Detector. It was stock to stock so I didn't wipe factory settings.
Googled a suggestion to move the APK to /system/priv-app so I did that but still the same result.
Now when I want to try uninstall (so as to re-install) there is no option. Under Manage Apps the app isn't even listed. The APK is still under priv-app and I deleted it... still shows up in app drawer.
D'Oh! What else can I do to uninstall it properly?
Sent from my SGH-I337M using XDA Free mobile app
i have the same problem
so ticked off. same here. even paid for the full version because sometimes that fixes issues like this. I can disable or freeze with titanium backup pro but can't uninstall. i think the problems happened after converting to system app. so now I have 2 frozen apps I want off my phone. On top of that the app stopped working after converting to system app. I get an error after the app loads. I emailed the developer and am waiting to hear back.
This days the application App2SD is able correct install Wakelock Detector as private , and it is able to uninstall it if it was installed as private .

Safe to uninstall Feedback?

I want to uninstall the Feedback app as it drains my battery a lot, not to mention it runs in the background when Ive never opened or used the stupid app before! The question is can I uninstall it without having any side affects?
Uninstalling system app may result in OTA update failure, other than that no problem should occure.
Unfortunately this is the only built in app added by Xiaomi you can't disable.
Clear the data, set the switch to never run in background and don't open the app again, should help reduce battery usage.
Feedback (and also Camera) is a system app. So uninstalling it could make problems with OTA. Just disable it.

Feedback can't be disabled, that's why I gave the advice in the post before yours.
@kudos1uk I just tested it and you are right. But you can disable it with Titanium Backup or Greenify(I don't know how they work without root) or Brevent that should work without root: https://www.xda-developers.com/brevent-is-an-open-source-alternative-to-greenify-works-without-root/
I don't know if OTA works when the app is hibernated. Maybe, it's better to enable it before updating Android via OTA. Personally, I have the app Feedback activated. It doesn't slow down my phone...

You can't disable a system app with TB without root.
The OP only needs to follow the advice in my first post, if running in background is disabled and you don't start it all will be fine.
If cant disable Mi services and feedback, you can uninstall the app
You can uninstall s&f app by ADB tool using your laptop.. My question is that is it safe??

Downgrade system app

So, I stupidly tried to upgrade my oneplus contacts app from 3.4.2 to 4.0 (which I assume is for android 11) and now the app just force closes every time and is unuseable. I'm on android 10 10.5.12AA
On google I used to be able to uninstall updates but I don't see that with the oneplus system apps.
Any tips?
TIA
Nobody?
Still can't use oneplus contacts app. It just force closes every time.
Had to download google contacts, which is ok but I've been enjoying using more of the oneplus apps.
How did you update? Did you remove the system app and then installed the new version or just simply installed the new versionv without removing?
If latter, just disable the app, it'll tell you that all updates will be uninstalled and the app will be restored to factory version. Once done, just enable it again, and don't update.
it was the latter but updates don't uninstall when you disable the app.
That's the way it always worked on my google phones.
I just tried again and it just disables the app and nothing more.
Thanks for trying to help.
