Is it complete safe to disable apps in system setting / app section? - LineageOS Questions & Answers

I found that sometimes I can't disable some apps, but sometime the disable button become available, from gray to clickable. I guess they are grayed out because of they are in used in someway, but once an app's disable button is clickable, is it completely safe to disable it? Cos I feels that if I use root to disable an app which is not able to disable currently may cause some weird issues and perhaps will drain more battery.
For something like Browser, I'm quite sure that at least if I install another browser and grab the default app slot, there won't be any problem if I disable the built-in one, but a lot of system apps are able to disable without root, I just wonder that can I disable them all by just losing the functions they provided without cause weird issues?
BTW how can I disable AudioFX legally? Since I never used it

[Q] Unable to install 3rd party apps

I get no action when I press the install button, though the cancel button works. I have the allow unknown sources box checked in settings. I cannot install using either ES File Explorer, or the stock My Files application.
I have also done a battery pull, and cleared cache in recovery.
Anyone have any idea how to correct this?
I'm having the same problem.
Is there a solution to this?
I'm now on 5.1.1
did u make sure unknown sources has a check mark under the developer option?
OMG!
Problem solved.
eyesofice- yes it was checked.
What I got was the option to "cancel" or "install" but the install button would not worked. It turns out it was due to running Lux (an auto brightness app). Turning it off let me use the "Install" button. I found a mention that programs that use screen filters like Lux will disable side loading because malicious apps could spoof the user into clicking on what looks like a harmless button but really it installs another app instead.
Hope this helps someone else
good to hear glad you solved it.
I use twilight myself and I have noticed that if you are on Lollipop that you will have this problem. So far I have noticed it on 5.0.1 and 5.1.1. In fact I believe that twilight itself had a pop up message I dictating that with Lollipop this was a known issue.

App launch...

My previous Huawei phone had some extra power/app management settings but in this new EMUI it seems expanded and more difficult to understand.
What I really want is to just let apps do what they want or let Android manage them. It seems, though, I either have to let Huawei manage them automatically or manually manage them by those three settings (allow auto start, allow start others, allow background). Is this correct? Am I missing something on this?
I also disabled the power usage notices that come up for apps (per app). Wish there was a universal disable for that.
The manual adjustment screen.
Are you running a L29?
On my older Huawei phones, I always turn everything on. I only have the apps I need, and I trust that none of them are malicious, so I turn them all on.

That is kind if my thinking too, but the feature wording is awkward. I am not clear, if I just turn auto to manual (for all) then does that let them ignore Huawei's thing? Also, it seems any new app defaults to automatically controlled.
It also isn't real clear on that second setting page, the manual controls, does that toggle on mean manual control (not Huawei) is on or does it mean auto (Huawei) control is on? In other words, does that toggle mean yes the app can do what it wants or no it can't?
My current thought is that if auto is off on the first page and I use the second page grant apps the permissions that I want (those checked can do that thing) then apps will run without Huawei interference and according to their own setup and whatever Android limitations exist (and of course, whatever limitation those checks and unchecks would imply).

Yes it is awkward how they word it. Huawei software kind of sucks. On older phones it was very aggressive with permissions and killing processes. Believe it or not, this has become easier over the years.
If you have hundreds of apps, then maybe pick and choose what you want. If your like me who only uses maybe 20 or so core apps, then I'd turn them all on.
On my AL00, after the update, the list is no longer there. You need to go into battery usage and then click on the individual app, then app launch.

latest oneplus firmware very antagonistic to call recording

So, oneplus always had the ability to enable call recording, they just don't show it to you based on what country you are in / sim in use. However, there are ways via adb commands to enable it. They would have to be run fresh on every boot, but there are ways to automate it. However, now, it seems that oneplus is being much more active and during runtime disabling it randomly (at least popping up a message telling you that it is). I am pretty upset with this change that came in today's hotfix.

There is a Magisk module (enable oos native recording) that enables recording and survives reboot. Just remember to uninstall it prior to any oos update, you can then reinstall it.
I try to stick with stock, as really had no issues. I was able to create an automate script that worked without rooting / modifying the stock firmware that reenabled recording on each reboot. The problem is, now the firmware is actively disabling it during runtime, not just as boot. my "solution" right now is that it seems to be tied to the notification, so if I never dismiss the notification tell me that its disabled, then it doesn't disable it in the future. Not a good solution to leave a notification up (As easy to dismiss by accident). but it really annoys me that they made such an antagonistic change.
I've created a workflow in automate that enables recording on boot and reenables it every time the notification of recording disabling comes up and dismisses the notification. Annoying, but seems to work without any rooting needed.
but i'm so annoyed that they changed this. I use t-mobile's wifi calling for my US SIM (I'm overseas), so everytime i drop out of wifi, it triggers as it seems to trigger everytime there's a "service" change of some sort on it.

Disable Notification Screen Wakeup?

Currently using the Note 10+.
Samsung messages app and specific other apps keep waking up the screen when there's a notification.
I have searched and tried every method that I have found so far and none of them work.
What am I missing here? Why is there no option to prevent ALL apps from waking up the screen upon a notification? How is it that certain apps like Samsung messages and Realtor (real estate app) and a few others keep waking up the screen?
AOD is on. I receive notifications from other apps perfectly fine and an icon will appear in AOD, but these other ones will wake the screen.
If you have screen saver on and you receive a message through the night, guess what, your phone screen will go into screensaver all night with the screen on.
I have to say I am amazed at the fact that this isn't an easy question to answer unless I'm missing something completely, and what's even more amazing is that this same question has been open LITERALLY since 2015 amongst other Android devices without a working solution.
If you know the answer to this, and I don't mean you kind of sort of want to suggest things, trust me I've taken every suggestion at this point to no avail, I mean if you TRULY know the answer to this, please chime in.
Suggestions like use other apps and whatever is not an option considering this happens to multiple apps and seems random meaning you can't keep replacing apps. Suggestions like turn off notifications entirely OBVIOUSLY is not an option.
My 2 N10+'s don't behave like this.
What OS version?
That 3rd party real estate app may have caused it. I don't allow trash apps on my phones because of multiple issues they can cause. Sometimes they will permanently alter hidden settings that will remain even after uninstalled. A poorly written app can cause a lot of trouble...
Clear system cache.
Try clearing lock screen data.
Check all notification settings... again, including lock screen, edge lighting and associated 3rd party apps (turn off background battery/data usage).
Try running it in safe mode at night to see if this stops it. If so, it's a likely 3rd party app.
Find the root cause otherwise it will likely reoccur if you do a factory reset... play with it.
