Installing android app (help) - Android Q&A, Help & Troubleshooting

Hi everyone,
I have bloatware app installed on my android head unit. I want upgrade it to newer version but it fails.
I tried to uninstall it by using different methods. All fails. Then I used universal android debloater it finally uninstalled. But seems not uninstalled completely. When I tried to install the same app manually fails. I tried (adb install file.apk) command and got:
Package signatures do not match the previously installed version.
When I go to apps> system apps, I can see the app there but it’s greyed out and got (not installed on this user)
I tried : adb uninstall [PACKAGE_NAME]
Also failed. Error ( deleted failed internal error)
Please help me to solve my problem. I really need to install the new version of the app.

Run SD Maid Pro - requires Android is rooted.
The app comes with several modules, including a so-called "corpse finder" that detects unused and temporary files and deletes them.

How to disable signature check?
I tried many ways but all failed, I hope if I can change the package name so I can install the app without any issues.

The package conflicts with an..... error while installing apps

Hi Guys,
I tried to install WA+ in my S7(non-edge) phone but I am getting an error, The package conflicts with an existing package by the same name. Since there is no way to uninstall the preinstalled WA, I disabled it but still the same error is there. I have seen people having WA+ in their phones without rooting or deleting the preinstalled version. What should I do?
Thanks
To install WA+ in phones which got pre intalled WA you got to remove the pre installed WA, you can only do this by rooting your s7.
I want you to follow this step
1. Rooting your phone (rooting voids warranty)
root your phone from this link(rooting)
2. After rooting your phone install System App Remover(links given below), unzip the file, install the apk, give su root permission and uninstall stock WA.
3. Reboot your phone.
4. Install the latest whatsapp+ from the link below.
Enjoy!

Uninstall pre-installed app (not disable)

Hi,
Is there a way to uninstall or overwrite an existing app?
I have a phone that came from a carrier with a pre-installed app.
I have a different modified version of this app that I'd like to install but because this package already exists (even though I have a newer version) it's giving me an error "an existing package by the same name with a conflicting...".
I do not have root so unable to uninstall existing app.
Is there a way to overwrite it?
Have Android 7 on Galaxy S7,
Thanks!

Uninstalling preinstalled apps needs root or atleast custom recovery installed.
You can also disable signature verification for package manager but it also require root

Is there a way to change an app signature that I'm trying to install so it will be different than what's installed?

can't unistall system apps

Hello. I've just updated to miui 9.5 global stable. I have also flashed twrp and rooted with superuser. The problem is that I can't unistall system apps with system app remover pro, althouth that with previous miui didn't have this problem. When I try to unistall any system app it says ''failed umistall''. I have also tried some other apps as root unistaller, but the problem remains. Please any help.
You could try adb, but be careful. You need to know what to uninstall and what to not uninstall. Download platform-tools, use a command prompt (cmd) to access the platform-tools folder, connect your phone via USB debugging, enter adb devices into the command prompt, and list all the packages with adb shell cmd pm list packages
All the apps on your phone will be listed as their package names. You can uninstall (or disable) these packages by entering pm uninstall -k --user 0 <name of package>
You can disable packages (and renable them if something goes wrong) with command pm disable <name of package>
Uninstalling works whether you're rooted or not. I think disable only works if you're rooted, but IDK.

The problem with this method is, you need to know exactly what to uninstall or your ROM will get screwed up. Like UI will stop working. In that case, you have to factory reset and start again. So backup all your files before attempting this.
I'd use Titanium Backup that way you can initially backup the app before uninstalling and delete later once you're 100% sure you no longer need it (although save the backup to a Micro SD or PC anyway).
If you're going to use ADB then the PC Inspector app will help identify the correct app to uninstall.
Edit: Are you 100% sure you've got full root? Have you checked with something like Root Checker (joeykrim)?

I did try it. I'm using system app safe remover [root] from playstore. My Miui optimization is currently off. It still says 1 failed uninstall.
Trying disabling YouTube? I used hidden miui settings app and from there I could disable YouTube.

I tried that too. But I still can't install the vanced youtube app. Because even if its disabled, its still a system app and cant be installed over
So update: I tried with a multitude of apps including SD maid and titanium backup and it still failed. In some apps it said "the apk cannot be located" ?? So I enabled the app and installed updates and tried again but still kept saying the apk cannot be found.
So I tried adb. I tried the "pm uninstall –k —user 0 package:com.google.android.youtube" and it said "Failure not installed for user". What?? So what am I supposed to do now?
