Samsung A20 Stock ROM, No Root - Package Installer Issue, Cant Install APKs - Samsung Galaxy A20 Questions & Answers

This is my moms phone first off, she got it used from my sister. When she got it it had been factory reset but since my sister forgot her PIN part of setting the phone up for her was to log in with my sisters old information first to make sure it wasnt stolen. I mention this in case that might have had some bearing on anything.
The issue is when trying to sideload apps onto the phone and you tap on an APK file it comes up with the Text, Image, Video, Other popup as if you tapped on Open File As. Its as though the Android Package Installer thats built in isnt associated with APK files kinda like youd have file associations in Windows. As a temporary workaround I have gone and grabbed a third party APK installer app off the Play Store but that still isnt ideal as to install anything you have to go through that app then.
She has ES File Explorer installed and even tapn hold on an APK and using ES's Install option it uses the built in Package Installer so it doesnt work. Oh and Unknown Sources is of course enabled.
I would like to fix this without completely reinstalling the entire ROM with ODIN if I can help it or completely factory resetting the phone again.

[Q] APKs won't sideload via adb or a file manager

So I am trying to load a couple of apks I have and it's been no go. On my Epic I usually just dropbox, open, and install. I tried that and initially got the security message. That is already taken care of via nookcolor tools. So that isn't the issue. My issue is every time I go to install I go to Astro, open the file via the "open app manager," it takes me to the info install page...I click install and it loads into the package installer, excellent...and then it just stalls and the progress bar runs and runs but never progresses. This has happened with every apk I have now tried.
Okay...so I figured I'd just go the little more involved (very little, no need to be that lazy, right) route and adb install. Well carp. All goes well, I adb install blahblah.apk and it starts rolling..."570kb blah..etc pkg /blah/temp/blah"...and just hangs there...never to give me the gratifying "success" message. Again, I have tried this with different apks that I know work and the same results. I restored to stock and rerooted, just in case. Same
I am running stock rooted (manualnooter) at this point, just got the nook day before yesterday (one of the many who jumped at the refurbs). Market apps download fine. I'm a blue dot, if that makes any diff. Likely not but meh.
I have searched and googled and not found the answers...but I know I am missing something elementally simple. My luck I'll look like an idiot and it will be a "did you check to see if you had any gas?" broken down car scenario. I'm okay with that, as long as I'm running again. I'm pretty sure I checked all the out of gas scenarios but I likely missed one or two so... any help is much appreciated. Thanks a ton...
I should know better than trying to write before coffee
Well, My answer is not a "check gas" answer. It's pretty dang weird.
1. Download ES Explorer from the market.
2. Start ES Explorer, hit Menu>Settings. Goto Root Options (NEW) and tick both check boxes. Hit allow when it asks you to.
3. Go back twice, until you see your sd card contents. Find the APK on there and select and hold. Hit copy and then hit the 1st button on the row of buttons (it's an icon of an sd card OR a Home icon) If you see a data folder, go in to it. If not, hit the 1st button again.
3. Once in the data folder, go into the app folder. Pull up the little white tab on the bottom. Tap the APK you wanted to install. It will copy. Once you see the APK's icon in the folder, hit the home button and restart. That should have installed it but it is a slow method. Note that you can Multi-Select APK's by pressing the Multi-select button and pasting them all in the /data/app/ folder.
are you sure you have side loading checked
Settings > applications should be the top box.

I think he already took care of that. And he is on stock, so there is no Applications setting.
ikingblack, thank you, thank you!
Not sure why but by doing this it somehow unsnafued the package installer as well (fingers crossed). I went through your instructions with a known good apk that would not install for anything before. And there it was after the copy, paste reboot etc. Not too much to ask for...still was confused as to the why of the normal package installer method not working. So I decided to give it (package inst) a go with another known working apk (I had just tested it on my epic) that previously wouldn't install, repeatedly, and now it installed just like it should. Scratching my head in wonder. It shouldn't be the reboot, as I have do so many times...the only difference is the install instructions and adding ES (I'm leaving astro behind I think). All I know is it is working and I am a happy camper (tent is in the back yard...) Thanks again! cheers!
Sure. Also, you can select all the APK's using the 2-file icon at the top and tapping the APKs, then press-and hold on one of the APk's and then go to data app, and keep tapping the APK's you wanna copy. And then reboot. Enjoy your Nook!
Thanks for this, it fixed it, but I don't know why.
I suffered this issue on my dell streak.
It was working fine a couple of days ago when I installed GetJar.
Suddenly today for no reason I can determine:
All APK's I tried the install button in the package installer was not grayed out, but it would not respond when pressed.
I've just been setting up my streak again and installing a lot of software. I'm guessing something must of gone wrong.
Someone on another post suggested JuiceDefender may have caused it but I've not installed that recently.
In my case I did:
(1) Installed esFileExplorer
(2) Copied an apk to the folder /data/app/ as described above
(3) restarted the phone
This did not install the app for me.
(4) Tried running the apk file again. Suddenly the Install button is clickable again?! The app then installed just fine.
(5) Tried a different apk (without copying to /data/app/)
Now that will install fine?!
This is really weird. I can't replicate the issue now (which is good!)
but I also can't tell which action fixed it.
As said above it may have been installing esfileexplorer and giving it root access.
It may have been the act of copying the file that reset something.
It wasn't the reboot, at lease not on its own as i'd already tried it.
Regardless, thanks for the info.
If anyone sees this issue again you might want to just try installing esfileexplorer and see if apk's will then install.
This might help us identify which bit of the process is creating the fix.
Just found another suggestion if anyone is interested:
Some suggests using the 'Fix permissions' option of Titanium Backup. I have no way to test this.

Fixing Problems with Google Apps Force Close

In the dev forum, there is a helpful post on how to root and then install the google apps:
http://forum.xda-developers.com/showthread.php?t=1349902
Like others on the thread, I had a problem with the market and other apps force closing all the time; what's missing from the instructions there is that when you change the permission of the apk files copied into the /system/apps directory, you must also make sure that they are owned by root. In my case, they were owned by the OS user on the machine I connected the kindle to when I transferred the files.
So, in root explorer, after you change the permissions to rw-r--r--, long press again on the file, choose Change owner, and change both the owner and the group to root.
I'd be stoked if this actually worked for me. It's really weird, everything was working fine this morning then it just randomly started force closing google services framework on me left and right. Now I can't even get talk to work at all.
Damn, I feel stupid. I made the mistake of removing the stock system calendar and contacts files. I found the system dump file and put everything back but either I forgot to install them or the system uninstalled them on me. Anyways, installing solved the problem.
Now I'm having another really weird problem. I do the initial install of the market then I have the market up and running once I do a reboot. After any subsequent reboot, market automatically uninstalls and I have to use TiBackup to reinstall it. Fortunately, once I restore, I don't have to reboot again but that is a major pain.

How to download apps with no 3g or wifi on the phone its self?

As the title says I have an xperia play but the wifi isnt working. Ive done a factory reset, used pc companion to reinstall the software and even installed a custom kernel and rom but it wont even turn on the wifi thus I cant search for a router.
Is there a way I can at least download the apps i want such as
fpse
screen filter
various games
themes
ect
even with the broken wifi on my phone.
Ive had a search online and Im either wording my search wrong or its not possible to do what I want.
Also any advice a possible fix for the wifi would be great but Im assuming that its the hardware thats broke.
With usb cable, you may download app and install with adb or any pc companion software
You don't have warranty anymore?
Well, you can download the apk of the app and then copy it to your phone. Then just install it, shouldn't be too difficult.
Only problem could be, if you don't have any file explorer on your phone
Google the app you want , download it in your desktop and transfer to your phone. Install it via file manager
Sideloading, How I do it.
I haven't seen anyone mention this yet.
You need to first go into your phone settings and enable Unknown Sources found in the Security tab. Unknown sources will enable you to install apps without the Play Store.
Then connect your phone to your PC with your USB cable and select either Storage Mode or USB Mount, depending on your phone it will be labeled differently.
Your phone's folders will appear on your computer, simply drag the .apk file into your phone to transfer. Once the transfer is complete, remove the USB cable or unmount the phone.
Finally, use any file browser on your phone to find the .apk you transferred and click it. Your launcher should automatically ask you if you want to install the .apk
Note: App files are taged as .apk so any app you download should be something like Facebook.apk. I personally just do a general search for whatever I want and then include "apk" in the search field. You will find 100+ websites where you can download various apps, but the trick is, you usually have to do your research on the Play Store first to find out what the latest version number of the app is because there are mostly outdated versions floating around the internet.
I guess the best part about side loading is that the Google Play Store can't filter what you install. So apps that were previously not compatible could possibly run on your device no problem. Like Netflix used to be incompatible officially with my phone but I sideloaded it and it worked fine. Netflix finally released official support but the fact is I got it before everyone else.
as they said, you should have a pc and it have the apk file to download it to phone

question for Galaxy Express 3(not listed). Trying to bypass google verification

so my friend found a samsung galaxy express 3 from at & t and wanted me to set it up for him. so he gave it to me, first thing i did was factory reset it in recovery mode. Then problems started. I dont have the previous owners account so i need to bypass the google verification. But i have no idea how. ive tried the side sync method, the open with option never showed up. this phone doesn't have usb hosting so i cant use an otg cable. i tried the real term method, just an error when i put the codes. i tried the no computer methods, i can get into ultra power saving mode, but thats it. with the other no computer methods it comes down to restarting it, and when it comes back on theirs camera access but for me when i restart it its locked, but no camera or phone access. ive tried every option i could find and even tried installing a stock ROM, succeeded with the stock rom installation thinking it would remove the google verification but still didn't. does anybody have any ideas? i cant enable USB debugging. so i dont think i can root it and install a custom rom and disable it. at least i think. im new to this stuff so if anybody has suggestions for me then that would be great. Thank you in advance
Google frp bypass. Methods have changed, due to patching. You need to research the most current method. I used Rootjunky's method back in the fall of 2016. Worked like a charm. Consisted of a phony call through an emulator, triggered a request for contact storage, led to browser opening playstore for a vcard app. Download frp bypass app instead, viola!! Imho, too much work for that phone.
I managed to get into chrome. Now what?
So with a bunch of messing around I managed to get into chrome through the emergency call but I'm in chrome. Which is how most methods work is through chrome. U install an app then run it and ur able to bypass it pretty much. But I can't install any apks. When I download a file it ask if I wanna download it, then starts it but never prompts me when it's done so I can't open it and install it. If I redowbload the same file it lets me look at the downloaded files and I can even get to the SD card. But if I tap on anything that's not a folder it kicks me back to the browser. So how could I get on the Samsung store to get es file explorer or install apks? Any help would be great thanks
I've had success setting up a samsung account installing es file explorer, then putting the app needed on sd card or Bluetooth it via a settings app. Rootjunky has the apks. But yes the 911 loophole is there if you don't have a sim to do a realterm dialer method

Install button not working!

Well Hello there!
Everything was working fine but then that was the problem because devil was prying its eyes on my phone :laugh:
Now I can't click on install button when installing apps from apk file. Cancel button is working fine and also installing apps from app store have no issues as well. I have tried installing other apps and on some them install option is working and those are the apps which do not require any permissions. So the apps with any permission access have problem with Install button.
Everything was working fine but the I installed the last app named Network Monitor mini downloaded from other source and this app has a permission "Draw over other app and Modify system settings" maybe something fishy?! and also while I was typing here, Lg keyboard is not working properly like its automatically autocorrects on its own, turns caps, etc. I was hard time while typing here.
Any help? :crying:
Hi, have you tryed to uninstall "Network Monitor mini" or disable it (the background service) before installing something ?
or you can look at this thread : https://forum.xda-developers.com/showpost.php?p=73405029&postcount=5

Tried but no luck :crying:
I've tried everything I could. Well there were some topics like this that were around 4 year old which caused due to some apps like lux, screen dimmer, etc. but I don't have anything like that and also this keyboard is causing problem a lot like auto typing, cursor jumping somewhere else, etc. Maybe factory reset is only thing left. Thanks anyway :good:
I had the same Problem a few weaks ago.
To fix it i first download the .apk file again. Then i opened a File Manager (for me it's Es File Explorer) went to the Download folder and clicked on the .apk file, the install Button didn't work. Now You have to click on the recent Apps Button in your navbar and switch to another App and directly switch back to the File Explorer, where the Installation windows is still open. Now i could press the install Button.
Hope this works.

Well I did factory reset and the problem was still the same because the first app I installed was ES file explorer and guess what this problem was only occurring in ES file explorer :laugh:
Everything is working fine when I open any apk file with default file manager. :good:
Thanks bro!
This is happening to me and it's the first time ever. I thought the phone was knackered again. I got into a boot loop when I flash the Magisk 17.0 zip from TWRP (the recommended option to install after DL was not visible). Could not get out of boot loop but was able to boot into TWRP so I just flashed Fulmics again (easiest option for me) and restored some backups and downloaded some APKs. Only one APK would install normally but if I pressed the power button and then woke the phone up again with the power button it would work and the "Install" option would no longer be greyed out.
Does anyone know why this is happening and if there is a permanent fix?
