[Q] Unable to install apps from Play Store

Hello,
Post rooting (repenting it already) my Samsung Galaxy S Plus (GTI9001), I am unable to install any apps via Play Store. I am able to install apk's from the SD Card though. I un-rooted the phone but problem persist.
When I try to install any app, I can see the app being downloaded on the notification but the moment the download completes nothing happens. When i go to Play Store > My Apps I could see that it still says downloading though the app is fully downloaded. I guess some permission issues here. Please help.
I have already cleared Play Store cache and tried.

Hello,
Which Rom do you use? Maybe you have to root it again. Usually you can fix permissions in CWM. Have you tried to restart after "Download is finished". For Me it was working on my Asus EeePad.

Chris, I am still on stock ROM and I am not likely to go for a custom ROM since there are not much good ROM's available for Samsung Galaxy S Plus and Yes I tried multiple reboots. After reboot, on the notification it says that app download failed due to some error with a number.
Thanks for your reply.

Same issue
Reyolin,
I have had the same problem on my Samsung Galaxy S Plus but it has only started today. Mine has been rooted for about 5 months now, since I first got it.
I did a search using EStrong File explorer and it found a file called "downloadfile.apk" in /cache (I assume this is the file as it is the same file size as stated in the Play store. However, when I tried to run or copy it it had disappeared.
It's almost like the APK is being downloaded and then being deleted before installation actually occurs.
I think rooting your phone and the inability to install apps is just coincidental.
I will do some more playing about and see what I can find (I also already tried removing the Google Play updates (to go back to the old style Market). This still did not solve the problem.

Please use the Q&A Forum for questions &

Thanks ✟

Exactly same proble
Hi,
I have exaclty the same problem (galaxy s plus), rooted 5 month ago and problem started 2 days ago...
I updated superuser at that time and tried to update the su binarie but it fails on validation of new su and stopped (not replacing old su), this is the only thing I can remember of. root is still working with old su. Maybe the cleaning needs to be done ?
Has someone found a way to fix this?
edit:
after some investigation, this is what happens:
if I try to install one app from play store, it is downloaded correctly and then nothing happens.
the file downloaded is in /cache/downloadfile.apk
If I copy this file to /sdcard/external_sd/downloadfile.apk and run it manually it installs correctly.

galaxy s plus specific issue
i am having the same problem since morning and i also use Samsung galaxy s plus, so certainly the issue is phone specific.

Good news! Problem solved for me
Hi,
I contacted google play support and her was there answer:
Thanks for contacting us and I am sorry for the delay in responding.
We've gotten some reports that users with Samsung Galaxy S Plus devices running Android OS version 2.3 (Gingerbread) are having trouble using Google Play. We're aware of this issue and to solve it we recommend you to uninstall updates to the Google Play app by following these steps:
1. Tap Menu > Settings > Applications > Manage applications
2. Find the "All" tab
3. Scroll down to Play Store and tap to select
4. Tap "Uninstall updates"
Thank you in advance for your patience and understanding.
So I followed this and it works again!
Here are the steps after doing google recommendations:
- click google play icon, it will open old google market
- install an application, for me it worked again!
- exit google market
- click again the google play icon, it will ask to accept google play license
- click yes and then try to install another app, it worked again!
Hope this will solve also your issues,
Stef

I Just had the same problem. Here is how I fixed it,
- Uninstalled updates for Google Play
- I added a New Google Account.
- I Then signed into the new Google Account, Then Sign Into Your Main Account
And "BOOM" problem solved.

[Q] Two app problems after flashing

Good Morning,
i had flashed my Samsung Ace with cm10 because i want to use Threema.
But now if i go to the google store, i cant download threema. It shows the message that my Phone isnt compatible.
Threema requires a Android 4.0 or higher and cm10 is a a Vanilla Android.
It seems that the store doesnt look at the android version but the phone model. How can i install now Threema?
And my second question is: Up to now i used Xabber as chat client. After flashing cm and failing at the Threema installation i tried to
install Xabber again but the store means it is already installed. How can i use the app or deinstall/reinstall it?

No one can help me?

Gear S2 (Gear Manager) works on non-TouchWiz Roms(CM, RR, Lineage etc)

Hello,
I have a Gear s2 smartwatch and i was using it with my original TW (TouchWiz) Rom.
But You know TW is very heavy and battery eater rom like a monster.
So I was trying another lightweight roms like Resurrection Remix, Lineage OS etc.
But the Gear Manager app says met that “your phone's operating system has been changed in an unauthorized way…”
So i search and find this for fixing to work gear manager on other OS which is not TW.
First of all, I am not responsible for bricked devices, dead SD cards
Lets go:
After flashing a new rom to our device, gear manager says like that "your phone's operating system has been changed ..."
For Fixing This:
1- Install that 5 apps newest versions to your phone(normal way or Titanium backup)
Samsung Gear, Gear S Plugin, Samsung Accesory Service, SASytemProviders, Samsung Billing
2- Open your file Explorer which has root Access and find build.prob file in root\system directory. Backup it on your sdcard. Be careful while editing this file
3- Then open build.prob file and find all “samsung” words to “htc”
4- IMPORTANT NOTE: Dont change This section ro.telephony.ril_class:SamsungExynosRIL (just leave it original)
5- Save it and restart your Phone.
Thats all
Now open Gear manager app and connect to your watch.
Worked OS: Resurrection Remix 5.8.5, Lineage OS 14.1

I don't suppose you have the apks for these apps, or links? I'm currently having issues on my note 4 with Resurrection Remix 5.8.5. I installed some modded apks, but still having issues.
Thanks!

Doesnt work. app not compatible ... GalaxyS5 (S520-f)

Super great tip!!
FANTASTIC!!
Was about to ditch my Gear S3...
:good:

you guys could download the app i listed in dev section to make gear work on any device regardless of os and ram limitations

In case anybody has the same problem, this thread solved all of my issues. I have a Nexus 5 with lineage OS, and I could not get google play store to install the app. It didn't show up in play store on my phone, and online it said the app wasn't available for my device.
Fortunately [B @j to the 4n[/B] has made resigned versions of all three necessary apps (gear plugin, samsung health, samsung accessories) - and the Samsung Gear S3 is working flawlessly again.

Thank you very much @j to the 4n.

Dude..... You are a legend ???????????? it worked for me.

compatibility problem

Dear,
I have a problem installing an application on my new Huawei Mate 10 lite. I installed the open, but on opening it says the device modal is not compatible. Is there a way I can have the application running on my device? the application is a dictionary and I am in a dire need of it, for I use it for my studies. I would appreciate any help that would get the app running. Thank you

You're trying to install it from Google play or from an APK file ?

I installed it as an APK file. It was working fine on my old Samsung Galaxy S5, as I had it downloaded from Galaxy App Store. The latter is presumably the only place where this application exists for free. I downloaded it from Galaxy App Store, installed it on galaxy s5 and shared the APK file by means of another sharing app. It installs, but it does not run. It says "device modal not compatible".

Yes , that's a kind of " protection " for Samsung , I had the same problem with gear fit manager , an app from Samsung to make a smartwatch work . That was the only way to make it work but Samsung didn't allow to run this app on low-end Samsung devices and others devices.
Unfortunately , I can't do anything.

I believe that there should be a way to install it, since it is not an application that Samsung built. The only thing is that it is offered for free by Samsung. I can't find it any elsewhere, at least the same exact version that I am looking for, but on the Samsung app store. So, I tried to share it, but it never worked. I saw somewhere on this website how to install it, but requires the phone to be rooted.

Yes , it may be the case , because I think you have to fake your device name or something like that.
But I haven't the sufficient knowledge .
Maybe a longer search will be helpful , I hope you'll find the way to do this

Samsung Gear S2 not working on Nexus 5X running LineageOS 15.1

Hey
I rooted my LG Nexus 5X yesterday and was able to install lineageOS and run it successfully. But today, I noticed that I am unable to get the Gear S2 to be paired with the phone in the morning. And when I tried in the evening, I uninstalled the Gear Wearable app(which isn't compatible with the device according to Play Store, but I tried an apk which installed in the morning) and tried reinstalling it with the same apk, but this time, it didn't get installed. I just keep getting "App not installed" when I try to install the apk with the inbuilt package installer.
Thanks for your help.
Regards,
Apoorv

So, getting the watch to work is going to involve editing the build.prop file. You will need a file editor(like Total Commander) and superuser permissions(Root). Edit all mentions of "LG" To "HTC".
You will also need to install the apps needed to support the watch via apks.
