[T-Mobile Samsung Galaxy Note 3] kirkers:
After this notification all my app updates fail to install!

I'm seeing the same thing, but not just once. For the past couple of weeks (since mid-October or so) this is happening every time I run Play Store update (which I have set not to occur automatically, but it makes no difference even when I change it back).

More importantly, once external storage reports it is in the range of 1 MB or so, every app thereafter dutifully downloads and then fails to install with error message: "Couldn't install on USB storage or SD card". Both "USB storage" (internal to phone but treated like a USB device) and SD card are multi-GB, and there is plenty of room. Still, no installation! :crying:

As I said, I have never saw this happen before the last couple of weeks.

Based on the limited info thus far on this little thread here, I'm not so sure it is my device or apps at all. Still, I will share what I did prior to finding this thread in the hope that it will help others and perhaps give clues to a skilled dev out there. :fingers-crossed:

At first, I thought it was something about my particular device/setup, which I find is almost always the case. Here are my basic particulars:

Droid Incredible "dinc", rooted, security OFF, with Tiny's mod of CM 10.1 (Jelly Bean 4.2.2), plus Tiny's ext4all patch to expand internal memory space to about 748MB.

My internal memory is getting a bit low despite moving most apps to SD card but it is still respectable:

"settings-->apps-->all" reports 200MB "internal storage" free, while Titanium Backup Pro summary for "internal" reports 249MB free.

(Can't quite figure why there is a difference in the numbers, but in this case it shouldn't matter.) :confused:

The only other significant recent additions of apps is that I purchased and installed the full version of "Air Control" game on 29 Sept. and purchased a 1-yr sub for Avast Mobile Security (AMS) on 3 Sept. The problem came about some time later, but Air Control's apparently forced presence in internal storage (see workaround #2 below) and AMS's involvement in scanning every app installation may be contributing factor(s).

As far as I can determine from Avast support resources, AMS scanning cannot be turned off temporarily and would have to be fully uninstalled, which is also not very easy on a rooted phone. So I have thus far left that stone unturned!

Maybe this bug is caused by Google Play Store client app or the Google online system? I followed the troubleshooting steps on the "known issues" Google Play Store page -- click on "Contact Us" to launch the troubleshooter and select "Download Unsuccessful":

Google Play Store support page

1. Clearing Google Play and Download Manager data caches alone made no difference.

2. Doing #1 AND rebooting my device did allow successful "update all" multiple installations.

3. Remounting SD Card was suggested, but I have not tried that option as yet. Maybe it would help?

Prior to tweaking the Play Store app (which may be all that is really needed), I found a couple of other workarounds that at least allow me to update my apps with a minimum of fuss -- no rebooting or labourious individual cache clearing required! Maybe these will help others, too:

1. Installed AVG Cleaner app that makes it easy to clear cache from download history + app caches in one swoop. It seemed to make a difference with some but not all of the smaller apps (<5MB), but no go with larger apps like Twitter and Chrome (>5MB). Not absolutely certain this tweak is really doing anything to help out this situation.

2. Uninstalled the game "Air Control" paid version that stubbornly refuses to be moved to SD Card. Titanium Backup Pro (TBP) says it moves it, but in fact it does not. At least some large chunk of it remains in internal storage. Once I uninstalled Air Control using TBP, I was able to install all updates, BUT ONLY MANUALLY (i.e. one at a time) in Play Store. Auto-updating and "update all" in Play Store continued to fail, whether the low external storage warning appeared or not.

3. I searched the web to see what fixes I could find, and came up with a recommendation for Lucky Patcher (LP), which reportedly can remove all traces of a misbehaving app through its "Troubleshooting" process.

Here is where I found this recommendation (see under "Option 1"):

How-to-fix-insufficient-storage-available-error-on-android-phones

I am now aware that LP is warez and does some pretty nasty things to crack security on apps (definitely not what I want to do -- I pay developers when they ask for it and am happy to support them!). :angel: I just wonder if LP's less nasty function of app cleaning would resolve this current issue. I actually haven't tried using LP yet in any respect.

Better yet, is there some other less potentially destructive app than LP or some other tweak/procedure that will fix this bug/issue?

As I said earlier, I have not taken the step of uninstalling Avast Mobile Security since it is so involved on a rooted Android.

Hoping there is a skilled dev or two out there who can tackle this one, or at least evaluate the workarounds and tweaks listed here. :fingers-crossed:
