why can't I download apps with 29 gigabytes of free memory on sd card I have 29 gigabytes of free storage on my sd card yet when I try to download more apps I get the insufficient storage message. All apps that I am able to move to sd card are. No matter how many apps I download the amount of free storage on sd card remains at 29 gigabytes.
Your android device has internal and in your case external storage. The external storage is, in this case, your SD card with 29GB of free memory.However most of the android apps get installed on your internal storage. You can check if your internal storage is filled up by going into "Settings -> Storage" and looking at the internal storage. If it is filled up try to move apps to your sd card by going to "Settings -> Apps -> Manage Apps" and you will see a list of installed applications. Click them one by one and in the menu you'll see an option "Move to SD Card" for some of the applications. You can alternatively root your device (or update to android V6.0+) and move all of your apps to your SD card using an app on the Google Play Store called AppMGR III.
