I have an LG G2 with Android 4.4.2, and all. All of a sudden I cannot download apps or updates on the Google Play store: no error messages, it just spins its wheels. On the Google Play Store, it just says "Downloading..." with the loading bar running infinitely, and in my phone drop-down screen, the same thing. No progress bar, completion %, est. time, anything.
In my settings > mobile dataSettings › Mobile data menu, the "limit mobile data usage" option is NOT checked, and the problem persists on both 3G and 4G/LTE. My data limit has not been reached (I don't even think I have one).
In the settings > mobile data > google play storeSettings › Mobile data › Google Play Store menu, the "restrict background data" option is NOT checked either. In the Google PlayGoogle Play app settings menu, the "Auto-update apps" is set to wifi-only, but that's how I want it. The problem is when I manually try to download/update, so that shouldn't be the problem.
My Google Play build version is 5.4.12, if that helps...
Wi-fi downloads are just peachy though.
Just checked my network signal strength and it's -116 dBm and 26 asu, whatever those mean.
