On my friends volt with the cm13 4/25 build his download manager doesn't really work, any ideas why? Whenever he tries using it (from play store or anything else like xposed installer) it doesn't start the download -until he restarts. Meaning he will press download, it will say downloading but not go, and after he restarts the phone the download from before will start and finish fine. This has been happening since he flashed this months ago. He already tried clearing the app data. Now what?
