My phone: LG Tribute Monarch. Relatable to LG phones without SD CARDS such as mine. This is not a PANDORA issue at all. From my experience on 3 different music apps as well as this one, has been more of a storage/low memory issue versus a power restriction issue. I've dealt with this issue for months, since the purchase of my device. I've done all of the same troubleshooting and it still happens. The music will stop, on occasion, when I've received notifications such as text messages or massages from other apps like using my browser or search bar and other apps. This is not a PANDORA issue at all. Best advice, be diligent about clearing your caches, saving files that you want to keep in a cloud and deleting them off of your devices memory. Seriously, keep your gallery empty if you've already used what you needed then save and delete. This is just the factor and solution that seems to work for me. But do your phone backup and save it in Drive or another cloud first if you ever decide to HARD RESET your device, save your vids and pics in Photos or another cloud. Uninstall unused and seldom used apps. If this doesn't seem to help then Idk but wish you the best of luck. But there is no reason for you to reset your device. Just lower the amount of storage being used.  I've gone through all troubleshooting and the issue has best worked with clear storage.  ... View more
