To be honest Ray2jen1 it sounds like your device is running low on ram, try going in to your widget and look for Active apps. this will let you know what is running in the background. and help reduce you ram from being sucked away, I have seen Chrome by its self use over 400MB combine that with facebook which can use up about 150-200 MBs it does not take much to eat up the remaining amount. Also make sure your apps are fully up to date. there are a lot that you have to accept T&C in order for them to up date. if all else falls try running the Software Update Repair Assistant. just plug your phone in to your pc with the File Explorer Window Open and you will see a CD option pop up that says Verizon Mobile just click download install and let run, it will also allow you to back up your data to your pc, but only while it does the restore. then it puts it back on the phone, then deletes it form the pc.------ but be warned you will have to set your phone back up. oh do make sure to disable auto restore in the backup and reset under settings other wise it will automatically restore all the apps in your google play account. if all else fails try www.samsung.com/us/kies but Verizon does not support the kies tool and falls out side the scope of tech-support. if you have any further questions I would be happy to answer them.
