My phone while I've been using it bad completely soft locked 4 times so far this month I'm beginning to be concerned, this last one I was listening to music and scrolling through a shopping app and the music stops and phone completely freezes, it's madness

My suggestion is to try these generic troubleshooting steps @williamg209 

Do please check your apps and phone's software is up to date and no apk files are being used. 

Sometimes downloaded themes or battery monitor apps can cause glitches too. 

• Safe Mode  > https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/ turns off downloaded apps and themes etc which may highlight an app or theme that's causing conflict. 
• Clear Cache Files from the phone's System Partition Section  > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop or use a Tv's USB Port to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too. 
• Back up and factory reset.
