This trick worked for me everytime my phone bugs out or just stutters too often. I reboot the system and don't touch it for a good 5 minutes. After that everything should be running smoothly again
Hi Rawhide1111953 and welcome to the Community!
"Reboot" means the same as the term "restart", so it would involve turning your phone off and then back on again.
When I charge my phone and it finish fully charging I always restart it before using.
