iPhone 8S new 2018.
Ancient Iphone 8S has been having issues with running apps in the last few months. Apps that I use on a regular basis, will no longer function. Purchased the phone new in 2018. It's running iOS 16.7.16 and says it is current. My theory is that the phone is old enough that it can no longer keep up with the apps. Any suggestions? I love my phone and don't want to buy a new one.
