Decide Whether It Is the App or the Phone
First, compare. If every app crawls and the phone itself lags between screens, the handbook is a witness, not a culprit, and the fix will be device level. If only this app is slow while others fly, focus on its cache, its version and its connection. This one observation halves the troubleshooting work instantly.
The checklist in this section is deliberately practical, because fixing slow performance improves fastest when a few basics are repeated until they become automatic. Work through the points in order, notice which ones you already do without thinking, and give the others a full session of attention before moving on. Small, repeatable habits are what separate players who improve every week from players who repeat the same first week for a year.
ICPV Book key points on this step:
- Compare with other apps
- Device wide slowness is a phone issue
- App only slowness narrows the field
- Note when the slowness began
- Test the same items each time
