Hello chrispdx2k,
Thank you for reaching out to Apple Support Communities, and we'll be happy to help in any way we can. We understand you're having issues with scrolling on your iPhone. Try adjusting your touch settings as outlined here to see if it helps: Adjust how iPhone responds to your touch
"Adjust settings for taps, swipes, and multiple touches
- Go to Settings > Accessibility > Touch > Touch Accommodations, then turn on Touch Accommodations.
- You can configure iPhone to do any of the following:
- Respond to touches of a certain duration: Turn on Hold Duration, then tap or to adjust the duration. (The default is 0.10 seconds.)
- Prevent unintended swipe gestures: To increase the amount of movement required before a swipe gesture begins, tap Swipe Gestures, turn on Swipe Gestures, then adjust required movement.
- Treat multiple touches as a single touch: Turn on Ignore Repeat, then tap or to adjust the amount of time allowed between multiple touches.
- Respond to the first or last place you touch: Choose Use Initial Touch Location or Use Final Touch Location.
- If you choose Use Initial Touch Location, iPhone uses the location of your first tap—when you tap an app on the Home Screen, for example. If you choose Use Final Touch Location, iPhone registers the tap where you lift your finger. iPhone responds to a tap when you lift your finger within a certain period of time. Tap or to adjust the timing. Your device can respond to other gestures, such as a drag gesture, if you wait longer than the gesture delay.
Adjust settings for touch-and-hold gestures
The touch-and-hold gesture reveals content previews, actions, and contextual menus. If you have trouble performing this gesture, do the following:
- Go to Settings > Accessibility > Touch, then tap Haptic Touch or 3D & Haptic Touch.
- Choose the touch duration—Fast or Slow.
- On an iPhone with 3D Touch, you can also choose the pressure needed—Light, Medium, or Firm.
- Test the new setting on the image at the bottom of the screen.
Turn off Tap to Wake
On a supported iPhone model, you can prevent touches on the display from waking iPhone. Go to Settings > Accessibility > Touch, then turn off Tap to Wake.
Turn off Shake to Undo
If you tend to unintentionally shake iPhone, you can turn off Shake to Undo. Go to Settings > Accessibility > Touch.
Tip: To undo text edits, swipe left with three fingers."
We hope this helps.
Cheers!
