Scrolling stutters inside apps on iOS 27.2 (iPhone 17 Pro Max / 18 Pro Max) - anyone else? Any fix?

Scrolling stutters inside apps on iOS 27.2 (iPhone 17 Pro Max / 18 Pro Max) - anyone else? Any fix?


On my iPhone 17 Pro Max and iPhone 18 Pro Max (iOS 27.2), scrolling inside apps frequently stutters. During a normal flick, the content freezes for a split second and then jumps forward. It happens in Apple's own App Store app and in many third-party apps. I also see it on demo units in Apple Stores.




I measured it with 120 fps recordings: in the App Store app, about 5 hitches per second of scrolling. A system screen recording shows the same stutter, so it does not seem to be a display hardware issue.




I have already restarted, reset all settings, and reported it to Apple.




Is anyone else seeing this on iOS 27? Has anyone found anything that helps?

You may try some of these steps. Please check after each step...


  1. Having too many apps open may cause this issue, as RAM is being used by other apps, leaving less memory available for proper rendering. Close an app on your iPhone or iPod touch
  2. Overloaded system: Too many apps running in the background can cause stuttering. Refresh content in apps you're not actively using on ...
  3. Storage issues: Low or fragmented storage can slow down the camera. --> Manage and Clear Storage on your iPhone a… - Apple Community
  4. Sometimes, a simple restart can resolve temporary software glitches. Turn off your iPhone, wait for a few seconds, and then turn it back on.
    1. Restart the device. That's it.
    2. Still not solved --> Force restart iPhone - Apple Support
  5. If you're using a VPN, disable it and check if the error goes away. Go to Settings > General > VPN & Device Management and turn off any active VPNs. Disabling a VPN only from the iPhone settings may not completely turn it off. To fully disable it, you need to switch it off from the VPN service provider’s app or remove the configuration profile they installed. Only then is the VPN truly off, which can help if it’s causing issues with cellular or Wi-Fi connectivity.
  6. Reset Network Settings: Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings: Only network settings are removed.
    1. When you reset network settings, previously used networks and VPN settings that weren’t installed by a configuration profile or mobile device management (MDM) are removed. Wi-Fi is turned off and then back on, disconnecting you from any network you’re on. The Wi-Fi and Ask to Join Networks settings remain turned on.
    2. To remove VPN settings installed by a configuration profile, go to Settings > General > Profiles & Device Management, select the configuration profile, then tap Remove Profile. This also removes other settings and accounts provided by the profile. See Install or remove configuration profiles on iPhone in this guide.
    3. To remove network settings installed by MDM, go to Settings > General > Profiles & Device Management, select the management, then tap Remove Management. This also removes other settings and certificates provided by MDM. See “Mobile device management (MDM)” in the iOS Deployment Reference.
    4. Reset your Network Settings. Tap Settings > General > Reset > Reset Network Settings. This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you've used before.
  7. If the issue persists, you can try resetting all settings on your iPhone. This will not erase your data but will reset all personalized settings to their default values. Go to Settings > General > Transfer & Reset > Reset > Reset All Settings and confirm the action. Note that you will need to reconfigure your settings afterward. All settings—including network settings, the keyboard dictionary, the Home screen layout, location settings, privacy settings, and Apple Pay cards—are removed or reset to their defaults. No data or media are deleted.
    1. Reset All Settings: Return iPhone settings to their defaults - Apple Support:- Return iPhone settings to their defaults
    2. You can return settings to their defaults without erasing your content.
    3. If you want to save your settings, back up your iPhone before returning them to their defaults. For example, if you’re trying to solve a problem but returning settings to their defaults doesn’t help, you might want to restore your previous settings from a backup.
  8. Make sure you have the latest updates installed.
    1. Update Over-the-Air (OTA) —> Update your iPhone or iPad - Apple Support (IN)
    2. Update using iTunes/Finder —> Update your iPhone, iPad, or iPod touch - Apple Support (IN)


If none of the above steps resolve the issue, it is recommended to reach out to Apple Support or visit an authorized service center for further assistance. They can provide specific guidance based on your device model and iOS version.

Usual causes

  • lack of free space
  • use of VPN or adblock apps that are VPN based
  • poor connection speed (such as inside stores)

No! you can only have one app open at once on iPhone. Apps off screen are not using measurable amounts of RAM
