Solution 2: Close Background Apps

Other apps running in the background can use memory and cause freezing.

  1. Swipe up from the bottom and pause in the middle of the screen
  2. You'll see all open apps
  3. Swipe up on each app to close them
  4. Open only CENTR

Android:

  1. Tap the Recent Apps button (square icon or swipe up and hold)
  2. Swipe away all apps except CENTR
  3. Or tap "Close All" if available

Solution 3: Check Device Storage

Low storage space causes apps to freeze and run slowly.

iPhone:

  1. Go to Settings
  2. Tap "General"
  3. Tap "iPhone Storage"
  4. Check available space - you need at least 500MB free
  5. Delete unused apps, photos, or videos if space is low

Android:

  1. Go to Settings
  2. Tap "Storage"
  3. Check available space - you need at least 500MB free
  4. Tap "Free up space" to clear cached files
  5. Delete unused apps, photos, or videos if space is low

Solution 4: Restart Your Device

Restarting clears memory and stops all background processes.

  1. Power off your device completely
  2. Wait 10 seconds
  3. Power back on
  4. Open only the CENTR app (don't open other apps first)

Solution 5: Update the App

Freezing bugs are often fixed in newer app versions.

iPhone:

  1. Open the App Store
  2. Tap your profile icon
  3. Scroll down to see pending updates
  4. If CENTR has an update, tap "Update"

Android:

  1. Open Google Play Store
  2. Tap your profile icon
  3. Select "Manage apps & device"

Solution 6: Clear App Cache (Android Only)

Clearing cache removes temporary files that may cause freezing.

  1. Go to Settings
  2. Tap "Apps" or "Applications"
  3. Find and tap "CENTR"
  4. Tap "Storage"
  5. Tap "Clear Cache" (NOT "Clear Data")
  6. Open CENTR again

Note: iOS doesn't have a cache clearing option. Skip to Solution 7 if you're on iPhone.
