Delay in response from lock button

[Shrinidhi_Parla]

Hi,

Im using galaxy a55. After one UI 7 update there is a delay in pressing side button and screen turn on. Nearly 3 second delay.

Anyone facing this issue.

1. **Wipe Cache Partition (no data lost):**

Turn off the phone.

Hold Volume Up + Side button until the Samsung logo appears.

Navigate to “Wipe cache partition” → confirm → reboot .



2. **Reduce Animations or Switch Resolution:**

Go to Settings > About phone and tap Build number seven times to enable Developer options.

In Developer options, set Window/Transition/Animator scale to 0.5× or off.

Optionally, if available, change Resolution to QHD+ to see if it improves responsiveness .



3. **Check in Safe Mode:**

Hold power button → tap and hold Power off → choose Safe Mode.

Test the button wakeup. If it’s smoother in Safe Mode, a third‑party app might be contributing to the issue.



4. **File a Bug Report:**

Use the Samsung Members app (Support → Error reports) to submit logs. Samsung may prioritize a fix if more users report it .



5. Stay Updated:

Go to Settings > Software update and check for a new patch. Samsung is aware of this bug and a fix could arrive in an upcoming update.
