The following actions should not be done during Wudu (ablution):

• Talking on the phone while performing Wudu
• Checking messages
• Engaging in any other worldly affairs
• Cleaning the basin, handling tissues, or gesturing in the mirror during Wudu

Remember, Wudu is the key to Ibadah (worship). If the key is not right, the door will not open. Therefore, give importance to Wudu and perform it beautifully—InshaAllah (if Allah wills), all your Ibadah will achieve completeness.
