Step 4: Note down the static IP address fields and wipe off all the fields. Punch it in again and then save it.

Below are some possible causes of Vivo S18 Pro screen unresponsiveness, along with explanations of each.

  • Soft-bricked software: Soft-bricking refers to the state where the phone is stuck in an infinite boot loop or unable to boot. It can occur due to corrupt system files, outdated firmware, or unsuccessful updates.

These issues can also occur in any Vivo S18 Pro model, including the Y2 and 5A.

  • **Touchscreen problems:**Sometimes, the touchscreen itself can become unresponsive for various reasons. For instance, Vivo S18 Pro Y2 and 5A users may face this issue if they have accidentally dropped their phone, exposed it to water, or used an incompatible screen protector. It can result in a damaged or malfunctioning touchscreen, making it difficult or impossible to operate the phone.
