Using a blow dryer to dry a wet phone is not recommended. While it might seem like a quick and convenient solution, it can actually do more harm than good. Blow dryers produce hot air, which can potentially damage the delicate internal components of the phone, especially if the heat is too high or focused on a specific area for too long.
When a phone gets wet, the best course of action is to turn it off immediately and remove it from the water source, if applicable. Then, gently dry the external surfaces with a soft cloth or towel. Next, you should place the phone in a desiccant or absorbent material, such as uncooked rice or silica gel packets. These materials can help absorb the moisture over time.
It's important to leave the phone in the desiccant for at least 24-48 hours to allow the moisture to be fully absorbed. Avoid turning on the phone or attempting to charge it during this time. Additionally, you can keep the phone in a well-ventilated area to aid in the drying process.
If after this drying period the phone still doesn't work, it's recommended to take it to a professional technician or contact the manufacturer's support for further assistance. They may be able to help assess the damage and suggest possible repair options.
