Here are some things you can do if your Tecno phone falls into the water: Remove the phone from the water as quickly as possible: The longer the phone is in the water, the more damage it will suffer. Turn off the phone.  Do not try to turn it on again until it has been thoroughly dried. Remove the SIM card, memory card, and battery. This will help to prevent water damage to these components. Dry the phone with a clean, soft cloth. You can also use a hair dryer in a cool setting to help speed up the drying process. If you follow these steps, you may be able to save your Tecno phone from water damage. However, if the phone is not working after you have dried it out, you may need to take it to a repair technician.
