We are sorry to hear about your Samsung Galaxy A52s 5G experience having issues because the airplane mode got stuck and you couldn't receive any signal or mobile data without turning it off.
Since your device got wet, I highly recommend bringing it immediately to the nearest Samsung Authorized Service Center in your area. Not only will it undergo assessment, but it will also avoid further damage or deterioration brought about by internal breakdown of components due to moisture left inside and rust buildup.
Check 2. Remove moisture.
After turning off your device, quickly dry off your phone. Remove as much moisture as possible from the battery, USIM, memory card, etc. using a dry towel or a clean cloth. Be especially thorough when drying areas where water can enter, such as the earphone jack or charging port. Use a cotton bud to ensure complete moisture removal.
Check 3. Remove foreign debris, if there's any.
If liquids such as drinks, seawater, or chlorinated pool water, etc. get in your device, it is extremely important to remove the salinity or impurities as soon as possible. This is because the foreign debris may speed up the corrosion of the mainboard. After turning off your device, take out any removable parts, soak in clean water for approximately 1~3 minutes, then rinse. Afterwards, follow Check 2 and thoroughly dry your device.
Check 4. Air dry.
After removing the moisture or impurities, leave your device to dry in a well-ventilated area or in the shade with cool air (from a fan). Air drying is recommended for devices that are waterlogged. Please note that attempting to rapidly dry your device using a hair dryer or hot air may damage your device. Moisture may be present in your device even after a period of drying, so it is best not to power on your device until you visit a service center to have it checked. After air drying, please bring your waterlogged device to a Samsung Authorized Service Center as soon as possible.
Check 5. Check the waterproof rating.
Most Galaxy models are dust and water resistance and feature the highest rating of IP68. Although the highest ratings support up to 30 minutes of water resistance at a depth of 1.5m, it should not be used in deeper areas or areas with high pressure. Your device may become waterlogged if it is at a depth of 1.5m for longer than 30 minutes.
- Dust and water resistance support may differ based on the device model, so be sure to check the device’s User Manual.
- An IP (Identification code for Protection) rating refers to the protection code of solids and liquids, and is a grade established by the International Electrotechnical Commission (IEC) regarding the durability of electronic devices against external impact and foreign debris. The first digit represents the dustproof grade (0~6) and the second digit represents the waterproof grade (0~8). In general, a waterproof rating of 4 or higher is classified as water-resistant.
- Device screenshots and menus may vary depending on the device model and software version.
