3. Avoid DIY Water TestingYou can be tempted to dip your phone in water to test it. Don’t! It’s a risk, as DIYs can ultimately end up badly, causing a lot of water to enter inside
the phone and damaging its internal parts. Hence, rely more on visual inspections.
4. Check for Water-Detection IndicatorsJust open the SIM tray and inspect the insides. There’s a small white sticker that might have turned red or pink. If that’s the case, your phone was exposed to water, so that water resistance may have
already been compromised.5. Use a Waterproof Case for Added ProtectionIf you are seriously worried about water damage, add a waterproof case as an extra layer of protection. Case rated
IP68 or higher are tailored to provide extra security, even if the phone’s original water resistance feature deteriorated.
