7 You’ve probably heard the suggestion to put your phone in rice if it gets wet, but we do not recommend this
method. Instead, try silica gel packets, like the ones that often come with new products such as a pair of shoes,
as they’ve proven to be much more effective. Fill a plastic zip-top bag with silica gel packets and bury the
phone in the bag. Leave your phone in the bag for 24–48 hours.
8 After you’ve allowed your phone to fully dry, switch it on. If it doesn’t turn on right away, charge it fully and try
again.
If your phone turns back on, great! Still, keep an eye on it over the next week or so, as sometimes certain features
won’t work the way they used to.

If possible open the mobile phone separate their parts and leave it for 2 days and turn it ON.
