Offline mode is an indicator of water damage or moisture damage. This is considered physical damage to the phone, and one would have to pay the deductible if you had insurance in order to get a replacement. If you don't have insurance, check for upgrade eligibility.

Try removing your battery for two minutes, and then putting it back in. Also try charging it with the phone off or in charge mode over night and test it again.

Try a hard reset. If this doesnt work, take your phone into the repair center.

Hi, once these are dropped in water or soaked, they,re in the Bin.
All you can do is This.
1:) remove the Battery.
2:) put the phone ( without as much casing as possible ) on A central-heating Radiator. On top of a towel.
3:) gently blow with a warm-hot set hair Dryer.
4:) replace Battery and switch on.
If non of this works, bin the phone, and give your son a clip around the ear :)
