Being on a plane, having your phone in the bathroom while a hot shower runs or just being in a humid country can cause the lens of your phone camera to accumulate condensation. Worse still, the main screen of your phone or iPhone can also steam up. You must take steps to remedy this problem, but you do not need to pay anyone to sort it out.
Cut open the bag of rice at the top. The bag does not need to be big, just bigger than the phone.
Plunge the phone into the bag of rice and then place another plastic bag over the top of the rice bag. Cover the rice bag so it is entirely within the plastic bag and then twist the plastic bag closed at the other end.
Leave the bag in a warm place for three hours. Open the plastic bag and then remove the phone from the bag of rice. Tap one corner of the phone on the table to shake out any grains of rice stuck in any of the slots in the phone. Your camera lens condensation will have been removed.
