My iphone 5 got submerged in the sea for about 2-5sec but now it's all functioning.All the water sensor are white. After 1-2 days my iphone got the searching loop. I've done reset and turn on/off several times then after that I got a signal from my carrier. After a week, my iphone got stuck in search loop until now, the reset things did'nt solve my problem anymore. Is this because of the water damage???
