Ok, so I was drunk. I jumped into a pool with my Samsung Galaxy S3 (Tmobile) still in my pocket. I immediately shut if off, removed SIM, SD card and battery and immersed it in a bowl of rice for 24 hours. I re-installed everything and to my surprise it turned on and seemed to be working. However, in the following days I noticed that I'm registering 4G and Data, yet unable to make calls. Weird. This problem is intermittent because there are times I'm able to make calls on 4G. It works great on WiFi. I have already replaced the battery. This is becoming frustrating! Could it be a hardware problem? software? I just would like to take it to a repair shop and have them replace or concentrate on the area that has malfunctioned. Any ideas?
