My primary issue has been trying to use the calling functionality of the phone (SAMSUNG INFUSE 4G). Phone got wet & was powered up at the time. I was not able to dry it out properly until a few hours after was exposed to the water. I did that as soon as I was able, for a couple days, then tried to power it back up. It came back on very slowly at first. It's much better now, virtually normal (as far as power up). Also, lost a lot of apps (that I think were stored on the external SD card). So, the main issue......
During incoming calls:
Call comes in --> I swipe the "Accept" icon, which moves across the screen, but freezes in place. I cannot hear the other party & they cannot hear me. After several seconds (maybe 30), the entire screen turns black, except for the status bar at the top of the screen.
After about 30 more secs, the call screen comes up, but by then the other party has disconnected.
About 5-10 secs later, the call screen quickly flashes "Call Ended" & immediately goes to the missed call log record & displays a pop up stating,
"Sorry! Activity Phone (in process com.android.phone) is not responding." FORCE CLOSE or WAIT
The speaker stills works, as I can hear video, or alarms.
I don't think the mic works, as I cannot be heard & the "Speak" function doesn't work for voice searches or texts & the like.
I also continually show a "Blank External SD Card" icon in my status bar, as long as I have it installed.
Have tried factory reset, but it still does the same thing.
Also, thoroughly cleaned the phone about a week after this happened. Took it apart & gently brushed away any deposits from dried liquid, cleaned with denatured alcohol & put back together. Same issues occurred, although not quite as bad (long delays) after the cleaning.
Sorry this is a book, but I figure providing as much detail as possible, will hopefully bring a quicker answer.

Thanks!
