I'd like to give a big thankyou to you guys. ewpatton especially for the temp server. I have an SMS App i created so i could send out rosters to my staff at various Distribution Centres. You can understand how frustrated i was when i got a newer Samsung and that message of doom appeared. I could use the app on my older Samsung just fine but i wasn't going to keep carrying 2 phones around. I opened your temp sever and then i had to import my aia project into the new server and do a new APK build. I uploaded and it works like a treat now. Very, very happy, thank you 
So a couple years have passed on this issue, I just imported an aia file for an old Android project with serial and it still has this error. I am not that experienced with MITAI, is there now a simple solution to fix this Serial problem? Or should re-selecting the SerialOTG1 correct things? Any details greatly appreciated.
