Like in my previous post, I explained I made some workaround for iOS, which is about the keyboard overlapping the native field. This workaround includes separate screen with only one native field (in the upper side of the screen). When the user finishes entering the text, I show the form page (which was hidden by the single-field screen for the time entering the text).

So, on samsung galaxy tab the form page sometimes won't return to normal. (It will stay one keyboard higher than usual). And it will crash after this.
When opening the keyboard on the single-field screen, the native field won't move, but the other objects (one text field and another button for going back to the form page) will go up and be above the visible area of the screen.

On Htc desire I don't experience screen position problems. But when I'm going back to the form (which includes hiding the single-field screen, hiding the keyboard and showing the form page again) sometimes the app just plain closes.

PLEASE GIVE SOME FEEDBACK ABOUT THIS. I want to know if Corona is FAMILIAR WITH THESE ISSUES, whether or not this is worked on, and if it will be fixed in the following week (or two). Or if I'm doing something wrong! This really is bringing my confidence in the product down.

Here's my single-field screen source:

bg_ = nil
field = nil
nameLabel = nil
doneButton = nil
callback = nil

function closeScreen()
native.setKeyboardFocus( nil )

bg_:removeSelf()
if field then
field:removeSelf()
end
nameLabel:removeSelf()
doneButton:removeSelf()

--callback("fdsfsafsdfdsf")
callback(field.text)
end

function endFieldEditBtn( event )
if ( event.phase == "ended" ) then
closeScreen()
end
return true
end

function endFieldEdit( event )
-- Hide keyboard when the user clicks "Return" in this field
if (event and event.phase) then
if ( "submitted" == event.phase or "ended" == event.phase ) then
closeScreen()
return true
end
end
end

function bgNoMethod()
return true
end

function startFieldEdit(text, name, callback_, inputType)
print ("start field edit: " .. name )
bg_ = display.newRect(0, 0, display.stageWidth, display.stageHeight)
bg_:setFillColor(20, 60, 18)
bg_:toFront()
bg_:addEventListener("touch", bgNoMethod)

nameLabel = display.newText( "", 200, 50, "Helvetica", 22 )
nameLabel.text = name
nameLabel:setTextColor( 255, 255, 255, 255 )
nameLabel:toFront()

local fH = 38
if (PLATFORM_ID == 2) then
fH = 50
end
field = native.newTextField( 100, 130, 200, fH, endFieldEdit)
field.text = text
if (inputType) then
field.inputType = inputType
end
--native.setKeyboardFocus( field )

doneButton = display.newImageRect('back.png',75,15)
--display.newRect( 150, 130, 100, 40)
doneButton.x = display.stageWidth/2
doneButton.y = 220
doneButton:addEventListener("touch", endFieldEditBtn)
doneButton:toFront()

callback = callback_
end

Here is the log (I've replaced my client's name with dots):

UPDATE: I think that the crashing is caused by this:

native.setKeyboardFocus( nil )
