Reproduction steps:
# Open the user’s attached project (“TextInput.zip”)
# Build and run on an Android device
# In the XXXX InputField enter “abcdefg”. At the end of this step, the string will read "abcd-efg"
# Place caret between "-" and "e" and hit backspace once. The string will change to "abce-fg" and the caret will be at the end

Expected result: Caret will be placed between "c" and "e"
Actual result: Caret will be at the end

Notes:
* Within the editor, this script works as desired. On an Android build, however, the caret will jump back to the end of the line if a modification was made to the caret position.

* The desired behavior is the one in the Editor, the android build should replicate this!
* Watch “Repro.mp4” video for reproduction steps
