When I placed a sign and typed in "i", in the middle of a sentence, it automatically made it capital. I could not get it lowercase.
What I expected to happen was...:
It should have made the "i" lowercase since it was in the middle of a sentence.
What actually happened was...:
It made the "i" capital.
Steps to Reproduce:
1. Place a sign down.
2. Type a sentence with an "i" in it.
3. The bug will take place and the "i" will be capital.
What device and Android version are you running? Signs seem to have strange bugs that differ from one device to another...
