BSI and text messaging

Braille on Apple Products

Hello all,
I am encountering an issue with BSI and text messaing. When I turn the rodar to BSI and place my phone in screen away mode it is very difficult to get the finger presses to register. It usually takes me several times flipping my phone from screen away mode to tabletop mode and back again before I can get it to register finger presses. This happens every time I try to use BSI to write a text message. Has anyone else seen this before and if so is there a way to improve this behavior? I am using an iPhone 6 plus using the latest version of iOS. Also this only seems to be a big issue when in the messages app. It does not seem to happen as badly in other apps.
