Is there any possibility to install in xperia M5 the xperia camera app containing exposure time?

[Matcor]

Hello,

I own a xperia M5, an xperia X, and an xperia XA1. X and XA1 both have an interesting feature in the manual mode of the camera app that allows for the selection of exposure time.

I understand that M5 has been abandoned by sony, but I wonder if there is any possibility to get this feature.

Thanks,

Matteo
