Hi,
If your screen works but not the touch facility try this.
Buy an OTG (on the go) cable suitable for your phone. This will enable you to connect a mouse so that you can navigate thru your phone, as you need to alter some settings before you can connect your phone to a PC
Download a program to your PC called Coolmuster Motorola Data Recovery, Install the program then connect your phone to the PC and hopefully the program will allow to to download your texts
