LCD Not Working

Long story short, it's display got cracked, but the LCD panel is completely ok but 'Touch' does not work, so I decided to use a mouse to use a tablet, I connected a USB mouse using a Micro USB converter, the mouse turns on but it's curser does not show on the display and it does not work. I can't get past the lockscreen. What can I do? What Should I do? Why does the mouse does not work?
p.s. Repairing is not a option right now.
Found any solution?

i9505 - issues with smart dock after lollipop upgrade

Hi all. I've looked for an answer to this issue, but to no avail.
I usually dock my s4 to samsung' s smart dock at home and I use it connected to a tv with mouse and keyboard attached for basic needs. Till lollipop upgrade everything worked flawlessy, now there are some issues:
Original TW: upon connection (power, hdmi etc), the screen goes off and appears on the tv, oriented and scaled to fill the display. this is fairly good, since I don't need anymore a rotation control app, the problem is that if the screen goes off, the only way to interact with the phone is via keyboard and mouse, which is annoying. does anyone know a way to control this behaviour?
GPE: the screen stays on upon connection, but sound is not sent through hdmi, only through the smart dock 3.5mm connectior
thanks, any hint appreciated

Samsun dex

Hello to all,
I have a puzzle for you.
I have an S8 but I don't have a touch screen anymore.
I would like to launch samsung dex but it asks me to press continue on the screen.
I have a S8 but I don't have a touchscreen anymore, would you have any idea how to switch to samsung dex?
I would like to use what I have left of my S8 as a multimedia player.
Thank you.

You can buy a USB-A to USB-C adapter (or OTG) and plug in a mouse.

of course this is what I use, but it requires me to validate by clicking on the touch screen which I no longer have

Touch Screen won't work not even with mouse

Hi!
I've recently bought a car that coincidently has a Android Head Unit (right now I don't have any specific version other than it looks a lot like the generic ones that have the touch buttons on the side) and it also has AGAMA car launcher, but the problem is that we can't get to click anything! I know/think the touchscreen is not the problem because when I try to do a calibration it does go to the 4 dots screen, but I'm not able to click on them. I've also tried using a keyboard/mouse combo but it does show up the cursor, but apart from that no click either, I also tested the volume and home/back button and they seem to work.
I've tried almost everything they had on youtube, and I've also disconnected the battery just in case but with no luck, does anyone know what could it be
Thanks!
