I learned that this can only be with by replacing it with a new one. Battery latch is a tiny piece of plastic lock that when you break it, you really need t replace it.

Try to update the software, if available. Cheers.

Maybe it’s a battery problem. You might want to check it if it can still supply the power needed. If not, you may consider replacing the battery? Cheers.

Try to removing and putting the battery back.

Burrying the phone on a bowl or box of rice will help sip the moisture, but this takes about “a week” before you should turn on the cellphone or any gadget. Allowing time to let the moisture out and have it dried completely will save your gadget from short circuit. I’m afraid yours has already been damaged, and best to replace the LCD.

You may need to replace the LCD. Cheers.

Check the Freon, maybe it is just out of Freon and you need to add, if your refrigerator uses this and if it is legal to use in your country. Cheers.

Try to replace it wit the same battery specifications first to check if it's no short circuited. If you have stores nearby that you can atleast try to have the battery installed if it is the right one, that would be good. If not, you can order online. this is to isolate the problem, if it’s the battery—replace it (cheaper), or sad if it’s the phone that has been damaged. Anyhow, you can try it. Cheers

Have you tried to vacuum the holes? It might help. Cheers.
