Samsung A13 vibrates, doesnt connect to PC and doesnt work when trying force restart

[Guus A]

my phone is acting very weird, screen doesnt function but seems to vibrate when touching certain parts (only if i press power button first). When I try connecting to pc it doesn't work and when I try force restarting it with volume down and power button it just buzzes twice then still does nothing

When I hold volume down and power button it vibrates twice, 1st one after exactly 12 seconds and second one after exactly 15 seconds. then a 9 second break before it repeats.

@Guus A try 

Clear Cache Files from the phone's System Partition Section  > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop or use a Tv's USB Port or a usb-c to usb-c phone to phone set up to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too { Possibly excluding the s²⁴ Series of phone's } 

And or Try a forced reboot by holding down the volume down key and power button simultaneously for more than 7 seconds to restart it. When your phone resets, you will feel it vibrate.

If i can be of any further help please don't hesitate to ask  😎
