Hi, You need to connect the controller to the PS4 first with a micro USB cable, then press the PS button. (You didnt say whether you were using a cable or not) If that doesnt work then try a different cable: I sometimes find that not all cables work for some reason even if they charge the controller. Hope this helps, That Tech Enthusiast

Hello, No you can’t, as HDMI and mini HDMI are for display and sound output only. I would try and find a replacement USB port and repair it, or take it in to a repair shop. I hope this helps.

Hello, No you will not be able to do this. First of all they are both different sizes which therefore means that lots of connectors will be in the wrong places. Below I have linked a replacement guide as well as a link to the iFixit store where you can buy a replacement logic board if you need one. iPhone 6 Logic Board iPhone 6 Logic Board ersetzen Hope this helps

Hello, By the sounds of it, the only part of the phone that’s damaged seems to be the screen so below I have linked the guide and replacement screen for the pixel 3a. The guide will tell you the tools you will need. You can buy them all desperately or you can buy the Essential Electronic tool kit, which includes everything you need. (Apart from the iOpener but I tend to find using a hairdryer to blast some heat onto it seems to work nicely as well if you don’t want to spend the extra money to buy one.

Try un-installing any pre installed software that you don’t need. I had this problem a while a go and sometimes factory resetting it helps (Make sure you have everything backed up). You could also try upgrading the RAM or replace the HDD with an SSD. I have upgraded the RAM on a few laptops and they all seem pretty easy to do.
