I have a samsung J5, I really am not very technical, but after what appears to be a recent update - when I go to use my phone, I usually swipe the screen, which usually leads to the screen where I enter my pin..........
Now when I swipe the screen, it just leads me to a black screen....but if I keep pressing all of the buttons - home button, back button etc in no particular order I can mostly get to the pin screen, but it's driving me mad!!
I have had a look around on the internet, I have turned the phone off, I have taken the battery out of it, I haven't downloaded any new apps recently.
Can anyone help me please.
