frozen iPhone wont let me slide to unlock

"Did you try a hard reset by holding the power and home button together for 7 seconds, then let go of the home button and continue holding the power button? This will restart the iPhone.

Was it dropped prior to this?"

dismantle it and clean touch ic with ipa reheat with hot air station if not luck after replace logic board

If you dropped your phone or if you or someone else replaced the screen or something dealing with opening the phone, then the screen might be messed up (LCD & touch screen). Replacing the screen should be a final solution after trying the other solutions mentioned above by others.

What you have to do is hold the sleep and home button for ten seconds and let go of the Home button but still keep holding the sleep button and your Phone should restart and when it does it goes a bit Black but just wait and it will be back to normal

Try this guide. It worked for me https://www.youtube.com/watch?v=uit5IFu8...

"Maybe caused by ""Not enough storage"", as i have experienced.

Go to Setting to check if you have enough storage, and if not delete something to get more storage."
