Q: I cannot slide to unlock my iphone or slide to power off - the touch screen is not working - I downloaded ios7 about two hours ago.....

I get the same problem once in a while.

I have found two ways to unlock my iPhone:

make a call from another phone to yours, then it works. If it doesn't then switch OFF and back ON.

First thing to try is to reset your device. Press and hold the Home and Sleep buttons simultaneously until the Apple logo appears. Let go of the buttons and let the device restart. See if that fixes your problem.

this would give me a temparary solution but cant able to detect the cause of which the slide to answer is not working

Back up and restore via iTunes. If the problem continues, restore as a new device and test. If the problem is solved, there is some kind of corruption in your backup file or maybe it's one of your apps causing problems. If it continues, take it to an Apple Store for evaluation of a possible hardware problem.

my iPhone 4s screen does not work and i cant access it, and my power button does not work.please help me thanks to does.

So if you have an iPhone 4s, do you not mean that you upgraded to iOS 8 or 8.0.2, because anything else you cannot do and if you upgrade, you can only do so to the latest software and nothing else.

So what is it that you actually did and what software do you have installed on your phone?  Perhaps this is why you are having problems.

No....he means iOS7.  It was a year ago......

I know this problem is for a different device, but check this out, since the problem seems to be the same:

I have a iPod touch 3rd gen.  The screen slide was stuck in the lock position.  Over the course of the past three months I have tried the following with no success:

1.) Reboot (holding the power and home button simultaneously)

2.) Restore (both types--yes, I did the hard, factory reset) SEVERAL times.

3.) I pushed on the screen in every corner, sometimes very hard.

4.) I tried giving several voice control commands.

Everything I read on line (I've spent several hours researching), said the only thing I could do was bring it in to the Apple Store Genius Bar--they priced the labor at about $150!  For which I could buy a new one.  Then I remembered something CRAZY I had read a while back--I wasn't even sure I remember the correct order or even the explanation.  All I know is that it WORKED!  This is what I did.

a.) I put the iPod in a ziplock bag and pushed all the excess air out before sealing it.

b.) I put it in the freezer over night!  (Crazy, right?)

c.) Then about 24 hours later, I took it out--it was frozen solid--and tried to power it up.  No luck.

d.) I immediately put it under the hair dryer on high heat, high air.  About 20-30 seconds from, then the same for the back. 

e.) I tried to power it up; the Apple icon appeared!

f.) While it was powering up, I kept the air on it, rotating front and back--It got hot.  (I stopped after 1 minute.)

g.) When the home, configure screen reappeared, I was able to slide the slick, and re-configure!

h.) I've restored a previous back-up off my iTunes account, and the iPod is working again.  Resurrected!

If memory serves, the explanation I read is that many of the apply devices have an internal shutdown switch before they fry or freeze in extreme temps.  My guess is that the shutdown forces and internal reboot.  All I know is that after trying EVERYTHING ELSE--this method worked.  I did this on 18 October 2014.

i did the same thing u did to your ipod 3rd generation but only the top part of my screen works not the bottom part. what should i do to fix that?

You rock Ralph!  Could not slide the bar to unlock my phone today.  Went to the Apple store and they turned me away saying they had no appointment time slots available.  Found your post and was able to reboot and fix the issue!

Thank you!

Thanks Ralph, this method is legit. After searching the internet, and couldn't find a fix, I got another phone. Only to try out Ralph's steps and it worked.

Yippie. Try out his fix before buying a new phone...

THIS WORKS!! I only left it in the freezer for a few hours and it did the trick.

Wow! It works. Thank you so much

I am having the same problem but my power button is not working
