I have an iphone 5 (A1429) running iOS 7 beta 3, beforehand was running beta 2 aswell, without being a developer / having a verified UDID.

Beta 2 gave me no problems whatsoever however after a few days of running beta 3, I woke up this morning and my phone was working fine, left it for a while and now when I go back to it, the screen is completely back and isn't responding to anything I do. I know the phone is on however as I asked my mum to phone me and she said it is ringing. I've tried plugging in the charger, nothing. Connecting to iTunes, still nothing (iTunes also doesn't notice it has an iPhone connected).

Right now I'm going to wait for my phone to completely drain of battery in hope that when I start to charge it afterwards it'll come alive, until then there isn't much more I can do. I'm not sure if this is a hardware fault or a software fault but I never had any problems up until beta 3. Just a heads up guys.

did you try a hard reset? i had the same problem in beta 2 and that fixed it for me

I did indeed try a hard reset, nothing responded and I had to allow the battery to drain. Thankfully there wasn't much battery. I've restored to 6.1.4 right now and everything appears to be fine, thinking of going to the Apple Store to get an appointment with the Genius Bar however incase it is hardware related.

I had the same problem but I just held the home button and power button until the apple logo appeared, then let go of them both and it worked fine. It's done it twice on beta 3 now..

My friend is having the same problem on his Iphone 4, when it goes black he just holds the power and home button together and it comes back on. I have a Iphone 5 and I have had no problem yet.

Same thing happened to me and my power button is broken, so I had to wait a full 24 hours and plugged it in and it finally came on..i downgraded back to iOS6 .1.4 and sending iPhone 5 back to apple to get the buton fixed

Try putting it in dfu mode and then restore it

I have it sorted thank you, going from what I've seen here and searched on some Apple fanboy forums, it is definitely the operating system and not the iDevice.

Ok that's good and good luck with the other beta's

I've had a similar problem with beta 3, from just locking the phone it froze up the screen. Though a hard reset fixes the problem 10/10 times i'm used to it being a little buggy hence my previously jailbroken iPhone was running an excessive amount of visual effect tweaks and was desperately in need of space (literally 0mb available,). Beta 4 is supposed to be the "polished".
