I often do iPhone repairs but i have a question about an iPhone that is showing strange behaviour.

This iPhone 4 just goes black all of a suden. I doenst repond to anything, its not working at all at that moment. Also a reset is not possible at that time.

It is not possible to power on the iPhone. Only when connected to a charger is can go on. When its on everything is working fine, shows up in iTunes etc.

I replaced the battery with a new one a did a software recovery. Still the problems accur. It doesnt seem to matter if the phone is connected to a charging source or not, it just shuts off random. When the phone is on everything is working normally.

Another thing that i noticed, when its shuts down you wont see the spinning circle that you would see when manually powering off the iPhone, it just goes dead inmediatly. When the phone is powered off manually, it will also go on the normal way. When it shuts down itself this is not working

The battery is working fine, the phone accepts and charges it just like normal.

Home & sleep button are working perfect.

Any ideas what to do with this *****

***UPDATE*****

The iPhone is now constantly fibrating, it was charging on my pc. Now it wont go on but keeps fibrating :S

When putting the iPhone in DFU mode and try to recover it gives errors. like '2005 and 106'

Any ideas? Any help would be apreciated

Here's the story:

I rely on Siri a lot, asking questions like "What games are being played in the NBA tonight", and "Call (Person's name.) Just recently, when I open up Siri it does't let me talk or seem like it hears me. When I used to open Siri, at the bottom of my screen I would see the colorful, wavy line showing when I talk, but now it just shows me a colorful circle, and wont let me click it so it can hear me. I decided it was probably just a bug, and that restarting (holding down power button then turning back on) my phone would work. Now, I have done that multiple times, and it hasn't worked. I decided to just let it be, and I would talk to my dad about it that night.

But, later that day when I tried to call someone, I heard the ringing, but when they answered, I couldn't hear them and they couldn't hear me. They got the phone call, but still, we couldn't hear each other. When I told my dad about it later on, we tested the calling thing a few more times, always with the same result. (Happens with Android and Apple)

Upon further examination, I saw that when I called, I noticed that the speaker button was grayed/faded out. It wouldn't let me press speaker phone.

I also was curious if a "Hard Reboot" (holding the sleep button and the volume down button) would work, and all results were the same. Thanks for your time!

I just replaced the screen on my wife's phone after it was cracked. Everything's working OK now except for the Home button. It's totally unresponsive right now.

I disconnected and reconnected all the cables on the front plate and I'm still getting the problem. Enabling Assistive touch as a workaround works, but I'd like to have a functioning Touch ID and Home button.

I'm wondering what I could have done wrong that could be fixed I've seen plenty of issues that refer to Touch ID not working after this operation, but nothing that covers the whole Home button being dead. Any ideas?

First please forget my English, I'm French. My problem is that my iPhone 4s doesn't find any wifi. I've tried to reset the network and wifi. I opened it and saw if the antenna was connected (it was). I bought a new wifi and Bluetooth antenna and changed the old one, but it still doesn't work. I've no more idea. Please, it would be kind if someone could tell me what can I do to fix my problem. I've never taken my iPhone in for repairs nor have I opened it before my actual wifi failure. Thanks

I live in Ukraine. My friend from California bought iphone 6 and brought it to me, so have no possibility to return it back to Apple, we haven't got autorized apple distributors.

After unboxing I recovered it with my iphone 5s backup . And tried to make a call, all I heard was Nothing. Another person always hear me well but I don't hear anything even if I switch to the speaker and headphones as well.

I tried to use skype. it works I do hear everything. So made a conclusion that my earpiece works as well as speakerphone, because it works in youtube app and etc.

What I've already tried:

- Restore it from iTunes (3 times)

- Tried another sim card of another carrier.

- My sim card works in iphone 5s, checked all the problems might be related to carrier.

- Chatted with Apple support (2 consultants, 1 supervisor, all options exhausted)

I found smth related to my question here I can't hear my phone calls unless I put it on speaker., but in my situation speakerphone doesn't work also while calling and I'm sure my earpiece is not broken, it's some kinda software bug, that makes my phone a brick

Maybe smb have faced with such issue and can suggest something valuable,

thank you

p.s. sorry for my English

I don't know if i should try a different SIM reader, my abilities don't stretch that far so will have to pay. I'm more concerned it could be an issue on the board as the SIM reader looks perfectly fine.
