iPhone 5 screen dims by itself..

Don't take this the wrong way but at this time, no one here is going to determine if your phone is broken.

If you are referring to the screen dimming issue, you have 1 choice: Ignore it. This is affecting millions of phones and the only fix right now is to just ignore it. If your screen dims, go to settings---->general-----> and look for the Screen Brightness selection, touch that and your phone will act normally.

There is nothing anyone can do at this point ntil Apple fixes this.

1. No you do not have a faulty SIM

2. No your phone is not broken

Thanks I'm sorry if I i'm bothering you,it's just that i don't know nothing about tec !!! :) it's just when in the left hand corner it said that my sim wasn't valid and i got worried that my phone was broken :)

LOL, not a bother - what I wanted to stress was that sometimes technical people will confuse the real issue with another issue.

If your SIM is malfunctioning though - go back to your provider and they will give you a new SIM because it IS possibly broken.

Have a great day.

Thanks but its not doing it any more should I just leave it?

I would leave it alone for now and if it happens one more time, I would take it back to your carrier and ask for a new SIM, chances are they will swap it out for free as long as you give them back the broken one.

Sit tight and hope it doesn't happen but I will tell you that SIM failures are easily fixable by just replacing them.

Thanks it hasn't happend since but if I keep it in would it couse problems to my phone???

The only thing tha a bad SIM will do is stop your phone from functioning temporarily until you replace it with a replacement SIM.

If your phone is less than a year old, it is still under warranty and I would take it back to where you purchased it, or any Apple store for a replacement.

Older than a year old? our phone carrier will probably give you or send you a new one.

On most carriers, call 611 from your phone (a free call) and their customer service can guide you.

I got my phone at xmas so should I go and replace it?

@ Sefanopica1998 : This community is supposed to be a helpful support for technical questions and not a chat room where people spend their time chatting about topics that are useless for the community.

The last exchanges had nothing to do with the topic of the question which is a dispaly fading away. Nothing to do with SIM locked or whatever. Please respect the community and stop polluting this forum. Thanks !

I just want to no what to do!!! Do you think I should replace my phone? Why did it say sim not valid??? If you just explained to me why i won't be asking these questions!!!

If you would like to answer me contact me on this apple support or on this email:sonomilanista80@gmail.com
