My iPhone 5 is really dim. I'm unable to pass the welcome screen? What should I do?

Your screen brightness is likely too low and it's probably too bright where you are. If you have iOS 7 you can change the brightness without unlocking. Turn the screen on and then swipe up from the bottom of the screen all the way to the top. This should open up command center. Now, in the vertical center of the screen will be the brightness slider. If it's dark the slider would be around half and inch from the left edge of the screen. Start from there and just start sliding to the right until the brightness goes up.

Instead of guessing where it is you could also cover it from the light and look in. You should be able to see the slider if the phone is shaded.

  • Why is my Wi-Fi bar grey or dim on my iPhone 4S? I just got an iPhone 4S from a girl and after I set it all up (it's not on a plan) and the Wi-Fi bar is grey/dim and I can't connect to Wi-Fi anywhere and I can't slide it.
  • Why does the brightness on my iPhone 5s dim randomly? I've had my iPhone 5s since November and I've noticed that the screen occasionally dims a bit when it's on full brightness. It's not a huge issue at all, in fact when it dims it's barely noticeable, but it's just been annoying me lately. Does this happen to anyone else with an iPhone 5s? Other than this issue my phone is perfect. And I've also turned auto-brightness off so that's not the issue.
  • Why does my iPhone randomly dim itself? I've had this issue for quite awhile. It's an iPhone 5 with all recent updates. I've looked up how to fix it, and so far nothing's worked. Auto brightness is turned off, white point is off, and I've reset all my settings. My brightness is turned all the way up, but when I move the slider past halfway it stops getting brighter. Some days it won't dim at all, other times it seems to spend most of the day dim.
  • Water damage on smartphone causes super dim screen? I dropped my Samsung Exhibit directly into a cup of water, and immediately removed the battery and put it in a bag of rice overnight, it still works but the screen is super dim, and adjusting the brightness does nothing. I can only see what i'm doing in a very dark room
