Ugh! same problem as original...

[thechidz]

there is some glitch in the OS that happens when you use the phone as a handset. You put the phone up to your ear and the screen is supposed to go black to reduce heat against your head. Only problem is it doesnt go black until you take the handset away from your head and then it stays black and you have no access to the touch screen!!! Ugh this happened on the old iPhone and I hoped would have been fixed by now, it is soooooo annoying and inconvenient

Do you have the phone in a case? If so, is it one designed for the previous iPhone? The reason I ask is that there is now an extra sensor that gets covered by old cases and causes this problem...

Isn't it to prevent your head from pressing things on the touchscreen?

Either way, I've never heard of such a problem. I've heard of jailbroken phones in which the screen doesn't shut off at all when you put it to your face, but I've never heard of it shutting off after you take it away.

this might be the problem. I will try it and report back

It's probably the sensor being covered up

P.s. lcd panels don't give off much heat. the screen blanking is to save battery.

yep that was the problem. thanks. guess Ill just have to use headphones.

The way that sensor works is one of the cooler things about the iphone 3g. I'm new to iphone, but it causes me to smile each time I go to end a call and the screen comes back on when I move the phone away from my head.

Simple pleasures I guess.

the screen takes a bit to turn on after i move the phone away from my head.... its a pain.

I love my case. Its a compact wallet/case. the best Ive found

 

[sr5878]

if it's a rubber/plastic case, try boring out the holes for the new sensors?

I love it too. Especially when I have to go through dialtone menus (Somehow Apple has managed to actually make those awful things enjoyable).

It does seem to take a half second too long sometimes, though. Maybe with the post-2.0 update it will work better?
