2.1 Fixes 3G to Edge Dropped Calls

[pj rage]

If the db measurement is measuring the signal strength to the phone, then yes, -81 is a better signal.

If the db measurment is measuring receiver sensitivity, then -93 is "better".

I have a gut feeling that the firmware will just display a higher number of bars which will placate 95% of the userbase. Unfortunately, the number of bars a phone displays is really useless, however most people consider bars the ultimate measurement.

Apple also may have increased the receiver's sensitivity to signal which would yield better results. We'll see.

I don't know why it would be showing receiver sensitivity? It should be showing total loss from the tower to the chipset, ie "signal strength."

And remapping the bars to the signal received may be a placebo and most people will think they have better signal, and really they don't, but what I'm personally interested in, is whether or not they've remapped other areas of the firmware also. Such as the area that determines at what signal level will the chip switch from 3G to edge. Also, at which signal level will the phone display "no service." Rumor has it that they've been overly conservative, requiring that the phone have more bandwidth and signal available than is actually necessary. Fixing this would be awesome.

ONLY remapping the bars would admittedly do nothing except make people feel a little better, but if they also remap other things too, because they have been overly conservative across the board, it could have a REAL impact on the phone's performance with respect to signal received.

Wrong.

Putting your finger over the sensor would make the iPhone think it's in a dark place. Correct? This would dull the screen not brighten.

Auto brightness is meant to brighten the screen so you can see it in bright light conditions and lighten in dark lighting. Not the other way around.

Auto brightness has a purpose and it should work and needs fixing.

Turning off is only a work around not a fix.

what if your fingers was covering it when you unlocked the phone and then you moved your finger? Wouldn't it then brighten up thinking you have gone into a nice bright location?

Has the issue of the screen suddenly brightening up been fixed in this update?

I'll explain further. I think it maybe to do with the auto brightness option.

I can be using the iPhone inside (so no change in lightning conditions) when suddenly for no reason the screen will brighten up by itself. Going sleep/wake up fixes it until next time.

Others seem to be having the same problem too.

That's funny. I have this problem too.

But I describe it as "phone is too dim at first, but will brighten over time." I guess I just like it brighter

My auto brightness has definitely been malfunctioning too.

They need to release this in a hurry. I'll take it with any leftover bugs and all. It can't be worse than what we are living with now. Interesting that they removed push in beta 4 of 2.1.

Yep that's the way it works. Seems to depend on how bright you have it set and uses that midway setting. ie. -10% - 0 - +10%. Not having any problems with sensing the light conditions.

The problem I'm having is it going to full brightness at times. Almost like the iPhone forgets what the brightness setting is set to. It is a auto brightness issue as it doesn't do it if it's switched to off so it seems.

NDA or not, gotta admit it takes balls to install a beta OS that specifically states that once installed you can NEVER go back to 2.01.
