Guys,
I just just updated my 3GS to a 4S, and I'm noticing some strange behavior with the HFL. The signal strength meter in the HFL display seems to get 'stuck' shortly after I lock my phone. For example, if it gets stuck at one bar, I can drive around all day and it will always say one bar. However, if I drive into a higher strength area, then pick up my phone and press the home button, I can watch the signal strength meter on the phone immediately start climbing up. The HFL display then reflects that.

Has anyone else noticed this behavior? It's kind of annoying because I can no longer just hit the HFL button to check my strength before making a call.

I have some theories on this, but I'm hoping it's not just a problem with my particular 4S. Of others see it, then I can rule that out. I'm wondering if it is a change they've made with iOS5, or if it is related to the 4S and/or Bluetooth 4.0. Bluetooth 4.0 is supposed to be consume less power, and maybe it shuts down the signal strength meter updates after a period of time. Then again, it could be something that Apple did to squeeze more power out of the 4S battery - ie: shut down signal strength meter updates when the screen is off. As I said, I do see the signal strength meter on the phone gradually rise (2-3sec) to the new level AFTER I hit the home button. It seems to start out at the 'stuck' point.

Any thoughts?
Thanks,
Mike

 

I'll look at mine, but maybe the phone is hibernating and not communicating its signal strength. I have the new iphone 4s too, ill take a look at this today and report back.

 

Read somewhere (4G-TL forum?) that the i-phone OS5 is not working properly with Acura HFL. Do a search.

 

Thanks guys.... I haven't seen anything reported on the Apple 4S forum, and my various Google searches came up dry. I'll try going directly to the TL forum.
