Iphone 4S WEAK Signal

Started noticing that Iphone 4S often has a WEAKER signal than another 3G phone I have on the AT&T network.  I'm talking, within 1-5 cm of each other!  (so can't be due to location).  Normally, I'd guess probably different manufacturer and different signal strength algo's... but the difference is HALF signal to FULL signal.  Too much to be just a algo problem (unless someone really screwed up the SW/FW).

 

So I called AT&T via chat, and all they could offer to me was to try:

1. Go to store and get a new SIM.  (Well, I took out my other microSIM in the good 3G phone and swapped it with the Iphone and STILL got the lower signal with the Iphone, so can't be the SIM).

2. RESET Network Settings... this "seemed" to help a little... but come on... do I have to do this EVERY time I have this problem (have had to do this twice now).. and every time, I have to re-enter the passcode on my home wifi.

 

I just upgraded my wife to a 4S also from a 3GS, and now, she just got the SAME problem and I had to reset her network.

 

One thing the AT&T person told me, is that Iphone 4S actually supports HSPA+, so because of that, it might affect signal strength on 3G only networks.   I don't know if I buy this or not.  That would be completely stupid way to design something.  (I'd buy slower getting a signal but a consistently a weaker signal?). 

 

AT&T or Apple... you NEED TO FIX THIS.

Only way to fix is redesign the phone. It has to do with the antenna band around the device.

Might as well return it if you can or put up with the device for the next 2 years

Thanks JFiz... I thought the antenna design problem was "fixed" with 4S?  There was a visible public issue with the 4...

 

Or is this another issue?  Can you give more info?

When you say weaker, are you dropping calls or just observ the meter to show fewer bars?

Meter.  And just so you know, I've compared 2 different Iphone 4S side by side (mine and my wife's)... and seems to make a difference if you reset one network setting but not the other when both have weak signal.  In fact, just did it again yesterday... when my phone signal was at 1 bar... and hers was at 4... and I reset mine, and mine went to 4.

Sounds like a software issue. I would consider either reseting your network settings as you have done more often. (You should not really need to do this) or restore your iPHone and setup as new to also wipe out any bad settings that might add to this issue.

As for the Antenna, Apple did make some changes between the 4 and 4S. What I do not know if the situation was resolved and/or just improved. The 4S antenna is definitely different from the one in the 4.

Thanks... for now, I'll keep resetting the network... restoring to "new" seems a bit crazy (not to mention it's just trial and error hoping it does something... not going to do that... if it's a SW issue, someone should fix it).  It's akin to reinstalling Windows on a PC.  If you really have to do that on a Iphone.... I'm not sure I want it anymore.  I also haven't heard of same issue on Verizon from my friends with Iphones on that network.

Do not disagree that it is not a common issue but something is corrupted. Try a restore and reinstall your backup. Hopefully the flaw in your software is not part of your backup. Since this is not widespread, it may not be fixed with an update given a restore probably fixes your issue.

One more comment, there are probably folks on Verizon and Sprint who also have issues that result in needing to restore their iPhones to fix some issues. This is not just isolated to ATT iPhones.
