IPhone :: IOS 5.1.1 Update Causes Signal Drop

May 18, 2012

after i updated my iphone 4s to the new ios update version 5.1.1 i noticed my signal strength was weak.. like by three bars.. now i cant use data half the places i go, i called at&t and they reset the network stuff for me. still nothing. is there a way to drop back down one step? its obviously a software issue but we all know it takes a while for this stuff to get fixed and i kinda need my phone because its the only one i have. oddly enough the voice signal seems to be ok dispite the fact theres one bar.

IPhone :: Gigantic Software Update To Change The Signal Display?

Jul 15, 2010

The 4.0.1 update is 579.3 MB for my iPhone 4. That's a gigantic software update for just changing the display of the the bars for the reception, don't you think? Isn't the 4.0 software only like 350~400MB itself?

IPhone :: Not Picking Network Signal - Slow Signal Refresh

Mar 15, 2010

I live in a poor reception area on the Rogers network. I've noticed that when I go into the basement the phone drops a signal pretty quickly. I am okay with this and is expected. My issue is when I get back on to the main floor, the phone does not pick up a signal again for a long time. Sometimes even toggling airplane mode doesn't work. My wife's iPhone does the same thing.

Anybody else having this problem?

Galaxy S6 :: After Update 5.1.1 Data Signal And Testing Very Slow?

Aug 27, 2015

So i updated a few days ago to 5.1.1 Sprint service! A couple differences/ problems are: #1 Seems to me my data signal isnt good. It shows the LTE signal but when im surfing the next or even on ebay seems to just have the searching circle. then maybe a min or so later it will go. Ill surf again and data will just stop. It seems the data isn't communicating with the phone intermittently

#2 My text sending is way way slow now. Before update it would send pretty much within second of me hitting send. Now it displays the sending for a good 30 seconds! Sometimes even longer.

I have restarted multiple times/ update PRL/ Updated profile multiple times.

Motorola Droid 3 :: Skipping Music When Signal Changes After Update

Jun 13, 2012

I use my D3 to listen to music. I have the mp3s stored on a memory card in my phone. I have music version v4.1.513. Before the update the music played fine. After the update the music will skip/click when ever my cell or data signal changes. I work in a very low / no cell signal lab so the phone is continuously losing signal and getting it back. This cause the music to skip/click every time. Not related to the update my phone still does not like to play music over bluetooth and do navigation at the same time. I have the phone linked to my car radio for navigation and I listen to music from the phone. It will reboot after about 15 minutes of use.

Google Nexus 5 :: GPS Dropping Signal After OTA Lollipop Update

Nov 24, 2014

My nexus 5 GPS used to work GREAT under kitkat. However, after the Lollipop OTA update the gps signal keeps dropping and I am not able to use any navigation system.

I did try the factory reset but it didnt work.

A friend of mine is also facing the exact same problem, we both have the 32GB model.

My girlfriend, however, has not faced any issue after the ota update (she has the 16GB model). Her GPS works great! Our basebands versions are exactly the same.

I really need the gps. I use it almost daily!

Motorola Droid Razr :: Poor Signal Strength After ICS Update?

Jul 5, 2012

I updated my Razr Maxx on Monday. Tried doing it sooner, but was getting the bug where it wouldn't validate the update. Ever since my signal strenght has been much worse than before. I no longer get signal in some places that I go for work that I had no issues with before. In those I still get signal I have issues connecting to data where I never did before. Even at home my signal is much worse.I realize that ICS displays the strength differently, but the way it displays should have nothing to do with actual usability. Can hardly use my phone at all anymore while working whereas I had no issues before update.

Motorola Photon 4G :: Signal Bars Vs Signal Strength?

Jan 31, 2012

I was wondering if anyone knows what algorithm is used for the signal bars on the Photon 4G. I have found that there seems to be no correlation between the signal strength (in dBm / asu) in Settings -> About phone -> Status and the signal bars that are shown. Often the signal bars will shoot from 1 to 5 or 6 even with really low signal ( ~97 to > 100 dBm) that doesn't fluctuate.

BB Tour 9630 :: Tour Loosing Signal And RIM Sent Software Update

Apr 26, 2010

My Tour is 3 months old. Suddenly calls are dropping in the house and the battery charger is taking 10 hours to charge the spare OEM battery. Running the 5.0.419 and it's been fine. Verizon came out with theirs and it's so bad I went back to 419. Now I have an email from RIM saying new software for the phone is available but it doesn't say what version it is so I'm afraid to load it. Any one else have same issue? Phone was fine after going to the first 5.0 for 2 months but now after having changed from Verizon's 5.0. (been a month or so) the issues started about a week ago.
