Nexus :: 3G / 2G No Data - Vodafone N1 - Signal
Jun 30, 2010
My N1's been working perfectly since I bought it from Google in January... until today. I have a good signal and can make / receive voice calls and texts. However, I'm not getting any data and no 3G / 2G etc. icon is showing on the bar next to the signal strength icon. I've tried going in and out of airplane mode, going to 2G only, rebooting, removing battery and reseating the SIM and SD cards.
Vodafone have confirmed there's no issue on their side (other Vodafone users nearby have aren't having problems) and have even swapped my SIM with no effect. I phoned the HTC help line (very quick and helpful BTW), who tried setting up a new manually defined APN. Nothing's worked.

I want to reach out to others here before I take my Moment back to Best Buy to exchange it for another Moment.
My signal strength fluctuates wildly just sitting in the same spot. With the Hero I got a constant 5 of 6 bars, but the Moment will vary between 0 and 5 of 6 bars. But it's more complicated than that.
It seems that whenever the EVDO data kicks in, it causes the signal strength to drop to 0 or 1 bar. Once the data is idle, the EVDO indicator turns grey and then changes from EV(^v) to EV(D). At that point the single strength will return to 3 or 4 bars.
At times, though not as consistently or often, the EVDO connection will fall back to 1xRTT and will switch between them every few minutes. This will occur even when the signal strength bars are in the 3 to 4 range.
So, the my questions are...
Does the signal strength apply to the data signal or just the voice signal?
Is there any legitimate reason for the signal strength to vary wildly like I've described, even when sitting in the same recliner where the Hero had a constant 5 bar connection and data service that never wavered?
Is anyone else having signal strength and/or data service issues?
Should I exchange the Moment for another Moment or will I likely experience the same issue?

I have an unlocked Hero using a Sim from Vodafone. So far all seems ok apart from one strange anomaly. When I'm in my office I have to use a Vodafone Gateway as there is no regular signal here. This works fine, however my phone thinks it's in deepest Russia and it's making me feel cold being constantly told that the temperature is -15 DegC and sunny. Is this because Vodafone have a server hidden in the darkest depths of Russia and is there any way I can change this apart from manually telling it where I am each day?

Absolutely love the phone - even got my mate jealous who owns an iphone lol !!. I've always been a Nokia man through and through until I got the N97 - Nokia really let things slip here so here I am Anyway, I can receive picture messages via MMS ok but cant send them. It tries but fails. Does the Nexus scale photos down to MMS limits or do I need different settings for Vodafone UK ?.

My Desire has started acting strangely today. Wifi works OK, phone signal works OK, what doesn't seem to work all of a sudden is the data signal. Any data signal, 3G, HDSPA or even GPRS - there is no icon in the notification bar and no access to the mobile internet.
I've tried:
* rebooting my phone
* turning APN and on again with and without Wifi
* checking my APN settings (OK)
* reinstalling the newest radio (one that ends in 20 - was working fine up to now)
* reinstalling my version of 2.2 (Defrost 2.5a)
* checking my carrier's site to see if there are any probs (Virgin Mobile)
* Oh and I've travelled about 50 miles today on my commute from outside London to central London with no signal at any time so I assume it isn't a local antenna problem.
All to no avail. II first noticed it at 0700 this morning - so it has now been like this for nearly 12 hours. The icon and connection remains stubbornly off. If I wasn't getting wifi or signal I would be really worried, but the fact that I can fills me with hope that it is either a setting or user error.

So my Desire's been working perfectly since I got it on Saturday. Today I've noticed that it's not using mobile data. Not an issue at home with my wi-fi or at work* but it's irritating. I haven't changed any settings and triple checked that every box that should be checked is. Anyone else with a Desire having this problem? Is there a T-mobile hiccup today?
Though I can't see how it would make a difference, today was the day my old number got ported over. Oh. They mentioned there would be connectivity problems during the transition period.

I know that it's possible to determine the data connection type (WIFI/or cellular) through Android, but is it possible to determine the cellular connection type and strength?
I have an app that downloads some images and I have found that on GPRS or on 3G with weak signal that this download process slows up the app unacceptably. What I want to do is say that if you have either WIFI or a strong and fast data connection then download; otherwise display a default placeholder image.

I'm writing an app to monitor detailed radio data coming off the phone that I'm sending back to my own server that is collecting this information from a number of different devices. The purpose is to analyze the data from all devices, and generate a kind of "real-time network coverage" pattern.
The data I'm looking for is "Eb/No". From what I understand this is interchangeable with the term "Ec/Io". My first approach lead me to the new Signal Strength (http://developer.android.com/reference/ android/telephony/SignalStrength.html) support in Android 2.1. This is great, however you can only get Ec/Io values for "CDMA" and "EVDO" networks. My problem is that I'm on ATT, where I'm "WCDMA".
I was hoping Android would give me the "CDMA" values from Signal Strength changes (since "WCDMA" is somewhat similiar to "CDMA"), however the update has the gsm flag set to true, and it's giving me values for the gsm signal strength and gsm bit error rate instead.
For example, in my PhoneStateListener:
CODE:....................

I've noticed that even when I have 3g or 4g, certain apps never connect to the Internet. The apps I've noticed that have this problem are sound Hound, Google now search, spotify and words with friends. These apps will fail to connect to the Internet and say I have no signal, yet I can open Google Chrome and open a Web page no problem (even pages I don't visit that aren't stored in cache) or use the Chive app.

Some professional reviews (engadget and phonescoop) have noted signal strength issues with the Droid 2. For example, see:
Review: Motorola Droid 2 : The Three S's (Phone Scoop)
Particularly for those who have/had other Verizon phones, have you noticed any signal strength problems, trouble with calls, or slow data?

I've tried searching for an answer to this in the forums but I can't find someone who has already asked it.In any case I'm wondering whether its possible to use a Nexus One without a data plan. I have access to wifi pretty much everywhere I would use my device and thus a data plan really is not worthwhile for the cost.That being said I know that for other android devices, the very first time they're turned on, the user is required to connect to their Gmail account via data. Would I run into a similar situation with the Nexus One? Is it possible to use the device from the get go without any data? Do any of the primary apps(besides google maps obviously) absolutely require data to be used?

Whenever I use the data connection, the phone crashes and it reboots.Sometimes it happens some minutes after browsing, other times it happens once the packets start flowing, and other times instantly just after a reboot, which forces another reboot again.Some applications started crashing too, mostly games.Since a couple of days ago I've been getting some restarts just browsing on the settings too.I did a factory reset which proved unsuccessful, and I've been wondering how to do a full wipe of the system to reinstall Android and hope that fixes it. However, I fear it could be a bad memory block or some hardware problem that's causing the crashes.AFAIK, there haven't been any incidents (drops, spills, etc), the problem just started happening and has increased in frequency.Also, could someone guide me to how do I reinstall Froyo?

The device : Google Nexus S
The problem: Broken LCD display... The official Samsung service replaced the LCD display and installed 4.0.1. The result is that I lost all my data (all photos and videos are lost).
I tried every recovery tool available (from R-studio to Photorec)... No data recovered... Is there any chance to recover the previous configuration or may I start to take it for granted that all my photos are forever gone ?

I just created a second user, and i'm wondering if there is a way to move an app (and its data) from the primary user to the secondary user. I have already tried using Titanium Backup, making a backup in the primary user, and restoring it in the secondary user, but it didn't work (it only restored the data on the primary user again). I tried to find a similar thread, but didn't find one.
I have a Nexus 7, running ParanoidAndroid 3.15, and I have root access on both users.

As Nexus One is the only model which has already "partly" updated to Froyo,Before Froyo, if I wanna enable/disable mobile data usage, I used a passive way, changing the APN server setting, to fool the system so it couldn't connect.In Froyo, there is a new option under Setings -> Wireless & Network Settings -> Mobile Networks called Data enabled/disabled, which is a much direct approach than changing the APN.But up to today, I've yet to see a widget which targets at this option. Currently I hv made a 3G shortcut to that setting page on to my home screen. Really hope there will be a toggle widget instead!So how do u guys enable/disable data usage at the moment without a handy widget on Froyo?

And it's grayed out so I can't add an account.
The phone is signed into my Google account. At least I think it is - it's rather confusing how many different things the phone can be signed into.

Is there an app that can turn on data for a set time then turn off then on in intervals. I've noticed that data drains my battery compared to having it off so I was wondering if there is an app that is like a timer for data. Galaxy Nexus

I can get a few minutes of 4G signal at my home per day, but when it drops out and 3G takes over, the signal will flatline and boot me offline. My 3G speeds are usually around 56-150Kbps or less, and my 4G speeds are around 2.5 Mbps What would cause this ? According to WiMax location sites online, my nearest 4G tower is .52 mile away. I would think that if I actually get 4G signal, then 3G would be constant. Turning off 4G doesn't help either. Is there some setting that I could have turned off that would cause this ? Running stock EVO on 2.2 all the latest updates

How can I set my Galaxy Nexus to prefer WiFi for data over the Mobile Network? I have to go to settings, turn off "enable data access over mobile network," then cycle WiFi on-off several times before the phone will connect to my home router. Router has two channels, both a WPA2 encrypted one, and a "home guest" (open) one. Both show up as disabled until I cycle the WiFi off and on several times. There must be a setting to tell the phone to prefer WiFi -- no?
