Android :: Extremely Long DNS Lookup (and Failure) On Mobile Network

Oct 14, 2009

This happens only when my G1 phone is on T-Mobile network: I found that when I try to go to the browser, and type the address:
http://i0.sinaimg.cn/
The browser tries to load the page, but no progress is shown for more than 2 minutes. (I have full 3G signal; all other addresses work just fine). Eventually when I tried to access this URL in my Java code, I found a similar long delay when I try to open the HttpUrlConnection, and eventually I get this exception:

I/InetAddress( 1940): Unknown host i0.sinaimg.cn, throwing UnknownHostException W/System.err( 1940): java.net.UnknownHostException: Host is unresolved: i0.sinaimg.cn:80 W/System.err( 1940): at java.net.Socket.connect(Socket.java:1002)
Why would DNS take so long? Also, if my program tries to issue the same HTTP request again, the same 2+ minute blocking happened. Is this an Android bug or a T-Mobile infrastructure bug? It seems the Android API should try to time-out faster, especially on the second attempt.

HTC Desire HD :: Mobile Network Widget - Switching Off/on Mobile Network Setting From Home Screen

Oct 29, 2010

I have been trying to find a way of quickly switching off/on the Mobile Network setting from the home screen. When searching Google there's loads of pages stating that it is an HTC Widget that can be added. I have checked all the widgets on the Desire HD and cannot seem to find it anywhere. I am using an unbranded handset.

The Desire HD manual even states "You can also add widgets that allow you to quickly switch on or off certain settings of your phone, such as Wi-Fi, Mobile Network...".

Does anyone else with an HD handset have this widget ?

HTC Incredible :: Message Not Downloaded - Generic Network Failure

May 1, 2010

New Incredible, setting up and downloading everything in sight on Thursday. Late last night (Friday) started having issues with mobile network and internet access while not on wi-fi. I have been using wifi predominantly so I think this issue was in the background but I didn't notice because I wasn't using 3g internet access. When I shut off wifi, I was getting access errors and, in my QuickSettings app, it said that there was no APN configured. The HTC settings app, under mobile network, simply said "turning on".

Searched around and discovered that this might be a problem with the app itself (QuickSettings) so I uninstalled it, did *22899 and rebooted. 3g problems went away but now I'm getting intermittent status bar messages that say "message not downloaded - generic network failure".

I am using Handcent and I *think* I'm getting all the messages I've been sent but how could I tell? I've been getting some, at least. I turned off the auto-retrieve for the HTC native messages app but I'm still getting the status message periodically. The phone will vibrate and notify like I've gotten a SMS but all I'm getting is the error message - about every 10 minutes.

From searching around it appears that this has been a thing with the Eris but the fact that it *was* working and now it's not is confusing to me. Is there a known conflict out there with an app combination that does this? I searched the forums and the google but I'm coming up empty.

HTC Wildfire :: Unable For Sending MMS - Generic Network Failure

Oct 26, 2010

I've seen this problem on a bunch of other android phones but nothing specifically for wildfire.

When sending MMS I keep getting a notification saying 'message not sent. generic network failure' until it eventually aborts altogether.

I think the problem is at least partly coz I'm using an unlocked vodaphone handset on orange, so the APN isn't properly configured.

Ideally can somebody with a Wildfire or similar model on Orange give me the correct APN settings from your phone? Or at least link me where to find them - it sounds like every other provider has the details on their website but can't find anything on orange.co.uk

HTC Droid Eris :: 3G Mobile - Data Connection Failure

May 5, 2010

I purchased an Incredible, which I was not too happy with, so I decided to send it back and reactivate my Eris. My Eris was at 2.1v2 at the time. I called Verizon and had them do the switch through their customer service number.

Immediately I began to notice that I had a lack of 3G. My Turn Mobile On setting would be stuck on "Turning On". I could force it by switching airplane on and off and then using the power button to choose Mobile settings. Once I'd get it on, 3G would be spotty and drop in and out, and when I do have it it is ridiculously slow. Speed test shows downloads of 302 kbps and uploads of 1023 so it appears I have upload 3G but not download. Many times throughout the day I get data connection failures on apps requiring internet.

So, I called Verizon, we went through all their steps including escalation to tech support and they decide it is my Eris (which worked perfectly previously). They are sending me a replacement. In the interim, I went back to the Incredible. And immediately had the exact same problem on the Incredible. I called Verizon, and went through all their steps, and now they want to send me a new Incredible. I went back to the Eris, and upgraded to 2.1v3, still the same problem. I am 100% confident that when I get the replacement Eris it will solve nothing. APNs are at correct default.

Jul 5, 2010

I seem to be seeing an issue with the data network access on the EVO. When it happens none of my applications get internet aceess and my mobile network status says "turning on". The only way I've found to fix it is to pull the battery. Any one else seeing this? If so is there a better fix than pulling the battery?

HTC Droid Eris :: Mobile Network ON - Can't See That Have Any Network Traffic Or Any Apps Running In Background That Are Syncing Data At All

May 29, 2010

My eris has always has pretty alright battery life, what I would expect out of a smartphone, if unplugged at 9AM it usually was running on its last leg around midnight. I've had it for over 5 months now, I've always had it activated on alltel, I installed the 2.1v3 leak before the official OTA was out and just lately it seems like there something very wrong with my battery life...

If I unplug my phone at 9AM within the past week and occasionaly check and respond to a text message, my battery had been down to almost 30% by NOON... what?..

I have noticed that if I disable Mobile Network (3g/1x data), the thing lasts all day and some... If I turn mobile network ON, I can't see that I have any network traffic or any apps running in the background that are syncing data at all... I've had google account sync mess up on me before and have to reset my google account because it gets stuck in a syncing loop, but its not doing that, already checked. Very weird.

Anyone thing it could be something wrong in my ##PROGRAM#/##778# provisioning menu, maybe something got changed?.. Maybe it could be do to Alltel's AT&T merger that's happening right now, maybe some 3G tower's radios are turned off or something...

HTC Desire :: Switch On Tethering OR Mobile Hotspot - Mobile Network Dies

Sep 21, 2010

Android Version: 2.2 T-Mobile branded
Network: Base - a brand of e-plus, Germany
Taskiller Used: None
Issue: Switch on tethering OR mobile hotspot ->mobile network dies

I've installed Froyo on a T-Mobile branded Desire. After the update, turning on USB tethering leads to immediate loss of mobile network - it just turns itself off. Same goes for the mobile Wifi hotspot: turn on -> for 2 seconds, it's working -> mobile network drops off. Moving into airplane mode and back brings back the network, but tethering is a goner. With 2.1, USB tethering had worked. I'm on Base, a brand of e-plus. I've talked to their customer services, they say Base absolutely supports tethering.

My test version will establish a connection if I have both phones on a lan using wifi but when I use T-Mobile's network a connection is not established. Could this issue be a port or ip address?

Android :: Cannot Receive UDP In Mobile Network

Dec 14, 2009

I am writing a UDP client/server application. The android phone (client) can send and receive UDP packets if connected to wi-fi. When using mobile network (2G), however, it can send packets to the server, but cannot receive packets. The server does receive and send back packets in all cases. The client side code is as follows: byte[] buf = new byte[4096];DatagramPacket packet = new DatagramPacket(buf, buf.length);while (true) {packet.setData(buf); socket.receive(packet);

Android :: Making Request Over Mobile Network When WiFi Enabled

Nov 19, 2009

Is there any way for an application to force a network request to go over the mobile network if it's available in preference to WiFi? I'm looking at ConnectivityManager#setNetworkPreference, but there's no documentation, and looking at the source seems to suggest it's setting a global preference somewhere which isn't what's required here - I just need to force certain requests that need to go over the mobile network to ignore WiFi.

LG Eve :: Turning Off Mobile Network With LG Eve

Dec 27, 2009

I have a HTC Hero for the last few weeks and really happy with it. I friend recently got the Lg Eve and was looking at it. She wanted to turn off the Wireless Network to cut down on when it accesses the 3G network, but unlike the Hero, I wasn't able to find the Mobile Network setting under Wireless Controls.We took it back to the Rogers store to ask if he sorta blew it off saying she didn't need to turn it off and help her installed a counter to track her data usage.So is there a way to turn it off when it's not in use?

HTC Desire :: Mobile Network Or APN?

Jul 6, 2010

As part of my battery saving techniques i often use a widget which turns off the APN. This has direct effect on disabling 3g as it no longer flashes in the task bar, but can someone explain the difference between turning off the APN or turning off the whole 'mobile network' (holding the power button and selecting mobile network off)Also, do both ways save the same battery?

HTC Incredible :: Mobile Network On / Off

Just a quick question for anyone interested: Earlier today, I was running low on battery. I decided to toggle Internet access (mobile network) in order to save battery. However, I'm quite reliant on Google Voice. Throughout the day, I turned the mobile network back on briefly to receive messages. Is this constant on/off bad for the 1x/EV radio?
