Here's my problem, the data connection will periodically not work (3G & WiFi still show and strength is not a factor, also no 4G in my area). My current workaround is to enable airplane mode and then disable it, if this does not work then I restart the phone (rare, but it has been necessary).
I have a completely stock VM CDMA ROM, S-ON, not rooted, all system updates have been applied, etc, since up to this point I've been content with what I have. When I go on to the internet with an app (shows connected) and I'll get an extended blank screen from the app I'm using before it tells me there is no internet connection. I'm at a loss as to what is happening, though I have noticed that it frequently occurs when I unlock my screen.

My Amaze is having some serious Mobile data (4g/2g) connectivity issues. The problem is this:
1. When turning the screen on, the notification bar shows no mobile data connection, regardless of how many bars I have. Mobile data connection is always enabled under quick settings, but for some reason the phone still can't establish a connection for quite some time, or until toggling mobile data on/off a few times.
2. After finally getting a connection, the phone has further problems connecting. Even though 4g/3g/2g icon is present on notification bar and mobile data is enabled in quick settings, using browser will return only "page not found" errors, and apps will not function properly due to them not having a network connection (foursquare and spotify most especially). Looking at the 4g icon on the notification bar, I can see the "up" arrow flashing as if the phone is sending data, but the "down arrow" is dead as a doornail, not lighting up or receiving anything back. This happens regardless of how many bars I have.
3. On the rare occasion that the phone's mobile data connection does work, it's super slow and acts more like 2g than 4g. Simple web pages take anywhere from around 30 seconds to a minute to load, and spotify cannot stream a song without having to buffer constantly.
Does anyone know how to fix this issue? Or had experience with it? Just in case your wondering, I haven't gone over my 5gb data plan yet (see attached image).
Issue resolved.
Apparently this problem is a combination of 2 glitches:
1. When upgrading to a new phone, despite how much data you used in your plan during the billing cycle, on the T-Mobile My Account website, the widget which shows how much data you've used will only reflect the data you've used on the currently activated device. Before I upgraded to the Amaze, I had exceeded my 5gb limit on my Nexus One and was being throttled by T-mobile to lower speeds. My next billing cycle doesn't start until Dec 27th, so despite the fact that I've only used about 70mb on my new Amaze, the 6 gb I already used on my Nexus One still counts for this month's billing cycle even though the T-Mobile website doesn't reflect it.
2. When throttling, the Amaze, which by default is set to WCDMA/GSM auto, is supposed to automatically switch itself off of 4g and only allow 3g/2g connections. It doesn't. For some reason, it stays with the 4g connection even though the connection is, at best, intermittent. This is the cause of the "page not found" errors and app network errors I was having.
So, for anyone else who is wondering how to remedy this, the fix is simple. Go into Settings>Wireless & Networks>Mobile Networks>Network Mode, then tap "GSM only". This will cut off the problematic 4g connection while still allowing for 3g/2g connections. While noticeably slower (especially where I live, since the Florida panhandle only has 2g and 4g, no 3g), the mobile data connection is solid. Have yet to have any connection errors or experience any intermittency. Still, can't wait until the 27th when I can test out the full power of the 4g connection.
Rooted stock ROM Verizon I605 running 4.1.2.
I was in Korea for the past 6 months and just got back the other day. Before I left, I never had any problems, but since returning, my wifi and data are on at the same time, and it's causing me problems. Here's what's going on:
If I just have mobile data on, everything works as it should. If I turn on Wifi, it will connect, but the data connection will also remain, and my internet speeds will become spotty. If I turn on mobile data and just try to use wifi, the Wifi icon appears (with the orange/green arrows indicating activity), but apps don't connect. Facebook automatically tells me "No Internet connection," Opera won't load pages, Google Talk can't sign in, etc. If I turn mobile data back on, things work again, albeit slowly.
The strange thing is if I turn on Airplane Mode and then turn it off, leaving data off, my wifi will work 100% normally. If I try to turn on mobile data again, I get the same issue.
While I was away, I replaced the SIM card so I could use my phone over there. I messed with some APN stuff thinking I would be able to get data on my phone in Korea, but that didn't work out so I returned my APN settings to default. I have a feeling that's the source of my problems, but I have no idea how to fix it. I tried restoring my APN settings to default through the settings, but that didn't fix it either.
Any help at all would be appreciated!
If it helps I have been seeing the same thing. I'm on CleanRom 3.5 (Verizon Rom base) and PB&J kernel. It seems to be hunting between them even when in strong wifi signal.
Interestingly enough it's not doing it right now.
I'll keep a closer eye on it now.

In my case, it's a constant problem (unless I manually go into airplane mode, like explained). It doesn't work sometimes and not work other times.
I'm trying to use wifi at home, so signal strength isn't an issue either.
Hi everybody,
I'm facing an annoying problem: when my phone "considers" the wifi signal "too weak", it automatically switches to mobile data (even if the latter are disabled), the result is the mobile frequently drops the wifi connection in some places at home where the signal is a little less intense.
In my phone, options in the advanced settings of the Wi-Fi do not let me choose anything about automatic switching from wifi to mobile data (or such options aren't displayed)...
What can I do?
Is there a way to access "hidden" settings like the ones mentioned?
Thanks for your answers!
ZTE Grand X In, Android 4.0.4.
Google Talk services are draining battery, that seems to be known problem. But, this issue for this topic is different one.
I checked Better Battery Stats, Better WiFi. Seems that wake related to wifi is the main issue many times.
The problem is - when I have WiFi hotspot, good signal, got connection, but do not get network access (needs to be authenticated), all of that in background (no alert, no visible action on screen). So, on WiFi screen I can see connected, but actually I did not get network access, so all services which need network access (including Google services) are simultaneously trying to go to network, to get updates or any other data and - that is draining battery heavily - access to network is not existing.
Anybody experienced this? How to fix this issue?
So, connected to WiFi hotspot, very good signal, the WiFi is connected.
No network access (WiFi needs to be authenticated), all of that in background (no alert, no visible action on screen).
For example - trying to reach 8.8.8.8 - Google DNS does not work
Phone is rooted (just to say that - I may install any application that would be helpful, also, access to configuration files available).
What needs to be done? Which parameters are to be reconfigured?
How to control the number of attempts Android is doing from different applications to access network resources?
If I go into developer settings and switch off Mobile data always active (in an attempt to save a little power when the phone is on Wifi), I find the phone often doesn't enable data when I leave Wifi. I have to cycle airplane mode to make it do it.
Anyone else finding the same bug? Or even using this setting?
I've had dropped connection issues since day 1, with airplane mode being the only way to restore my connection. And this was with Mobile Data always active set to on.
Who is your Carrier??
Have you noticed similar issues even with mobile data always active?
When I go to building with no cellular and come back outside. The phone doesn't automatically reconnect to cellular, leaving me with no service. What a strange bug.

EE in the UK. Works fine almost all the time so far if I keep mobile data active.
Vodafone Romania, toggled the setting off in dev options as soon as I got the phone. Data switching works fine still.
Try going into the testing menu (dialer code *#*#4636#*#*), select phone information, select 3dot menu on top right corner, try switching around between Europe and automatic. I'm my case ,selecting Europe presented various weird connection issues , biggest of which was that the phone refused to connect to LTE unless I used "automatic".
