Curious issue with my Titan II. Cellular data connection just fails at random intervals. Cycling airplane mode or rebooting the phone is the only way to get it back. HTC blames it on AT&T and AT&T blames it on HTC. I've spent hours on the phone with each. Even got a new Titan II from AT&T, but it went into this constant reboot loop, so I went back to the first unit.
Now comes the interesting part: I live in Detroit and have been traveling to FL quite a bit, this year.. and the issue DOES NOT HAPPEN IN TAMPA. Phone runs perfectly well, there. Here in Detroit, cellular data "up" time ranges from 5 minutes to 14 hours when static. 2 minutes to 20 minutes when driving around town. Drops are less frequent when streaming something.
HTC Titan II stock (FW: 2180.0400.118011.502)
Windows Phone 7.5 (7.10.8112.7)
4G SIM card (3rd one)
Appropriate data plan
Serious thanks for any ideas anyone has. Do I add an APN, throw the phone against the wall, or what? Please do not suggest I change to a different phone as that is not an option.

Yes, I'm facing the same issue.
It seems something related to wifi sleeping when the phone goes stand by and the solution could be keeping it alive in some way....like streaming..
I hope this will be fixed with AT&T Tango 8773 Update (Once it finally come....)

Are you sure you aren't hitting "black spots" on your network? If you have random connection drops in only particular area it is likely the masts and AT&T issue. I've swapped my provider from the one which did 2G/3G signals to 3G only provider. 3G only has better coverage and lesser black spots on the network and hence I hardly see any drops in connectivity. Don't hard reset or anything, it will only make you re-do the whole phone, won't help the cause.
Have you checked if two golden pins on the back cover are making good contact with phone?

Have to rule all of that out as it doesn't happen at all in Tampa. I can drive from Ybor City to Clearwater and back and never need to reset the phone. Here at home, I have four bars and will lose cellular data with the phone in a static location. Driving around in Detroit is guaranteed to make it drop cellular data even with the phone lit up and active. I can have Navigator running and it'll just quit loading maps and giving directions until I cycle Airplane Mode. In Tampa, this doesn't happen.
In Tampa, I've gone the whole week without any need to reset the phone. I can't walk from the gate to baggage claim in Detroit before it loses its data connection.

UPDATE: Cellular data connection is a little better with WiFi turned off. It won't lose it as quickly in a static location, but still loses it as I move between towers. Also had to reinstall a couple of apps that had stopped launching.
Is forcing Tango an option?
I have the same problem,
I live north of detroit.
my phone has been in to htc repair 3 times, i think they have replaced every part in it, the last time i got it back it held connectivity for 11 minutes.
this is on my home tower as well as several towers around me.
Normally all testing was done with wifi off, on towers where the lumia 900 and my wifes iphone have never lost data.
i have been waiting a week for a htc level 2 rep to call me.
we shall see
Keep me posted. Last time I spent time with HTC, they decided that - since the issue only happens in Detroit - that it was AT&T's problem. AT&T, naturally, claims that the problem doesn't appear on any other device, so it must be the device.
Can't wait for Windows 8 phones. I'm getting one.. ANY one.. the first day they go on sale.
Well I just got off of the phone with a level 2 rep from HTC, who seemed pretty confident that the problem is the rear cover. He is sending one out, and says if that doesn't fix it then it will be a phone replacement.

I'm more skeptical than you, trust me, but it would explain how so many people get the same problem with replacement handsets, as that piece is often not replaced
So, I'm in Florida for the week and noticed something.
In Detroit, the status bar says "4G"
In Tampa, the status bar says "LTE"
As before, I have not lost cellular data connection since I landed in FL. Kind of rules out the battery cover as the issue is gone, here. It appears the issue goes away in LTE areas while it's present in areas yet to get LTE. Detroit's LTE rollout hasn't happened, yet. So, it appears I've got another month of suffering before the problem is rectified.
One other note. With Internet Sharing set to ON...
In Detroit, my wife's laptop connects to the phone and can get internet.
In Tampa, my wife's laptop connects to the phone, but cannot get internet. It gets the error msg: "your computer is trying to use a dns server that is incorrect or doesn't exist"
My laptop works flawlessly connecting to the phone's Internet Sharing both in Detroit and Tampa. For the life of me, I can't find anything different in her settings over mine. Both are Win7. Hers upgraded from Vista, mine x64 and new this fall. Also, two internet-capable televisions connect to the phone and get to the internet flawlessly. But something with LTE doesn't like my wife's computer. Odd.
Honestly, I adore everything about this phone except for the data connection issue in Detroit (and a few other areas, it seems).
There HAS to be a setting or SOMEthing I can tweak to get this thing to work in Detroit.
Check battery cover, radio negotiation, firmware of radio

Hum.. that's curious. I had the original titan with similar issues.
I disabled wifi when not connected. I replaced battery cover also. The titan2 supposedly fixed that issue with the battery cover because it was a design flaw.
The radio supports 2G, 3G/4G/H and LTE. You may want to check it. You can set the radio it uses and not let the firmware decide which radio to use. You can check the service menu, I forgot the code. Just search for it.
If you use 2G, data and voice are not supported simultaneously. Check and make sure the contacts on the battery cover and on the phone are clear of debris. Use a solution to clean the contacts on the phone.
In the past I manually set the radio to 3G (HSPA and HSPA+) [HTC Pure, HTC HD2 on at&t]. The 3G radio is mature and should have less issues with the radio negotiation.
BTW, there is a keep alive wifi app also.
Thanks. I'll have to look for the codes. It's pretty obvious after going back and forth so much that the Titan II has a flaw with the way it handles AT&T's 4G. Scanning the maps from others who have had problems all show that they're in areas with 4G but without LTE.
Yeah, if I could force this thing to do LTE or 3G I think we'd be fine. It's the Best Phone Ever so long as it gets LTE, 3G or Edge. Anything else and it's crap.
Yes, back connector is okay and I've done this every way one can think of and kept notes. WiFi doesn't matter. On or off, the T2 will lose cellular data connection randomly in 4G areas. NOT in LTE areas. I'm only unable to test it on other carriers.
Similar problem with data
So I have had a similar problem -
I had a Samsung Focus, great phone, but I wore out the USB port - wouldn't charge consistently or sync. I figured I might as well use the insurance I had been paying. They sent me a Titan I - it had the bad microphone issue. So after some messing around they sent me a Titan II.
It has never had consistent data connection. I am in an area where I get the 4G icon (not LTE).
My experience tells me that if I move around and change cell, or lose signal in the cell I am in for any reason, then the phone will NOT connect back to data. It can (almost always) still get phone calls and send/receive texts and so on, but no data. Toggle airplane mode always fixes the problem, until the next time.
Originally HTC wanted to send me a new back cover - AT&T have been completely useless, they have no idea. Eventually after messing around with factory resets, powering on and off continuously, another new SIM card, HTC decided they want the phone repaired or replaced (level 2).
It is still inside the 30 day limit for exchanges from Assurion (AT&Ts insurance carrier) so it's getting replaced. I'll let you know if it fixes the issue, but I haven't been in an LTE area so I can't check that.
Personally I think it is a problem with handing off/reconnecting to 4G tower service - we'll see......
Anyone have the radio codes?
I've had the same problem since I got the device as well; but have noticed that it doesn't happen in all areas around me. My house is one of those areas though that I always lose connections. I've tried every APN / idea I've found on the internet with no luck. It's clearly something to do with AT&T towers. The only think I've not been able to try is a different SIM card in the same phone since it requires a '4G' sim card to even work at all. However the same SIM does work fine in '3G' only phones.
Going with the radio idea, does anyone have the codes to turn off the LTE radio? I just saw the list saying this phone will be long gone before AT&T ever gets LTE in Colorado so maybe just turning it off would help. Every code i found was for the T1 though and it didn't work on my phone.

UPDATE: HTC insisted on sending me a new SIM card cover (since it contains the radio's antenna). Despite my argument that the fact it works in Florida negates antenna as a suspect, they sent it along, anyhow. Naturally, there is no change. It still randomly drops cellular data. And now, I've picked up another spot on the freeway where my calls get dropped. Granted, it happened ONCE, so that could be any number of things. Long story short, it's not the antenna.
Next idea?
Well, I'm in Florida and found a spot where the phone fell back to 4G from LTE. Data issue returned. So, that takes geography out of the equation. The phone can't hold a data connection when using 4G. So, should I go for a fourth unit?
My addition:
AT&T recently rolled out LTE to my area in CT. I never had the problem before on straight 4G. Now, when I go from LTE to 4G (my drive every morning) data just stops working. I push it in to airplane mode and back out again and it works.
BTW - I am running Tango, so that is not likely to be a fix unless a radio update is released with it.

AT&T just switched on LTE metro-wide, last night. Now, the Titan 2 performs just as it does when I'm in Florida. It's nice having a data connection that'll stay good all over town, again.
I have spent some time discussing this with HTC and AT&T. Actually just got off the phone with HTC level 2.
I too have gone through all the options - new phone, new cover, new SIM card (you can just go into AT&T and ask for one, no charge), hard reset, everything.
From the information in this thread, and elsewhere I can say that the phone drops data on one of two things happening:-
- connection to tower is interrupted in current cell, but is re-acquired
- connection is handed off to adjacent tower as you travel to a new cell
Both these things will drop data IN 4G AREAS ONLY. If you are lucky enough to have consistent LTE in your area, you shouldn't have any problems.
Right now I'm working on getting the service menu codes so we can play with the radio settings. It sounds like HTC support reps have been forbidden to give these to end users on windows phone devices (I wonder why??!!).
If I get this information and it provides a fix for this issue, I will (obviously) post it, and I imagine HTC will as well. Here's hoping.....

Hi All-
Pre-TL;DR: Got rooted S4. NOT USING A DLINK ROUTER. All wifi networks disappear and reappear 'randomly'.
So I got my S4 from Verizon on Friday the 24th. I set it up and went on my way. About two days after I got it I noticed 'slow' download while on the wifi. Didn't matter what I was doing; google play, downloading a game's extra data, or even just sitting there doing nothing. As I looked into it I found that my wifi connection was dropping. I'm not talking about disconnect and reconnect, but wifi in general would drop. I verified this while sitting in my living room. I live in an apartment and there are a lot of neighbors with wifi. While looking at the available wifi networks I noticed every few seconds ALL of the available networks would disappear (showing only my saved networks). I used a wifi analyzer and changed my wifi channel to an unused channel, checked for firmware updates (both router and phone), but nothing changed. On Tuesday I started work after the holidays and decided to test the wifi on my companies guest wifi. I was seeing the same stuff happening at work. I don't think it's my router(s) because all wifi goes away, not just the specific wireless network. I have the stock S4 that has been rooted using open1your1eyes0's guide
[GUIDE] Root for Verizon Galaxy S4 ***Updated 5/27 - 2:30 AM***, however I noticed this before I rooted it. Is anyone else having this problem? I'm about to take it to Verizon on Thursday.

I experienced this problem on Saturday when I got the phone-Called Verizon and was transferred to Samsung-they told me this is a known issue in the phone and it will require an antenna swap to fix. Apparently they have fixed the phones they are manufacturing now, however the ones which were initially released all have this problem.
Vzw has been no help at all in resolving this, and pretty much have told me "too bad, so sad". Really crappy of them.

Nghthawk and Fleury, I was so happy to see your posts!!! So it's not just a firmware issue!!!
I have a non-rooted S4 and have the same experience. I was with T-Mobile for a week before I transferred to Verizon and had the exact issue there. (I have a co-worker who has a Sprint S4 that doesn't have this problem.) I have this issue both on my home router (Linksys) and at work (Motorola). Previously, I had an S2 and never saw this issue once, neither at home nor at work. I also spoke to Verizon who told me to talk to Samsung. Samsung (via email) has had me try all kinds of crazy manual WiFi settings - none of which work - or are at all practical...
I'm still within my first 14 days of signing with Verizon, so I can still jump ship to get rid of this phone. I'd really rather not spend another __ hours setting up another one, though.
Perhaps you could help me with a bunch of questions I have - please... I really need help with this...
1. Who told you that the antenna needs to be replaced - Samsung or Verizon?
2. Is that documented somewhere that you know of?
3. Is either Verizon or Samsung going to cover the antenna swap?
4. Who / when is supposed to do that for you?
5. What do you suggest I do in my situation (e.g. being within the first 14 days)?
6. If it's an antenna issue, would that affect voice calls (quality / dropping), as well?
Thanks so much!
Eliezer
I will try to answer your questions as best as I can...
1. Who told you that the antenna needs to be replaced - Samsung or Verizon?-Samsung repair rep
2. Is that documented somewhere that you know of?-I'm sure Samsung has it in writing, Verizon is still in denial-having talked to their executive offices today-to which they are clueless and a waste of time
3. Is either Verizon or Samsung going to cover the antenna swap? Yes!
4. Who / when is supposed to do that for you? Samsung told me to send it now, however I am traveling and can't do that at the moment
5. What do you suggest I do in my situation (e.g. being within the first 14 days)? I would keep the phone, they will get it fixed, they don't really have a choice, approx sales are around 80 million units-they can't just ignore it-plus we are going to be the first to get aws spectrum...
6. If it's an antenna issue, would that affect voice calls (quality / dropping), as well? I have no problems with call quality, in fact, it is far better than my Galaxy Nexus which I traded in to get this. I have had 4G also act up to where it just freezes and fails to deliver internet, even though I will show 3-4 bars as well as the 4G lit up....So I believe it seems to only effect data.

It would be useful for those of us still on the sidelines if we can determine if we are getting a fixed version or one with this problem still.
This is one of the reasons I didn't jump in yet - to wait out any early production issues. Well, and still hoping for a 32 or 64gb version.
Interesting. I have a lot of the same issues. My WiFi is so bad I can't see any other WiFi networks on my device from my house where my other devices see 5 to 6. If I go into my daughters room my WiFi pretty much drops completely every time.
I just got off the phone with Samsung tier two / advanced tech support. He told me that my phone was manufactured May 15th... If a two week old phone has the problem, I cannot imagine the "new" ones don't also... He said they have no known issues submitted by Verizon for WiFi connectivity of the S4. Due the fact that it can connect to WiFi, he didn't think it sounded like a hardware issue. He suggested testing by taking the password off my router and seeing how it holds the signal. He said if it was able to maintain a connection like that, it must either be the router firmware or phone software issue.
Verizon said they could swap it with a new one for me - but there's no guarantee (or reason to think) that the same thing won't happen with that new one. And the option of sending it to Samsung and not having it for 11-12 business days isn't very appealing, either...
Not so happy about this...
Eliezer
you do know that the WiFi isse with DLink routers (DIR-655 and DIR-855) is not restricted to only those routers right? It does exist with other brand routers from whats been written about it.
Point being i have a DIR-655 router and had the connect drop connect drop issue and all I did was uncheck the WMM option and rebooted my router and its rock solid. WMM is kind of pointless, 95% of ppl can't even see a difference using it. I don't even think any of the public access points i've run into even have that enabled either.
If it's just your home wifi your having an issue with, turn off WMM in the router settings if you haven't already
Any updates about this? I'm experiencing wifi issues with my S4 where the signal I get on wifi is just horrible. Finally went into work today where we have an open wifi network on the entire campus, and I can't even get 2 bars of wifi from my desk, where my Galaxy Nexus would get 4. When it does connect, it's horribly slow. This has got to be a hardware issue. I may bring it back to Verizon, but I'm wondering if they will even believe me and swap the device.
Well, since I originally posted on this thread - and had commented that I saw this issue on both Verizon and T-Mobile - using both Motorola and Linksys routers --- I've switched to AT&T. I got one of their S4s and have had rock-solid WiFi connectivity with those same two routers ever since...
Not sure what to say...
I experienced my WiFi dropping like that once... how ever.. never again... really weird.. I have better Wifi then I did on my last phone.

Which carrier are you on?
Just compared to my friend's S4. With the two S4's sitting next to each other on my desk, he gets 4 bars of wifi at -46 dbm in Network Signal Info. I get 1 bar, and -88dbm! I walked directly the nearest ceiling mounted access point and my signal went up to -71dbm while he went to -40. So yea I definitely have some issues.

Not from what I can tell. I can edit the post, but I think a mod has to edit the title.
Update tho to my op:
After a factory reset and a re-root I noticed that this issue had stopped. It happened one more time after that, however, after a reboot it was fine again. I have yet to run into the problem again. This leads me to believe that there is a software issue (would also make sense why only Verizon phones seem to be affected) and not a hardware issue. I heard that google is going to release a 'clean' version of the S4 rom when they launch their carrier-less S4. I may just wait till that phone is released and flash that and see what happens.
I'm flashing mine to stock and doing a factory reset right now. Hoping it fixes the issue for now.

you do know that the WiFi isse with DLink routers (DIR-655 and DIR-855) is not restricted to only those routers right? It does exist with other brand routers from whats been written about it.
Point being i have a DIR-655 router and had the connect drop connect drop issue and all I did was uncheck the WMM option and rebooted my router and its rock solid. WMM is kind of pointless, 95% of ppl can't even see a difference using it. I don't even think any of the public access points i've run into even have that enabled either.
If it's just your home WiFi your having an issue with, turn off WMM in the router settings if you haven't already

I wanted to add my own experience. I have a Verizon Galaxy S4 -- SCH-I545. I managed to fix the disconnection problem by using a static IP address on the phone side since the work router serves up the same one to my device every time, so I'm not causing collisions (and I don't have control of the router at work). I was getting 'failed to get IP address' messages when the connection dropped. See here:

However, reading other posts about the antenna issue, I'm starting to think that it might just be that. I'm about 20 feet equidistant from 2 wireless routers at work, and using the *#197328640 hidden menu, then Menu button, then WiFi, my RSSI goes from -68 to -74 and goes up to about -52 to -55 when I'm about 3 feet from the AP I'm associated with. Does that seem low? According to what I've googled it seems like it is low...

And to think I was about to give up on contacting Samsung because they refused to acknowledge my Bluetooth issue here:
http://forum.xda-developers.com/showthread.php?t=2304828
With the BT issue I've done extensive troubleshooting and pretty sure it's not a software issue (at least not other apk's interfering) but possibly the bluetooth implementation or drivers itself.
:sigh: Now I'm going to have to test with the other S4 to see I get the same WiFi signal strength, at least at home, anyway.
So update for me, took mine to Verizon and they swapped it out. This one gets a great wifi signal.

Judging by your earlier numbers mine is fine. I compared it to an S3 and another Verizon S4 and both have about the same RSSI +/ 5 of each other at the same point at home... so the issue I'm facing is probably just related to the router at work I have no control over.
Well, it took me long enough to figure out that the Verizon S4 has its own completely separate set of subforums from the International and AT&T versions.... No wonder I got no responses to my post over there. So, I'm reposting it here:
From yesterday:
My brother and I both got S4s almost 2 weeks ago. He upgraded from an S3. Me from a Rezound. He also has a work phone that is a Verizon Note 2.
We were out at our parents' house over the weekend. Our dad has a RAZR Maxx and a 4G Verizon MiFi for his house. All 5 of these phones/devices are on Verizon.
Both of Dad's devices and my brother's Note 2 were maintaining a steady 4G LTE connection. The Note 2 only showed about 2 bars, but it held it steady and never dropped back to 3G at any time while we were there.
But, both my and my brother's S4s would not hold 4G. We played around with network settings. Changed them from CDMA/LTE to Global, and then back. They would both occasionally switch to 4G for a minute or so, then always switch back to 3G.
I called Verizon tech support and they walked us through things including turning off the phones, pulling the SIMs and letting him push a new PRL to us. Nothing helped, so he told us to go get new SIMs. I did that yesterday and went back out to my dad's and it's still the same. My dad's phone and his MiFi maintain a steady 4G LTE signal and my S4 mostly just stays on 3G.
I also noticed that I went to the movies yesterday and when I was in the theater lobby, which is right in the middle of town, where there is strong 4G signal, my phone had dropped back to 3G there, too.
I'm still within my 14 day return period and I am seriously thinking of returning the S4 and getting a Note 2.
Does anybody have any better suggestions?
*********** then, yesterday ***********
I found a thread on the AC forums where a guy reported the same issue I'm having. He took the SIM out of his Rezound, cut it down, plugged it in, and he said that fixed his 4G reception problem.
I'm going to VZW after work and trying a 3rd SIM. This time, one of the old style, that doesn't support NFC.
*********** then, today ***********
I went to Verizon after work yesterday and got a new non-NFC SIM. Then went back to my dad's house. The SIM does not appear to make any difference. My phone still wanted to switch to 3G and stay there.
But, I did figure out one encouraging thing. I used Battery Monitor Widget to get into the Testing screen. There, I was able to change the phone from "CDMA/LTE (Auto PRL)" to "LTE Only".
After doing that, the phone went into 4G mode and stayed there, and actually worked fine. I turned on my hotspot and connected to it with my tablet and surfed for a while, with no issues.
This tells me that the phone's LTE reception is pretty much just as good as the Note 2 and other devices I mentioned before. It's just a software issue that is switching it to 3G mode when it doesn't need to.
I have a very odd problem with my Galaxy Tab 10.1 LTE (SCH-I905) which have not seen described anywhere that I hope someone can help me with. I am no longer seeing any signal bars instead the area has an x on it. Despite this I can use the Verizon Network and the 4G icon appears. When I look at the strength of the signal it say it is -120. This seems mainly cosmetic since I have always been able to use the 4G network and the speed seems normal. I am able to watch videos without any problems.
I cannot relate this to adding any app to my Tablet. My tablet is now rooted but I am running stock ICS 4.04 on it. This did not change when I rooted the phone. I tried removing most of the recent apps that I have added but this makes no difference. It seemed like this happened periodically before the phone was rooted. It worked fine immediately after I rooted the phone but a couple of weeks afterwards I no longer can see any bars on the cell signal meter, only no bars and an X.
Thanks for your help.
Regards,
Michael
I had the same issue with rooted stock 4.04. The bars would only show when I was in 3G coverage and 4G icon would show with no bars when in 4G coverage.
Still have the problem with Infamous 1.8.0.
I've had the International HTC one Max for about 4 days so far.I've noticed extreamly bad Wi-Fi reception. In places where my old Razr had 2-3 signal bars, I can't even connect to my wifi. While standing right next to the router I have about 3 bars, and I have more when I turn the phone around the other way. I've turned of WiFi optimization, factory reset my router and phone, even got a new router. I need some help with getting the WiFi to work. Any tips will be helpful. I'm running stock, unrooted sense 6 with android 4.4.2. Any easy way to fix this?

The fact that you reset the router, bought a new router, and reset the phone, leads me to believe its a hardware issue with the wireless card in the phone. To test this, can you connect to other wireless routers say at a coffee shop or friends house?
After playing around with my phone for a while, im pretty sure its fixed. Not sure if it was s-off that helped, or taking the phone apart.
