Data Connection issues?

I am wondering if anyone else has experienced issues with their phone taking way to long to establish a connection when surfing the internet. Some times when I click a link it will take for ever and sometimes not connect at all, of course when it does establish the link it is blazing fast. Typically when it cannot establish a connection I will just put my phone into Airplane mode and then turn Airplane mode off and typically after that it is able to establish a connection.
Thanks.

my phone often goes from good 4g reception to just showing two or three bars with no connection type (never auto switches to 3g, occasionally switches to 1x). just now it went from 4g to no connection type, so i dialed *#*#4636#*#* and tried turning the radio off and on, tried changing the radio mode to LTE only, cdma prl auto, and a couple of the other choices and it never seems to make a difference (always poor connectivity, sometimes total data drops, sometimes while tethering and sometimes when just using the phone normally). could just be LTE tower work in many areas, but im looking forward to an upcoming software/firmware update from htc or verizon.

Sometimes when I lose connection, I just restart my phone and everything works again. Try that and see if it helps!

I run into that quite often... sometimes it clears up after 20 seconds, others I have to disable and re-enable the data connection. I'm strictly in a 3G area, and it's done it with LTE on and off, as well as stock ROM and my custom ROM.

Really? A $500 phone and you're ok with having to turn it off and on to maintain a data connection?
I've had several HTC phones, going all the way back to my WinMo phone, and this Thunderbolt has to be the worst HTC phone I've used to date.
On my second device, if I keep it, it'll only be to grandfather the unlimited 4G data plan.
Inconsistent data connections and force closes up the wazoo... Wow!

Well, I've got the quick buttons in the dropdown tray in my ROM, so it's just as fast... still, its something that shouldn't be happening in the first place.

My dig wasn't at you, no offense meant buddy. I'm pretty much fed up with this device and will most likely return and cancel contract.
I've had issues with data since day one and I've never had so many force closes on one device.
This is Verizons flagship 4G device and it's a POS.
I've been on Android since G1, iterated thru the OS with each release thru to Gingerbread on my N1.
Verizon has a rocking 4G network, HTC released a crap phone that was delayed for several weeks. I would have thought that by the time they RTM'd it would have been fixed, or at least better than it is.

It's cool, I know what you mean but I'm liking the phone... Occasional reboots don't really bother me that much - this is probably because sprint wimax is nonexistent pretty much anywhere indoors and is the most unreliable network connection ever. the evo was a solid reliable device, but it was worthless because of the network and i canceled sprint to come to verizon for the thunderbolt. im happy with it despite a few annoyances. once i root and cm is released this phone/network combination will be untouchable.
i felt more comfortable using dialup and praying the phone wouldn't ring and disconnect me than i did using sprint wimax. their 3g is slower than dialup in a lot of areas at the moment, too.

This is driving me crazy also. My phone will constantly drop whatever connection it had (wifi, 3G or 4G) and just sit there with no data connection for a couple of minutes whereby I finally have to reset the radios and then wait while it cycles through 1X and then maybe 3G or 4G if I'm lucky. Or it just goes back to full cdma bars and no data connection. I don't have 5 minutes every time I want to check the internet or email to wait for the phone to reboot or reset radios or do whatever it's doing.
I had the EVO, and while the 4G wimax connection wasn't always stout, if you lost it you immediately grabbed a 3G connection that was solid. This delay/no data connection thing is making me think twice about switching to this phone. Love the 4G when it works, but it holds a connection way too infrequently for me to be useful, and I'm in LA where the service is supposed to be blanketed all the places I'm trying.

From 4g with full bars to 1x....

I just got my thunderbolt and my 4g keeps dropping.... Is there a problem?

Ever since the nationwide outtage a week ago my 4g has been spotty at best.
I have noticed slower 4g speeds on average and it drops alot more as well.

yeah, stop dropping it

I had the same problem after spending a weekend in Mexico - they replaced my SIM card at the store and it has worked fine ever sense.

I keep cycling through 3g/1X and the network is constantly unavailable, wtf is going on? Im so disappointed with this phone so far.
I dont know if I need to install a new radio? I installed bamfs remix 1.6 and some lean kernel, did I do something wrong? My Incredible never had these issues

Where do you live? That obviously matters, 4g coverage keeps expanding in Chicagoland area, I get 4g almost everywhere I go.

I live in Akron, I get full 4g bars then it drops to nothing, then 1x, then 3G. its unreal

Did you enter your address in the coverage map? Don't know how big Akron 4g coverage is, but again, I rarely ever lose 4g around Chicago and the burbs.

Unrooted BOLT, same issue with connection
I have been seeing the same about the connectivity being bad. I live in burbs of Philadelphia, only about 20 mins from city so i'm not going to pin it on my location..
So you are rooted? I however am not. Just got the thing and wanted to see how it was for a bit before rooting, but now i'm thinking before i root i better make sure the phone isn't crap or i'm not gonna be able to return it.
Ugh. Let me know if you're going to try and call VZ, HTC, or whatever. PM me if you find anything.

Mine is going up and down, as well as getting 3G or just bars in areas that should be 4G.
Another person in the office here, which should be good 4G, also having his phone do the same.
I'm rooted, he is stock.

Pretty much from Mid-County to the Lehigh Valley exit is still 3G in most areas but south towards the city and in the Lehigh Valley itself is all LTE. I travel down from Allentown to Philly regularly and I can tell you this from personal experience.
FYI Lehigh Valley LTE is down right now but I just got out of a meeting with Verizon (less than an hour ago) and they supposedly knew there was some maintenance being done in our area (so that may be the reason for the current outage.) If you switch out of LTE Mode to CDMA LTE auto you should pick up 3G (I'd also enable airplane mode and then disable it to pick up a strong 3G for right now.)
Oh and +1 on the rooted/non-rooted thing. You can flash back to non-rooted stock from a rooted state to send it back. Instructions are in the development forum.

Hi there, thanks for that info i appreciate it. I seem to be missing where htc allows us to switch btwn the 4g and 3g, i searched for the question but didn't get much results. So i'll my noob question right here. Where is that done?
I see under Settings > Wire & networks > Mobile network settings there is a System select option, for "Change the cdma roaming mode", is this where i'm supposed to be? Roaming doesn't seem to be the area i'd think to have to change this particular thing, but i don't see much else in these menus. Please advise or link a thread that i didn't see in my results.

Verizon has a problem with their new eHRPD network.. which is what the Thunderbolt is on by default.. (this allows for 4G + simultaneous talk and browse on 3G).. However, though 4G works OK, 3G doesn't seem to.
In order to tap into Verizon's original 3G network.. dial ##778# on your phone.. go to edit mode (you'll see pop up after you dial that number)..password is 000000 (6 zeros).. go to modem settings.. Rev.A and eHRPD is probably selected there by default.. choose "Enable" option... which will kick it out of eHRPD and then hit menu.. commit changes.. and the phone will reboot. You'll be on Verizon's original 3G network which will work fine.. but you won't have 4G.

I don't know about you but I still have 4g...

4g toggle and other questions

Ok, i finally got this thing rooted. I have a few questions about this, and these may be more ICS questions than Photon questions.
Do I have to do anything to turn on 4g? I cant find anywhere to do this. I liked the toggle buttons that showed at the top of older version of android, anyway to get those back? I ask because i was in an area yesterday where 4g service is available, but i never saw the phone automatically change to 4g.
Also, a program that i have used alot in the past is Roam Control. This is so that when i was at my hunting land, i could set my phone to roam only. I noticed more options in Preferred Network Mode. Is this how to set my phone to roam only? Because i installed Roam Control, and it doesnt work for this phone.

Check in development for the toggles. Still no 4G toggle. But rangerbry did an awesome job porting the others over.

In the mobile networks section of the phone there are options, in your case, "CDMA" or "CDMA/LTE". I would think if you leave CDMA/ LTE selected the phone will connect to LTE when it or IF it is available. If not it will simply stay on 3G/CDMA.
How did you know the area you wer ein actually had LTE? Sprint seems to be launching a market when there is like 20% coverage, so good chunks of an area will not see it light up yet on the phones.

not lte but 4g. i know because my other phone got 4g service there. It seems like if u leave this phone on automatic, its not actually automatic cause it wont pickup 4g. which option do i use for roam only?

Which other phone? Was it WiMax capable? This phone will only do LTE, not Sprints WiMax. Both are different forms of 4G for Sprint.

Would be really nice to have some way to toggle 4g on/off... I know my buddy's Evo3D (yes, wimax...) can easily toggle it on/off. He said his battery life is WAY better when he leaves his wimax radio off, and I would imagine leaving the LTE radio off would be beneficial.
As there isn't a whole lot of Sprint rollout for LTE right now, turning it off permanently isn't a bad thing... But if I'm traveling or just curious - it would be nice to have this toggle!

Yea, it seems like this is the only method right now. Just set the network to "CDMA" and it will only be able to connect to 3g. I don't see any change in the 4g status, any way to verify this?
I was actually surprised at how granular my buddy's 3vo was with 4g - it was almost like wifi, had everything separate (and this is stock...) So I'm really hoping we can sort out something similar - because I don't see how wimax and LTE are different in these respects - no?

Nah, as I suspect that unlike WiMax (which was a separate chipset) the LTE radio is combined with the CDMA radio on the chipset (and maybe even the GSM radio, if the chipset's advanced enough- I know there's combined CDMA/GSM radios).

That would suck. So far my battery life on this device is really awful... I've only been awake for 2 hours and I'm down 20%.

I don't know if you "got" your answer, but I was talking with a Sprint Rep and she told me that the LTE just "turns" on. It's kinda like Tmo's HSPA. It's part of the Network. It just switches over if it sees it.
In your settings, you can say CDMA or CDMA/LTE. That's asking 3G or 3G/4G LTE. As far as a toggle, someone needs to come up with it. LoL!!
Your best bet, until a developer comes up with the answer, is to make a shortcut to that. I want this phone. =.P

The issue, of course, is that having the LTE radio (which appears to be a separate entity, unlike GSM where it's merely another modulation scheme that the chipset understands) be on all the time drains power that's essentially being wasted since Sprint's LTE Network is largely nonexistent.
The reason for wanting a Toggle is for those folks who spend their time in non-LTE (or marginal LTE signal) areas, who'd like a quick way to either test for an upcoming rollout, or to use LTE only when in a known LTE-enabled area.

Yea. I completely understand that. That's why I also stated that OP should just have a shortcut to their setting where they can change from CDMA to CDMA/LTE. That way OP can turn off LTE when not using it. A toggle, of course, would make this process a whole lot easier. I don't see why there isn't a toggle. There's a toggle for 4G WiMax. It does the same thing. When it's not connected, it just idles and scans again. It uses more battery looking for 4G to connect to than actually using it. LoL!! I've noticed that 4G WiMax "sleeps" quickly once it connects. I hope LTE would do the same.
Let me stop before I start ranting on. LoL!!

I looked at them briefly....am I missing something or does the battery saving one not give you the ability to give parameters like syncing every 30 minutes/1 hour or the like? If the ability is there, I couldn't figure out how to edit that one properly. I only saw 3 options and the one that'd be closest to what I'd want basically read like it will only sync when you're actively using the phone. I want that, but additionally would like it to connect and sync periodically and shut data back off. I'd used Green Power Premium on my Epic for that but thought maybe Smart Actions would give me the ability to do away with using it.

[Q] Questions about This phone

Is there any way that I can connect to a wifi network without disabling the data network ? And is it normal for this phones to be really hot when 4G is on ?

No and no. The OS will use wifi over cellular data. If you just want to use cell data turn off wifi. Your phone shouldn't be "hot" when using LTE. Try getting a CPU temp app from market and report back how "hot" it is.

What do you mean by "4G"? On LTE, my phone is fine, but on H/H+ it heats up slightly.

Connection dropping

I keep seeing my 3g connection dropping completely. I'll be browsing the web and im not moving at all and all of a sudden the connection is gone. I first thought it had something to do with the connection optimizer but it doesn't seem like that. Did anyone else experience this or know a solution to that?

i noticed that this was happening when mostly when the phone was going back and forth between 3g and lte. so i changed the mobile network settings to cdma only instead of cdma/lte and it was much steadier.

So there is really no solution besides going to 3g only. But it really isnt jumping from lte to 3g . It will show 3g and all of a sudden nothing. Sometimes even showing me the little x over the bars.

This happens in an area with partial Spark.
Mine does same thing because I have 3 towers all equal distance from me. 1 is Spark other 2 are not.
If you travel to another location you probably won't see the issue but in short from talking to some eng. the phone is doing 1 of two things.
A) It see's an LTE signal and as LTE is primary it starts to try to connect to it but before it fully does (thus why you never see LTE icon) it realizes it doesn't support the switched fall back required to allow Spark phones to get calls while on LTE so it kicks you back to 3g. This process continues to repeat :/
B) The phone see's an weak LTE signal, as is primary starts to connect but before it fully does the signal is determined to be to weak and falls back to 3g.
In both cases the phone possibly would never show you the LTE icon as that will only show once fully established and it doing this jumping back and forth causes 3g to go and die where forcing CDMA fixes.
The other downfall to this is it KILLS the battery.
Connecting to WiFi won't help with the battery part either as it still does the jumping around.
Your only option is really force CDMA mode only when in an area like this, for me, this is at home only, or live with it and lower battery life until they upgrade the towers all the way.

Thank you for the detailed explanation. I just got off an hour long phone call with sprint with them trying to explain me my phone is defective and my wifes as well. Then when i told them it isn't they started going into the "Yeah its our network" mode but then came back saying she put a ticket in for me and my wife to get the phones repaired. I told her I don't want that to stop worrying about the phone and to send me an air rave. Problem at my house solved lol. They are sending me an air rave

Thank you for the detailed explanation. I just got off an hour long phone call with sprint with them trying to explain me my phone is defective and my wifes as well. Then when i told them it isn't they started going into the "Yeah its our network" mode but then came back saying she put a ticket in for me and my wife to get the phones repaired. I told her I don't want that to stop worrying about the phone and to send me an air rave. Problem at my house solved lol. They are sending me an air rave

You could try turning off or on, depending on whether you have it enabled already, connection optimizer

Hate to share the news but that won't solve your problem, it actually could make it worse as it's now another signal to bounce between.
4G IS always priority when enabled, so regardless of you having a "tower" inside your home now, that does not provide 4G, so if the phone's seeing one that does which is what's causing the problem your issue will remain the same meaning you're forced to put the phone in CDMA only mode still.
The problem isn't with the 3G tower or 3G signal, the problem is the 4G signal being detected but not yet compatible with SPARK due to missing the circuit fall back feature, which the phone doesn't know until it attempts to connect. In some areas where it's partially setup the phone can connect to 4G and just calls won't work, in other areas it's disabled or doesn't exist and this problem happens.
Your solution will simply need to be put the phone in CDMA only mode when in a troubled area only, or just leave it in that mode and have no 4g until everything is upgraded better, or deal with as is.
