How I got my signal fixed

My problem was so bad - I was missing almost every incoming call, but instantly get a voicemail notification. Texts would come in once or twice a day - in large groups. After my phone working fine for 4-5 days I thought for sure, hardware problem. I hadnt rooted, reset to factory, update prl/profile (Through update and *2) etc etc .... no luck

Call and talked with CSR and techs etc for 3 days or so, with no luck. So I take it into my local repair shop - the lady took maybe 15 minutes with my phone, and told me something got hung up initially with the provisions. (Even though it worked fine for days)

So she reflashed software/reprovisioned my phone and its been golden since. Seems that "reactivating" the phone did the trick!
[Sprint HTC EVO 4G LTE] PsiPhiDan:
Any idea if this can be done without going to a tech shop? I am often getting voicemails with no call. I have an Airave on the way because of this issue, but I'm not 100% sure that's the problem.
[Sprint HTC EVO 4G LTE] Traceamount:
In the very least I'd imagine you would have to call in. Or maybe if you have an old phone, do the automated switch thing on Sprint.com to activate your old phone's ESN then reactivate your LTE? However if you make the appointment before you go in, shouldnt take long.

I don't work for Sprint obvi, I have no idea if that would work. But I do know her "reprovisioning" my phone fixed it, and Im getting 1.5 - 2MB speeds on 3g again now <3
[Sprint HTC EVO 4G LTE] TaintedByte:
I re provisioned it myself and only had the issue once since, I'm trying it one more time on stock and see how it goes for the next 24 hours. It has been great the whole day though which is awesome.

Yes. However, I don't know if this is how Sprint does it so ultimately you might want to take it in anyway (like I'll be doing it if this doesn't fix it this time around):

1. Get your MSL code, follow the guide found here. Note that market apps to find MSl codes don't work for HTC phones.

2. Open dialer and type ##786#

3. Touch Menu at the top right then hit reset and type in your MSL number when it asks for a password.

4. Hit OK but note that this WILL wipe your data. This is a factory reset. It will make the phone exactly how it was the moment before it was opened at the shop. SD card and internal card content will be fine.

5. Hope it works :) Ultimately, take it back to Sprint, if you're still within 14 days you can just demand a new phone.

I've also noticed poor reception with the new phone. I stream Pandora in the car to and from work. It drops out and the signal is lost far more often then my OG EVO ever did. I also find it roams more often then my OG. Only 3g on the ride. My luck i return the phone and a week later there is an update that addresses this.
[Sprint HTC EVO 4G LTE] Zameus:
Experiencing the same thing here. My GF and I have a long commute to work and usually after work she will stream netflix off my phone for the duration of our commute. We've noticed that streaming with the EVO 4G LTE, waaaaaaaaaaaaay more frequent buffering is occuring. I've also noticed slower 3G speeds at locations where my OG EVO would get faster service. Dissapointed indeed, but hoping a sw update will fix this. Returning it for a new one, I doubt will fix the issue if all these new phones are coming off the same manufacturing batch. I'll wait it out for the next update. I'm sure one is on the way.
[Sprint HTC EVO 4G LTE] mtg981:
I have had the OG Evo since it came out, so like many of you I am comparing the LTE 3g speeds to my OG. The difference is very noticeable-the OG Evo had WAY better 3g speeds in bad reception areas. But, in town where towers are most likely to be, my LTE will be much faster on 3g.

Like many of you, I to do not want to give up the features of this phone by taking it back. Do we think prl updates can fix this, or is it because of (as one poster said) the antennae is just crap and nothing will fix it?
[Sprint HTC EVO 4G LTE] ausch30:
This is a copy of a post I made in another thread several days ago:

Left pic is my old 3D from a couple weeks ago, right is my 4G LTE from just now. The top 2 results in both are while connected to my airave. Tests were all run at home, around the same time of day and connected to the same server.

I can't believe the difference in speeds between these phones but I really hope they do something to fix it soon.
[Sprint HTC EVO 4G LTE] massiveian:
I honestly believe it is the antenna that is causing the issue. This phone is thinner than the OG Evo so they had to redesign the antenna to fit in it, and because of that it may well be weaker than the OG. I dont think a software update would help at all. They could try boosting the reception but then i figure the battery will drain much quicker.

Maybe they will revise the antenna in later hardware but that wont be of any help to us who are stuck with the phone we have now
[Sprint HTC EVO 4G LTE] secondtwiggy:
I had the same issue with it suddenly dropping data and reconnecting every so often. If you are having that problem, switch to 'CDMA Only' in the mobile network settings. Mine has been a LOT better since I did that.
[Sprint HTC EVO 4G LTE] thenags:
I'm having horrible 3G issues. I'm constantly drop 3G at my two jobs where I NEVER had an issue before with my OG Evo
[Sprint HTC EVO 4G LTE] ausch30:
I got mine on 5/27 and I've had it set to CDMA only since day 2 with no difference. I even get warnings about accepting roaming periodically while trying to make calls. I even have an Airave and I got that roaming warning earlier today in my house. I think there's something wrong with my particular phone. I called customer service a few days ago and they reset some stuff with no change. I went into a corporate store yesterday and so basically removed my phone from the network and then put it back on. The funny thing is my speeds went over 1Mb for the first time immediately after she did that (I ran speed test right after she did it), but as soon as I walked out of the store I ran it again and my speeds were back to where they were, and they've been there since. I just ran it a couple times about an hour ago and I got 0.05Mbps and 0.12Mbps. I'm really starting to think I just have radio issues with my particular phone, problem is (which they told me yesterday) since the phone is so new their techs can't test the radios yet. I might return it to Best Buy in the next couple days.
[Sprint HTC EVO 4G LTE] mtg981:
I did that. I did that, it will help with "dropping" issues, but not with just plain "slow"service-IMO. I think that will automatically change back to cdma/LTE when you do a pro(or profile) update. Can't remember which.
[Sprint HTC EVO 4G LTE] massiveian:
Here go my speeds from today. This is at home in my house where i would normally have 3-4 bars with my OG EVO
[Sprint HTC EVO 4G LTE] secondtwiggy:
Switching mine also helped with speed...but I dunno if that's a fluke or not...
[Sprint HTC EVO 4G LTE] massiveian:
EDIT: I live about 1000 feet from a tower. My speeds should be much better than this
[Sprint HTC EVO 4G LTE] ausch30:
I agree, and I shouldn't go into roaming while I'm at home connected to my Airave. I was just thinking of the fact that every single review I read on this phone said it's a great phone on a crap network. I'm starting to think it's less the network and more the phone itself. I have seen statements from people on here though that say their speeds are better with this phone than the 3D or OG. I don't know, I do know that seeing your speeds makes me feel worse about it though. I was hoping it was an isolated problem and getting a replacement might fix it. I'm not so sure anymore, I guess it couldn't hurt though.
[Sprint HTC EVO 4G LTE] wfrandy:
Sounds to me like some of you are having the same problem my first phone had. It was very slow on 3g and would constantly drop data connection. I called sprint support and they had me reset the phone, which resulted in it failing to get a data connection at all. Ultimately, they conceded that it was a defective phone and they sent me a replacement.

On the up side, the new one has no problems with 3g speeds or data connections. Unfortunately, it does intermittently have the proximity sensor issue some others have reported. I will be keeping it for now though, hopefully their will be an update to fix the minor proximity sensor issue.
[Sprint HTC EVO 4G LTE] regulator207:
Get msl.

Type *#*#rtn#*#* in dialer

Hit menu, and select reset, enter msl and reboot.

This method does a full wipe including your provisioning data.

So when phone reboots you will get the activation screen. Just let it sit there and reprovision your phone.
[Sprint HTC EVO 4G LTE] ausch30:
I've dealt with Sprint twice now and they've done that both times, no change. Just as the person stated above your post, when I called and they did it I had no data at all for a short time. I rebooted and it came back but there was no improvement in speed. I'll probably call them tomorrow again about it. I'm just wondering, since I bought it at Best Buy, would Sprint replace it or would I have to go through Best Buy?
[Sprint HTC EVO 4G LTE] fastamx79:
In response to the airave, I have one too and my LTE would do that too (go into roam). In fact the first day or two I had the phone it was going crazy with my airave. I ended up just doing a bunch of power cycles to the airave, and now my roaming issue while connected to it have now gone. I also ran into this issue when I first got the Airave with the 3D, and after with the 3D after I transfered it to my wife. I'd say try that
[Sprint HTC EVO 4G LTE] massiveian:
so I provisioned my evo 4g lte using my MSL and here are the results from speedtest.net....not much better
[Sprint HTC EVO 4G LTE] ausch30:
Never had an issue with my 3D with it. Actually up until this point it's been absolutely great except for the random times it ends up text bombing people. I've power cycled it almost daily since getting my phone. Not for the reason you're saying but to check my speeds without the phone connected to it. I've had it unplugged and plugged back in at least 8 or 10 times since getting this phone.
[Sprint HTC EVO 4G LTE] KERKEDAGAIN:
How many of us with this issue are in areas where Network Vision is set to deploy..I'm in Houston and am chocking it all up to that. If after LTE/NV is deployed and I'm STILL having this issue..there's gonna be some furniture movin' up in this joint!!
[Sprint HTC EVO 4G LTE] ausch30:
I don't even have WiMax, I'm not getting LTE for quite a while. I'm sure it's not a tower issue.
[Sprint HTC EVO 4G LTE] fastamx79:
Guess it is one of those YMMV issues. Figured I'd throw it out there since it cleared up my roaming under the airave issue.

On a side note, glad to know I'm not the only one with the text bombing issues. LOOOOVVVVEEEEEEEEE when that happens :rolleyes: I think my record so far according to one of my friends was 37 messages at once :eek:
[Sprint HTC EVO 4G LTE] ausch30:
Lol, yeah. I tend to feel really bad and somewhat embarrassed when that happens. I figured out how to limit it though. I always wait to see how long the message takes to send when I'm connected to this thing, if it takes longer than normal I delete the message and immediately reboot the phone. This has limited it to 2 or 3 messages instead of 30.
[Sprint HTC EVO 4G LTE] fastamx79:
Good tip for that! I usually notice if it is taking longer than normal and the activity light is going crazy that it is in "full attack mode" Most my friends/family understand now and give me a hard time more than anything.

I've never tried rebooting the phone and deleting the message. I just unplug the box and let the phone finish up, count to 30 and plug it back in. But even that doesn't help because after the box reconnects it finishes its attack with an addition 5 or so messages :D
[Sprint HTC EVO 4G LTE] gavia11111:
I've been through 4 EVO lte's and not been able to receive any calls. Been through multiple resets, activations all with no luck. I have noticed that I can get calls if I'm on the phone (i can call out) already (call waiting). Signal strength for me seems much much worse then my og EVO. Probably going to give up on this phone soon. I have a feeling its a design fault. I really like what this phone offers and want it to work as I guess I thought it would. Biggest thing for me is not being able to receive calls. Sprint seems surprised about this each time I call. Not much knowledge base on this yet.
[Sprint HTC EVO 4G LTE] tmuka:
Fwiw, I had the same issue where I wasn't receiving incoming calls. I finally followed the programming instructions from Sprint.comhttp://support.sprint.com/support/a...e-gz982789-20120530-203901?&INTNAV=SU:DP:HDIB a few days ago for programming a used phone and now incoming calls work! You will need your msl code to try it...
[Sprint HTC EVO 4G LTE] quarkburger:
I saw a video of the One X on AT&T's LTE network. It reached about 16Mbps d/l and 7.6Mbps u/l. Should we expect the same on Sprint's LTE network with the EVO 4G LTE?
[Sprint HTC EVO 4G LTE] thenags:
Damn.. Just went a whole night without getting any texts which I thought was weird. Now at 6am like 20+ came through from throughout the night. This phone BLOWS for reception.
[Sprint HTC EVO 4G LTE] nunyabiziz:
The result below is from my Att one x. I heard the Sprint is capping bandwidth for download between 6-12mbps.
[Sprint HTC EVO 4G LTE] tmuka:
Did you have to turn on the screen before the texts came in? When I factory reset mine one of the prompts was to enable or disable automatic sync. I'm not sure if that applies to texts, but I wonder if the BBYM guy who set it up the first time chose disable...
[Sprint HTC EVO 4G LTE] neoshi:
Let's face reality folks.

The Evo 4G LTE's antennas are pretty bad. In a direct comparison between the OG Evo, Evo 3D, and the Evo 4G LTE, the EvoLTE was the loser.

With phones placed right next to each other, the results were:

-Evo 4G: -87dBm

-Evo 3D: -89dBm

-Evo LTE: -91dBm

And then it gets worse when you try to hold the phone

-Evo 4G: -89dBm

-Evo 3D: -91dBm

-Evo LTE: -97dBm!!
[Sprint HTC EVO 4G LTE] djschny:
Reality Hits You Hard Bro

Thanks for concrete numbers to confirm my not as thorough tests. No software update is going to remedy this either, it is all hardware problems from what I can tell.

Harsh reality is that by end of week I will be returning mine and having them reactivate my original EVO 4G and will most likely wait for the S3. I really wanted this phone too :(, but can't get past this issue.
[Sprint HTC EVO 4G LTE] tmuka:
I've blamed the bad 3g speeds on the Sprint backhaul since at times with full bars speeds are in the 20kB/s range, but today was surprised Verizon 3g roaming speeds (using roam control) weren't any better than Sprint at my usual 3/4 bar signal levels...

I also drove to a less population dense area by the grr airport and was pulling almost 1Mbps at full bars... I never see those speeds around hinge or work...

Any idea if the evolte's 3g and 4g use the same antennas? Of course, I'll probably be happier with 20% of max LTE speeds...
[Sprint HTC EVO 4G LTE] neoshi:
Yeah it's a bit sad to see these numbers but do keep in mind that I don't have a SGS3 (or even SGS2) on hand to compare. The numbers I gave should only be used to compare against other phones in the exact same situation. The OG Evo was my baseline here, since it performed without issues in voice and data quality in these situations. The handheld numbers are then used to compare to the untouched handset numbers to see if we have a significant reception issue when held.

I do believe if HTC can find a way to replace the battery cover and its antennas with a better set, we may see better results.

EDIT:

Found some info on the SGS3 ERP data submitted to the FCC:

Maximum RF ERP: 17.78 dBm (CDMA1X 850), 20.77 dBm (EV-DO 850), 24.05 dBm (CDMA1X 1900), 23.85 dBm (EV-DO 1900), 17.21 dBm (CDMA1X 800), 17.56 dBm (EV-DO 800), 22.01 dBm (LTE 1900)

vs

the Evo LTE:

Maximum RF ERP: 20.43 dBm (CDMA1X 850), 18.74 dBm (EV-DO 850), 22.98 dBm (CDMA1X 1900), 18.44 dBm (EV-DO 1900), 20.01 dBm (CDMA1X 800), 18.75 dBm (EV-DO 800), 19.85 dBm (LTE 1900)

As you can see, there are certain areas where the SGS3 shines and certain areas where the Evo LTE shines as well. I have used bold to highlight where each phone has its advantages.

I have noticed that if I don't put my fingers behind the phone, it will have decent signal... but then I can't hold the phone without fingers behind it! Lol
[Sprint HTC EVO 4G LTE] proxybox:
It's a hardware issue

I noticed that depending on where I put my hand on the phone, the reception changes considerably. I did a quick search yesterday and found this article:

mobilebloom.com/htc-evo-4g-lte-plagues-with-signal-strength-issues/2214916/

It seems that the phone's antenna's may be affected by the aluminum shell. Let's see what Sprint and HTC say about this major issue.
[Sprint HTC EVO 4G LTE] tech7:
Well I usually get 3 to 4 bars now it's just constantly full bars and 3g is 2.7 mbps stable all day
[Sprint HTC EVO 4G LTE] megabiteg:
I get avg signal comparing it to my EVO 3D but what annoys me the most is that 3g and WiFi disconnects like crazy. Sometimes I can be browsing and the network connection just disappears and comes back. I would even do it several times in a row... Hope they fix this fast.
[Sprint HTC EVO 4G LTE] ricoishere2:
Had 2 PRL updates in the last 3 days, improved my signal strength by ~30% I'd say. Went from horrible to tolerable haha and I seem to stay over 40% everywhere I go now. It's still not where my old evo 4g was but it's a lot better. I was worried for awhile and close to returning the phone but now it's a keeper. :)
[Sprint HTC EVO 4G LTE] MadFlava:
Im probably goingto return mine this weekend. I dont have any other phones except a really old Blackberry. I dont have enough time on my 14 days to hold out for the SGS3. Once again Sprint is screwing their customers with subpar equipment and long term contracts. Selling you defective equipment? Not our problem! You're locked into a contract now! Send us money!
[Sprint HTC EVO 4G LTE] thenags:
It's literally to the point where I don't attempt to do anything data related unless I'm on wifi. I hope this gets better soon.
[Sprint HTC EVO 4G LTE] greymalken:
Are you guys, the ones with signal issues, rooted and/or running custom roms? I'm still none stick and the only issue I have is that sometimes when "roaming" my phone refuses to send texts. It'll receive them though.
[Sprint HTC EVO 4G LTE] QWIKSTRIKE:
I can tell you that while I was in the Sprint store I was receiving a 79 dbm while the EVO 4G LTE was displaying 105 even though the bars were completely filled. I wonder if the way the EVO 4G LTE receives signal and reports it is different than other phones.

Also just remember with Network Vision on the move the issues could be network related as I am having network issues here in NY with my Photon. It seems Sprint doesn't want to credit for poor service so they deny any issues while stupidly losing customers...what a joke! All this to say that Sprint's network being upgraded could be the issue....

[Sprint HTC EVO 4G LTE] om4:
A good while back I set my EVO to CDMA only, the way I saw it leaving it in hybrid would disrupt my 3g whenever the phone starting searching for LTE, then I stopped dropping, after that I got the data usage warning bumped it up to something like 10GB, I don't really use much data but its a new phone with a beautiful screen that screams play with me, well I apparently hit my new usage limit (and surpassed by 8GB) and it didn't notify me, but my 3g did start dropping again so I lifted the limit yet again and it has yet to drop 3g, of course it could be just a coincidence, can anyone confirm?

edit: it was just a coincidence, signal is dropping like crazy

I mentioned this in another post;

I think google voice uses wifi for texts, so if sprint signal is low texts sent via voice should be fine whereas stock messaging relies on the overburdened sprint network...
[Sprint HTC EVO 4G LTE] waterbound:
Am I the only one who has great signal???

Kind of kidding because for me I don't have any issues. This screen shot was running from Speedtest and we know how accurate that can/can't be sometimes but in Annapolis, inside an elevator, I am getting these speeds. Hopefully there isn't a hardware issue, could be but there seems to be a few threads on the exact subject here so imo, no issues with my cell, rooted with Fresh version1, stock kernel etc..
[Sprint HTC EVO 4G LTE] wuestsider:
Well I re-provissioned my phone and it appears most of my issues have stoped. However, I did get some double text earlier, but I realized that it was due to my airave.

Additionaly, I've been doing some research on this issue and it appears that even though we all wanted this phone really bad, Sprint should have waited to release it after they upgraded their systems to LTE. What I've been told; most of our problems can be attributed to Sprints poor 3g service along with some minor Sense 4 bugs. However, I do see HTC sending out a patch sometime soon, but we all know Sprint isn't as efficient.

Hell, when I originally got the OG EVO the day it was released, I was told many times "Its a 4g phone" and that was great, only if Sprint established 4g service in my area, which till this day they haven't. But they were still more then happy to charge me the extra $10 amonth for the service..... Good ole Sprint ..... But right now they seem to be the only major carrier that truly offers unlimited everything plans.
