HTC EVO lte connection issues

[Fifth313ment]

I want to try what you did. Did you have to p[ay any fees? Did you have insurance? Did they use the insurance? Was it a Sprint store. We need some more info bro.

I contacted HTC yesterday about the phone not automatically connecting to the LTE network.

After telling that I was across the street from a known LTE tower and sat there for 10 mins and phone would not connect.

After doing the toggle it connected.

The rep told me that nothing is wrong with my phone and it is because of how the signal is transmitted from the tower. So its basically a sprint issue.I currently have 2 other lines now eligible for an upgrade but I dont think I going to use them for Evo Lte.

That's ridiculous. How is Apple not thwarted by these supposed Sprint issues in the new iPhone 5? Lame, HTC. Lame.

Don't they have their antenna set up differently and geared to get stronger signal and the reason no split antennae for svdo?... Or somin like that

I think this is ridiculous as well but I am not AJ and you so my technical understanding of a few things are still in its infancy. With that being said, is it technically possible that how a signal is being transmitted from a tower(in this case lte) can affect one device and not others like what the htc rep allegedly said?

The only difference is on the device side. SVDO is not an issue. The HTC works fine in 1x and EVDO mode, and handles SVDO just fine. It is only LTE that EVO has had LTE connectivity issues with.

 

Even though the HTC has multiple LTE antennas, it doesn't interact differently with the site than all the other MIMO Sprint LTE devices. Two diverse antennas on the device have two separate data sessions going on with the LTE site. If there are any flaws in that setup, it would be an HTC issue. Sprint is not doing anything unique that no other LTE MIMO carrier does.

Correct Sprint is just passing the buck.

 

I emailed quite a few mobile and tech news sites last week. Not sure how to make some noise enough to get them to come out and say something.

 

I keep thinking something is physically wrong but then the LTE only setting works good. But then you ask why haven't they fixed it? Samsung did on the same chipset.

 

Very very fishy...

Oops... I meant HTC is passing the buck. And not going back to edit since it will spew html code all over the message and cut it at the bottom.

Geez, what the hell do you expect? You were almost certainly talking to a phone drone, an entry level worker who knows next to nothing. I am ceaselessly amazed that people think that a call center worker has engineering knowledge or executive power.

Wasn't saying svdo was the issue. Was just tossing it out maybe its the design overall as we see apple bc of their antennae setup evidently get better call quality and signal...and was just saying svdo was one of the things they dropped bc of their setup...was not saying no svdo is reason for strong lte connection... BUT also not recalling if the cdma and lte is being done through same antennae either as I believe the lte one was totally separate which would toss my theory out the door completely anyway...

 

Everytime we talk signal all I remember is AJ's comments on the EVOs FCC docs showing it had lower numbers than desired really...

It is completely plausible that all the EVO LTE problems are related to low radio performance and not specific to any software or hardware malfunction. AJ and I were talking about it recently. The EVO LTE may just be a weak LTE RF Performer.

Yeah if LTE only continues to be good, then it still leaves the opportunity for HTC AND Sprint to get their ish together and code it right.

BUT the LTE Only setting working throws a wrinkle into that theory...lol

 

It's one of two things and right now we have theories for both. Hehe...

Yes. I even made that point. But I have quickly forgotten.

I guess the LTE only works better for some and not so for other. The LTE only setting at times can be as flakey as the normal settings. On my phone I have failed to gain connection in the same area other phones have reported connections. The issues appears to rest in software or radio performance. I have also had the phone crash randomly in LTE only.

But does the phone work fine in LTE only mode regarding initial signal acquisition or just in maintaining a weak signal?

[cbalter]

My EVO has a hard time acquiring LTE and keeping it as well.

I did have to pay a $35 fee since I dont have insurance. The store I went to was not a sprint cooperate store... it was a "sprint preferred retailer

 

Hope this helps.

My experience is it connects and holds the signal fine at times in LTE only mode. But the phone does the same without changing the network values at times too. There are times when the connection will get to -123 before it drops over to 3g, this is with cdma/evdo/lte setting. The only reason it appears that LTE only mode works better is the phone isn't looking for any other signals. Which would make it appear that the 3g threshold is higher than it needs to be. The argument could be made that the LTE threshold is to low.

I personally have stopped using this setting since I can't use my phone for anything but internet.

Use the LTE cdma only setting which is LTE AND 1X only.

Didn't happen on the Epic and doesn't happen on the S3.

 

I do notice that a lot of times the Evo will say ehrpd and the S3 will say only evdo. Not sure if the airave is causing that and it just takes a while to switch over.

Hey guys, long time listener, first time caller. I started visiting the board several months ago trying to get info on the timeline for the lte network roll out in my area, and to get some details on the apparent lte connectivity issues with the HTC Evo lte. Because I really love the build quality of the evo and hate the way the GS3 feels in the hand, I've been trying to wait on a solution to come out that resolves the Evo's issues. I really respect the knowledge and insight that is rooted in his community and I registered to ask a question. Do you guys think that a solution is possible? More importantly, do you think that Sprint and HTC are still working on a solution. I don't want to take the chance, spending that kind of money and have the phone not be able to utilize one of its biggest features, lte, with the network upgrades on the horizon in my area. Because I read all types of sites looking to see if if there is news of a remedy, I came across this:

 

http://forums.androidcentral.com/htc-evo-4g-lte/218202-4g-lte-connection-fix-sprint-phones-worked-me-least.html

 

The guy seems like he really knows what he's talking about. But, I'm not an expert, you guys are. Does this work? I hope it does, I would really like to buy this phone.

 

Thanks!

People have toyed with the scan number but it doesn't seem to make a difference. The problem is more than changing just one number, otherwise Sprint would have did that many months ago. Don't zero out your RTSP numbers either, placebo there and messes up you updating the profile/prl if you need to.

[wjrandon]

Killing the RTSP server will cause streaming applications not to work on your device. Sprint wont funnel data from high bandwidth consumption sites i.e. Youtube, Pandora unless the data is compressed and funneled though their proxy server.
