Hello everyone, I started using this Evo yesterday, and already have had 4 dropped calls. I have already swapped back to my old phone, and I'm wondering if anyone knows of a solution to fix this dropped calls issue. At this point this phone is on usable for my business, and I am about to return it.
where are you from? because sprint is in the process of updating every single one of their towers (not all at once, but going from city to city) to enhance the 3g performance on newer phones such as the evo lte. During these upgrades however, the call quality and internet speeds are terrible. i know because my towers are being updated now and the sprint everything is terrible here at the moment on my lte. however my dad with the old evo has no problems what so ever.
My other phone has no problems, nor does my wife's Sprint phone. So the problem seems to be this particular phone.
It is a known fact that the EVO LTE has less coverage due to the RF capabilities.

If that is the case then I am definitely going to dump it. Looks like a GS3 for me. It's too bad they can't make this thing at least as good as the first 2 Evos. My wife's 3D has performed flawlessly for a year now.
Depends on how you look at it. I was in a fringe area. My phone switched over to roaming and was usable there. The G3 was not usable as it kept trying to hang on to that poor signal.
From what I have seen too, the EVO is better in the 850 band so roaming you would have even more coverage plus when 800smr fires up for your area you will get better coverage there as well. Pros and cons...

Thanks for the info, however I was in my apartment for all of the dropped calls, and I do not consider this to be a fringe area... the other phones that we use here work fine.

Dial ##debug# and go to the 1x engineering. Post the rx pwr and rx ec/io number. Curious to see what's up.
Sent from my C64 w/Epyx FastLoad cartridge
Thanks digiblur.
rx power -84dB (but it changes constantly between -80 and -88 or so)
rx ec/io -9.0db (again, it changes constantly between -8 and -11.5)
my Photon sitting right next to the Evo has a rx ec/io reading of 110 dB (?!?) and rx Power -84dB and never drops calls.
I don't know what I am talking about, but could this be a PRL issue?
Photon PRL: 51090
Evo LTE: 25005
I am also wondering of changing from LTE/CDMA to CDMA only in the network settings will help battery life when there is no LTE in this area yet...

There shouldn't really be a noticeable change in battery life with cdma/LTE unlike WiMAX 4g which has drastic effects on battery...if there are tower upgrades underway in your area after they're completed you should be sitting on top of the world lol

No, a PRL isn't going to effect your native Sprint signal. Something is odd with that Photo EC/IO. An EC/IO is always a negative number, without going in to huge detail it deals with Pilot Channel pollution...kinda like the interference level or health of the pilot channel. If it is worse than -10 than your handset may search for a sector with a better EC/IO. But I've seen -14 on mine in places and no issues. -84 dbm receive signal is good...nothing really wrong with those numbers, especially indoors. It's not a linear scale, but basically a -60 or better means you are very very close to the tower and -103ish or worse is about to fall off the cliff.
So this information says nothing about the dropped calls then, right?
I always drop calls but usually its bc my phone randomly goes into airplane mode by itself while on a call..es . drives me nuts
Firmbiz, did you root or mess with your phone at all?
Try changing system settings to EVDO Only.
The default stock setting is EVDO/LTE.. I have yet to have a dropped call but im also not a heavy talker.
I do use data and noticed this helped with some data issues.
Make the switch and then power off the device, and power it back on. Make sure you have fast boot disabled as well.

Seems like an issue with your local tower or maybe a bad phone.
Sent from my C64 w/Epyx FastLoad cartridge
I will try it with LTE off and see if that helps with the drops.
Also, re: "Seems like an issue with your local tower " all of our other Sprint phones work here without issue, so it seems that the tower is fine.

That doesn't mean anything. I have seen some phones have issues in areas and others didn't. Call Sprint, they may rebuild your line and recomission your phone.

I just got my phone yesterday and noticed it today at work. With my og EVO I would consistantly get 3 bars at work and with the EVO 4g LTE I am getting 0-1 bar and roaming a lot which is killing my battery as well. Is the antenna is this EVO not as strong as the og EVO? This is a pretty big problem because I use my phone all the time at work. Iv tried updating my profile and prl and have done a couple resets. I don't want to return this phone but I may have to

No idea how it compares to og Evo, I have since had 2 other phones plus this one.
But I wouldn't call the reception weak.
You can try and do what I do - force roaming with an app like Roam Control. This way you may have a better signal and good battery life.
For me, the signal strength is pretty much exactly like my Original Evo. The wireless actually working on the other hand is not.
My signal is aweful compared to my og EVO. Right now my signal is -105dbm
Strange. My signal is 2-3 bars better than my OG...
I'm having issues with 3g staying connected. I'll lose it turn the radios off and turn back on. It days connecting that's it. I have to reboot to get data working. Updated profile and prl but wats odd is that it always updates and never tells me that I have the recent prl. Any ideas? It's really pissing me off!
I thought it was the weather but yea. My og seems to pick up signal in remote places better.

Yes it is a known fact that the antennas in the new EVO are less efficient than the original EVO. Someone compared the FCC docs but I don't remember the difference. I think it was 2db difference.

Thanks for the info. Looks like ill be returning my EVO today sprints coverage where I work isnt the greatest to begin with and with a weaker antenna makes the phone almost unusable. Come on HTC and sprint, if your going to charge 200 for this phone at least put a decent antenna in it so I can do the basics like calling and emails.
I'll be sitting in one spot and my 3g will drop and the. Come back . It's kind of annoying
Mine was having problems roaming to other towers as well but I went in and changed the preferred network mode from LTE/CDMA to CDMA only and it's much better.
Took me forever to find where it was located: Settings -> Mobile network -> Network mode
Thought that hitting mobile network would just toggle it on/off but if you don't hit the on/off button it puts you into a submenu with more options.
The Wifi antenna seems much better but the mobile antenna seems not quite as good to me. Once I changed it CDMA only it's comparable to my OG Evo.
i'm having the same issues, I loose 3G connections, I have very low signal strength and it is killing my battery..
Ya ive seen a few people with this same issue. it seems like its only in places where i have a weak sprint signal is when the Evo 4g is worse than the OG.
Right now I am sitting at home and the OG evo is -84 dBm and the Evo 4g LTE is -79 dBm so the 4g LTE is actually getting a better signal than the OG.
Im going back to work later and im going to see what the numbers look like there. But on the 4g LTE i was barely able to get a 3g signal at work but the OG evo always had one.
internet/phone sig are different; color of switch
I wonder where you are located OP. We called Sprint and they keep telling us that they are "repairing a tower" near us in Mass.
Two additional notes. First, our internet/3G seems to be much faster since the upgrade from OG to this device. Ookla confirmed this too, about 3-4x faster download speed, 2x faster upload (about 800+ each). However, we have two devices and neither of them can phone anymore! Sprint even drops our text sms sometimes. We are thinking of returning the devices since Sprint has told us three times (one week ago, 3 days ago, and today) that they are "repairing a tower" and always changing the date (now to June 8).
The other thing is that one of the devices, in settings> shows whatever wireless/network is toggled on with red switch, and the other device shows the toggled on with green switch.
Does anyone else have better internet and no phone?
Does anyone else have red switch? It seems logical the "on" switch should be green.
Note: It doesn't make sense to me that I still get 3-4 bars on my old Evo (which was obviously deactivated) and it calls out to a "sorry no service" message loud and clear, but my new Evo can't even reliably send a text much less make a phone call.
Same problem here but mine is weird. I will have full bars and out of nowhere, I drop to 1-2 and it goes into roaming, except even though it's "roaming" I have no data or voice (yes I enabled roaming voice and data). It will stay like that from 1-8 seconds and then go back to Sprint's service. Also, if I tried to send a text during that time, it will fail and if I was getting a call it wouldn't show for 30 to an hour later.
What's weird is that my girlfriends Evo LTE was sitting right next to mine and had full bars all the time with no problem. I am thinking at least mine is a hardware problem. I'll monitor mine for another day and then take it in if the problem stays.
Mine helped switching to cdma only.

I've been doing that for a couple days and just yesterday it started dropping 3g for no reason again... Cell is just fine everywhere, but i called sprint and they said that there were tower outages until June1st. I'm sorry but i could've sworn today is the 4th? And i guess there is no more tech support department? Because I've called twice and they won't transfer me. Grrr
Sent from my Viper tuned ltEVO
So i was able to do some testing and found the Evo 4g LTE to be about 10 dBm less than the OG Evo in almost every place i tested them. Also sitting in my house about a quarter mile from a tower my 3g speed on speedtest.net was 97kbps down and 51kbps up with a 255 ping!!!!!
These speeds are not acceptable even in 1x let alone 3g.
I am trying everything not to return this phone but these kind of issues are so disappointing. I never had issues like this with my evo when it first came out :/

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!

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.
I have been having an issue with my EVO LTE. The other phone in my house, EVO Shift, does not have this issue.
I have an Airave. I have been talking to Sprint with no success. They have sent me two new units out of "Lets try this"
The issue is as follows:
My phone occasionally links to the Airave, but generally only for a moment. Every now and then, it will stay. But for the most part no. My phone, and only my phone, seems to ignore the unit. Even when I have no signal. I have updated PRL numerous times and tried all network modes with no change. What is very strange, however, is the data side will connect. I installed a few signal meters and noticed that voice signal is almost zero but data is full like it should be. Speed tests confirm I am running data through the Airave. Why would the Data side connect, but the Voice side not?

Ok, well that kills that idea. I know this doesn't help but I don't have any issues using the Airave on the EVO LTE, so it's something specific to your account and/or setup.
When you go to the ##DEBUG# screen, 1X engineering, when in the same area as your home but not near the Airave coverage what does your SID, Channel, and NID show?
Does any of this change when you go to the Airave coverage area?
Mine does the same thing. Spent hours on phone with sprint. Still does it. I gave up.

No problems using my Evo with my airave.
Just curious, does anyone else's evo not connect to 4g unless they cycle 3g on and off? there is one area a few miles from my house and when i go up there (knowing there is solid 4g) my phone will stay on 3g the whole time im up there. now if im up there and cycle airplane mode or flip my internet on and off then it connects to 4g right away as soon as the radio turns on, no problem. Occasionally if i leave my phone in my pocket it will hop back to 3g but then it will stay there again until i flip off and on my internet and then like magic my 4g is back.
Does this happen to everyone else or is it just me? haha may just be the tower also considering im a little southwest of chicago and they haven't really officially launched per say.
It's a common problem with the EVO and HTC has not fixed it yet.
They better get to work as people are thinking the LTE network sucks. Compare it to a S3 side by side and it has no issues.
I still have my insurance and will keep it as when lte is available in my area I will be bringing my phone into the store over and over until they swap me out.
Love the EVO but if it sucks for using LTE then it has to go bye bye.

im quickly getting to that point. my wifes s3 and daughters iphone5 can hold an lte signal great. but this evo with the current radios just plain sucks.
sitting right next to each other my evo is rocking 1x, the s3 is bouncing between 3g and lte and the iphone is holding lte.
My phone finds LTE in MA but has problems with voice and won't text at all sometimes. Not sure whether that a problem with the network or phone.
Sent from my EVO using xda app-developers app
this is happening to me to i knew there was a tower right by me but no LTE connected so i changed the network settings to CDMA/LTE and held LTE until i left the area. I was getting only 1.5mbps which i think sucks for LTE. Its hard to stay what the issue it whether its the phone or actual software settings that maybe OTA can fix. Weird thing i noticed when i updated to the latest firmware is LTE only setting holds LTE and 1X, CDMA/LTE never picks up 3g so i just end up putting it back to stock settings. Really considering taking it back to compare to the store phones.
Having the same problem as well. It will connect to 4G on its own but it would take its sweet time. So the fastest way for me is toggle airplane mode. Hope it gets fixed soon.

Many people think it is just the new network but in fact it is not. You quickly realize it when you have another LTE phone next to the EVO LTE that the EVO has a huge issue. We just all need to band together and stay on top of Sprint and HTC constantly bugging them until this issue is fixed. We done things like this before, but we all need to do it again to get this fixed ASAP!

im starting to think this too that it might be the phone. OG Evo4g was never this slow on 3g and i had wimax in my house. Now i barely get 3g in my house and no LTE unless i drive down the road. It sucks not being able to pin point this. I tested it with another evo4g lte and they had similiar results as me...need to try another LTE non-evo4g phone next...
I made a thread about this last week-
http://forum.xda-developers.com/showthread.php?t=1898433
I pretty much stuck myself between two towers which I knew were transmitting 4G but refused to cycle through airplane mode or LTE/CDMA and CDMA-only modes. I passed by both and the phone never switched over.
On the plus side, my phone did acquire a fairly weak 4G signal today on its own, so there may be some hope for this thing yet.

I’m confused, is there an LTE-only setting in the latest firmware, or are you talking about the option in the *#*#INFO#*#* (*#*#4636#*#*) menu? I’m honestly a little wary of using that since I’ve heard it can cause problems that only a factory reset can solve.
yeah the options ##DATA# or when using the elixir app under telephony.
Anyone having this issue needs to call Sprint and HTC and require them to open a ticket for the issue. This is the only way it will get fixed. I hear some are getting told that it is due to the new tower equipment. So you might need another LTE device to compare it to. Others are getting told there is an update coming soon. Others are getting told that the EVO has no issues.
It is obvious though, sprint has stopped pushing this phone. They don't even list it in their lte press releases.

From what I found googling it might mean Better Service Reselection. Just need to figure out what the values mean.
So I might possibly have a fix for the continual dropping of the LTE connection, this is what I did
Enter the menu through the dialer via ##3282#
Select Edit Menu, enter your MSL number (You can get it from MSL Reader in the play store - requires root)
Select LTE Record
Change LTE scan Timer from 30 to 5
Select Menu and select commit changes, reboot and check LTE connection
I don't know if this is actually a good fix or just a coincidence that mine started working right after I made the change, I did this in an attempt to make my phone scan for LTE more frequently in hopes that it would stay connected, right after I made the change i have had absolutely no problem staying connected to the LTE network.
I would appreciate it if other people can change this and reply with their results so we can see if it actually makes a difference or not
Keep in mind that this will impact your battery life. You are forcing your phone to constantly search for a signal when you are in an area where there is none. Prl updates are now being used to update LTE info on the phone so try updating your prl

Updated prl many times only to be connected to LTE for a very short time and then kicked back to 3G, and i have not had any noticeable impact on battery life. As of right now I am at 4 hours on battery, 95% remaining, and 57% of that battery usage is from the screen
When you get to an area without LTE, the phone will constantly search for signal, that's when battery life will be impacted. This radio design is pretty low power though.
I might have to try this but I definitely do not want my battery life to go down.
Thanks
well in my case and I imagine with most other people who are having LTE connection issues, I live and travel within the coverage area and when I do travel outside the area I have a car charger with me or something of that nature, and on the other hand my battery life with the EVO LTE is so excellent with MeanROM I never have really had to worry about it

No, LTE does drain power but its set to only scan after a set time, this workaround lowers the time between scans significantly and will use more power. Some LTE phones have a separate chipset solely for LTE. They waste much more power then the integrated setup our phones use. Thunderbolt is a good example of that. Separate radios and terrible battery life

Not really. Although the correct records have to be in the Prl for LTE to work they are not pushing updates to make lte work in new markets. Also the prl is not going to fix this connection issue.

Will changing the LTE scan timer actually fix the threshold issue though?
I've found by doing *#*#4636#*#* and change the setting from CDMA +LTE/EVDO Auto to LTE,CDMA you can hold the LTE connection much longer. All the way up to -130 dBm RSRP. Even an LTE connection at -120 dBm should yield better results than 3G.
You'll still need to change it back once you are out of LTE though as you'll be left on 1X.

I wonder if this is related to the wifi disconnecting in order to save battery life. Does it only drop LTE when the screen is off or does it also disconnect when it's being used?
If it's disconnecting on purpose shortening the reconnect time shouldn't harm battery life too much as long as you're in an area with LTE.
It won't if you are in a reliable area, in a fringe area you may connect. When the connection weakens, it will default to 3g and the phone will search again. If you make this change and live in an area without, it will continue to scan until signal is found
Ok, so I was skeptical about the LTE issues of this phone. Because of this I grabbed my wife's LG Viper to see if she had 4G. She didn't, then I remembered I switched her phone to 3G only when she first got it to save battery life since her battery life sucks. When I switched back on get 4G, her viper connected to 4G right away. After playing around with her viper for a while and pulling in some good speed tests, I went back to my Evo, which was still sporting only 3G.
After cycling to airplane mode and back, my Evo showed 4G just long enough for me to get a signal reading of -113db. After playing around with my Evo for a while, I was able to hold a signal long enough to get a couple of speed tests in before it would switch back to 3G.
After playing with both phones for a while, I was able to observe that even though we are on the edge of a 4G tower, the viper did not switch over to 3G. It stayed on 4G even though the signals for 4G were pretty equal for the two phones. One thing I did find in the viper's ##data# menu is an option of "LTE, EVDO, 1X". Basically it looks like an order option for which the phone to look for service. I did not see this option on my Evo.
From what I've experienced, it seems that the Evo switches back to 3G a little too soon. Is there a way for us to make it hold on to the signal a little longer or with less db?
I will be playing around some more with the two phones. Right now, I switched my scan timer to 5. The only way my Evo is holding onto 4G right now is because I switched the data option to LTE only. The funny thing is that its been working great and holding onto 4G perfectly. I've seen it dip down to -118db and still function fine.
Sorry for the long post. I will have to agree that the Evo seeks to have a software issue.

Na this issue is more of a threshold issue I believe they are talking about. Ie seeing an EVO and an sgs3 side by side with only the sgs3 connecting to LTE... I can understand on weak signal areas as the sgs3 is supposed to have a tad better antennae and other things related to that area and such given the FCC docs results discussed at s4gru by AJ...
But in a fairly good area signal wise on both phones they both should get LTE which isn't the case at times it seems.... Hence the thought HTC needs to tweak the threshold here for us...I remember on WiMAX it was an easy edit, but haven't even looked once on our phone since I don't get lte here anyway. Lol

It is most likely a threshold issue. Too bad I can't seem to find anything either to fix it either, not in a reliable area to really justify mucking about with my phone. WiMAX was so much easier, then again just as easy to screw up. Could be one of the reasons this phone is locked down so tight
hey, im hoping to get some help.
I type in ##3282# and nothing happens on my dialer, am i suppose to hit something?
I am on aokp build 3, does that even matter?
I have had 4g in allston for a few weeks now, and for some reason i can not get a hold on that signal anymore. My phone says i have lte 13 connection, but i can not get a 4g internet signal.
Hoping getting into the phone debug menu or lte menu i can manual lock in on the tower better, but i can not get to the menu to edit those settings.
Ive updated to the 2.13.651.1 ota and PRI 2.45_003.

It does not, it just allows for the phone to reconnect faster.

Nothing has really changed and the phone updates itself.

yeah, me too. In SLC, we've always had really good GSM and HSPA service from at&t, never matching the horror stories from the likes of chicago, sanfran, and NYC. However, they decided to pull a market-driven cluster-**** and only delivery a bare-minimum of market penetration so instead of a regular 4-5bars, I see usuall just 2. But that's not all. My phone has a supreme hard-on for the LTE and will choose the LTE tower 5 miles away over the one right next to me which results in some hysterisis and rapid HSPA/LTE changes. This may or may not be responsible for periodic loss of my data connection which I don't find about until hours after i missed that important email or text (google voice). awesome.
I put up with this for a couple weeks 'cause i'm used to the S&M relationship US mobile customers have with their wireless providers (post-paid, anyway) and finally called to ***** a little. turns out that while at&t would rather we all suffer at the hands of their inept decision making by removing any kind of switch from our devices, they will make manual adjustment for those who cry loud enough. If you really want LTE gone, you can ask for an 'inset lock to 2g/3g' which will prevent your device from seeking out LTE towers to connect to. I made mention of APN's and at least one rep indicated that this made that change, but I couldn't be sure this is an actual edit to the APN on your device.
LTE is nice for the 2% of the time I can actually use it, but the other 98% it sucks donkey ballz... at least the way at&t has done it in SLC.
hope this helps someone.
The roll out in Arkansas of all places has been awesome. I get 4 bars like, sometimes 5 everywhere within 15 miles of my house. I average - 85 dbm 52 asu signal. It's awesome. I'm sorry your lte in Utah blows.

I love ATT in CT. LTE just became official in my city but its been working great for almost a year before it launched officially.

undoubtedly there are some people close enough to LTE towers that they aren't having quite the abysmal experience I am, and other people's positive experiences in other cities could indicate that at&t will eventually get it right here. I can only hope.
LTE here in Hawaii is awesome. Then again Hawaii is so small that a few towers can probably cover most parts of the island. Hopefully att can cover your area better.

i've been very impressed with AT&T's LTE network. it's a lot better than sprint's 4G/WiMAX network.

LTE is working fine here in Central NJ. The issue with your battery isn't AT&T's rollout of LTE, it's LTE itself. The simple fact is, it's not as power efficient as HSPA (yet) and phone manufacturers haven't upped the battery specs to compensate.
Now, what AT&T IS at fault for is not giving their LTE customers an LTE/HSPA toggle.

Yep. I was quite surprised with LTE coverage. It's virtually everywhere in central Arkansas, even between cities in areas that you wouldn't expect LTE.

I wish that were the case in SLC. the problem is that LTE is not available everywhere in the coverage area, and when it is, it is frequently at much lower signal strength so it's quite apparent that at&t did not roll out LTE to all of their HSPA towers in the area. With phones preferring LTE, they are connecting to towers that are frequently farther away than the closest HSPA tower and thus requiring more power. For example, both my home and work give me 4-5bars of HSPA, but only 2bars of LTE. Some parts of the city give no LTE at all. Its currently an incomplete roll out.
