Ok just got my evo 3d and in the heart of Sprint coverage had great 3g and call signal in my location with the Evo 4g, now i don't have 3g coverage and i have seen better signal strength on Cricket Wireless. I don't know if the power was reduced to the antenna or what the problem is but fix it this is seriously messed up.
P.S. 4g coverage is 2 bars on both 4g and 3D
I've noticed the bars on my 3D are usually one less than they were with my 4G. When I run speedtest with my 3D though, the d/l and u/l speeds are comparable with tests I had run with my 4G.
When I've got the 4G antenna turned on on my 3D, I'm seeing the exact same number of bars and d/l and u/l speeds that I saw with my original evo.
I have this same issue. returning the phone for new one tomorrow with hopes this is not going to be a constant issue. If it is I may just get the Nexsus S, I had the evo before and loved the phone but the Nexus S has much better support since its a google phone. ie.....Netflix and hulu plus before others.
You can tell some people don't actually read the forums. The number of bars shown has nothing to do with what the actual reception of the phone is, it appears there may be a software issue preventing the phone from showing an accurate signal strenghth according to CAPTPACKRAT1's testing of the phones. I am showing one bar less than the evo too, but the calls are fine.
The issue for me is definitely a reception issue, I have had calls dropped and had the phone go into roaming in places where my old Evo had good coverage and never dropped calls. Started a service ticket with customer service and I am going in to the Sprint store on Saturday so the tech can run some diagnostic checks on it.
I am having the same issues as the other people in this forum. It is very frustrating not to have signal at home with new evo 3d. My HTC hero worked excellent for almost 2 years. For 5 years I did not make any single call to Sprint's call center. With this phone I had already call Sprint twice. I will try one more time visiting a service center and if I am not satisfied I will return my phone and maybe change provider. I have been a. happy Sprint customer for almost 10 years. Many people are having issues with this phone.
Update: 7/12/2011 1:33pm
This morning the signal got worse. I was not even able to send text messages, some kind of "Radio Signal error". I expected it to be cleared-out at work (11 miles from home). The error persisted, so I rebooted. As the phone was rebooting there were all these updates on PRL, firmware, etc. I decided to have lunch at home and re-test the phone again after the updates. Great surprise: I am getting between 2 and 4 bars. My data speed has increased to 600 to 2000kbs. I am very happy now. I will continue testing the phone for the next 2 weeks, if everything is working fine I will keep it otherwise I will return it.
I am happy right now.
Same issue here.
I'm not focusing on bars but on what has occured from having my Evo 4G in a area that Sprint says has the "best coverage possible".
My 4G never ever went to roaming, didnt suffer from dropped calls.
The new 3d has had multiple dropped calls, Erro 78's telling me it cannot connect to data, and constant "data roaming charges may apply".
I'm seeing a lot of people not having these issues and alot who are, which make me wonder if there was just bad batches of the devices or maybe different hardware revisions that suffer from this.
My device is hardware version 0002.
I went through all the steps with sprint support and HTC support, so far nobosy has a clue.
I'm taking the phone down to Sprint's repair center this week to see if they will test the antenna to see if it may not be as sensitive as it should be.
Great phone, just the reception over all (3g/4g/call) that is letting it down for me.
Like yourself I have been using HTC phones since Sprint started carrying the Hero. I am on my second EVO 3D in less than 30 Days! Everyone listen up: This phone
is a DUD! The Fix is coming on July 31st, Sprint is releasing the Motorolla Photon. Go to cnet.com to see specs. If anyone with a 3D EVO can exchange I seriously advise doing so.
Well the answer is in.
I had my local Sprint tech center run tests on the antenna and they confirmed that the phone failed the tests.
A replacement phone is on the way.
Sheldon, did they mention any hard data in the results/numbers? My second unit is marginally better than the first but I'm still only getting -101dBm to -85dBm at best on this phone, outside, facing the tower (1500m away) My wifes Droid Eris (verizon) gets -60db everywhere INSIDE our house. Sprint tells me that this is an excellent coverage area, and so do some consumers I've spoken with. I was advised by tech support to take it in for an RF test, but I'm told I have to go to the service center that is 40 min. away because of some sort of market restrictions. I'm reluctant to do that, I shouldn't have to drive all the way there and back just for them to tell me that either my phone is crap or my service is. Phone tech support can't solve it, according to them there are no reported issues in my area, but they won't suggest that the phone is bad.
I monitored both units on OpenSignal and watched the phone cycle from tower to tower like the hands of a clock. I've got three towers within 2500m of my location. Seems to be a quality issue with these units, but everyone's trying to turn a blind eye to it. I have 25 of my 30 days left to make my choice, but for the headaches I'm getting from this, I'm just about ready to go back to verizon. I was really excited to get my hands on this phone and looking forward to 4G service in my area, but it's turned into major disappointment and aggravation.
They meantioned no numbers at all when I asked.
They said the device failed every test they threw at it when testing the antenna.
I got my phone from Amazon at full retail price which was a bit of an issue, the good thing is that the sprint repair center offered to swop out the device even though it was not purchased direct from them.
The "down side" was that the replacement is "seed stock" which could be new or refurbished, to me I personally dont care as long as the device has no scratches and is in good working order.
I myself live literally 6 minutes away from a sprint tower and got numbers in the 70's with my EVO 4G, outside with the 3D I get the upper 80's in dBm.
Inside I'm at 101, this happily jumps up to 112 and then drops to roaming at any time during a call and even when not in use.
I'm lucky that I have a Sprint repair center just up the road from where I live, I dealt with Sprint support over chat and phone and the same with HTC.
None of them "apprently have this issue reported about the device", when I responded to the HTC techs "thats funny cause there sure are a bunch of people complaining about this who say they have reported it", I then got no responce and they proceeded to move on with troubleshooting "which simply entailed a PRL update, a Profile update and a factory reset.
Even thought your sprint repair center is pretty far out I'm thinking this is the only real way to go to get a new device.
I'll be curious to see if the new one has better signal, and if so what the hardware revisions are between the replacement and this one.
Well brand new phone in hand, so far my dBm strength is exactly the same as the old phone.........
So we will see what happens call wise, I somehow doubt they tested this ones RF signal.
