WiFi Attenuation? - Sprint HTC EVO 4G LTE

Hey Everyone,
I'm pretty new at posting on XDA, but I have been going here for ROMs, Kernels, and advice since I got my OG Evo all that time ago.
Regardless, I've searched the forum and Google for anyone experiencing this problem, and I haven't found any anecdotes or threads on it. Ever since I've got my new Evo, I've been able to attenuate the WiFi signal just by grasping the top half of the phone or by handling it like I normally would in landscape mode. I could see the WiFi symbol drop down by two or three bars a few seconds after placing my hand on the top cover.
Obviously, some signal attenuation is predictable since the cover contains all the antennas, but I did not think it would be effected as much as it is. It seems to cut down the signal by at least half in terms of data download speed. Have people been experiencing this much of an effect?

Starting from the earliest run, I did six runs alternating between holding the device at the bottom and holding it either in landscape or grasping it by the top half.
My 3G signal isn't bothered by my hand at all, probably because of the wavelength difference. I'm just curious how much other people's signals are affected. Obviously, the speeds are still decent enough that it doesn't bug me too often. I will notice that sometimes I have to restart certain downloads/refresh loading pages due to inconsistency in the signal. And I'm sure LTE won't be affected since it also has a relatively large wavelength compared to WiFi.

Known problem with the ONE series but not the EVO LTE, take it back for replacement as nobody has this issue.

Failed .15 update from .14 equals better battery life?

Like the subject said. I've got an unrooted (my lazy ass haven't gotten around to it yet....) TFP running .14, went to go update yesterday morning only for it to fail after looking at the poor guy lay on his back with his panel open for half an hour. Not a big deal in and of itself, but my battery life has increased drastically since, with no change of use or settings. Same start up programs, same power settings, nothing uninstalled/reinstalled, nada.
Not that I'm complaining here, but any thoughts? I'm kinda scratching my head here...

I'd hardly call an average of an additional 2 hrs of life a placebo effect. With WiFi on for duration, moderate internet use for video conf, and heavy note taking I would avg ~7 hrs from 100%-dead. Since yesterday morning, ~9 hrs between charges.
placebo effect my ass.

The absolute most it did was 'bump' charge your prime, nothing more. You'd probably get the same result from fully charging, powering off, then let it charge for a while again.
I considered that, but that's exactly how I charged it for the first week I had it last month (since I'm old school and still condition my batteries). Literally nothing has changed in the last month as far as use goes. I dunno, maybe it's just a damned fluke.

[Q] Has anyone noticed improved 3G speeds? Post speed test results

sooooo I have gotten use to the awful 3G speeds that I get most of the time around my area. Some days you have good days but overall they have been in the gutter. I don't know if today is just a good day or if the evdo radio is actually that much better in this phone.

I never got even close to that speed on my 3D, I have ran multiple test to see if it was a fluke but they have all come in great ping times, 1,000kbps+ with about 675 up average. Pretty impressed actually, my 3D in the same area would bounce all over the place 500 average maybe sometimes lower. Anyone else seeing this in there area?
Also 3G actually works great while on the phone! I have been waiting for this feature for YEARS, I read rumors about it but didn't think it would actually work. Wayyyyy better - I heard towers needed to be upgraded for this to work - is it working for you guys as well?
I traded in my ET4G but after testing a zillion times here at home I never got above 850 and that was only upon rare occasions. Most of the time I was between about 350 and 520. I am now pulling 1200 consistently
My 3g sucks as always!!!

WAY faster than my hero! My hero would usually pull like 50kbps
I'm still getting the same results

Wifi (and or 4g) equal bad signal??

well, pictures say it all, please chime in if you have some info or an explanation

with 3g
I've seen this before too. Not entirely sure why but guessing it put the radios to sleep sort of to conserve battery on wifi. Like, perhaps it keeps enough signal to send and receive but doesn't need to power it enough for fast data. Just a guess though because I've still been able to send and receive texts and phone calls fine with the signal like that.

the wifi would be my guess. as for the no 3g but full signal is probably because you're standing right next to one of sprints towers.
My wifi is just as bad and my PS3 and computer are just fine... If you find out please share.

Getting LTE in Wichita metropolitan area

Just thought I'd share. LTE was crappy this morning but for better closer to midnight

Swyped on my EVO LTE
That seems pretty low. Hopefully its just due to it not being fully rolled out yet
Holy ish.... I didn't think I would ever see this in my home town..
Sent from my EVO using xda premium
I first picked it up in Valley Center and by Hartman Arena in Park City. But yes it does seem a little slow and at times it would drop the network and reconnect almost immediately. I hope it does get faster. But right now i feel like moving to KC for the LTE and Google Fiber.. /nerdgasm
I just ran some speed test.. It's not doing to bad but I've never had anything better than 3G so I might just be in awe...
I also wasn't getting internet at first so I updated PRL and profile and now it's screaming fast. (compared to 3G)

There are only a few towers with LTE in wichita right now. Once the roll out is complete it will be better.
They're definitely working on it. Im getting a signal at my house I wasn't getting a few days ago. I forced lte on my evo and have been connected and surfing for about 30 min now without dropping the connection. Not super fast but can't wait to try it when its complete. I wonder how long it'll take. Any guesses?
Well sheeeeeeyit. I was just in Wichita a couple days ago to visit the folks. Didn't even think about trying LTE tho...

Just got my new USB board in, now i cant get LTE. Have a question about a antenna

Ordered a new USB port from china. Just came in today and so I sat down to change it out. Noticed on the new one that its for a N7000 but my order says for a i717, decided to try it any way as I need to phone for work and it not charging properly is a big issue.
When I got my phone apart I inspected both parts to see if I could see any major differences, only one I noticed was on the i717 board it has 3 contact points on the bottom right, compared to the new one that only has 2. Figure I'd see if it works anyway. So j got the phone back together and everything seems normal but I can't pick up lte. My signal strength hasn't changed but I just can't get LTE. I changed my APN but its still a no go. Is the Cell antenna part of the uSB board? Couldn't really find any diagrams in google. Thanks

You can see the 3 contacts on the picture, that's the original part, the new one only has 2, the one on the right is the one I'm missing
I just changed mine about a week ago with no signal issues ...... Google both our device and the n7000 charging ports and see if you see a diff

Looks like the third contact either is part of the mic or the lte antenna, realized after a call that the mic wasn't working, so I reinstalled the old one and lte instantly came back and my mic was working, orded another so hopefully they sent the proper part this time
The antennas are up by the power button. But its generally bad to have an incomplete circuit somewhere (3rd contact).
