Why is the Antenna on the bottom of the phone? I'll be holding my phone in an area with no bars and when I turn the phone upside down I will pick up 2 bars. I turn it back to normal and both bars go away. This is very annoying. Granted when I make a call the bottom of the phone is pointing up, BUT what about trying to download emails, or just holding your phone and trying to browse the internet.. I've seriously turned my phone upside down to do this.
As much as I love this phone, the Antenna on the bottom and the location of the micro USB slot might be enough to push me to the iphone 5 if it has a slide out keyboard.
What do you all think? Is it just me?
The antennas are at the top corners of the phone. If you take off the battery cover, you will see some gold prongs, those slip into the groves that are on the phone itself, Those are the antennas...

Those are the secondary antennas actually. The main battery is in almost every phone at the bottom, hence the external antenna plug on the TB is right under the kick stand.

I think it's probably due to RF emissions being a little less close to your brain; the evidence seems to go back and forth over the years re: cellphone antennas and brain tumors, so who knows?

Seems like the EVO is better in a few ways... The battery cover goes over the whole phone hence a flush cover for the extended battery...

Yup if you take it off the port is right under.
Does anyone know if you could connect an external antenna to get a little more consistent signal on the 4g. I get a signal but not that great at my house. If so what would i need?

HTC phones for the last 3 years have all had the cellular antennas on the bottom of the phone. Most Nokia phones too. Just about every manufacturer has been doing this, minimize radiation to the brain.
The downside is your hand blocks signal so you have to learn to keep the bottom exposed to avoid signal attenuation.

Keep your AT&T and iPhone problems to yourself
only problem is that cellphones don't release ionizing radiation so there is no danger for tumors. even if it did it would be about the same amount of radiation as eating a bananna once a day.
Ok so the antenna is at the bottom of the Thunderbolt... Mines not having any issues is yours?
Simple fix, install adw and enable
Full rotation

no I love my sgs2 and so does every that holds it, ive a major issue that i thought was caused by switching from orange uk to o2 uk, but as it happens i have full signal when the phone is rested down... however when i pick it up it drops signal... more often than not the signal completely drops out as does the call and sometimes it just goes down to 1 bar... does anyone else have this problem? ive tried my o2 sim and my orange sim its the same for both... is it possible i have a defective handset ? weak radio ???
heres my quick vid to show you what i mean, apologies for the video quality... filmed on my bb9700

well the GSM and 3G antenna looks to be located in the bottom, back part of the device. so this seems like the exact place your hand would be covering when holding the phone, so i can easily see some significant signal attentuation happening with this phone.
i dont know where the antenna was located on the original galaxy s. but all phones i own always have attentuation. not much you can do about it i'd guess.
Applies to all wireless devices - signal transmits worse through your hand than through empty air. Rules of the universe.
However, I can't seem to replicate what you're seeing. In order for bars to drop, I have to block the entire bottom of my device using both hands. Holding it in one hand doesn't seem to be causing a drop for me.
But again : air > hand for signal transmission.

That's right, quick start guide shows the location of the antenna. If you look at the back of the device, the antenna is in the lower left hand corner, opposite the speaker.
When holding the device in your right hand, it should rest in your palm.
Actually holding the device in my right hand doesn't seem to be affecting my signal though, for some reason. I might just be in an area with good signal though (3 bars of h+, stays at 3 bars when holding it in 1 hand, drops to 1 bar when covering the device completely with 2 hands, and then changes to edge with full bars).
I just tested with my S2 and I had no problems whatsoever.
See my youtube channel (../user/Poppefieke) Can't post links yet.
I have some other S2 video's there too
i think sampullen who has been posting quite a few vids on youtube is going to cover this now too, see i hold my sgs2 in my left had for holding when im surfing etc but also when im on calls...
its good to hear some of you cannot replicate this, maybe mines faulty might try to exchange for a new 1 just to be on the safe side
OMG!
can more people confirm if this is real?
is it as bad as the antenna-gate issue from apple or no where as bad
Hey (samjpullen) here
I have been doing the tests like Sticky and have been getting some rather conflicting results to say the least.
I am not in the best area for Orange so i get a weak signal most of the time, when i do the test infront of my iMac and extra screen with the TV, Sky (you know the drill) on it seems to drop down from H with 1 bar, then down to 3G then down to G and then it can jump onto the Edge network (rathe strange)
But when i do this same test in other rooms e.g bathroom, other bedroom, even downstairs with the tv etc on it is fine!
So my guess is that it might be my rooms location and maybe all the electrical equipment within a small space.

cheers sam,
btw ppl follow sam on twitter, guys good!!!
[Fix] I accidentally messed up my signal by pushing the little button on the lower right side of the battery. don't do this I could only achieve EDGE after, if that. so what I did is use a 4 inch copper wire and electrical tape. place one end of the copper wire in the little hole(it's a part of the antenna receiver group) and use a thin piece of electrical tape to tape it up the back side by the battery. now I have a better signal then before. I recommend not doing this if your signal is still working. Do not me if you mess it up, this should only be a fix if you need it.

Dudeeeeeeeeeee! I got this very late. Last week my phone went off without notice at all, so, trying to make it come back I pressed this litle thing thinking it was a kind of hardware reset switch... Anyways, my cell came to live after 3 days, at least accepting my ON command and showing low battery (this is another issue) but now the signal reception is real poor (only 2 bars -105 dBm 4 asu) and yes...now I know that I have screwed it... Let me try your approach with the cooper wire.
Thanks
Guys be VERY CAREFULL as that to me looks like a port for an external aerial. if you short the iner pin with the outer sheild you could do some real damage to your phones transmiters/recevers
Also another thing to take into consideration is that aerial are a certain length to what freqs they work at
ie the FM areial in your car is shorter than the AM aerial, and the digital one is shorter again.
There is so much theory behind aerials that it is not funny! (im a comms tech by trade)
Just PLEASE be carefull guys!

Guys I am having the same problem of low signal at various locations. Pls do let me know if it is advisable for putting a jumper of copper wire as described.
Do I need to solder it with the hole ?
Will I loose my network permanently ?
Up to you
I would advise trying a different carrier or ask someone with the same phone/carrier how their signal is. I would only use these methods for emergencies like my situation, or like the other where he had next to no signal where he lived. As for soldering, i never thought of it, i revised my method, which i should post screen shots, by placing a larger wire in the hole and using a glue gun to hold it in place. I take no responsibility for antenna loss, because once you shove something in there, you won't have a signal unless something is in there. Good luck, i hope you figure out what's best for you and don't forget to post your results =D

Thx.. but same situation as yours the signal keeps fluctuationg n sometimes no signal so its kind no-no use sometimes or bad signal.
So I was thinking of putting a copper wire as suggested and checking it out.
As you mentioned like in near future if the wire breaks or think of removing it, I wont be able to get any signal in furture ..
Do you suggest replacing the antena & what would be its cost ?

Send it in, if it's under warranty . If it's just an old phone you have, and you still want to use it, by all means ty it out, i guarantee a better signal as long as you use a long enough wire. When i switched to a thicker one, i got a better signal, but the battery cover doesn't close all the way, but that doesn't matter since i use a case and i don't notice it.

Haven't seen too many others comment about this, but I just thought I would share. After upgrading to a Seidio 1900mAh battery, my Evo 3D has been randomly shutting itself down. When I first got the Evo 3D and was inserting the battery for the first time, I noticed that there was a tiny bit of play after the battery has been placed in the phone. I looked at the contacts for the battery and saw that it *might* be possible, under certain circumstances, for the battery to not make full contact with the terminals. I only had my stock battery for a short time, so I didn't notice the phone power itself off, but that all changed after getting the seidio battery.
What I did to make the battery contact the terminals better was to cut a small strip of rubber band and place that so it stands vertically right below the SD card (it doesn't actually touch the SD card). After I did this, I placed the battery back in and it makes much better contact with the battery terminals and fits more snug, kind of like the OG EVO 4G had So far, I haven't had any random shutdowns since doing this.
i cut a strip out of a business card and put it in at the bottom of the battery(opposite of the sim card) and that has been my fix. i was gonna try and exchange it for the problem, but the dent in my metal surround shows it has been dropped.

I'm not sure if it's an actual defect of the phone or the battery for the phone. If they manufacture the battery about 1 - 2 mm longer in length, I think it would fix the problem completely.

A loose battery connection can cause a lot of glitches,random reboots,slow charging,etc. The second week I had my E3D I noticed the battery was a little loose so I ended up with 2 layers of business card opposite the contacts. The way I see it, it may not help but it sure can't hurt.

I didn't notice that... my e3d charging at very slow rate. now I gotta check my just to make sure i didn't get a defeated one.
I think some of you guys missed that he's not using the stock battery.
After a couple weeks of fixing the loose battery, I can confirm that it does work like a charm. Every week, I would get a handful of random shutdowns which required pulling battery to get the phone back on. With my simple rubber band 'mod' I have only had the phone power down once, and it seems as if I am getting much better battery life as well.

Nope, shouldn't hurt the Evo 3D at all. I would highly recommend switching to a rubber band if possible. It makes the battery fit perfectly without any risk of scratching the inside of the device.

A loose or dirty connection is like putting a resistor in the circuit. The voltage goes down and the current goes up. So to me shimming the battery is preferable to a non removable battery and random glitches. Thanks for your concern about scratching,good point, but I could care less what the battery compartment looks like as long as I have a good connection.
I had the same issue with my aftermarket 3500 battery. I ended up cutting a small sliver of business card, placing it on the bottom and left side of the battery and then securing it to the battery itself with electrical tape. This way when I remove the battery to put my stock one back in (which is my daily battery) I don't have to worry about anything.

Sorry to hear about your aftermarket battery It's good that you found a 'fix' for it by making it more snug. How long have you had the 'fix' in place, and have you had any random reboots or shutdowns afterwards?

Yeah I just happened to have a huge bag of rubber bands that I bought like 5 years ago, lol. I probably shouldn't worry about it either, but unfortunately I am OCD about my phone, among other things

Thanks for you then for rubber .
i was going to change the phone to end of this proplem .
I just noticed that when I put my hand around the bottom of the phone my signal drops by 2-3 bars and as soon as i remove it, it goes back up. I can do it over and over again. Just out of curiosity I tried this with my evo 4g and the signal doesn't change. I've seen a bunch of people reporting that their reception isn't as good as other phones with the 3d. could it be the antenna placement just like the iphone 4?

I would recommend getting a bumper...
No, for real though, the iphone had the issue because the antenna was built into the actual outside of the phone, when your skin touched it, it would change the attenuation which caused the issue of poor reception. Our antenna is totally internal so this would not happen.
I think your holding it wrong. Seriously though I just did the same and was unable to recreate the issue. Might be defective.

I saw somewhere in another thread that the radio antenna is indeed on the bottom of the 3d. Dont know if thats confirmed or not. But it would explain the drop when covered by hands.

61% with nothing touching my phone.
70% with my hand covering the bottom.

I fail to see how this is like apple because EVERY PHONE loses signal when being touched. The problem with Apple's was that it dropped the calls.

Yes, without anything it's at 80% and once I grab it it drops to 30%. The antenna does seem to be at the bottom unlike the 4G which was on the top.
And calls drop all the time.

I noticed the same thing but wierd thing is sometimes it happens and sometimes it doesn't.
I could recreate it for 15 tries in a row but then I closed the internet browser and moved the phone a couple inches and the problem stopped.
I will keep monitoring the signal while I grab the phone and see what happens. But yes it did happen when I grabbed the bottom.

Its not a "known issue". It just so happens that this is a cell phone. Which has antennas. Which, when covered, loose reception. No way around that. Its the nature of cell phones.
Comparatively its like complaining that when in a lead lined room, you have poor reception.

The iphone issue was caused by them leaving the antenna exposed on the outside of the phone. Whenever you would touch it in a certain spot it would short it out and you would lose the signal.

While it may not be exactly like the iphone, could it be similar in the fact the antenna placement isn't optimal? I think that most people hold their phones toward the bottom where the antenna is where as on other phones like the evo 4g they wouldn't be covering the antenna by doing this. I just know I've seen quite a few complaints regarding reception so this could be a feasible reason why.
The wifi signal strength is normal and good before, and it becomes worse about one month before, the wifi signal strength becomes weak, I have tested with other phones. At the beginning, I think it is the problem of the MIUI, then I flash Cm14.1 to see, but the wifi signal strength still the same. Can anyone suggest any method?
how exactly did you measure wifi strength?
and what can possibly go wrong with weaken wifi signal?

I have already fixed the wifi problem with opening the case of the phone and put a soft metal clip between the two wifi contacting points and the antenna.
I think it is the problem of the aging of the the two wifi contacting points .

I did some search on the internet first, finding out that many ppl having the same problems due to the reasons of falling down the phone on ground.
It is easy, First open the case, then open the upper part which is with 4 screws. then remove it and you can see there is two contacting point on the upper right side.
They are are the contacting point for wifi.
Just use some soft clip to increase the contact area and install back the upper part. that's all

i hope you already solved the problem, but if not, try this out, it work for me at least now my redmi note 3 wifi keep connect and the signal increase, first open your phone back cover (you can use thick material such as guitar pick) then at the top remove 4 screws (one screw is hidden in the back of small mi sticker) then remove the black small cover, there at two contact point put something (for me i use aluminium foil, i take it from coaxial antena cable, cut small square or so put in there) that's it put it back, try to test it first before you put the cover back because a little bit hard to open the cover though. goodluck....

This works in Xiaomi Redmi 3S? I am with the same problem, but i am not sure how to open it and where are the part that i must put something in that two contact point.
This is a very weird issue. I had very good wifi strength before and with the miui updates the signal is very weak now. Redmi 2 and any other phone has better signal.
I have the same router than before.
But its strange that other ROM also has weak signal... Because redmi note 3 pro used to be considered a phone with wifi signal strength
I have my phone suddenly got low wifi signal. I try your suggestion, and it works. Wifi signal is as good as new phone.
I do both put paper under the pin to leverage the connection point, AND put aluminum foil to the contact point in the small black cover to increase the contact area. Not sure which action do the magic

The wifi signal strength is normal and good before, and it becomes worse about one month before, the wifi signal strength becomes weak, I have tested with other phones. At the beginning, I think it is the problem of the MIUI, then I flash Cm14.1 to see, but the wifi signal strength still the same. Can anyone suggest any method?
