Terrible connectivity - Galaxy S6 Q&A, Help & Troubleshooting

I've noticed that my S6 consistently shows fewer bars in my neighborhood compared to my S5, even often going down to 2G in the center of Amsterdam. This never happened on my S5. GPS positioning is also awful. Standing still my position keeps on moving around while with the S5 it was spot on.
I think the new aluminum border blocks the different antennas. #antennagate

I'm having the exact opposite. My phone hasn't dropped into H since I've had it, my Nexus 5 would all the time.

Antenna Issues?

So I read that and it sounds a lot like an Apple iPhone lover trying to find fault in this phone. Anybody who owns the Captivate, can you possibly check this and update us on this ?
I'd read the comments for that article.

The issue can be replicated on almost any phone in certain conditions. Its really not an issue to be concerned about.
I've noticed that my Captivate is hovering around 2-3 bars constantly. It rarely hits 4 or 5 bars unless I'm right near a tower.
I have the body glove case on the phone as well and this is still occurring.
Mine shows 4 bars on the table, in hand it drops to 3 bars. If I press it into the palm of my hand and put an actual "death grip" on it, it goes to 2 bars. Nothing to be concerned about as far as I'm concerned.
Looks like it is an issue, possibly worse than the iphone 4. There's a new test on youtube about it. I can't post links until my account is verified. Search "samsung captivate." Many phones are tested (captivate is around the 5:20 mark):
It dropped from 3 bars to zero. Yikes! Still though, this was a very tight grip test, which no one uses. I would like to see just a casual grip test. According to at least one video I saw, on the iphone, if you put just one finger on that spot on the left side, it will drop.

Is it this video? Don't be too concerned with the bars. Bars are just a vague estimate of signal strength (it's probably gamed by the manufacturer). I'm interested in real-world performance. There's another video on here (or maybe androidforums) where a user shows the bar drop during the "death grip" and then runs speedtest.net to show that the downstream performance is almost identical. If the data performance suffers or I drop calls when I hold the phone, it's a problem. If all that happens is the signal meter drops a little, I don't care.
I'd be interested to see if the issue Techno Buffalo had can be replicated on the other Galaxy S devices. IIRC, the Captivate is the only one with a metal back cover.
Yeah, that's the one. Good point about the bars...
Like the iPhone 4 it's not really a big deal. Most people will never replicate the circumstances needed for this to happen in daily usage and the ones that do probably will do it on purpose to make a stupid video......

Seriously. Who holds phones like that? I love how he was dragging all the widgets around on the Evo with his palm. Hulk no get reception on Hulk's iPhone 4. Hulk smash!
I've tried holding my phone in 20 different ways and cannot make the signal go away. The problem with the iphone is NOT the same as just putting the captivate under something so it doesn't receive the towers as well. Captivate is fine.
All phones lose signal in a phone specific "death grip". The difference between a well designed phone and the iphone 4 is how awkwardly you have to hold the phone to lose reception. On the iphone 4 you lose reception holding the phone in a way that is normal for many people. Well designed phones don't lose reception while being held in any natural position.
I held mine the way you naturally would in the left and right hands and saw maybe a 1 bar drop out of 10 tries.
If you completely cover the back with your hand you can make it drop a couple bars (but no **** why wouldn't it you are covering the entire back lol). And by 'a couple' I mean exactly 2. Thats the most I could get it to drop any way I held it.
Also if you grip the bottom nice and tight, and make sure that your palm is making 100% contact with the back you can get it to drop 1-2 bars.
I made 10 test calls with the captivate and the most I can make it drop is 2 bars, and even when I dropped from 2 to zero bars it wouldn't drop the call.
As long as it doesn't drop the call I don't care how many bars it shows. Also I think that they are calculating signal strength based on data (upload and download) and voice. From what I saw I think the bar drop is from data upload speeds decreasing.
I'd like to hear if anyone can actually drop a call from this. I can't but service is okay where I am lowest I hit was 2 bars without the grip.
i get 4 - 5 bars normaly. When i apply the death grip i drop 1 bar... btw the death grip you give an iphone 4 and a regphone is totally diff. The deathgrip for the iphone 4 is casually holding it in your left hand. For normal hands one is required to strangle the phone. With the extreme death grip i got it to drop one bar. I have huge hands too...
I don't think the problem with the iPhone 4 is the normal attenuation problem you have when you put something like your hand over an antenna to attenuate the signal. With the iPhone 4 you are actually physically touching the phone antenna and shorting it with the other antenna using your skin as a bridge. The "death grip" for the iPhone 4 can be as simple as putting your index finger across the black gap between the antennas on the lower left corner. That's why Apple's $30 rubber band works.
I've been in high-signal areas all day so I haven't really had a chance to see how much of a problem the signal drop is when you have your hand over the bottom slider plate. I lose 1-2 bars, but I'm not getting any statistically significant difference using speedtest.net.

Not getting Edge?

Usually you have edge whenever you have signal right? My dad has a G1 and usually has edge anywhere he has signal although my g2x usually only gets edge when around a 4g zone. Whatsup with that?

Stupid Stupid antenna

I received my replacement back cover today in hopes that it would resolve my signal strength issues.
It doesn't. My sensation loses signal if I hold it normally. It gets reduced signal from using any case/cover as well. I get 1-2 bars and if I leave it in my pocket at my house, I lose signal all togther.
My father has one and the same issues as well, and my cousin has the same issues.
With other phones, MyTouch 4g, Motorola Cliq, etc, We have 3-4 bars all the time, no matter what.
The antenna on these is poorly designed, and it could be complicated by software/radio configuration.
Just wanted to let people know that getting them to send you a back cover may not solve your issue.
I think I'm going to send it back for service/testing, but I'll bet it passes and they send the phone back. If it only works 10% as well as you think it should, but 10% is 100% of their spec's, then 10% it will be... HTC may have lost a customer..
Have minimal WiFi antenna attenuation, and it hasn't affected my usage, at all. And I mean :::zero::: You will be okay. None of the Sensation handsets have 'better' casings than others. Honest.
you're pretty lucky. considering I haven't had this issue ever since I got my sensation. but its the unbranded one.
Id guess something is wrong with your hardware, inside the phone. I hold my phone funny and still have great reception. Heck, I even put thick lead sheet in the way of the antennas and still had good reception!
Id do an exchange.
Matt
It's not the back. I had a sensation with dust under the screen. Got a warrant replacement (just the front), and now I have the death grip issue.
Sent from my HTC Sensation 4G using XDA App
Maybe.
I think I'm going to send it out, but if it's all 3 (purchased at different times from different places) then what is the issue? It drops some bars if you hold the phone. Even when you don't it is lower bars than my Motorola cliq)
I'm pissed. If they tell me nothing is wrong, it will be my last HTC.
Uhmm daaa.. Do you read instruction mannual? Dosent read shh... and posting dumb things.. EVERYTHING about anntena is written there.. the operator antenna is at the bottom of the phone! (there are little holes at the back cover) so avoid covering the holes and it should be fine! - Because as you probably noticed the wifi & operator antenna is the little gold plates on inside of the cover... and thats why you get 'death grip' when you cover them... - Basicly 1/3 of the cover WORKS AS AN ANTENNA! So no replacements will fix this.. it is just the way it is!
When I cover the antennas one bar dropes for me, but thats it... Of course when i pull the cover out i almost have no coverage(because no antenna is connected)

Poor Quality Control?

What's the deal with the S8+ and inconsistent quality control? The first one I received only had one flaw, the WiFi constantly disconnecting and reconnecting. The second had the red display issue and the SD card slot decided it was going to stop working properly. The third has a green discoloration down the left side of the display. Now I have a fourth incoming and frankly, I don't have high expectations of it. I've stayed away from Samsung's phones since the S5 and now wish I had continued that trend.

Millions of S8+ owners phones are perfectly fine. Someone had to get the few lemons. Sorry you seem to be one of them. That said, quality control has been very consistent.
It could also be because of the Note 7 burn fiasco. Because they're worrying about the battery issues of the past, other "smaller" issues popped up (what I mean by smaller is that your issues won't get the phone banned by government agencies). Sorry about the bad seeds, although, thankfully, at least Samsung is also tossing out software fixes pretty quickly.

Lost some bands on the way?

Hi all, my N5 dropped in water some months ago, I was albe to save it because it was in my jeans pocket when it fell, so no direct water in circuits, but only a heavy load of humidity.
Anyways, after months of regular use, it suddenly stopped to have good signal in zones where it is more difficult, because of low signal. No problems in open field with good signal. I observed a similar behavior in a Xiaomi without band 20. Can the water have damaged the modem, in a long term way, after the drop, losing me only some bands?
Or one of the internal antenas. There are two wires on each lateral edge of the device, one might have become desloged/corroded.
Only option is to open it, it's not so hard...
