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.
and
http://androidforums.com/samsung-ca...vate-death-grip-issue-similar-iphone-4-a.html
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.
I have taken a metal plate and cut an opening into the middle that exactly fits my smartphone. When I put this on my desk and put my smartphone in the opening, I get three bars instead of one.
Forget it, it was a joke. I have not tried it, and it would most likely not work. But I am dreaming of it, because I have the same situation in my home office and at work—only one bar and a poor, slow, stuttering Internet connection.
I did try various things, like putting my phone into a ring of wire, but that did not work either. But one thing did work and has helped me—I searched and found the best position at work. There is one place on my desk where I consistently get about two bars, sometimes three. If I move the phone just an inch, reception gets worse.
The position seems to be stable. Rain appears to weaken the mobile phone signal generally, but the best position remains pretty much stable, so I don't have to repeat the search on my desk every day.
Of course the best place for mobile Internet and mobile phoning is at a window, like leaning the phone vertically against the glass pane. But that is usually inconvenient, out of reach, out of sight, prone to the phone falling down, too far away from the charger or from the computer, what have you.
The trick to find the best place for the mobile Internet is Settings, About phone, Status. This command shows, among other things, the strength of the received signal in dB and asu. For both numbers more is better, but the dB figure is negative, so there a smaller number is actually more.
I have not found any equivalent indication for the Wi-Fi signal strength. There may well be an app for that, but since I am actually looking for improvements that can be seen in the signal bars, I have not searched for that. One more bar is my aim.
So that is my recommendation for now: Search for the best phone position if you are in the same unlucky weak-signal situation like me.
But now back to the original question. Is it really not possibly to amplify the radio signal by using some passive piece of metal? It could be used like a reflector, for example, similar to the parabolic mirror of a satellite TV antenna. Or it could look like an antenna itself, attracting the radio waves to the nearby phone. I'd be interested in this for both the mobile Internet and Wi-Fi.
i've seen some kind of mettalic sticker that u put behind the cover of your phone on some website/forum, it says it can amplify the signal, i haven't tried them though

That is snake oil. Any contraption that fits inside the phone cannot amplify the signal, because it cannot receive more radio energy than the built-in antenna. Or, in other words, if it worked, the manufacturers would all put it in already.
Theoretically it might be possible for a bigger structure to concentrate more of the radio signal onto the phone's antenna, but I have never found a solution, except for large devices that have to be put on the roof or on a mast. But even for those the advice is to prefer active ones, i.e. amplifiers.

Not necessarily. Yagi antenna design uses directors and a reflector to amplify the signal to the driven/main element...yet they are not physically connected to that element.
At the frequencies used by cell phones, the directors/reflectors would have to be VERY close to the main element.
But placement is critical. Just slapping a contraption in the case would be hit or miss. Unless you knew where the antenna was and were able to place the decal properly in relation to that antenna, it might do nothing or even degrade reception.

Actually, they do...sort of. The engineers who develop cell phones take the shape of the case and placement of components (including the antenna) into account. They have to: The device has to pass MANY tests to conform to FCC regulations (and other countries if they want it to be usable worldwide). The internal structure of the phone is designed to shape the radiated signal and conform to regulatory standards.

You are right. But then the Yagi antenna is a big thing that requires some space much bigger than the actual antenna element.
But I agree that, if the phone is in a particular position in relation to the tower and some piece of metal is perfectly shaped and placed, it may actually enhance reception a little.
In most practical cases this is difficult to accomplish. The phone is held in various directions, for example. I guess that placing the phone in an optimal place and position, like leaning it against a window pane, yields a better result without any special antenna enhancer element.
That's what I am actually doing with moderately good success. I will probably change providers soon though, which will yield a much bigger enhancement, as the new provider has a tower around the corner.
So I got the Moto Z for my birthday, September 19th, and today February 6th I have to consider the phone as dead, as there's too many problems with it..
First problem I had with it, was the vibrator, it made a noise as if it's rubbing against the chassis. This happened after about a month and never went away.
It was problem free for the most part, up until after Christmas, when I put it in my pocket, went for a walk with the dogs, pulled the phone out mid walk and.. The screen was cracked.
A single hairline crack from edge to edge.
I've noticed the glass lifting off the frame on the right side, and so I believe the battery is swelling up and this caused the crack.
There's no pixel damage, but after this all kinds of problems have been surfacing, the screen won't always turn on when someone is calling.
The bottom proximity sensor won't always wake the screen any more.
The finger print sensor is made of plastic, and is now so scratched that I have trouble unlocking the phone with it.
Battery life was never even half decent, if I didn't charge it to and from work I couldn't make it last 12 hours.
Now it's even worse obviously.
Phone can die at any time when it drops below 10% charge, like no "shutting down" notification, screen just goes black.
Connecting the charger it'll go from 0% to 15% in seconds, or take 20 minutes to even boot again.
The ringtone/earpiece speaker has cracked, and is completely unusable now, at the very lowest volume there's a marked crackling noise, turning it up you can't hear what people say on youtube or when making calls.
The magnetic compass has never worked right, it'll make large jumps when turned south, by about 20 degrees west or east.
Makes playing Pokémon Go quite difficult as it'll jump uncontrollably around the south mark.
Occasionally the map will just keep rotating until you make the calibration movements 2-3 times.
It'll drop 4G connectivity and the reception is about half as many bars as my Moto X 2014.
The frame was bent when I climbed up a attic ladder, so the aluminium quality is rubbish. (A few weeks after the self-cracking incident)
I tried contacing Lenovo, but they won't take the battery for warranty as the glass is cracked, the fact that I tried telling them the crack is because of the battery was left on deaf ears.
My wife's HTC One M7 had the same thing happen after 11 months and they replaced the entire phone no questions asked.
Lenovo didn't keep the hardware designers, and is simply trying to churn out a few Lenovo phones with the Moto name before the brand name is truly dead.
In conclusion; Motorola is dead. Don't buy this phone.
You maybe got a bad one, it can happens. I also have the Moto Z and I use it everyday with my moto 360, I bought both like 3 month ago. Also I'm on Nougat and I don't have any issue that you describe, the only thing I also notice is the phone auto shutdown but below 5% which I find normal to save the battery, other phones maybe shutdown at 1% but in fact there still a couple of % more left.
Wow that sucks. Sounds like you got a dud. My Z has been excellent. battery has been amazing and haven't had any problems with the vibration motor.

Same here. I've had it since November and no problems at all.
Hahahahahahaha That was a funny post. It was satire right?
I've had 4 Moto Z's and loved them all. 2 Verizon variants, 1 Verizon Force variant, and one US unlocked. The frame on this phone is incredibly sturdy as seen here:

All of the damage to your phone has nothing to do with Motorola and everything to do with YOU. Phones don't damage themselves, the speakers don't crack, the fingerprint readers dont scratch themselves, it was you. It sounds like you trashed your phone and now are trying to place blame on someone else (Motorola).
For you to come in here and tell everyone not to buy this phone is absurd. Like I said, I've had 4 of these phones and not one has shown any problems at all. The problem is yourself, not Motorola, not Lenovo, not self-shattering glass, and not self-scratching metal.
You dropped your phone down a flight of concrete stairs and it fell end over end bouncing on every step on the way down. It cracked your screen, scratched your fingerprint reader, jarred your vibrator loose, cracked your speaker, and uncalibrated your compass. Lol That's what happened.
PS the proximity sensor can be finicky. That's the one thing I'll give you. The rest is "rubbish".
BTW, that "sudden shutdown" I experience on my G5, too and it's really bad. After 10-12 it gets down rapidly and sometimes it takes only 30 seconds of usage for the phone to shut down after you are 10%.

The battery expanding, cracking the screen, and causing the phone to shutdown randomly at or below 10% should be replaced as a defect. He has a good point with that part. But unfortunately in the warranty it specifically states everything to do with the battery is not covered under warranty. Pretty sneaky way of Lenovo to basically *not* warranty this phone because the battery is locked in and part of the whole construction.
I have to agree, if you haven't bought one yet, don't do it. I do like this phone for its features and mods, but it is designed to be completely disposable. Prices of phones with locked in batteries really should be half the price of what they are.
Dude you need a Z force
If I couldn't have a Force and camera wasn't a huge issue, I'd get a Play. I see no point getting a Z if you can get either the Force or Play unless you just want a really skinny phone.

Why would I lie?
I'm genuinely sad, this was my birthday present (to myself) after a really long wait, as I couldn't afford the 2015 model last year.
I haven't mistreated it, I've been super careful.
I've been a Motorola fanboy since the V3i, owned most models since then.
Based on teardowns, it's built like a Lenovo device, and that confirms it for me at least that they've probably fired the old chassis engineers.
I know it's a bit ridiculous, but I feel a bit lost now, I want a new smartphone, but there's no other brands I've ever enjoyed..

I'm still using my Moto X (2014) and similarly consider the Moto Z (dual SIM preferably) as my only attractive upgrade.
I empathize with the poor experience you've suffered with it, especially as it was a birthday gift. However, I suspect that your experience is the exception and that you received a dud. It happens. And although Motorola's warranty and customer service seem very poor, perhaps you might consider repurchasing when prices drop after the new model is released. I am currently researching root and other support options for the dual SIM variant before "pulling the trigger" (on eBay)...

You bent the frame, you either leaned on something, or if your pants were too tight, just compressed it too much. It's crap luck, but it's not motorola's fault, nor is it a warranty claim.
Your battery would only expand enough to crack a screen if it were very highly overheated. like, shorting out overheated, in the 80-90 degree range, basically hot enough that you would have had second and third degree burns in your pocket (battery expansion occurs at about 90 degrees on average in lithium cells, there are many, many, many studies on this subject, especially since Samsung last year)
The finger print sensor is made of plastic, and is now so scratched that I have trouble unlocking the phone with it.

Stop carrying your phone in a pocket filled with change?! or something? I've had my moto Z the better part of a year, and my fingerprint sensor is spotless, I can't even imagine how you scratched yours.
Phone can die at any time when it drops below 10% charge

Do you know how lithium batteries work? 10% across 6 cells mean each cell has less than 2% battery.... at less than 1% you do irreparable damage to a cell, it will never take a full charge again if you drain it completely. So unfortunately, 10% is actually a completely reasonable number to shut down at.
Speaker breaking? No idea how you accomplished that, usually take a pretty solid impact or water damage to blow a phone speaker to the point of cracking even at the lowest volumes.
Reception wise, I'll admit mine shows less "bars" but remains connected regardless. It's less about not having signal, and more, appearing to have less.
I will agree, the compass isn't the greatest, it's easily calibrated though (using google maps)
Sound like you bent your phone, and if you hadn't, you'd have a warranty claim on the speaker, and "possibly" the battery. But since you broke your screen, you're screwed. You SHOULD be able to send it in for repair and pay them to fix it/replace it, usually for much less than the cost of replacing it.
Sorry about your luck mate.
I decided to follow up on this review with my one year review of the phone.
So far I have none of the problems you have listed, and I'm very careless with my tech (Read: Broken every single screen on every phone I have ever owned)
The only complaint I have is that the finger print sensor gets dirty easily, though I assume that's more likely a mix of the finish on it and my fingers getting oily.
Battery life is meh, but I have the battery mod so no problems yet (2-3 days usually with my usage, as opposed to the Xperia X being 4-5)
I do have one problem with your review, apart from many of the problems seeming self inflicted, this one particularly stands out.

This sounds like a manufacturer defect.
That should've been the moment you asked for a return or warranty repair.
Hello, everybody! Do you often wonder whether or not your smartphone is survived a drop? Of course if screen is not cracked, and everything else is still works, then you are safe! Well, maybe...
The question now is about internal damage.
I've read a lot of similar threads here about drop damage, internal damage etc. And also read a lot of scientific articles about drop testing of PCB (printed circuit board), to find out how easily some chip on phone motherboard can be knocked out (all of us remember iPhone 6 Plus Touch Disease).
There is also JEDEC Solid State Technology Association's Standard "Mechanical Shock JESD22-B104C". This documents postulates standards of drop testing for consumer electronics manufacturers (who manufacture electronics wit solid state components, such as processors).
And eventually I figured out a number of statements that may help to find peace for all who dropped their phones:
1. If there is no visual damage on your phone, check if everything inside works as usual (to find internal damage):
a. Touch works everywhere on the screen.
b. Cameras works and focuses properly.
c. Speakers (ear and bottom) are fine.
d. Vibration motor sounds as usual.
e. Accelerometer, gyroscope, compass, GPS, cell reception and download speed on cell or Wi-Fi internet are fine.
f. All buttons and ports are good.
If all above is OK, then there may be no internal damage. Keep an eye to your phone a few weeks after, because internal damage (as microscopic cracks in solder joints) could develop itself not right after impact, but during following hours/days/weeks. If it doesn't, then you are likely safe!
Main conclusion: If any internal damage could show up it will definitely show up in next several weeks after drop. If everything is still OK at that time, then there is likely no internal damage.
2. Smartphones internal circuit boards in general are designed to withstand human height drops (1.5 m or 5 ft.). Of course, bad luck happens, and such drops could smash buttons and screen, but in most cases internals of phone will survive. Here we talk about proper manufacturing conditions, proper soldering etc. Drop stress itself not as dangerous for circuit board, as bend stress. Bend stress is the worst for soldered chips. And bended iPhone 6 Plus Touch Problem is the good example of that.
You are welcome to discuss and I will be glad to hear your thoughts and observations!
Hi everyone, recently I noticed that my Xperia XZ was a little bit twisted on two corners however, I'm too carefuly everytime, I never save it on my back pocket, every time I save it in the front packet and I have Rhinoshield PlayProof protector. So the question is, are you Xperia XZ bent too? The bent on my phone isn't possible to see, the way to check it is pushing your finger on the 4 corners (1 per time) and if your phone moves a little bit, it's bent.
Ahm, define bent, provide pictures if you have to. Flat and pretty much pristine here.

I have the same issue on my Z3 from carrying in my front pocket. Bending it back is no problem.
there is no need to open another thread about bending...we already talked about it...let me explain something...xperia xz is made mostly from plastic and some aluminium back cover and its prone to bending...i know that flagships should not be that way ,but maybe sony made something new with the xz like bending ability (joke) at the end it can be a good or bad thing. i think they went for plastic design because of overheating processors.Sony simply cant make a phone that wont overheat...this is still there biggest problem to solve and also chips are going only to be better and better so more power with more heat will come and Sony again wont be able to manage that.we will se what will happen
mine is bent a little bit
always carry it in the front pocket of my jeans
see no problrm with it

The hybrid (polycarbonate, AL- alloy) structure was chosen for radio related purposes, heat expulsion has nothing to do with it; as a matter or fact, polycarb is a quite decent heat insulator. Now to the problem at hand, it takes a considerable amount of force to bend the polycarb frame, as for the Alkaleido back-panel is quite easy. I usually keep it in my pants front pocket, not a problem so far, +6mo user.

I tried the same with my blue XZ, and yes I have same issue as you. But I use a case so do not notice it.
On my phone, its the bottom left corner that is raised compared to other three. I'm guessing its lack of quality control (and care) by Sony. That's why no other flagship since Galaxy S5 (back in 2014) is made of plastic.
xperia phones were always known for having a bad wifi coverage...i know this cuz i had xperia Z,Z2,Z5 and now XZ and all the same...also i had sgs7 for 4 months and before all of those phones i also had sgs3 and i can confirm that xperias simply cant compete with Samsung in wifi coverage ,there chips are far better.the solution to this is get a wifi extender, atleast for xperias LOL

A sample size of one person isn't enough to declare a widespread problem. It's just as likely if not more so that it's something to do with your own setup or your unintended biases.

The number of bars is *completely* meaningless, as each manufacturer determines what these arbitrary bars indicate for their own device. A one-bar rating from one manufacturer could easily indicate a stronger signal than a three-bar rating from another manufacturer. If your XZ can't hold onto a 2.4GHz signal from two rooms away, you have a problem, either with your phone or with your network and environment. Mine is fast, snappy and has 3/4 bars on both 2.4GHz and 5GHz networks when easily 100 feet from the router with at least four or five walls between phone and router. (Just checked and as of right now I have four bars on my 2.4GHz and three on 5GHz in precisely these conditions in a location with ten networks currently visible.

A sample size of one person isn't enough to declare a widespread problem. It's just as likely if not more so that it's something to do with your own setup or your unintended biases.

u probably understood us wrong...so let me explain it this way...first its not about the wifi bars cuz they are like u sad in ur comment relevant from manufacturer to manufacturer...now let me give u an example: i leave in 34m2 apartment wich has 2 rooms separated and when i go to toilet and thats about 5-8meters away from my Asus router... so tell me how the hell i loose signal... are u going to say that i leave in a bunker it berrarly stays on single bar and it disconnects everytime i move the phone a bit so i have to catch the signal by moving it about meter towards the router.With other branding phones i dont have to do that...even with older ones. All i want to say here is that in my experience i have these issues but im not bothering so mutch cuz it can be solved quite cheep buy buying a wifi extender and also it comes in handy for other opertunities. peace folks
I was realised the issue at the early of the April last month. I bought my Xperia XZ since May 2017. This issue had caused my screen glass poke out and cause the proximity sensor not function properly. After put the phone on a flat marble table I realised that my phone was bend. I thought this might be some hardware problem or probably is battery faulty, then I sent my phone for warranty. The Sony Service Centre managed to change a new frame case as well as the back metal case. Now the phone is no more bending, but the screen glass will poke out when the phone overheat as the service centre did told me this is because of the defective waterproof glue.
