Anyone know SAR(Radiation level) in Motorola defy CM7.1...Because when i am making calls my fingers r getting shocks and getting sick by talking more..
LOL man either your handset is faulty... or you read a few scaremongering articles about the dangers of mobile phones and it's all in your head.
Now, two things. One, this should not be in the development section. Two, it's a question you really could have resolved yourself.

really? this such thread ended up on Development section?

No phone can ever emit enough radiation to actually make your sick so soon. Shocks have nothing to do with radiation either. So send your 'shocking' defy to a service center and go to a doctor for your sickness

I am scared of radiation. Our heads are being baked constantly not only by phones but almost every electronic device. I hope we find something better than wireless communications.

Your head is thousand times more baked by the NATURAL radiation of the sun than by your phone or even your microwave. Up till now i've never heard of anyone dying of sun or cosmic radiation in 2000 years
Sent from my 1Ghz CM7 + CM9 Defy
Have you ever held an iPhone? I bet you did. If you "felt" the Defy's radiation, you would probably died from the iPhone's radiation.
Anyway, the SAR level ranges from 1.52( body ) to 1.53( head ). Courtesy of Google.
People really have no clue when it comes to radiation, its different forms and how one can 'bake' with it.
Electromagnetic radiation in the area of radio waves simply is incapable of inflicting damage, especially at the very low intensities our devices are emitting. Microwaves are capable of heating substances (most notably 2400 MHz waves in your microwave oven) but for that we need hundreds of Watts of power. Your phone with wifi - around the same frequency - might be able to heaten up your head by a tenth of a degree. Just sitting in the sun or next to a heating radiator - oh dear! - has a much greater effect..
Visible light, also electromagnetic radiation, has a much much higher amount of energy than radio and micro waves. So if you are really worried you better stay indoors during the day, and full moon nights too.
When we raise the energy bar even higher we end up at UV, x-rays and the such. Then and ONLY then one has to start paying attention because those frequencies can conflict physical damage to DNA, tissues etc, which is a TOTALLY different process from heating up water in your microwave. A little heat never caused cancer. Well I hope not as I am living in the tropics. Now the only relevant x-rays on this planet are men-made in controlled environments so nothing to worry about there. Leaves out the UV radiation. Well yes THAT can cause skin cancer. No surprise there I guess.
People should stop talking nonsense about radiation when they have no idea what they are talking about.
When ever i receiving or making calls my ear is paining if i talk for 5 minutes i am trying to end call in 1 minute sometimes i even getting shocks to my fingers when i am on call.. Is there anyway to reduce signal strength.. Please help me.

Dont use Mobile phone...
use some headset or bluetooth device,
make your phone far away from your head
trust me
Try another baseband. This might reduce your signal strength. Use Baseband switcher for this,,,
I tried other baseband too least is 850/1900 and when i using that i cant hear other's voice.. Previously when i use samsung or Motorola i never received such high signals.. Thanks for your reply guys..

when trying the other basebands you can't swap the frequency range that the phone is receiving ie using 850/1900 when the phone is built for 900/2100 as the radio is not tuned to that frequency, also the service provider may not operate on that band,
teamwork makes the dream work
Even when i putting i my pocket i feel my thies and other parts feeling pain with that radiation i dont know how many observed it.. So finally came into conclusion to use headset, keeping far away from ears, not to use phone much and better try to hold in hands not in pockets and there is no alternative application or procedure to reduce signal strength.. Thank you guys
You have a faulty Defy.....
Just send it for service

Does anyone know of any radar detection program for windows mobile 6 ?
I'm talking of the radar that traffic department use to detect you speed on the road. I know gadgets exist that detect the devices and give you early warning. iv'e heard the nokia phones have such a program, does anyone know if one exists for windows mobile phones ?
Use TomTom or something similar....

Yes i am talking about the live instant radar devices. the guy standing on the side of the road with the radar cam.
NOT the permenent camara's.
I need the phone to beep and warn me when a radar device is in close proximity.
Oh God... you can't be serious...
Re the nokia phone, check here:
http://www.warp2search.net/contentt...ia_mobile_phone_as_a_police_radar_detect.html
It's been proven and proven again - it doesn't work... The only part of your phone I could see somebody trying to say would work is the IR receiver, but IR and RADAR are two ENTIRELY different things. And even if your phone could detect RADAR or Laser (which, again, none can) - you'd have to place the phone somewhere on your windshield to make it useful - and given the Hermes configuration, you'd have to have your phone horizontal... Even if it did work, I'd not want the thing sitting all goofy in my windshield.
With all due respect this is one of the goofier requests I've ever seen on here.
In other words - buy a radar detector... A half-way decent one can be had for under $60

I had no idea, that this joke from early GSM will resurface again in PDAs. The only other popular GSM lamer-tester I know about was Polish invention of "marupy zwrotne" ~ "return/confirmation marupas" (yes, it makes no sense in Polish neither, but sounds... dumb and probable at the same time).
Do you know of any other gossip/fake GSM/PDA services that were used to joke of not-so-bright users?
Sorry, i think, that if you want to use the Hermes as radar detector, you can use it as microwave oven. The WiFi module works on 2,4 GHz like the oven too.

Just the whole horror story about cell phone towers in residential places has no scientific basis at all. The same people scaremongering about this stuff are probably responsible for this one:
In scotland a plan to build a wind farm, 10 or so wind turbines, was refused due to concerns by the local community about the risk of radiation!?!?!?! WTF!!!!!
Besides the mobile phone<->tumor thing has been disproven many times by (independant) scientific study, the public always go along with these STUPID rumours.
Of course it's stupid as hell. Why those people still use TV sets (after all CRT and plasmas are quite effective x-rays lamps), electric engine-based household devices (this is really powerful electromagnetic source) and microwave ovens (that in fact are causing problems with WLAN and some cell phone devices). And what about those electric cables in the walls? Slightly exaggerating those are giant antennas emitting 50/60Hz waves at very high power.
So if you (the reader, not mrvanx of course) are anti-cell phone tower activist, start with canceling you contract with company that delivers power to your house. Then we can continue talking.

Remember the email that said you could unlock any car that used a remote keyless system?
http://www.snopes.com/autos/techno/keyless.asp
the original point
regarding the RADAR guns that law enforcments use...
(i know about this i have 11 points on my license (3 have already come off once) and done the speed aware ness corse)
i do beleive they use a few different devices and on different frequancies, the devices you have in your car dont always detect the RADAR and they also change progressivly so you would need to keep buying the latests detectors... not to mention if you are speeding and your detector (even your phone is you got it to work (not likely)) picks up a signal and warns you... its already hit you the gun already knows how fast your traveling and its all too late!!
there are devices that emit a scramble frequancy and the copper will just get ERR on the gun but again they change the frequancy or method (lasers or RADAR) and your still boned and in UK if your caught with one of them you can then be prosicuted for preventing the corse of justice...
all in all its not worth it... the Tom Toms and the likes have notifacations for fixed cameras and 'black spots' were there is offten coppers park (this doesnt mean they wont change spots and they might never be there as you drive past but thought it was worth a mention)
If you want to find radars open your nostrils... They usualy smell like onions...
Cheers and good luck.

Hi! I just got my TP2 and found out that it has very high SAR-value for body. Numbers in my package are: Head 0.68 mW/g10g and body 1.87 mW/g10g. For examble my previous phone HTC Tytn had: head 0.572 and body 0.663. I don't know if these numbers are something to worry about but it's kind of weird that this TP2 has three times bigger body sar values. By the way I live in europe so the measuring methods - I think - are different in states.
Maybe somenone can explaine what all these different numbers mean. Because in http://www.phonearena.com TP2 values are 0.50 (head) and 0.82 (body) and for Tytn 0.82 (head) and 0.69 (body). I just can't make these number match even though they are measured differently but for example Tytn head number is bigger than TP2 in phonearena and in my packages it's quite the opposite (Phonearena TP2:0.50, TYTN:0.82 and my packages TP2:0.681 and TYTN: 0.572). I don't know if these phonearena numbers are correct but this is kind of bothering me.
Maybe someone can clarify this for me. Are those numbers high or not, cause it seems to be almost impossible to compare these numbers.
Oh this was the first message from me to this forum.
It would be funny if you read this numbers drinking vodka and smoking a good cigarette...
Man, take it easy: You will not die due to a mobile phone.
Just my two cents.
As above, chill out im sure it wont be THAT bad for ya
Think of it this way: Each day more and more and more things are found to be carcinogens, things which you live with no prob, with which many people live with. If you're going to fret over each and everything, you should buy a big plastic bubble with hospital grade air filters and put the ventilator far away from the bubble in case the electromagnetic fields could do some harm. Oh, and don't forget to live somwhere where there's no sunlight, not too much damp, nor dust, etc.
I'm not making fun of you, but rather the paranoia which has permeated society. It really is funny when you read the list of all possible carcinogens, some are just ridiculous.
Remember, using antibacterial soap on a regular basis is bad, and I'm guessing it's worse than using your TP2

Okay, I can see that I didn't really get the answers I was looking for but thanks anyway. Maybe I'll find another place to ask these questions.
By the way, in many countries they have already suggested or are planning to suggest that children should avoid using mobile phones too much and prefer sms. Yes, it's true. It's because longterm effects of using mobile phones are still pretty much unknown (simply because mobilephones hasn't been availebto too long yet). I don't know if it has anything to do with the reality but I guess that's the problem, nobody knows yet.
Anyways, thanks for funny answers. I rest my case here. By the way I am writing this with my TP2 and feeling just fine.

It cames in a attachment document inside the box of the HTC Pro2.
High Sars values should be taken into consideration. The higher the values the more power it uses, therefore generates more heat.
What i don't comprehend is how come the body sar values are much higher than the head.
Imagine having that by ur balls lol it will fry ur sprem
one thing is: These values are the Highest Number of SARS reports, therefore the closer you are to reception and the less your phone has to work, the sars will be lower.
but if you are in a area that requires lots of power than well it's going to reach high levels.
Next time I will take in consideration the fry sperm...
"Honey, I have a new "bed cooking speciality", just for you..."
Well, it's still below the SAR value limit. And as for frying your sperm...
Just where exactly do you put your phone?
personally I keep my phones in the pocket which happen to be at either side, not in my briefs

The SAR values are included in the manual.
What he means by an area that requires lots of power is an area with poor reception. Poor reception means the phone has to work harder to maintain communication, ergo the higher SAR value at those times.
you want lot SAR ? - get an HTC Universal, it's like 0.177 thanks to the display assembly being between you and the antenna that's on the back.

Hi Everyone,
I'm a software/hardware student in college and I thought I'd post my idea here and get answers/feedback.
I would like to write/code an application to use my cell phone to output white noise and jam other cell devices (basically jam 850MHz,1900MHz) in my vicinity. I have a Sprint HTC Touch pro2 and have SIM, Radio, and Hard-SPL unlocked it.
Programming this would require a lot, so I'll just ask the community the basic question: Is this possible? How easy would it be to write it?
Any feedback and answers would be great. I'm sure this is an open/shut case and it will make me look completely foolish if it's not possible, but positive reasoning is appreciated.
Thanks.

Thankfully, you can't. Why would you wanna do that anyways? There's a lot of bugs to be fixed and apps to be written, why don't you use your 'skils' in that direction.
No offense, but I'd hate to be within your area and need to make a 911 call only to have my signal jammed.
As the person above me posted, use your talents to help move forward some things that MS has let stagnate. Use your talents to write an app that will send an amber alert at the touch of a button. Your skills can be used to create a program for people like me, with a medical history, and all I would need to do is push a button and a In Trouble alert would go out to a pre-set group of people in the event that I am in anaphyllactic shock and cannot breathe...I'd LOVE to have something like that on my phone.
The point is, just because you may be able to do something doesn't mean you should. Lets say you did somehow create that program and someone died because of you and your program...yes that is probably an extreme case, but wouldn't it be better to use your talents to HELP.
This would be highly illegal to do first of all (at least in the US). Also you'd need a much more powerful transmitter, afterall it's your phone versus a dedicated cellular tower. I'm going to guess that sending enough current through your phone to output that much noise would absolutely fry the electronics, if not at least destroy the battery.
Here in the US, there happen to be federal laws against doing exactly that.
"Willful interference with the lawful transmission of a radio signal", I believe.

So when the theater catches fire nobody can call for help?
Yes, yes, we all understand that idiots who can't silence their phones and stay off them in inappropriate settings are infuriating. This is still a terrible idea.
Let's say I'm on-call, which in my case is 1/4 of my life. I decide to risk going to the movies, and set my phone to vibrate in case the hospital needs to reach me. They send a text message, so I can discreetly pop out in case I'm needed - it's no different from someone who wants more popcorn or needs to use the toilet. Wow! I make it through an entire movie without being interrupted, or so I think until I get to the car and a flood of messages and missed calls suddenly appears on my phone.
Unfortunately, I had no way of knowing some moron had illegally blocked cellular signals and sat through a movie while your mom was dying in the ER. Are you going to cut me much slack for not having responded to 114 messages while the ER was desperately trying to get in touch with me?
Didn't think so.
Thanks to everyone for the replies, regardless if it's possible or not. I did not mean to start a moral war or argument. All moralities and emergency-call situations set aside, it would still be fun to make IMO.
I've been looking online, and if you wanted to properly jam all cell signals, you'd have to jam a range (824MHz - 894MHz and 1850MHz -1990MHz have to ALL be white-noised to accommodate for duplex cellular communications on all US voice uplink and downlink frequency signals). I think that with the range it would have, I would notice an emergency occurring close enough to be able to switch it off for people to make emergency calls.
Yes, cell phone jamming is illegal to use in the US, but is not illegal to possess (like illegal narcotics). I looked online, and the actual legal violation you would be charged for is a property-theft-related charge, since carriers purchase frequency bands as property for use in locations they pay for, and you'd be shown as stealing their property. I'll have to read the . I'd mostly be using the app to screw with friends (or my girlfriend who "absolutely HAS to take this call" that's completely unimportant and ruins our dates). I would make it easy to turn on and easy to turn off.
On the other hand, an emergency SOS application to ICE (In Case of Emergency) friends would be an easy application to write. In fact, in India, they have developed a cell-phone jammer that will intercept all emergency calls and texts (outgoing and incoming) and allow them to go through.
I just think of the idea as a fun mod to develop. Is there any professional mobile programmers out there that support my cause?
i actually own a cell phone jammer, and trust me, the thing sucks more power then a phone could deliver and it can get insanely hot. I do see both sides of this argument though. It is really funny to screw with your friends. Especially when you walk into an at&t store and laugh at all the iphones saying "no service" , and then all the employees stare at you because your the only one in there and all their phones say no service. But when i bought mine, i did take into consideration that people do need to be reached by phone for emergencies. that's why when i use mine, i only use it when i'm in someones house and know that there is nothing that could go wrong emergency wise, or if I'm in public, i will only use it if someone is on there phone talking pointlessly or loudly. BUT, i only leave it on until there phone call is disconnected and then shut it off. I also have to agree with Toleraen, your phone isn't going to be able push out and transmit that much noise.
There are already such devices in existance. They are illegal in the US. One of the schools around here wanted to impliment one to keep students from using cell phones on the premisis. The FCC said no way, so they just check cells at the door now, along with other highly dangerous devices like toothbrushes and Q-Tips that can do bodily harm as well as distract from class room attention spans.
Emergency calls can still be made from land lines. If you are an on call ER physician, why are you at the movies while my mom is dying? It would seem that your skills would be much more valuable at an actual ER while you are on call.
Personally, I would rather go with the much more legal HREF gun which shoots a directional EMF pulse that just smokes the teenie bopper's bedazzled phone where it sits...
These jammers are not illegal in every country btw. Our Grand Opera Theater (free translation from greek lol) has that implemented in its rooms. So do many universities.
I personally i'm kinda on the against side, however it could be usefull in the above mentioned cases. Still I would like to strangle the person who "just happened to decide i should stop MY call on MY phone", but i have to admit it could be fun being on the other side of the situation

"on call" means they can call you if needed, it's not the same thing as being on duty. Medical facilities often have a staff capable of handling normal volume as well as x# of people on call in case volume rises above normal.
I've worked in a few "sensitive" areas in my life and there were what they called "bafflers" that would block cellphone transmissions. These were apparently well hidden away and not easy to know what they even were but yup, within the radius of where I was, no cellphone unless you had a 'special' cellphone that could work within a certain (read monitored) bandwidth of cell ranges.

You know how when you're on a long phone call the phone/battery start to heat up? That's you transmitting on a single channel. There are several hundred channels in that frequency range that you'd need to transmit, at a strength greater than the cell tower.
I don't think it's a matter of the software being capable (although you'd have to rebuild the radio firmware I would imagine), it's a matter of the hardware being capable. Discharging the battery that fast would be extremely dangerous and likely result in failure and/or burnination.
I think this poor guys request is gettin a bit blown out of proportion. No harm was intended, just a fun little prank. I understand an extreme case could happen where "your mother" would be in dire need of medical assistance and that ends up killing them. But jeeze, I'm pretty sure all the guy is trying to do is have a little fun with his friends. Funny idea but yea, might not be a very smart thing to do...

Here's an exercise to test this hypothesis: phone someone whose exact location you don't know using a landline. Did it work? If so, wait about 10 hours and try again. My prediction is that, unless that person remains next to a wired phone at all times, sooner or later this will fail. Are they going to let me drag a landline phone (with a REALLY long cord) into the movie theater with me?

If you are an on call ER physician, why are you at the movies while my mom is dying? It would seem that your skills would be much more valuable at an actual ER while you are on call.

1) How am I supposed to know ahead of time when your mom is planning to die?
2) I'm a specialist. There are two in my specialty in our area. That means I either live in the ER all the time or go about my life and live with interruptions.
Do you actually believe doctors sit around waiting 24/7 for people to show up? To clarify, Emergency Department physicians aren't typically ever on-call at all. They work scheduled shifts and are usually occupied the entire time. In large tertiary ER's, some specialists (orthopedics, general surgery, psychiatry, pediatrics, e.g.) may be scheduled for shifts. Most specialties don't have enough people to waste them sitting around in the ER, so they're on-call. You're not going to find a neurosurgeon, dermatologist, ophthalmologist, endocrinologist, etc. twiddling her thumbs in the break room. Many specialists cover several ER's in an area. At which one should they hang out if they were to decide to do Sudoku while waiting for something to happen?
If I were in an area with 29 others in my field with whom I could rotate call, I'd certainly hang around the house and not go to movies or whatever. That's not the case, and I'm on the other end of the beeper a great deal of the time. Since I'm on-call for a week at a time, waiting until tomorrow is not the simple solution it might seem. I have a family and a life to live. Most of my sleeping, eating, grocery shopping, and movie-watching gets done on-call. (In case you're curious, no I don't get paid in any way for being on-call but am legally required to be. It's rare that I get paid anything when I race to the ER and spend my kid's birthday tending to someone.)
Hey, you asked. Did you really not get the point that there are legitimate reasons why blocking cellular signals, even in movie theaters and restaurants, is a bad idea? I used what's called "an example" to illustrate a point about unintended consequences. In this particular case, I used a real-life example from my own experience. It shouldn't be that difficult to imagine a fairly different example that makes the same point.
If you want to pick nits, we can do that all day. I still contend that blocking cellular signals, especially if this is unknown to people in that area, is a really terrible idea.

I agree in both aspects. One inspiration is the annoyance with my girlfriend's cell phone etiquette. She has a friend that calls her all the time. While were hanging out, on dates, etc... and my girlfriend always picks up and they chat chat chat... annoying. Another reason is the experience. I'm a software student at a tech school and the learning gained from it would be amazing (which, btw is the reason I haven't replied in a few days... sorry, finals week).
Agreeing with a few others, the phone does not seem to be capable of doing this safely, and for very long. Even if it were a quick flip-on, close-down process, it would be very hard to write as a mod within windows. I would have to gain control of the radio from Windows, and find the drivers and commands to send signals out to the radio to broadcast, which would not be that powerful, maybe not even powerful enough to even cut an entire signal... maybe drag down or make difficult. If not possible to make within windows, it would have to be an OS or bootable environment (meaning, most likely, it would be changed to only have that function, no Windows) :-(
I've seen various projects of hardware/software students making these devices, such as the Wave Bubble project (google it, it's cool).
OK, another question. Has anyone worked with a cheap jammer that works on both US frequencies or has designed hardware to do it? Is there a place where someone could point me to solder and make an easy and powerful jammer (for information purposes, of course)?

Then you must be a freshmen, otherwise if you'd actually taken any electrical engineering classes at all you'd realize the phone cannot function in this way. How do you think it is possible for the transmitter, which is filtered to transmit at a very narrow frequency band so it won't interfere with all the other calls going on in the adjoining channels, can be made to transmit simultaneously across a frequency spectrum of 210 Mhz!?!? There are so many physical impossibilities to what you're wanting to do that it's pointless to even address them all.
I'll just say that you're trying to do is synonymous to taking a single garden hose and its little stream of water, and modifying it to somehow make rain all over a whole town, just because it would be fun to do.

On my first post i said that i bought a jammer. http://www.dealextreme.com/details.dx/sku.4355 this is the one that i bought and it's at half the price of what i paid, $26 for a cellphone jammer that operates on both GSM and CDMA frequencies is insane, they usually go for at least $200 for 1 frequency. it does fell kind of fragile, but i've had mine for over a year now and it still works great, range is good, and battery life is about 5 hours long. the only downside is it can get really hot if its on for about an hour. and you will click the button on accident when its in your pants, so you will know if its on by you having no service, or if your pants are a blaze. Comes with a wall charger and car charger. I like to jam peoples cell phones when there talking on the phone in there car, it's to funny and they shouldn't be doing it anyways.
i would be happy if one of you genuises would fix wm6.5 so that i dont have to reboot 45 times a day because of it getting so slow i cant even use it.

Horray!!! More radiation for us to bake in
So I take it the speed tests from flashing my new modem are going to be less-than-truthful at the moment.
I haven't noticed any difference in GPS performance
This happens more often than you know. It must be a slow news day today.
Ask someone that's Ham radio operator and they'll say the same. Sometimes solar activity makes radio waves go nearer or farther than normal. Sometimes it heavily attenuates radio signals. Or, maybe that's the end of the world solar flare that toasts everything on the planet like in the movie 2012.
LOL... But actually that was the movie "Knowing" wasn't it?

Yes it was the movie "Knowing".
I don't know, GPS might not be affected but this could happen...

LOL @ the guy doing the seal/walrus XD.
And, of course, absolutely nothing deleterious happened whatsoever in North America. These predictions are ridiculous, yet they keep making them every solar flare above an M5.
Source: Korea Samsung Headquarters clerk (from my country) sharing with his friend.
Reporting:
- Several High positioned personal resignations.
- The Firm stands strong and united, instead of despairing over the situation.
- Samsung's Engineers are working overtime over a new technology that will revolutionize the smartphone market. Priorly, this technology was supposed to be targeted for the following years. But after the Note 7 disaster, they decided to push it for the next Smartphone release.
----------
Opinion: Sounds legit. Just wanted to share the news. Nothing official of course.
I guess these "high positioned personnel" are the ones who pushed for batteries to be made by Samsung SDI. What makes it even more disappointing is, the replacement units are still SDI batteries. While we've heard nothing from the China region units with ATL batteries.
Samsung should shut their factory down and just stick with the winning formula.

Bad idea to start pushing for quick new technology. Look at the disaster the Note 7 was because it was rushed.

Agreed.
Instead they should solidify their present technology like avoiding explosions...

How do you know this? You don't. We don't know the cause yet.
Well! Tell them to fu** ing explain to us what was it they messed up so bad to infringe our personal property, safety and make us a ton of expences we will never get back!! Tell them they should be convincingnus they are not incompetent to make electronisc anymore in the first place!!
Its not the batteries that are causing the exploding. Its the tweaking of the software that controls the processor to run fast charging. Samsung tried to get a faster charge than all previous devices and screwed the pooch on the software. They can probably issue a software/firmware update but people will not be happy and it may not be a permanent fix.
I have turned fast charging off via the cable and wireless. I have zero over heating problems, zero lag issues, phone is acting like a phone. the real catch is concealing it when traveling on a plane etc.... That is the hard part. I will probably turn my Note 3 into my travel device for music and games and such. Like a glorified Android iPod touch. Ill just turn disable to mobile data and phone stuff, hide the sim card removed icon.
A lot of work still. Damnit Samsung.....
My note 7's (both the original and the replacement) have worked basically perfectly. They don't overheat, don't lag, really not a single problem. The Note 7 is by far the best overall smartphone made to date. Best display, best display to overall size ratio, best camera, waterproof, etc. Only two issues I would say are the edge display which makes a tempered screen protector impossible and a so-so external speaker. And of course the kicker - the non-removable battery. Had they just made it with a removable battery this issue would have not been a phone-killer. It is sad that the best phone ever made to date is killed off like this. And we still have no definitive answer to what is the problem? Seems incomprehensible.

That sounds like speculation. These devices have been melting without being charged. We don't even know if Samsung knows what the actual problem is. Hopefully it all comes out so we get some reassurance about their next phones.
I read a lil bit ago that they didn't know what the actual problem was which is why they decided to kill it. They had over 100 people testing them round the clock and could not duplicate the issue of causing one to smoke/catch fire... of course though they were an anonymous
person close to the situation.

Look, I get it, I want to keep my phone as well, and I am not sure what I will do. But to fly with it, while you base the rest on rumors, is plain irresponsible. What you do at home is your business, but getting on a plane with several hundred passengers and a possibly defective phone isn't (there's literally no way for you to tell whether your phone is safe or not). Samsung did after all improve the replacements as they are reportedly catching fire without being charged.
