does anyone here have one and if so, which brand do you use?
Are you talking about those things you stick on the phone to reduce radiation? Those things are a joke. Nothing you stick on your phone is going to reduce or block radiation to any significant degree. And if it did, it would also affect your phone reception. Remember, cell phone radiation goes right through buildings, trees, cars, etc. A little sticker isn't going to block it.
Those things are just like the stickers that are supposed to amplify your cell signal for better reception. They do nothing, and are just a waste of money. In fact, I wouldn't be surprised if they were the same product, just sold in a different package.
If you want to reduce your exposure, buy a phone with a low SAR, minimize your use, and keep the phone as far away from your body as is practical when not in use.
Just wanted to second that. The information posted is 100% correct.

That can't happen with me. I need my phone with me most of the time. Don't worry - You'll find me in a few years. I'll be the only person on earth glowing green
lol, thanks guys.
I just got worried bc i will be carrying around 2 tp2' now instead of one S) and on one, I will have data running constantly.
Get a bluetooth headseat and keep the phone just within range of it

yep... Bluetooth headset and keep it in your pocket... that way the radiation isn't going to your brain but to your crotch!
PHONE DO NOT WORK THIS WAY!
Mobile phones use non-ionizing microwave radiation and you will NOT get cancer from them.
I want to buy the HTC Desire Z but a few things that I read on the net are really freaking me out:
1) BATTERY LIFE: Some users say the battery lasts for less than a day, while others say they have no problem for 2 days. Now I have a ZTE Blade(which I plan to sell) that also has bad battery life, somewhat similar, so its kinda OK as long as its not really that bad.
I wont really have the Wifi turned on 24/7, coz I am a conservative user(although when I get the phone initially I'll check it out every 10 seconds... only for some days).
Can the battery life be fixed by using custom ROMs or Kernels or is it just the underpowered battery pack?
2)Keyboard Hinge: It seems that the screen falls loose when you turn the phone upside down. Some people complain of loose hinges .
I will be using the keyboard frequently.
3)LAG AND BUGS: Actually, its software related so it doesn't really matter I would probably flash a Custom ROM as soon as I get.
So should I buy this phone or not? Please tell me about the other problems in this phone...
If you say "NO", then please suggest an alternative in the same price segment!
Thanks a lot!

I've had my Desire Z since august last year.
Pros:
-great dev support with PLENTY of ROMs to choose from, you get choices between AOSP, GB Sense, GB MIUI, ICS Sense and ICS MIUI.
-good sound quality output through headphone jack
-great screen with nice viewing angles and colours.
-good battery life lasting 2 full days regularly for me under light to medium use.
-great keyboard which has a good feel to it.
-fantastic build quality, i've dropped my DZ a bit more than a handful of times and it barely has any scratches anywhere.
-the "z-hinge" is much more sturdy than it seems and it will definitely last the test of time.
-the phone is blazing fast with AOSP ROMs and can play pretty much every game right now.
-Call quality is really good when there is good reception (read below)
Cons:
-sometimes not-so fantastic performance when it comes to Sense ROMs.
-my keyboard is becoming unresponsive and requires very hard pushes to register the keys Q,W,E and more recently the space bar is having this issue too.
-i have had both wifi and cellular signal death grip issues that occur when the keyboard is out and my hands are wrapped around the device.
-With wifi, a full bar signal can drop down to half signal or less than half if you hold the device as i described.
-With cellular signal, i have very poor reception at my house where i'll get 3/4 bars at the most but a lot of the time, if i hold my phone for more than 30 seconds while the keyboard is out with my hands wrapped around it, i will end up completely losing reception. That said, this has been an issue with previous phones of mine anyway though.
-The device does get hot at times where it can make your hands sweaty but it never really gets burning hot.
-call quality is quite terrible for me at times at my house due to the bad reception that i have and the death grip issues seem to interrupt calls as well at times as i've had a drop outs during calls before.
I hope that helps a bit. Oh and about the tightness of the Z-hinge, i can hold my phone upside down with the keyboard open without it closing, it takes a little bit of practice but my hinge is quite tight and it's still as tight as it was when i bought my phone so as mentioned earlier, the hinge will definitely last the tests of time.
Overall, the pros outweigh the cons for me simply because of how much i love android, so i'd give the phone about an 8/10. If you can find it for like $250USD or less, i'd buy it if i were you, but otherwise, i would just wait for the next best qwerty slider.

Thank you for answering!
But there are a few new problems(Call reception, bad signal) that you have just enlightened me about. But should it really matter at a place with full network strength?
But seriously, the PROS seem tooo attractive! The number of ROMS is amazing.
I guess I might just go to an E-store and check out the DZ today!
Then I'll make up my mind.
Thanks again for your helpful post.

I bought my DZ a year and a half ago and i've never encountered major issues other than ROM depending ones.
I live in a french "big city" and never have signal troubles.
Sure he doesn't have incredible performances (mostly with Sense 3.x Roms) and if you want to use it while lying on your bed and holding it above you you will suffer of a loose hinge but if you can find it at a reasonable price, it's still a good deal and one of the best with an HW Keyboard.
Might be worthwhile to check out the official review thread in the General section.

If you live somewhere with good reception and you can get the desire z at a good price, then i'd say go for it . When i have good reception, calls sound pretty much perfect. It's just that my carrier somewhat sucks haha.

My carrier sucks too, but only outside the city, but I get full signal strength with my ZTE Blade in my house. Considering that the ZTE Blade has similar network issues, I think I don't mind the bad reception issue. Things are getting positive for this phone... I couldn't go to see it today, but I'll try tomorrow!

Yes, HW keyboard is important as I always face issues with my existing phone when it comes to using the on-screen keyboard. Well, I'll just grin and bear the loose hinge.
Thanks to everyone on this thread. I seem to like the phone now.I just need to see it in reality to make up my mind.
it's just the keyboard issue, other than that , the phone is awesome
Very quick fix if you feel the keyboard is loose. Check the thread on the spring fix. I did both mine and my girlfriends g2s in 20min. As for reception there are more radios to pick from then on any other device I've used so chances are at least one is good in your area and this may help with battery life too. Also I get about 20 hrs give or take with most roms and I'm a heavy user. My gf still has over 80% battery when she plugs in at night as a light user. Not to mention many after market batteries to pick from.
Did a lot of research before I bought us both g2s and I could not find a better option for us as the keyboard was the hw biggest need for us

The screen is meant to be loose, in that it allows you to flip the keyboard open and closed with almost no effort. I actually find it pretty tough to hold the phone in such a way, that it opens when upside down. Any contact with your fingers/hands on the "screen" portion of the phone will prevent it from opening accidentally. You actually have to be holding the back "half" of the phone without touching the front "half" in order for it to open while upside down. A few people have mentioned that the phone opens when they are using the phone and laying down. But I often use my Z while laying on the couch, and have never found this to be an issue. My opinion is that the hinge "issue" has been completely overblown, and don't let it negatively sway your opinion of the phone.
Battery life is obviously a very difficult thing to compare between users, as its very dependent on how you use your phone, and also reception. But with fairly moderate use, the Z will easily get you through the day, and then you charge overnight. With light usage, I can often get 2 days. On the other hand, when I'm hiking in the woods, in poor reception areas, I can kill the battery in 8 hours or less, without even using it. Forcing the phone to EDGE seems to help, as some of the battery drain seems to be from the phone constantly trying to connect to a dodgy 3G signal. Similarly, in less populated areas (but still in built up towns) I will sometimes get battery life much less than the usual 1-2 days I can get at my home and work locations. I guess the moral of the story, your mileage will certainly vary. But for average conditions, I'd say the Z has pretty good battery life for a smartphone.
All that said, the Z is a solid phone, and a great community here. But I'd be hard pressed to recommend buying one at this time. The phone is a year and a half old. The CPU and memory specs are really showing their age. And its unfortunate that flagship devices with hardware keyboards seem to be becoming an extinct species. I'd only consider this device if you really require a hardware keyboard, and can get a good price.

I guess if I buy the phone, I'll have better battery life as I have my cellular plan limited to 2G so that is going to make a big difference. Anyways its not like my existing phone(ZTE Blade) has great battery life and reception, so I'm used to this.
And ay the community here is AMAZING, the number of ROMs and Radios is superb! I am no fan of OC'ing so CPU speed doesn't matter. HW keyboard is soo tempting.
Thanks a lot for all your responses... I'll search for the spring fix for the keyboard...

Actually have to say that this statement is a bit backward. If you were into overclocking, that would make up a bit for the lower "stock" CPU clock speed of 800 MHz. As it is, the CPU on the Z is good enough for most tasks. But newer CPUs are pushing 1.5 GHz, and multi cores, and you can really tell the difference. My tablet is a HTC Flyer, with a 1.5 GHz CPU, and it just, well . . . flies. So much more smoother interface experience (even with Sense), smooth video playback (Rockplayer), and this is only with single core (most phones are now coming dual core, and quad core coming soon). Plus 1 GB of RAM means much less dropping of apps from memory. My Flyer acts like I wish my Z would.
Again, don't get me wrong. The Z is solid, and will still have plenty of life left, if you really need the keyboard. But its nowhere near cutting edge, and for me its time to move on. I'll likely be picking up the One X when its released.

I mostly agree with this post and his previous one.
I'm also considering buying an HTC One X.
It seems so great : Tegra3 1.5Ghz QuadCore - 1GB RAM - Screen resolution : 1280*720px, Internal Memory 32GB, Front Camera, NFC, Native ICS + Sense 4 in its full version
Compared to our DZ, that's just like WOW !!
But no hardware keyboard anymore and no real HDMI connection (you need a special cable).... for a 600€ phone.... that really pisses me off.
@ the OP, i think you should wait a couple of months until some new phones come out so that you have more choice. I'm personally HIGHLY considering getting a One X or One S if i can find the money for it as the keyboard on my phone is driving me nuts xD.

I don't want to contradict you, but I never overclocked my existing phone which is only 600MHz and I was pretty satisfied because I used custom ROMs. The only Overclocking that I did was to OC the GPU. But the stock 800MHz on DZ is good with custom ROMs as I saw on youtube...
Well I'm still a teen so the One X is a tad too expensive. I txt, so HW keyboard is a necessity. I have an iPod touch 4 for 1GHz . I use that for Gaming, media, etc(you obviously know)...
Yes the market is full of Dual and Quad core phones and tabs out there but I might just venture out to that segment when I'm actually looking for a good quality phone to use long-term when I'm older(Coz my parents don't think I'd handle those kinda expensive Gizmos)

After reviewing the phone in a store I was pretty impressed and there really wasn't anything wrong with the keyboard(firm enough) on that piece so I think I'll just have to have my fingers crossed to get a piece that has a stiff keyboard.
I need to buy a phone quick as my ZTE Blade's value is going down and I don't want to spend too much on upgrading. The only competitor IMHO to the DZ is Xperia Pro. So I think I'd either buy the DZ or the Xperia Pro...
You're talking about the mini pro? Or is there another version of it? The dz will probably have a larger community since that device wasn't advertised too much. It's still a great device though, a friend of mine's got it and I had the chance to play around with it.
The phone's hardware, as redpoint73 stated, is indeed starting to age. It can last for a bit more than a year, if you don't mind the slower hardware. So, it might just be worth it if you upgrade every 1,5-2 years.

I bought my ZTE Blade just 5 months back, so you know that's pretty short... I will obviously upgrade in the future if there is another phone that I fall in love with

Its largely a matter of personal preference and needs, so feel free to disagree! Its you buying the phone, after all. But for me, its really quite evident when comparing the Z to more modern phones, the difference in CPU. Lightweight ROMs help, but its really just a Band-Aid when the CPU is falling this far behind. But if you're on a budget, and can get a good deal on a Z, its still a solid phone.
Slightly off topic, but speaking of CPUs on newer phones, have you guys seen the recently posted benchmarks on the US (AT&T) version of the One X (actually One XL)? Dammmnnnn, this thing embarrasses every phone currently on the market, including the Galaxy Nexus. Much less an older phone like the Z:

I think that we don't care about the slight difference between the 2 processor as you can OC your DZ from 800Mhz to 1.8Ghz without problems (i know u can even go higher but i've never tried). Even if you're not fond of OCing, that's still a possibility.
Screen resolution doesn't seem relevant to me neither. 480*800 VS 480*854.....
On the other hand, the community should be a major argument as it's the one thing that allows our DZ not to be totally outdated.

Um, almost perfect, actually. And more better than many native English speakers on XDA. ;-)
grrrrr ..... it has 0.91 W/kg -> that´s quite high - it grills your brain...
speakerphone ftw
That`s if you have a really poor signal, as the phone has to transmit a more powerful signal, so the more bars the better for you, or use a corded headset for hands-free.

it's a lot better than Motorola and apple handsets. The only company consistently putting out low SAR ratings is Samsung. I have heard the SAR ratings given are suspect anyway, that continual radiation may be sustained higher than average even if the max SAR is lower than other handsets...
ie. (not REAL figures)
samsung max sar= .63 sustained sar= .60
HTC max sar= .91 sustained sar= .55
now I am no expert but I remember hearing something along these lines a little while ago.
I was dead set for getting HOX next month, but it's one bad thing after another.
Problems with screen flexing, inconsistency of screen quality (some have yellowish hue, some are nicely white), screen flickering, now high SAR value...
I must admit I'm rethinking my decision a bit.
I was searching for SAR value for HOX a few days ago and couldn't find the info. It's not a deal breaker for me, but it's just another item on the "against" list.
Just have to keep swapping the phone from ear to ear, so instead of one side of you brain getting 100% , each side will only get 50% and that has to be better.

Of all the things likely to kill me a cell phone is probably the least likely. I'm sure recreational drug use when I was younger did far more to fry my brain than anything HTC can concoct. Can you imagine what the radiation levels must have been like in early cell phones before we developed ways of tracking it?

Of all the things likely to kill me a cell phone is probably the least likely. I'm sure recreational drug use when I was younger did far more to fry my brain than anything HTC can concoct. Can you imagine what the radiation levels must have been like in early cell phones before we developed ways of tracking it?
You should get the SGS3. I'm sure it will be perfect and issue free just like the GN was when it launched.

What's up with the attitude? It's just a phone. And it Does have a lot of issues.
em....nice 720p screen or brain cancer....tough choice

Maybe it will, maybe it won't. I would still take HOX over plasticky Samsung, I just hope they would sort the issues.
As for SAR value, it's not dramatically high. Lower radiation would be nice, but I can live with it.

He has a point. Why is this thread even here? You're NOT going to get cancer from your phone. It wont happen. It wont kill your brain cells or lower your IQ either (not from radiowaves or anything anyway. It might lower your IQ if you sit there on facebook all day though ).
Also, what issues?
So far, the video camera is a bit disappointing and games are a little laggy (both of which can be fixed with software updates). That's it. No phone has ever been released perfect. This is easily the most stable-upon-release handset I've ever owned.

I am not a SAR freak like one of my friends who always uses only wired headset (not even bluetooth), but....you never know about brain cancer. its not something that comes up after 1 year of phone use. Who knows what happens in 20-30 years.......
few days ago in news some lab did a LONG study on dental x-rays and said people get brain cancer because of them and should avoid at all cost. People have been doing dental x-rays for ages and still think its safe.

There's a MASSIVE difference between a mobile phone and an X-Ray.
Even the National Cancer Institute says there's no known link between mobile phone's and cancer.
http://www.cancer.gov/cancertopics/factsheet/Risk/cellphones[/url]
"...to date there is no evidence from studies of cells, animals, or humans that radiofrequency energy can cause cancer."
Even if there IS a link, and mobile phones CAN cause cancer after 30 years or so, there are so many other things you do day to day that are much worse for your health and are much more likely to kill you.
The idea is to create a very low cost app and sensor to monitor the cadence of a bicycle. Since most of app can find the speed through GPS, I need one that count how many RPM I'm doing.
1. I don't know how to program android app or even which language I should use
2. The idea consists on adapting one magnet on the crank and the other on the bike frame near to the crank course
3. When the magnet on the crank goes through the other one on the bike frame it should create a small current
4. This magnet would be wired to the android based cellphone (perhaps a Galaxy Nexus) on the audio port
5. The small current should generate a sound
6. This sound should be intepreted as one full cycle
7. The software must count and store how many cycles per minute I'm doing
How could one do this?
distance / circumference = rotations
It sounds like you already have distance traveled from the GPS record.
If you can measure your tires, πd (or 2πr) will give you the circumference, and distance/circumference will give you number of rotations, no additional hardware required.

As I understand marcoskp, he want to monitor cadence ( rate per minute of crank not wheel).
In this case you should have information of current transfer also if you want to use speed from GPS to calculate.
But you can have situation when crank is stable and you are still moving.
So external sensor is necessary.
Using audio port is very good and easy solution, but cause of wireing, have you consider BT sensor?
It should work same but instead connecting it to audio port you create switchable transistor and count full circles (simple counter) as a rising slope. And those information will be sent via Bluetooth (counter value).
It will be only little more expensive ( BT module here is only one with real cost, and it's quite cheap ) but much easier to mount.
Thanks saffron82. More than that, bikes works with differents gear ratio. Some are fixed, but today people uses 21 to 30 speeds (or 20 if you are using sram's 2x10). So cadence may change a lot if you are using a bigger or smaller ratio. The idea behind audio port is also to consume less energy. But I may be wrong. Perhaps bt consumes less energy.

I have been looking into ways to increase signal and have found to promising settings one is antenna diversity as i find that transmit power is the limiting factor especially on b41 as my rsrp is better then iPhone 6 plus and note 4 from what i have found using diversity can reduce tx power 5 to 10 db as the secondary absorbs radiated signal and it coincidentally had been shown b41 is weakest and also that is the band that has much better rsrp than my other phones fcc limits to 23 db which is hit while rsrp is close to 100 which is very usable
Also i found a setting that reads sar sensor and had settings 0 through 8 we default on 0 Samsung is known for having very low sar output and increasing frequency usually increases tx output and once again coincidentally iPhone 6 plus was measured 31 db on band 41 extremely higher than any other phone and most hot spots and also is 1.59 on sar output once again higher than any other phone if anyone had any input would be greatly appreciated
longest. sentence. ever... Please use the key on your keyboard two spaces over from the "M" key.
Now as for your findings, certainly interesting. What are the settings available for antenna diversity? Are you able to choose between switched and combined?
Lastly, where did you find the setting for SAR configuration?
Their is both,primary, secondary, and diversity
Settings for sar is
Test mode
Ue setting and info
Settings
System
You have the option to disable the sar limiting.
I have searched high and low and their really seems to be no information on this however i do recall on my Nokia 3390 their was a code that was able to increase tx power i do know that the modem has to have different power levels if they are set in some low level way i don't know but different phones have different antenna gains so would have to have different power levels especially since mdm 9635 is used in broadband cards/hot spots as well which are allowed higher tx power
Sar back off is real their are articles about it on ipad
I have no idea whats going on in this thread.
It is referring to a sensor in our phones that when you are holding it in hand or get close enough lowers broadcast power by up to 25 percent to reduce radiation from phone

Not at all quite the opposite i worrying about trying to disable it to increase network performance
Well further investigation i found that qpst can access calibration of radio wondering if can increase transmit power
Ive searched all over, how are you getting into the settings to make these changes? or is this just theoretical?
None of the dialer codes get into the menus I think youre suggesting work any more, and I cant find any way to unlock them...
Im scared and confused
I'd be nice to get than one bar for a change. Way too often does my signal go kaput.
I disabled sar backoff in the secret menu, would this make radiation dangerous when using phone to make calls near ear/head? Also, what is best setting for the sar state from 0 to 8, and do those values matter if sar backoff is disabled?
Where is this setting?
I think you just have to keep backing it down until you reach a setting where your ear glows, then go back up one
Also; if you believe the numerous studies stating that non-ionizing radiation isnt harmful, then all settings are safe.
go to phones settings menu - activate this device - more->PST - TestMode Menu

I only did a little testing but I didn't see a difference between 0 and 8
Try testing the sar backoff flag setting too to see if it makes a difference

Dialer codes are only for carrier and manufacturer menu settings regarding to activation/device stats.
The things the OP is referring to is a level deeper, something you can't modify from a menu. It involves connecting the phone to the computer and changing values in codes pre-set for the phone's processor and sensors.
QPST is a Qualcomm tool. This stuff all delves into a different world than most deal with here at XDA, because most of the time if you are using QPST you are trying to flash a new carrier on your device, manually update or add a PRL that isnt "approved" by the carrier, or reprogram/ Clone/ fake/ spoof/ etc which gets into an even deeper world that is against the rules here, because its a slippery slope leading to illegal stuff.
So thats your answer in a nutshell. You wont find alot here about that stuff for the reasons above.
I wonder how much extra radiation is emitted with sar sensor disabled.
