آره ۱۸ تا صفحه قبل و بخون همش خبر!!

منظورم خبر جدید بود نه خبر قدیم!!!!
بیشتر منظورم اینه که کی وارد بازار میشه و قیمت.
همچنین خبرهای جدیدی از نقات قوت و ضعف گوشی بود

جي اس ام آرنا هم مشكل آنتن دهي رو تست كرده و مثل اينكه مشكلش هم خيلي حاد هست:

Death grip strikes again, HTC Sensation falls victim when you hold it wrong [WE TEST]a

Death grip is a sensitive topic, but I’m afraid we’ll have to stir it again. The HTC Sensation barely entered our office and we’re already trying to strangle the (wireless) life out of it. The problem is two-fold – the Wi-Fi antenna and the cell antenna – they both get attenuated when you hold the phone in what you may call a natural way.

The two antennas are positioned on both ends of the phone – the cell antenna is at the bottom and the Wi-Fi antenna is at the top. Cover them with your cupped hands while holding the phone naturally in landscape position and you will see the signal degrade. But don’t just take our word for it, we have it shot on video.
Here’s what we found after several tests. The Wi-Fi antenna is very sensitive and it doesn’t take much to kill the signal. The cell antenna has a death grip issue but it only matters in specific situations.
These problems are caused by the decision to put the antennas on the outside – HTC should have learned from Apple’s mistake and not use the external panels of the phone where the user hands naturally rest as an antenna. In this case, the antenna is the built in the back panel. There are two sets of contacts that connect both antennas to their back cover ends, you can see them in the photo below. By the way, that also means that if you take the back cover off, you lose all wireless signal.

When you hold the phone up to your head, the problem is almost non-existent – no matter how much you cover the antenna, both sides can hear each other fine with only a sound artifact here or there. Even in areas of poor reception, things were really okay – you can’t kill a call that way.
But if the phone is held horizontally (say, to use the speakerphone), it becomes almost too easy to degrade the signal – touching the bottom area of the phone is enough for the call to start breaking up. If the reception gets any weaker, the call is dropped.
Oddly, while the person using the Sensation can hear the other party just fine all the way through, it’s the other caller that starts hearing artifacts and badly broken up speech. So, it’s a problem with transmitting the signal, not receiving it. Still, in most situations, the HTC Sensation should do fine.
As for the Wi-Fi reception, things are pretty bad, we guess. Put your hand on the top of the phone and Wi-Fi signal drops to zero. Very often the modem would crash and would switch the Wi-Fi on and off and only then you regain connectivity even if you were no longer touching to antenna.
Granted, holding the top of the phone is somewhat unnatural – but using it in landscape orientation to browse the net or watching a streaming video might give you some headache.
We recorded a video showing how both signals degrade as you touch the corresponding antenna. We couldn’t get the cell signal very low on video, but that’s because our office has good coverage.
For the Wi-Fi, we tried downloading a file from the Internet and measure the download speeds. Keep an eye on the blue line – it shows the download speed in Kbps. It drops to the bottom when you touch the top antenna. If you are lucky and the modem doesn’t crash, you might even get to finish your download.

حالا جالب اينجاست HTC هم مثل APPLE كلا منكر قضيه شده :

HTC does an Apple, denies Sensation death grip issues exist

HTC has obviously taken a leaf of the Apple book of PR and denied today that their Sensation flagship has the so-called "death grip" issues. There was no press-conference this time, but a company spokesman did go on record and denied there was anything wrong with their powerhouse of a smartphone.
Here's the exact quote as sent to Slashgear:
“Every phone experiences a slight variation in signal strength when the antenna is covered in its entirety by a palm and/or fingers. However, under normal circumstances this does not affect the performance of the phone.”
Now the first part is absolutely true - you can drop a few bars on just about any handset out there if you hold it in a specific way. Yet our dedicated test revealed that the Sensation can lose all of its Wi-Fi signal quite easily in what we wouldn't call abnormal usage - it's just how you’d hold it if you are web browsing in landscape mode, for example.
Mobile network signal also suffered if you put your hand in the wrong spot, thought it didn't seem to be as damaging there. Now, we are not saying this is a deal-breaker - the Sensation is still a pretty hot device with all that oomph under the hood, but it's still a quirk you should keep in mind if you are about to get it.
And we really don't think dismissing the problem as non-existent will do any good to HTC. There are plenty of early adopters out there who will confirm that they were unpleasantly surprised.
Update: HTC just responded to a question about our video posted by one of their customers on Facebook, claiming that "The HTC Sensation issue seems exaggerated in this video, which is why it is misleading.". We find this statement largely inaccurate, since as we mentioned this is the exact way you would hold the handset if you were web browsing in landscape mode, for instance.

Still we will be shooting another video of the problem later today,just to demonstrate the issue in the more natural landscape handhold. Expect it to appear in a few hours in our blog.

یعنی خود htc گوشی به این شاخی رو تست نکرده همینجوری داده بیرون که همچین مشکلی رو متوجه نشده ؟

[PersiAndroid]

نميدونم چرا اين اتفاقا ميوفته!
تازه يه كمپاني مثل اپل كه تمام تمركزش هم روي يك مدل گوشيه باز هم از اين اشتباهات مي كنه!
