Phone #1:

random reboots, Super short battery life, would not stay connected to wifi reliably, poor batter life and it died in less than 24 hours and could not be turned on again. The battery meter just kept dropping even though it was plugged in and the charger and cable were good.

Phone #2:

WIFI: While NOT holding the Sensation in my hnad….The signal is always about 10dBm below my laptop and iPhone when in the same location. Installing a wifi finder reveals that access points are present one moment and gone the next unless they have the strongest signal. The iPhone and the PC see 10+ access points and the Sensation can only see two of the three in my house. If you install a signal analyzer it reveals that the Sensation shows the signal varying wildly while the PC and iPhone show a steady signal.

BLUETOOTH: While playing audio the signal fades and the music skips unless the Sensation is within 2 feet of my Motorol S9 headset. if I put it in a sweathshirt pocket I get skips. If I put the sensation on my pants pocket the audio cuts out 50% of the time.

Other issues: short battery life, stalls, browser hangs, phone search results put web results at the top of the list and contacts and music at the bottom of the list off of the screen making the user think that it is not searching contacts (what happened to ranking the results and displaying the highest ranked and closest matched?), song somtimes changes when unlocking phone, VM notification still displayed when there are no messages, hard to sync music automatically and most third party sync software doesn’t sync play counts or ratings, bluethooth integration with built in music player is poor, you have to tell the music player to use bluetooth each time… even if the bluetooth headset isn’t already connected. Compared to the iPhone, the navigation is inconsistent. Sometimes you navigate back with the back button, sometimes it’s in the software.

I think I’ll go back to the iPhone, it is not as flexible as the Android OS, but it executes it’s core functions flawlessy. The Android OS, or maybe the Sense overlay doesn’t seem ready for prime time.

i think it can help you very  much

I am a long-term Blackberry user that uses his phone mostly for
business but also for managing personal accounts. For several years, I
have used Blackberry to handle my messaging demands including two (2)
exchange accounts and four (4) personal accounts. I had been waiting to
move to phone that could smartly handle these needs, and I have found
it with the HTC Sensation. I bought this phone early and have been
using it since 6/10/2011.

Email / Exchange Capabilities

HTC has customized the email application, and it is smooth,
elegant, and fast. I had no problems configuring my Exchange, MSFT
Live, and various POP accounts with the phone. The Sensation quickly
synced all my accounts with ease. The Exchange integration is
exceptional: you get push email, push calendar, and push contacts
integration.

HTC also features a flexible presentation model where it unifies
your emails into a single box and color codes the email by account
received. You can also use a dropdown menu and select to view a single
mailbox at a time. This mail implementation is better than anything
offer with the BB, and more robust than the messaging application on
the iPhone.

When you receive an email, you will get a notification through
Android’s notification menu AND and LED indicator will flash. BB’s
universal implementation of a notification light is a simple yet
necessary function for me, and I am glad that HTC has decided to
include a notification light. It is not as bright as the one found in
my BB, but it does the job.

I don’t use gmail, but interestingly, that is managed by a separate Google provided email program.

Contacts Integration

HTC has again included its Contact management application instead
of the Android stock, and it is an elegant solution. One of the
benefits of their application is that it will link duplicate entries
into a unified contact account. So, if you have someone listed in your
Exchange, POP, social networking address book, it will allow you to
link these into a single contact entry to simplify your contact list.
It’s a great feature and helps you organize everything.

Push Calendar

No issues with it. I believe that the included application looks great and has no problems syncing with Exchange.

Build

This phone has exceptional build quality. It is made of aluminum
and plastic and feels great in your hands. Not only the phone
comfortable to hold, but it feels heavy. I like a heavy phone: it
speaks to the quality of the build materials and does not feel like it
will break apart with use.

The main navigation buttons are virtual, haptic buttons located at
the bottom of the phone. The one issue with these virtual buttons, is
that sometimes I accidentally trigger the “back” button when I intend
to depress the space key. This is not a major issue, and one that with
practice you begin to avoid.

The power/wake up button is on the top of the phone. It is
responsive and has proper travel and response. The only other physical
buttons are the volume rocker on the left of the phone. The one thing I
miss is a dedicated physical camera button. Instead, you have to
trigger the application through the menu system and then use the
virtual shutter button on the screen. Again, I wish there was a
physical camera button, but it’s not a deal killer.

Phone Audio

Phone calls are loud and crisp, and the large ear grill allows you
to hear calls very well. Callers commented that they had no problems
hearing me as well. When this phone makes a call through Wifi, the call
quality increases even more and the voice quality becomes even more
outstanding.

The speaker is on the bottom of the phone; so, if you turn the
phone over, the volume picks up. My Blackberry has the advantage of
having the speaker on the top of the phone; so, this phone flip is not
necessary.

Keyboard

The other important departure from the Blackberry was the physical
keyboard. I was very skeptical and had not been impressed by other
Android based keyboard’s such as the one on the Galaxy S. HTC has
implemented two custom input methods. Its keyboard substitute works
very well and functions like the excellent keyboards found in Windows 7
Phone phones. The large screen also minimizes errors. HTC has also
implemented its own version of a Swipe keyboard. It works fine, but I
prefer the HTC keyboard. Coming from the Blackberry physical keyboard,
I am actually faster with the HTC virtual keyboard, which was my
biggest surprise when using this phone!

Android Wifi Calling

I relied on Blackberry and T-Mobile’s UMA implementation. This
allowed me to get perfect service from my home, receive signals at
work, and make calls when traveling internationally. T-Mobile has
integrated its version of UMA calling the HTC Sensation. It works just
as well at the Blackberry’s UMA implementation. Once you active the
feature, it signs-in seamlessly with WiFi networks without further
intervention. This is such a huge feature that T-Mobile should
aggressively advertise, since it allows you to place calls in locations
where no phone can receive cellular signals.

Conclusion

In short, buy this phone. It’s fast, well-built and packed with a
great package of software features that make it perfect for business
and pleasure.

*** P.S. IF you will buy this HTC Sensation 4G I suggest at: http://www.amazon.com/gp/product/B0053Z8XCO/ref=as_li_ss_tl?ie=UTF8&tag=slashgear.com-20&linkCode=as2&camp=217145&creative=399373&creativeASIN=B0053Z8XCO

If someone goes to the effort of compiling the latest version of Android into a ROM that works on your phone, and your phone is rooted and has an unlocked bootloader, you can install the latest version of android on your phone.
