I upgraded from a Vibrant.
Screen not as sexy
Speakerphone garbage in comparison
Speed is great
Sense 3.0 is way underbaked. Lots of stuff needs to be fixed or refined
Love the build materials, the build quality is OK
Front Facing Camera sucks
Rear camera is good except for autofocusing close ups
Volume rocker is too easy to activate
Battery life is much better than on my Vibrant
Audio quality thru headphones is so so, not enough volume
reception is OK but it does have the tendancy to camp out on weaker cell signals before switching to stronger ones.
WiFi reception is poor
GPS locks on quickly most of the time, a huge improvment
Upgraded from MyTouch 3g Slide(unrooted). The Sensation is Light-Years More advanced!
Going from single core 600mhz Qualcom, to a dual Core 1.2ghz Snapdragon Processor, twice the Storage, just to name a few, this phone is a Big Boy toy! the MTS felt like a toy! Very Plastic! This feels like an adult phone! It has it's issues but it is still new and they will be worked out as they were with the MTS!
I upgraded from Blackberry curve last week, so far these are my observations.
+ve for sensation
speed, screen, GPS, browser, camera
-ve for sensation
emails, (blackberry still rules in this aspect, setting up, delivery and notificatoin is much better)
battery life ( very poor)
it gets hot if i view video, play game for more than 10 minutes
speakerphone ( for both voice calls and music playback; it sucks )
i don't have any issue switching from physical keyboard to touchscreen keyboard of sensation. and after insatlling swiftkey, it is as good as physical keyboard.
Updated from a Samsung Vibrant. (PS- I will never purchase a Samsung Phone Again). This is by far, the best phone I've ever owned. Fast, Great GPS etc. All I can say is that everyone needs to remember that nothing is perfect. The Lock Ring issue is an occassional issue and the speaker could be way better, That being said..... This phone is awesome. A Ferrari compared to all the Junkers I've had in the past. Long live HTC. :-)
I came from a Motorola DEFY. Technically I came from the G2x but I only had it a week so it doesn't count imo.
Motorola DEFY HTC Sensation 4G Screen 3.7" TFT 480x854 4.3" Super LCD 960x540 Battery 1500 mAh 1520 mAh Processor 800 mhz single-core 1.2 ghz dual-core RAM 512MB 768MB Storage 2GB (1.2GB user) 4GB (1.1GB user) OS Version Android 2.2.1 Android 2.3.3
Sound on DEFY is MUCH louder and clearer than the Sensation.
DEFY is water resistant, dust proof and shock resistant. Not so sure about the Sensation. lol
DEFY has stronger reception.
Not the least bit sad about my upgrade to the Sensation, it is better in almost all ways (except for sound, obviously).
I also have a curve, have had a few.
I can tell you that the battery life and matter of the device getting warm when playing video are normal for a transistion from any BB to most any Android device. Android can run more processes at once, so it's going to use more battery, and intense processes such as video will make a device warm. It's not a real problem though, unless you ever have issues charging.
And yea, the e-mail thing. Speed and the best security (so good some governments try to ban it) are basically the only reason people still buy from RIM these days .
I'm coming from a Vibrant, and although I had my Vibrant just humming with it rooted and running a good ROM, this is still a much better phone. I'm so looking forward to having the boot loader unlocked. This phone has tones of potential, but is really being bogged down with blot ware. I’m guessing within a couple months we’ll have a real unlock that is not temporary and some really sweet ROMS that just make this thing screaming fast.
Since you already know about temp root, you should give the app Autostarts a try if you have not already tried it. With that along with Titanium Backup I keep the Sensation pretty tame. I use Autostarts to keep any apps I use from ever starting on their own. And with Titanium Backup I "freeze" any apps I don't use. (I could even uninstall system level bloat apps if I desired, but I just freeze them. The ones I want out of my way.) You have to be very careful when using Autostarts and Titanium Backup though.
With those, you can basically customize the stock ROM to your liking. Because things that are restricted from starting or frozen remain that way even when you lose root access.
I could be regarded as a smartphone jumkie...owned HD2/every iphone.galaxy S vibrant/s4/mytouch 3 and 4/nexus one and S/ LG G2x....lots of HD2's..btw greatest phone for rom and hacking...the Sensation is about as good as it gets...if you know your stuff, dopey things like volume and wif issues will make youchuckle...it's a great phone...about as good as it gets...if you want a phone that demands no more than switching it on, it hasn't been made yet...
