HTC Sensation 4G Review - A Sensational Smartphone

WiFi Hotspot

The Sensation includes HTC’s own WiFi hotspot software, and nothing much is changed between it and previous versions. It’s still limited to 5 users maximum, and you can view and manage each one’s connectivity. I don’t remember them being options before, but the Sensation also lets you change the WiFi channel and DHCP server settings in the advanced menu alongside the standard power timeout options. I tested the Sensation’s hotspot capabilities pretty extensively and found that things work out perfectly well. Thankfully there aren’t any bugs to speak of, which is more than I can say for the hotspot software on some other recent smartphones.

Speakerphone

Speakerphone on the Sensation isn’t quite as loud or as high quality as we’d like it to be. To be honest, this is probably the only really glaringly bad part of the whole device. I used the phone for navigation a lot while driving the 400 miles to and from California, and then on a trip or two to Phoenix, and the speakerphone volume just isn’t high enough. Listening to music at maximum, it isn’t adequate. For calls, it’s disappointingly quiet and grainy. I’m not sure what happened here or if something needed to go with the phone for it to fit into this form factor, but clearly the speakerphone took a back seat during testing and design, or there’s something flat out wrong.

There’s a grille on the plastic back of the Sensation, then another metal grille. There is a small rubbery ring around the thing as well, so it isn’t like sound is disappearing into a void between the metal case and the plastic back. It just isn’t loud enough. 

Voice Calls and Audio Codec

We’re still trying to create an even better way of characterizing and presenting voice quality for smartphones. Until then we’ve provided a recording of the Sensation calling the local ASOS weathe report station by connecting the headset jack to line in. The Senation’s headset audio quality and earpiece volume also are good. The Sensation, like most modern phones, also has ambient noise cancellation which I tested by calling a friend in a very loud environment. Background noise around me was hard to detect on his end. HTC is no doubt using the Fluence noise cancellation audio chain onboard MSM8260.

I listened to lots of Google Music on the Sensation using my pair of Shure SE535 earphones, and found things overall pretty good. The Sensation uses TI’s very low power TLV320AIC3254 stereo audio codec. 

Qualcomm's GPS

Last but not least in this section is GPS performance. The Senation uses Qualcomm’s Gen 8 GPS which supports standalone and assisted (A-GPS) mode. I tested and verified that I get a fix from cold start both with cellular connectivity and without WiFi or cellular connectivity. It works and it works well.

Note that airplane mode is on.

In addition, the GPS on the Sensation locks astoundingly quickly. It’s almost instantaneous, which is especially impressive after using the Droid Charge for weeks before, which often took either a few seconds or a full 30 to get a 3D fix.
