This was my first touch screen phone, known as either the HTC Diamond, or HTC Touch Diamond depending on the region it was sold in. Its model number is P3700. This one's had a hard life and is now proudly showing it's battle scars
When new it had Windows Mobile 6.1 Professional installed as its operating system, with TouchFLO 3D as the user interface. Hardware wise it had a 528MHz CPU and 192MB of RAM. 256MB of flash memory for the OS and an additional 4GB of flash memory for the user's data. There was no card slot for additional storage.
The resistive screen had a resolution of 480x640 which looked nice, and it had two cameras, a 3.2 megapixel for the rear, and a VGA CMOS camera for the front.
Connectivity includes a 3G radio, Bluetooth, Wifi, A-GPS, and mini USB through the propriety ExtUSB connector
The battery was a 900MAh although there was a larger capacity battery and new rear cover available
Compared to modern smart phones it's tiny, although it does look good
While the screen was a resistive affair, however it could tell the difference between a stylus and a finger, when using the stylus text would be selected, but using a finger in the same location would scroll the screen instead
The ExtUSB connector allowed a mini USB plug to be inserted for charging and data transfer, and also stereo headphones, but not at the same time unless you bought the splitter
Around the edges are the volume and power buttons, the ExtUSB connector, and the texts HTC INNOVATION and 4GB INTERNAL STORAGE
Under the screen is a capacitive area which includes a home, back, phone, and hangup buttons, and a central select button. These were backlit with a white glow. The button presses were registered by the location of the finger on the panel when it was clicked. You could also rotate your finger around the central button to scroll through lists
The stylus pops out the bottom and turns on the screen, it's held in with a magnet. Popping it out can also open the notes app, but this can be turned off as it's annoying
Here's the back of the phone with the cover removed, the battery is a 3rd party battery as the original battery stopped holding charge. You can see the reset button hiding in the corner
Connecting a charger to the phone shows a breathing style animation from the LED's around the select button, these could also show notifications by a rotating effect, connecting a charger would also turn the phone on
However this phone is stuck in a boot loop, but it will boot to the tricolour screen used for flashing ROM's and hard resets etc.
As it was stuck in a boot loop I tried a hard reset to no avail
This is the phone next to a Huawei P Smart for a size comparison
I still have the box it came in, I think this would look good with a screen and a Raspberry Pi installed inside, what do you think..?
