WP7 Device Tests

No I didn't got lucky to have a dev device of my own. Last Wednesday I attended the WP7 Lab event in Milano and everyone wanted a dev device. We even tried to bribe Lorenzo to "forget" some devices in the bar, but as there was only 3 devices available and he had the same event the next day in Rome we didn't got lucky. Anyway I've spent some quality time meeting new people and testing the Samsung and LG dev. phones.

The first project that I've tested was the SqliteClient. Could be my impression, but there is a big difference between how an application looks&feels on the device and on the emulator (it looks a lot better on the device). On the speed part I did some tests on insert (the select/delete work almost identically) and here are some results:

Inserting 2200 Rows with transaction:
Emulator: 0.622 sec
L.G.: 3.35 sec
SAMSUNG: 3.244 sec

Inserting 600 Rows without transaction
Emulator: 7.067 sec
L.G.: 29.054 sec
SAMSUNG: 21.676 sec

On the beta release the device it's 4-5 times slower than the emulator. The Samsung it's faster as it has the storage on a microSd compared to the LG that has it on internal flash.

The other project that I've tested was the barcode reader. On both devices the test samples worked the same as on the emulator. When it comes to the integrated camera this is where the things get a little complicated. The camera app is one of those apps that the hardware manufacture will customize. None of the drivers had a macro function. The Samsung device had no settings to set, and the focus was pretty bad. The LG had the settings menu implemented and a better focus. Without the macro function it was hard to take a "clean" picture of a barcode but when the image was good the library works really fast and precise. I expect a lot on the camera part from HTC. I have to wait October and see.

One thing that got me thinking is when I've asked if Nokia is preparing a WP7 device they didn't say yes, but didn't say no also. It would be a nice achievement for both companies because Nokia does great hardware, but I've never liked Symbian and looking at the market shares they could take WP7 into consideration.
