Tech blog

This blog is for my future and past info and reviews on various tech stuff….

Watches, bands & rings	Phones / Phablets	Compact cameras	Reviews	Resolution and Noise
Batteries and usage	PC & Code	Various tech stuff	Math	Other stuff

Newer reviews can be expected to be ongoing projects, with minor additions or corrections.

Note: When I rate stuff, a 10/10 does not indicate perfect in an absolute academic sense, but as in (at least) as good as could be expected at the time, minor flaws allowed. For portable devices typically limited by the size and weight. Value for money also counts. An electronic device that got a high score in 2005, most likely would seem like pure trash ten years later….

2026-05-11. After using Discus for many years, and using an ad-blocker, I only recently noticed all its ads, so now switching to WpDiscuz.

• BlackBerry Priv AT&T Autoloaders, including old for debloating!

  If you want to reapply firmware to an AT&T priv that has been debloated, AND keep it debloated, you need a little trickery…

• More on Windows and scaling

  About a year ago I made a post on windows scaling

  

  So I tried to see if they have fixed stuff the past year – and NO it is actually worse now…

• C# Set volume example

  It took me quite some digging to find a clean way to set the standard default volume without external libs. So here the result.

  If you do not want the console output, remove the writeline, and change the project from Console to Windows App.

  I suggest using it as a Scheduled Task triggered by connect to user session and/or similar.

  It is composed of a couple of bits and pieces combined/reduced primarily from these three.

• BlackBerry Priv, 5¼days stamina, no tricks. Display on 50m/day

  The BB Priv has a pretty nice stamina, if it is not too infested with bloat (mine is debloated).

  Though some complains that a 3410 mAh battery is too small for a phablet with a 5.4″ QFHD display, it is enough for me.

  5¼ days on 96% battery

  

  This is with no trickery of radios off or similar. 4G, WiFi, NFC all turned on. GPS off though. ADD: BT off too.

• Phillips BDM4350UC. Mini review. An even greater monitor…

  This 42.51″ IPS has substantially better viewing angles used close than its 40″ VA predecessor, but poorer blacks, otherwise much the same.

Blog in English (well sort of, bare with me, non-native…), a few earlier than 2010 are just blunt copies of the source texts in Danish – Google translate helps here….

Collecting of old stuff started May 2015. Entries are generally attempted dated with original stamps, even if they are somewhat updated since, several reviews have been ongoing ‘projects’.
