I was planning to buy a blackberry z30 but stopped due to these:
-pathetic screen, not even gorilla glass. nowadays there are similar priced phones with unbreakable screens like z1 compact . even moto g is gorilla glass 3.
-after 10 wrong password tries, the phone wipes clean, nothing you can do about it. no setting to change it.
-its not open source.
-the screen on their best phone z30 has LESS ppi than even moto g. for over a hundred or so pounds you can get an lg g2 with over 450 ppi.
-it does not support gmail. you cant even sideload it.
-sideloading (android) apps on bb, albeit possible, are technically violation of DRM, legally speaking.
-you dont have google play. defeats the purpose of being able to run android apps.
The only, and i mean the ONLY thing that goes for bb is perhaps the security, which is also taken care of by android blackphone and samsung knox.
Oh by the way the z30 is not even splashproof, let alone being waterproof.
Perhaps one more thing about z30 is the paratek antenna, which might give better signal. though most other phones that are australian 'blue tick' are android, and even iphone falls into that category of blue tick as it apparently switches to using its secondary antenna on low signal.
