In the last weeks I went to RSA Conference to hangout with a few people. I met the good guys from NowSecure and Zimperium as well as the fellows of DuoSecurity.
The week after I attended Qualcomm Mobile Security Summit 2015. Again this was a super interesting mobile security focused event, most likely the best one of the year. Good talks and good people. There is no general posting of slides but some presenters published their slide deck. Tim and jcase posted their slides here: Android APP Protection. It was good to meet some guys from @K33nTeam. Their presentation was pretty good too.
If you are interested in learning about Android security take Jduck's and Zach's training at DerbyCon. They know what they are talking about.
This picture is sadly very true. I really dislike the trend going towards big smartphones or phablets.
Nexus 5 issue after a long and painful struggle including factory resetting my Nexus 5 and downgrading it to Android 5.0.1 I gave up and determined that it must be a hardware fault. Most likely the power button. I also found out (via @mweissbacher) that the warranty of our Nexus 5 devices ran out in January :-(
I determined that the only decent device to buy right now is a Moto X in the Pure Edition. The pure edition is basically AOSP like shipped with the Nexus devices. So if you are looking for a normal sized smartphone that runs stock Android this might be a device for you. Motorola even states on their site that the pure edition receives more regular updates then carrier branded devices. Most likely also more frequent updates then devices that run a heavily modified Android version (shipped by most other manufacturers).
