Blackberry lost its place in the smartphone market a couple of years ago just like Nokia. However, after it was acquired by TCL, it started hitting the headlines again. Reports have it that
BlackBerry DTEK50 and DTEK60 are currently receiving the February security patch. Although the complete changelog is not available, we know that it comes with fixes for Spectre and Meltdown – the former gives unidentified persons access to your browser and the hacker can get stored passwords.
This update is about 100MB in size and it is designated AAU660. As of now, we can not verify the extent of the roll-out of this update but it seems that unlocked units in many areas are getting the update. Thus if you own these smartphones, you should head to settings to check for software update. If you do get it downloaded, let us know how it worked out for you in the comments.
