BlackBerry OS 10.3.1
BlackBerry OS 10.3.1.1154 has leaked for BlackBerry 10 devices.toptechanalyst

A new Blackberry OS 10.3.1.1154 has been leaked for the Blackberry 10 running smartphones. Along with the autoloaders links, the radio and core OS download links as well as apps from OS 10.3.1.1154 are available for the BlackBerry Passport, Z30, Q5, Q10 and Z10.

According to the findings shared by members at the Crackberry forum, the leaked OS version is snappier and less laggy when compared to the previous 1151 version. Things are much smoother than earlier, such as picking a contact, going to call screen or placing a call. The 1154 OS seems to have fixed the battery graph bug.

However, there are a few hiccups here are there. The teamviewer is reportedly not working and has poor Wi-Fi connection. Also the green flicker in videos (on Passport) is not fixed yet.
