The program will be going on through to at least July, though the last few versions would have come in August, so keep that in mind.
The Android Q beta has just been turned on and we’re set for a crash course over the next several months. Since Android Nougat, the finalized version of the OS has been published sometime in August with Android Pie having been pushed out the earliest.
To be clear, Google has not and never has placed specific dates for dropping software updates, but we do have a general idea of how the next few months will play out in the beta program.
