Android ADB commands to get the device properties

adb shell getprop ro.build.version.sdk

If you want to see the whole list of parameters just type:

adb shell getprop

From Linux Terminal:

adb shell getprop | grep "model\|version.sdk\|manufacturer\|hardware\|platform\|revision\|serialno\|product.name\|brand"

From Windows PowerShell:

adb shell getprop | grep -e 'model' -e 'version.sdk' -e 'manufacturer' -e 'hardware' -e 'platform' -e 'revision' -e 'serialno' -e 'product.name' -e 'brand'

Sample output for Samsung:

[gsm.version.baseband]: [G900VVRU2BOE1][gsm.version.ril-impl]: [Samsung RIL v3.0][net.knoxscep.version]: [2.0.1][net.knoxsso.version]: [2.1.1][net.knoxvpn.version]: [2.2.0][persist.service.bdroid.version]: [4.1][ro.board.platform]: [msm8974][ro.boot.hardware]: [qcom][ro.boot.serialno]: [xxxxxx][ro.build.version.all_codenames]: [REL][ro.build.version.codename]: [REL][ro.build.version.incremental]: [G900VVRU2BOE1][ro.build.version.release]: [5.0][ro.build.version.sdk]: [21][ro.build.version.sdl]: [2101][ro.com.google.gmsversion]: [5.0_r2][ro.config.timaversion]: [3.0][ro.hardware]: [qcom][ro.opengles.version]: [196108][ro.product.brand]: [Verizon][ro.product.manufacturer]: [samsung][ro.product.model]: [SM-G900V][ro.product.name]: [kltevzw][ro.revision]: [14][ro.serialno]: [e5ce97c7]
