Samsung irked its fans by bringing Android Lollipop update to its flagship devices long after handsets of other mobile phone makers got it but it may not be the case for the new firmware. It is reported that Samsung devices such as the Galaxy S6, Galaxy Note 5 and others may get Android 6.0 Marshmallow OTA (over-the-air) update soon.

Google's latest software, Android 6.0 Marshmallow, is already being rolled out to devices like Nexus 5, 6, 7 (2013), 9, Nexus Player and Android One smartphones but yet to reach handsets of several other mobile phone makers.

Android 6.0 Marshmallow that comes with several features like apps permission, fingerprint support and Android Pay, app drawer, enhanced battery-life through Doze and Google Now could come to Samsung devices sooner than expected though exact release schedule is not known.

The South Korean electronics giant is silent on software update for its devices but T-Mobile has listed Galaxy Note 4, Galaxy Note 5, Galaxy Note Edge, Galaxy S5, Galaxy S6, Galaxy S6 edge, Galaxy S6 edge+ and Galaxy Tab S2 among the devices that will get the new firmware update. 

"Devices listed here are currently preparing to deliver a software update," read the note on T-Mobile support page, hinting that it could come anytime in the next few months.

Gottabemobile reported that it may take some time for the firmware to be rolled out to the public as internal testing has to be done at T-Mobile. 

With T-Mobile having announced Android 6.0 Marshmallow update for Samsung devices, other carriers Verizon, Sprint, AT&T, Vodafone, Bell and US Cellular could follow suit.
