Google's much-awaited Android 5.0 Lollipop roll-out for smartphones other than Nexus and GPE is a hot topic right now. As we step into 2015, there are a lot of pending updates that should be pushed to smartphones from Samsung, LG, HTC, Sony, Motorola and others.

Nexus and GPE smartphones are the first ones to get the latest Android updates, while other brand smartphones get a stretched-out delay. Things are finally looking up for high-end smartphone owners, who have been waiting for the major Android update for months.

Samsung

Samsung has a vast line-up of smartphones that are yet to get the taste of Android 5.0 Lollipop. Recent leaks have indicated the roll-out of Lollipop in select regions like Poland and parts of Europe.

In a note from a Samsung store employee on Wednesday, Samsung reportedly sent out emails to all executives with the instructions on how to update the devices to Lollipop. According to the rep, Samsung will first update its Galaxy S5 smartphone and then continue with its Note series. Last year's Galaxy Note 3 and Galaxy S4 smartphones are also in Samsung's list for Lollipop update.

HTC

HTC smartphones are great in terms of design and performance. Another tidbit of having HTC handset is guaranteed upgrades. As for the Android 5.0 Lollipop, a private leaked info reveals the flagship smartphones, One M7 and M8, will get updated to Android 5.0.1 Lollipop during the first week of January. That's great news for those who are looking to get their hands on the Sense 6.0 on Android 5.0.1 updated handset.

LG

LG is following the footsteps of Samsung as it is testing the update with phased roll-out of Android 5.0 Lollipop to handsets in Poland and South Korea. Like its home-country rival, LG is currently focusing on rolling out the update in Europe. LG G3 and G2 handsets will receive the latest Android update, but specific details are missing.

Motorola

Motorola smartphones are the lucky ones like Nexus and GPE handsets to receive latest Android updates sooner than other vendors. Even after being sold by Google, Motorola shares the same relationship with the web giant and promises timely updates for smartphones.

For some handsets like 2013 and 2014 Moto G models are getting the Android 5.0.1 Lollipop update directly in various regions around the world.

The company will likely follow the same feat for other models in the line-up such as 2013 Moto X, 2014 Moto X, 2014 Moto G, Droid Ultra, Droid Maxx, Droid Mini, 4G Moto G and the Droid Turbo.

Sony

Sony may be going through some rough times lately, but that doesn't affect the software roll-out for Xperia smartphones.

It is certain that the entire Xperia Z series, including Z, ZL, ZR, Tablet Z, Z1, Z1S, Z Ultra, Z1 Compact, Z2, Z2 Tablet, Z3, Z3v, Z3 Compact, Z3 Tablet Compact and Z Ultra GPE, will be getting the Android Lollipop update but there are no specific details on the release date.

However, Sony promised that the massive roll-out will begin at the start of 2015 so we can expect to hear some more news from the troubled tech giant.
