At this writing, Mobile World Congress 2015 is happening, and many of the new Android phones such as the Samsung Galaxy S6 and the HTC One M9 are promising to have the latest version of Android version 5.0 (also known as Lollipop or Android L) right out of the box. However, Samsung users of the Galaxy S5, the Galaxy S4, the Galaxy Note 4, and the Galaxy Edge still have not received the Android 5.0 update, depending on their carrier.
Samsung Galaxy S5
I mentioned a while ago that the Lollipop update had arrived for the Samsung Galaxy S5, at least for Verizon. Since I am a Verizon subscriber, I was pleased that I was able to download Android 5.0 and have it work very well. Sprint also has Lollipop available, and I have heard that T-Mobile has the update as well. As for AT&T, Gotta Be Mobile reported that the Lollipop update is confirmed. This means that everyone should have it, so check if you are a Samsung Galaxy S5 user.
Samsung Galaxy S4
At this present time, a recent report from Custom Today has reported that the Samsung Galaxy S4 in Europe should be receiving the 5.0.1 version of the Lollipop update, and that it has already been made available in both Russia and India. However, any S4 with an American carrier like T-Mobile, AT&T, Verizon, and Sprint will not have this update.
There is another leak that the Lollipop update is on its way as Android Authority has posted evidence of the Samsung Galaxy S4 running its Lollipop 5.0.1 update. The translated source did not say where the file came from, but it looks like the firmware is official and important functions such as Wi-Fi, network data, NFC, Bluetooth, and sensors are working just fine. Galaxy S4 users can go to the XDA developers site and attempt a download of it for themselves, but do this at your own risk.
Galaxy Note 4
As for this phablet, the most recent source at the Lation Post shows that only T-Mobile has confirmed the Android L update on the Galaxy Note 4. As far as the release date for the Lollipop update on the Galaxy Note 4 is concerned, the latest update as reported by Tech Radar shows that Samsung is in the process of updating. The Galaxy Note 4 Lollipop update is actually readily available for customers in South Korea as well as Poland.
Samsung Galaxy Note Edge
As for the Galaxy Note Edge, this is the word from a tweet by Danny Dorresteijn, the co-founder of a respected fan site SamMobile, the "Note Edge to receive Android 5.0 in February". Well, we are finished with February, and there isn't a lot of updates being seen. However, we did report at the end of February that T-Mobile's software update page reported a whole list of devices that were going to receive the software update, and the Galaxy Note Edge made the list.
This still leaves questions about other Samsung phones and phablets like the Galaxy S3, Galaxy S5 Mini, Galaxy S5 Active, Galaxy Note 2, and the Galaxy Alpha, and it is doubtful that they might ever experience the Lollipop update. If you are a user of these devices, check your settings menu for System updates.
