The latter is released in Switzerland alone for the unbranded Galaxy S5.  While there is also  another build version dubbed as G900FXXU1POFA for the ones branded and under "Swisscom" network. Noting that Switzerland hasn't receive any new updates recently, so the update might be the special build for the said region.  The update brings the Wi-Fi calling support which allows users to activate the voice calling over WLAN.

Along with the update are security enhancements, including bug fixes and further improvements to performance.

How to Update the Samsung Galaxy S5 SM-G900F to Official Android 5.0 Lollipop


Samsung always urge us to prepare the following important notes to consider before performing the software update.  I have also added some useful insights why you should follow this procedures to keep your  phone in safe.

Recharge the phone’s battery – You should make sure your device is fully recharged before performing the software update. Do not also remove the battery during the software update is in progress. A power failures may cause damaged to your device that might results as we so-called “soft-bricks”. If this happens your device may just stuck on Samsung logo or welcome screen and can’t reboot normally.

Backup important data – You should back-up your important files, including contacts, emails, messages, photos, videos, apps and other stuff. Like I said while during software update process is interrupted there is a possibility that your data stored from your device internal SD card may lose or deleted when a sudden unexpected failure happened and it forces you to perform a factory data reset which basically wipes your phone’s memory.

Ensure that your Galaxy S5 should still runs on the official Lollipop released build version and hasn’t been rooted – Your device should not be modified or rooted, there is a certain circumstances that a modified and rooted Galaxy S5 SM-G900F may not accept any official software update anymore or it can accept an update but it might harm your device once the update has made. Learn about the new Samsung KNOX security suite. Most known error that says ‘firmware upgrade encountered an issue, please select recovery mode in Kies and try again‘ or “Your device has been modified Software update are not available” you should try to avoid that from happening.

Update via Over-The-Air (OTA)


This is usually how the carrier branded or locked Samsung Galaxy S5, performs a software update.  This method is Firmware Update through over the air or called as OTA update, which most often  a notification message will directly sent to you from your network provider or Samsung and notifies you that there is a new update available for download.  If you did not receive any notification messages you can manually check for the update instead.  Doing this you may only tap on your Galaxy S5 SM-G900F Settings>>About Device, tap Software Update.
  • Find “Software update”
  • Slide your finger down the display starting from the top edge of your mobile phone.
  • Tap the settings icon.
  • Tap About device.
  • Tap Software update.

It will automatically tells you that a new update is available or your software is up to date when there is none yet. You can simply tap install now when you want to perform an update or install later. The G900FXXU1BOE5 Android 5.0 update is around 300+ MB in file size while updating via OTA.

Update Thru Kies

The second method is a firmware update through Samsung Kies. You may head-over to your  local Samsung support page from where you can download Samsung Kies from there, and install it in your Windows or Mac computer. Choose the new Kies 3 which supports the Galaxy S5 SM-G900F and other Samsung devices running with Android 5.0 Lollipop OS .  Once you installed Kies 3, all you need is connect your Samsung Galaxy S5 SM-G900F to the computer using the USB cable, then simply run and follow Kies on-screen software update instructions.
