How to move apps to SD card on the Lenovo A850

lenovo a850 narrow

Welcome to another tutorial on the Lenovo A850. Today, we’re tackling an issue that’s one of our biggest bugbears about this handset – the miniscule amount of internal memory included with the phone. Once you have the core apps installed, there only about 1.5 GB free to use which is increasingly becoming to little to be practical. This is one of our most-requested tutorials so please spread the word to help out others struggling with this problem.

For this simple step-by-step guide, we’re going to be using a Lenovo A850 and using the Flashtool software to directly install software that adds the feature to move apps to your SD card.

The ROM we’re using is the S123 Lenovo Stock ROM and, as well as letting you move apps to the SD card, it includes the Google Play Store and gives your the ability to install other custom ROMs later if you want to.

Before we start though, a disclaimer: by flashing over USB or installing custom ROMs, you may be voiding your warranty. We take no responsibility if your phone is damaged or bricked by following these instructions. Always backup your phone before altering its software in any way.

Initially, you need to make sure you have installed the Lenovo USB drivers. Download the drivers and the Flashtool as well as the ROM file itself.

To install the drivers, turn off the phone (don’t use the quick boot option) and take out the battery. Open up Device Manager and plug the phone in via USB – be ready to quickly right click on the device that appear and choose “Update driver”. Using the wizard, select the drivers you downloaded previously. If you are having issues, installing the drivers, use USBDview to ensure that you have deleted any existing MediaTek USB drivers that might be on your computer.

Next, unzip the ROM file and make sure you can open Flashtool on your computer. You are now ready to start following the instructions in the tutorial video below.

All the downloads you need to follow this tutorial are linked here:

Flashtool + Lenovo USB drivers
Lenovo Offical English S123 ROM (v.2.3.5a)

Please let us know how you got on with this tutorial. Also, give us your thoughts if you find the amount of free space on the A850 limiting? If you have an external SD card, what size do you use?

    hi.. I clicked on the download link you provided for the ‘Flashtool+Lenovo USB Drivers’ and it took me to the same site (
    where i downloaded the file ( i can’t run it…
    please please help me… how and where can i download the correct file.. hope to hear from you very very soon…

    Great Video but I’ve got one issue:

    I clicked on the download link you provided for the ‘Flashtool+Lenovo USB Drivers’ and it took me to the following site

    The site allows me to download the file ( onto my PC without any issues. When I try installing the file though, I run into a ‘brick-wall’. It seems to be bundled up with a bunch of other softwares and requires me to install them (lightning downloader, PCBackup etc) alongside the flashtool.

    I selected ‘accept’ for all the requirements and went ahead with the installation only to end up with all the softwares EXCEPT the Flashtool and the USB Drivers installed. I’ve tried removing the files and re-downloading it from the same link and it’s still doing the same thing.

    Am I missing a few steps here or is there something wrong with that link? I’m using windows 7, 64-Bit . Thank you in advance.

    Hope to hear from you soon.

      Which service are you then using to download the files? It sounds like you’re clicking an advertisement on one of them (for some reason you don’t have adblock installed?) rather than the actual download link and hence getting spyware instead of the correct file. Please try again using a different service and ensure you don’t click any fake download buttons.

        Hey Guys.

        Thanks for the quick reply. I guess I messed it up earlier by clicking the wrong link.

        I just clicked the second link and I’ve got all the tools I need, so I’m going to get started with the flashing. Thanks a heap !!

    I am using ROW S128. It also has a Move to SD Storage button but not a Default Write Disk option.

    Is it moving Apps to SD storage when I press the button? Or, do I need to install S123?

    Thank you so much! Tried the steps above and everything went OK. I can now move apps into my SD card…

    Just a minor issue; for some reason I can no longer save contacts on my phone; all contacts can only be viewed by navigating to my Google contact.

    Plus, names will no longer appear when I receive calls; I presume that this is due to the fact that my phone’s contact is not synched with my Google contact.

    Am I missing something here? Any help would be appreciated. thanks! 🙂

    • Mobile Network Comparison 2 September 2014 at 03:02 Permalink

      What does it say in your Google Account settings?

      • Ahmad 2 September 2014 at 05:17 Permalink

        It doesn’t say anything. It seems that now there are TWO contacts on my phone; one if on the phone itself and the other one is from Google. If a person from Google contact call me, there won’t be any names on the call screen. 🙁

      for those who complain that they couldn’t download the usb lenovo flash tool and driver better try this–> http_//www12_zippyshare_com/v/6691867/file_html but first replace the “_” with “.” and in front of the http with ” : ” then u can proceed. Plus the usb driver is included in the folder SP Flash Tool. The folder name is Drivers. Good luck~ I hope this will help you out there.

  73. mrtz 2 April 2014 at 08:36 Permalink

    thanks for the great teaching, but the ROM was not correct and can’t move the apps to SD. it just changes the partition format and still save in the same 4GB internal storage.
    But teaching the process of upgrading the ROM was excellent.
