How to Hard Reset the ZTE Grand Memo V9815 (Easy Guide)

Specially created for Europe, the ZTE Grand Memo V9815 was officially launched in March 2013. Since that moment and until the present days, this high quality smartphone attracted the attention of a great number of clients. Its 3G and 4G networks, as well as the 16 GB of internal storage capacity and the quad-core processor might be three of the many reasons why it became so popular.

If you are the proud owner of this device and you recently begun experiencing an increasing number of failing apps, errors, hangs and other software issues, you might be dealing with a virus. These ones can easily be caught when transferring files from another device onto the ZTE Phone. In order to get rid of all possible bugs and regain functionality of the phone, we recommend doing a hard reset on this ZTE Grand Memo V9815.


Running on Android OS v4.1.2 – an operating system that is also known as Jelly Bean – the smartphone comes with a non-removable 3200 mAh battery. Apart from that, it comes with a strong Wi-Fi 802 hotspot and can reach 100 Mbps DL in terms of speed. It is equipped with a Stereo FM radio and it has two cameras: the primary 13 MP one it attached with geo-tagging and can also film 1080p videos while the secondary one is a 1 MP camera.


Although we did insist on the importance of performing a cold reset, we’d like to come back to that and tell you that a soft reset can also be a solution. If you’re only dealing with some minor problems, and the general functionality of the ZTE Grand is still at moderately high standards, it might not be as difficult as you thought. For this option, you should press and hold the Power button until the phone shuts down. Remove the battery afterwards and reinsert it after a few seconds. If things are the same as before, you’re safe to move on to the next step.

As we’ve mentioned in the beginning of this article, the master restore procedure is very efficient in removing viruses from the phone. In order to do this, though, it is necessary to remove all files that are stored on the internal memory. Given how large the storing space is, you probably have many important files, as well as photos and music you’d like to keep.

We’d like to recommend making a backup before getting started – this one is easy to do and there are various options. You could store everything on a cloud, transfer files on your PC or tablet or you could use the PhoneCopy application. The latter is able to guide users through all the steps that are needed to save all necessary files.
