The Cubot S208 is the price / performance ratio a super smartphone, but with an enormous shortcoming! First the positives: The processing was with my copy very well and significantly higher than expected. Even the display is quite pleasant, despite the relative small size for this resolution. The biggest problem is the preinstalled Luncher who has a Trojan equal with integrated. After Avast Four and some other mobile antivirus software is a SMSAgent known as malware. Just genomes is the Cooee MSLauncher who also PlayStore has many negative recessions due to the Trojan.
The removal of the Trojan is only possible with root privileges and sufficient experience, as this is a Launcher System application and therefore not easy to "Settings" -> "applications" can be uninstalled. If the smartphone integrates no Trojans, it would be easily worth 5 stars.
Unfortunately, you can not upload more screenshots, otherwise I would have the Avast virus message uploaded.
In conclusion we can say that this phone has to be absolutely removed from Trojans, especially if you use mobile TAN or the like.
