I want to have an application: "Visitor" mode on the phone

With the trend of technology integration, we can be surprised to find that, for now, more and more users in the hands of the mobile phone is not just a communications device. In just a few years, mobile phones have begun to show the trend of replacing many digital devices. Although at the current level, whether it is the level of music playback, photo level and file processing capabilities, the mobile phones are inferior to those with the exclusive use of their own equipment (MP3, digital cameras, computers), but it has been able to meet the needs of many ordinary users. And these also let the handset start a very private portable device. In contrast, our own phones are easy to borrow. And at these times, do we have the same concerns about privacy being seen? And how many friends with the same small, want to have a mobile phone end of a visitor mode? In our daily life, we may easily borrow the mobile phone for various reasons, and the information in the mobile phone is displayed in front of people, such as contact person, text message, photo, etc., even some account password. Most of the time we do not want these things to be seen, but for the other person's request also embarrassed to refuse, we will be caught in a dilemma. And this time, if there is such a app, we call it the mobile phone visitor mode app, we just need to borrow the phone before we start the app, we can follow some of our preset settings, such as hiding text messages, photos and so on. In this way, we can not only ensure that the personal data will not be leaked, but also not because of the refusal to lend the phone to create embarrassment. For mobile visitor mode app, we need it to have several functions as follows: 1. You can customize the information displayed in guest mode. 2. You can save a variety of different settings for Guest Mode 3. You can record what is done in Guest Mode 4. One-click to clear all settings changes in Guest Mode note: Perhaps many friends would like to have such an app in their mobile phone, but at the same time small set to remind everyone, let alone in the technology of this app will not be difficult, and its appearance means The loss of protection of information. For an app like this, it naturally gets our highest system privileges, and the functionality we envision allows it to take over a lot of system applications to capture all the information on our phones. Imagine that if a company can master so many user information, even in the background to let mobile phone to do the operation, we may face a very small crisis. So, if similar applications come up in the future, we might want to consider whether app developers are enough to trust us.
