I have fonepad 8 since 3 months ago. The screen light appears dim/brighter for few seconds then light normally especially when pre open an app. It was happened since first time I bought this pad. At the beginning, I thought its caused by the OS version but in fact, even I had updated it to lollipop version, the problem still exist. So far I don't know whether caused by lcd or OS problem. We need feed back from Asus how to solve this. Thanks..
