While I'm talking on the phone, I noticed that there are some problems annoyed me quite a lot.
1. I couldn't enter the chat page on any messaging apps like whatsapp, line, etc.
but I could only enter the page showing the list of chats instead. (No matter I enter the app by launching them on home screen or by pressing the notifications)
2. the three buttons on the bottom have no response if I'm not on the call in progress page. Nothing happen when I pressed back button....
3. Tried using the Note small app to jot down some info while on the phone, the small app did launched normally but I couldn't input any thing in it since the keyboard is not popping up.
I am not sure whether I'm the only one having these problems or do I have something set wrongly? These problems are so frustrating since I couldn't reply to any message while I'm making calls until I finish my call...
I tried to factory reset my phone but end up these problems are still here.
