Ok, so I got a new phone (The Android Admire) for Metro PCS a few days ago. I want to download some applications but it says I dont have enough Internal Storage. I went and Cleared the Cache & Data on things I dont need at the moment. It still says I used 189MB with 7.9MB left. I go to "Sort by size" and it says that myMetro is taking up 144MB out of 189MB used. I wanted to know if it was safe to clear the data on it without messing up my phone.
