So what do I do now? The battery in my Acer Liquid Zest Plus (not even 2 years old) has popped up like a microwave popcorn bag and warped my case and expanded so much that the screen is popping off of the front. Doesn't seem to have affected the phone's functioning at all. I know the battery has obviously overheated but seems fine now. I can't afford a new cell phone right now, please tell me it's ok to keep using.
