A lifting screen combined with any puffiness likely means a swollen battery — stop charging and using the phone and get it serviced promptly; never press or pry on it.
Symptoms

- Screen feels loose when pressed near the edge
- May be paired with a slightly puffy feel to the phone

What to do
- Stop using and charging the phone if the lifting is paired with any puffiness.
- Do not press the screen back down or try to glue it yourself.
- Photograph the gap to show a technician exactly where and how much it's lifting.
- Keep the phone away from heat, which can worsen battery swelling.
- Take it to a repair shop promptly, since this is often a battery safety issue, not just cosmetic.
When to call a pro
