I have an iPhone 4 32 GB, i noticed lately a little gap between the rear glass and the stainless steel antenna band, see the link:

so i decided to fix this, just opened the rear panel and tried to close it again
but now, it won't close because of this small gap 🙁
please help, any idea

i managed to close the rear panel, but the problem persists, there is always this small gap
the problem as i can see is due to the battery

it is stronger on the left side. is this normal?😕😕
