Had my KEYone for a little over 3 months now. Just discovered that the back of the phone is slightly separated so now there's a gap. I was able to push it back down and decrease the size of the gap but you can see the back is still clearly separated from the phone. Is there an actual fix to this? Is this worth the hassle to contact Blackberry? Also, how would I be able to check if the cause of the lifting is due to a swollen battery?
