Answer to "Could heat from heat gun misalign Home button and data port?"Heat can cause the plastic in the charging port to warp which sounds like thats what happened here as now you can not fully insert the charging port to charge the unit. Unless you put pressure on it. Did you get a new screen with adhesive and a home button already on the new screen? Or did you transfer the home button to the new screen?
Answer to "Power button not working after screen repair"I'm have the same exact issue too. Did you find the a fix for this?
