Avoid to lift only the display instead of the whole phone assembly as doing so may cause damage to the screen.

Use an iSclack or a suction handle to separate the phone assembly from the rear panel.

In case you can‘t manage to lift the phone assembly out of the rear panel you can insert the pointed end of a spudger in the headphone jack opening and press the phone assembly upwards until you create a gap between assembly and rear panel. Then use the spudger to lever the phone assembly out of the panel.

Don't remove the rear panel completely yet. There is a cable connected to it! It is running from the finger print sensor to the display unit.
