my iphone doesn't have 3d touch is it normal

Rumine,

Check If the screen on your iPhone, iPad, or iPod touch doesn't respond to touch - Apple Support, and read the topic titled:

Adjust your settings for 3D Touch

Please verify the model number at: Settings - General - About - Model = ???

Rumine,

If your touchscreen still doesn't respond like it should, contact Apple Support or take your device to an Apple Retail Store or Apple Authorized Service Provider.
