Ensure module is high enough above props plane. Compass is mounted on the bottom of the module so ensure you have set roll 180 degree.

See, sometimes root cause can be completely different than we think. I hope you have followed guide of copter.ardupilot.com
There two important steps needs to be done carefully.
Compass and accelerometer celebration. Have you performed them as per guidelines given on the wiki? One more think ensure that compass is facing in correct direction(north-north). Also as i said check whethet roll rotation is set to 180 degree as the compass is upside down on the external module.

Does the Mission Planner HUD shows correct reading (ie E,W,N,S) when your copter is pointed to the respective direction?

I couldn't understand what does it mean. Are you experiencing altitude drop while flying?

This is a known issue with 3.1.5 where the quad jumps upto 2m when you takeoff first time in loiter or alt hold modes. It seems this was fixed in 3.2 (still in beta stage). And what about the compass problem? You said the quad was moving diagonally, is that fixed? Not all GPS module has compass at the bottom so you have to make sure while selecting rotation roll in MP.

Is there a way I can try 3.2 ? It doesn't go to 2m , it keeps on going up until and unless I switch the mode . I don't know about diagonal as the only testing I have done with it after the crash is by holding it with my hand inside my room .
Can you tell me how to test for compass ?

Yes! You can try 3.2 RC7 (which is the latest) from your Mission Planner firmware selection page (select beta firmware). It might be risky, I would suggest you to stick with 3.1.5 until 3.2 is released. Compass test can be done through CLI (Test-> Compass) or by looking in the HUD. My GPS module has compass on top of it so I had to set Rotation Roll as None (0). Make sure you check this physically or by performing the test.
