Reflection seem to be in the middle of handle and not evenly distributed + final apk render setting!

We are developing an android app from unity, So far unity is great, easy and i am quickly getting thing done until now, I have several issues with unity graphics for android:
1: I have a handle made with a simple shader as shown in imges which reflect world and dose odd things with reflection probe - images are provided. Actually once in the past i was able to achieve exactly what i wanted as shown in the image, but as we moved files and project marge, every thing was bad, gone through all the setting i can find - lighting, graphics, quality,render path, shadow, and other.


2. I have this aliasing problem in final apk. Not in my Oneplus3 and axon7 but in others like honor7 and old phones. In older phones the graphics is super bad worsted i have seen.

Note: i have tried suggested quality, graphics , player , editor , shader , renderpath setting for past week. But i am still new and this is my 1st android project on unity. Help Plz!

images below are some of the screen shot from apk, perfect.png is what i want and i had in my old project file - different unity project file.

How do i remove that reflection of stuffs in the middle of handle? ... it looks fat and edges look messed up!
