Sharing in the profit and loss in a partnership

Q: There is a company called 3A Alliance. The comapny take's money from people for investing. They have a motorcycle company called Supreme. They take your money in advance which is RS,21 600. The total amount for the bike is RS,36 000 and they say that after 35 days we should come take the bike or sell it back to them. It means that they sell it to other wholeseller's across the city and once you have invested this Rs,21 600 amount they order a bike by your name every month and sell it to other's and give you some of the profit which is Rs,3500. It sometimes goes up and down every 2/3 month's

Is this halaal or haraam? The company also deals with other home appliannces like TV, refrigrators, water purifiers and they also say that if you don't like our company you can take whatever it is you have invested.

Finding something that looks like a cross on one's phone

Q: Recently I bought a new phone that is designed to be waterproof and it is designed to be such that if it falls from a table it doesn’t break or crack the screen.

A problem, however, is that the designer of the phone placed two steel platters over the phone’s back (I think it is intended to protect the battery and the back of the phone). I know picture making is haraam so I did not take a photo for you to inspect. The two steel platters cross each other and it looks like a cross (two steel platters crossed together, with the upper part of the vertical platter shorter, which is similar to a cross). I personally don’t think the company intended to make a cross shape to appeal people rather the designer probably just thought that this design is either safe or “cool” (it is a Chinese phone company and they are likely not Christians).

Should I return the phone or keep it? Returning it makes me feel a bit guilty as there is no product defect. But keeping it also makes me worried. If I keep how do I destroy the shape (it is made for safety so I don’t know how to remove the platter)?
