qqp question1: I have GPU implementation as a graduation project. Is there any recommended material? question2: Xperia zr screen cracked - I went to the nearest authorized service centre in salt lake and they asked me to pay 11000 bucks (too high for a 2 year old mobile) as the repairment cost of my damaged screen. So I'm confused from where I'll get my mobile repaired. Either I can purchase the material from eBay or visit a local store as an alternative. It's really difficult to trust a local store regarding material and the cost. Please provide an approximation of the price and advise me for the same.
