> Apple, known for supposedly delivering sleek products, launched in 2010 the iPhone 4, still under the tutelage of Steve Jobs. Within hours of release, users flooded the internet to complain about dropped connections and abrupt reductions in internet speed. The problem, according to Jobs, was with users holding the iPhone 4 with their left hand [8]. As this was a hardware issue, it was never really solved.

They did fix it with later versions of the iPhone 4 and with the iPhone 4S. Also, I remember that they made the "bumper" cases to alleviate the issue with the antenna: https://apple.fandom.com/wiki/IPhone_4_Bumper
