iPhone 6 problems after upgrading to iOS 11
Iam using iPhone 6 from last few years and I had no problem with it unless and until I updated with iOS 11. Initially I thought the software had bugs and it would be rectified but it followed with consecutive problems my incoming speaker became too low to hear (loud speaker is perfect) and even while playing a minimal graphics game its getting heated and to that my apps take time to open which is annoying. So, can you give me a better solution or else at least help me with the downgrade option to 10.3.2 (ipsw10.3.2 download link).
Thanks
