Nope. Installed on 2 iPhone 6s and an iPad 2. No issues, wireless connections (WiFi and Cellular) both rock solid. From your recent postings I’m thinking you need to switch platforms. You are obviously disenchanted with Apple’s offerings. Why stick with something you detest? Move to a more mature, better QA and worry free platform like Android or Windows Phone. You might be happier. It’s worth the try instead of being unhappy all the time.
