iPhone Apps and Icons Flickering
I bought my iPhone 7 plus 2 weeks ago, with an iOS 10.3.1, and it's the second time I noticed that the icons flicker from one icon after the other when I plug the charger to my iPhone. The first time I noticed this was 4 days after I bought my iPhone but I ignored it, I thought it's just a normal thing but this time it flickered a lot and I am a lil bit worried.. I had been using iPhone since 5 to 6plus and went to android for nearly 2 years and just got back to iOS, and this is the first time I have encountered this, is this is a big issue or problem..?? Anyone??
