You’ve never experienced need any of that at all?
This is feedback I’ve heard from borderline anti Apple folks. Part of the reason they went with android is so they can control how their phone performs even if it is generally a crappy experience for the average user but you get the control “needed” by intelligent / not mindless Apple sheep / tech savvy power users.
This is feedback for mostly galaxy phones and nexus phones.
Older Samsung phones with older Android sure. Not today's Android. Android is not a crappy experience by any measure. Android has a much cleaner look than iOS (imo). Do not look at store demo models as they always propel Android at its worst. I can't even stand it.
I've owned numerous iPhones and numerous Android devices including the new Samsung S8+. In fact, over the holidays I bought an iPhone 8 matte black because I love how thin and light the phone feels in my hands. But over 5 days I couldn't take iOS anymore and took it back to go back to Android.
My issues were the following: iMessages full of bottom clutter further squeezing the input text box off the screen. Increasing the super tiny font to something I can read with less than perfect 20/20 was still hard to read for me and had inconsistent font sizing issues through-out iOS after increasing it. Android uses a much more readable font size by default. I cannot understand why iPhones use such small fonts on their phones. It may work just fine for you and that is perfectly ok.
Everything was mostly white and black text and text and text all over the place. Android uses a material design look with colors and a nice flat design, and with the aid of Nova Launcher everything has a consistent clean look. Emails are easier to read, Contacts are easy to read. I prefer Signal or Textra for my text messages. And one of the most infuriating things to me was being a Linux user I had no easy way of getting music on and off the phone. Another pick I had was the default ring-tones and notification sounds are teeth grating to me. Seems it's such a pain to add your own that everybody that has an iPhone leaves the default sounds as everywhere I go, I hear the same ring-tones and text message sounds from an iPhone noob. When I'm in a group setting such as in a waiting room and someone gets a text message you see everyone glance at their iPhone because they all have the exact same sound settings.
I am not here to bash iOS or any iPhone user as people prefer what they like or are used to. In fact, I recommend iPhones to many people as it's a very respectable platform. This is only my personal experience and my own personal opinion which is pretty meaningless. I am not here to convince anyone to change platforms or argue a better platform versus another. Not worth my time. Use what you prefer the most and be happy with it as I am with mine.
