Apple's two failed iPhones in 2025

The interest in the iPhone 17 series is high, particularly for the iPhone 17 Pro and iPhone 17 Pro Max models, which are outselling their predecessors. The iPhone Air has a different tale to tell; sales haven't been great, with reports showing low demand and major production cuts.  In contrast to the heavily publicized flop of the iPhone Air, there hasn't been much info on how the iPhone 16e is doing in sales. Early reports suggested it was doing pretty well, but it seems that wasn't up to Apple's standards.  Sales of the iPhone 16e and iPhone Air aren't meeting Apple's expectations, as per info from leaker Fixed Focus Digital (source in Chinese). While no exact figures were shared, the leaker suggests that Apple's effort to launch a popular, budget-friendly iPhone hasn't succeeded.

Downgrade Galaxy S6,S6 edge, S6 edge+ from Android 6.0.1 Marshmallow to 5.1.1 Lollipop, Yes You Can!

There has been a lot of questions via our contact page surrounding the Galaxy S6, S6 Edge, and even the Galaxy S6 Edge+ Android 6.0.1 Marshmallow updates. Some folks may not conveniently  satisfied how's the Marshmallow performed according to their own experienced. Some may complain about some lag issues, whilst others complained about some of their daily used or important   apps that may not tend to work any longer.

Majority of these folks were asking if they just can temporarily downgrade back their devices from Android 6.0.1 Marshmallow to Android 5.1.1 Lollipop just like the way it was before but may then get back to Marshmallow until it stabilized further.

You can do read these Marshmallow issues in forums and social media.   Now, to keep this post short and straight forward, "Can we really downgrade our Galaxy S6, S6 edge, and S6 edge+ from Android 6.0.1 Marshmallow back to Android 5.1.1 Lollipop?"

Devices with unlocked bootloaders can be freely downgrade-able, but those with highly secured bootloader cannot be messed around.

How to downgrade the Galaxy S6, S6 Edge, and S6 Edge+ from Marshamallow to Lollipop?


The only way to downgrade the device is to re-install the Android 5.1.1 Lollipop in to the phone.  You can do so by using flashing the official Android 5.1.1 Lollipop stock firmware.

Refer to the following pages according to your phone type:

The process is not that way difficult on some part but just could at-least you return back your phone the way you like it better.

Yet again, don't just take my word on it, you can only confirm this method if it will work or not out of your own.  It's you phone and not mine, so it is still up to you to decide of what to do what can you do about it.
