Samsung Galaxy S5 Random Factory Reset

Yup, here again. Setting up my Samsung Galaxy S5 after a random factory reset. Unfortunately, in today’s connected world the phone has become the linchpin of my techno-geek world. My two-step authentication system ensures it takes an extra 20 minutes to log into any service I care about when my phone is MIA. Thousands of messages, contacts, and other data needs to be re-downloaded into the phone so I know who (843) 555-1212 is on SMS or when a telemarketing agency is calling. It takes HOURS to reload all the moving parts.

Galaxy S5 Reloading. Again.
Galaxy S5 Reloading. Again.

What a huge pain!

Turns out I’m not alone.

Random factory resets of Samsung Galaxy S5 phones are a known phenomenon that apparently Verizon and Samsung are content to ignore. Too hard to reproduce so it must be user error. Or a bad app. Couldn’t possibly be an issue with Samsung’s hacked version of the Android OS or bad firmware, right?

Android Lollipop Barfing

The most likely and most common problem with the random factory reset appears to be related to corrupted cache files in Android OS after a system upgrade. Interestingly, all 3 times that my phone decided to just reset for no apparent reason it was within 2 weeks of an Android Lollipop update pushed out by Samsung.

Very coincidental, isn’t it?

Turns out that the fix is… A HARD FACTORY RESET.

Wonderful. The only solace with that fix is that you may get to spend the two hours reloading your phone during a time in your life when it is the least inconvenient.

Really not much different than a random reset, but at least you know its coming.

To start the process power off your phone then hold down the power, volume up, and home button at the same time. When you see the loading screen with blue text at the top you can release the buttons. Follow the on-screen menus to do a full factory reset and data wipe.

Yes, this is like getting the phone for the first time. Yes it sucks. Yes you will need to reload all your stuff (you do use Google and Samsung and a third party backup service right? You’ll need all 3 if you don’t want to re-invent the wheel every time this happens). No, your home screen, keyboard, and other configuration settings will not come back. Now you know why so many Samsung S5 users have the default screen. Why customize when you’ll be back to that default in 3 months whether you like it or not.

Bad Battery

Very rare.  However if your battery is defective it will overheat and warp.  Take the battery out.  Put it on a flat surface.  If it does not lay flat on the table you need to replace the battery.   Good luck getting it repaired under warranty.   Luckily batteries are inexpensive.

Bad Apps

Some sites, typically Samsung or Verizon-driven forums and support personnel, claim apps can cause the factory reset.  Sure.  Very unlikely as that is a HUGE security nightmare in Android OS, but I guess anything is possible.   The suggested fix is randomly delete apps that were loaded on your phone until the problem goes away.   Uhhh… exactly how often does a random factory reset happen?   That is like closing your eyes in a dark room, spinning around in circles, and trying to pin-the-tail-on-the-donkey without ever turning on the lights to know if you were successful.

Personally I think this culprit is nothing more than fairy tales and pixie dust to keep you busy and away from the support people.

Samsung OS Updates

Ultimately I think Samsung and Verizon need to stop screwing with the base Android OS builds to cram in a ton of crappy apps nobody wants.   Those apps are nothing but modern day spam that most people don’t want.  They consume excess memory and screen real estate with the only purpose being to line the pocket books of Samsung for hocking other people’s wares.   Wake up.   Nobody wants your crap and if they could delete all the force-fed shit on the phone for more memory and storage space and less app problems they would do it in a heartbeat.

Stop “tweaking” the OS and make a stable version that does not randomly reset every few months.

IOS – The Gold Standard

Sadly, if they ever DO make that version there will be more-and-more people like myself that will refuse to install the update for the ever-present fear of incurring the curse of the random reset.   Instead many people will be in the same situation I am.  Just waiting for my 2-year contract to expire so I can finally stop fooling myself into thinking that Android will every be a gold standard.   iPhone IS the gold standard which is readily apparent by every single device-and-service you could ever want to use granting Apple front-of-line status and relegating Android users to play the role of red-headed stepchild.    Starbucks.   BMW. Smart Lock.  Smart Home.  And big luxury brand has full-feature apps on IOS and half-baked crap and Android.

MacBook Pro Video Problems Solved

I’ve posted about this a few times on this site and now I feel like a fool for not discovering the problem sooner.     I’m not 100% certain if the issue is an HP monitor issue, a cable manufacturer issue, or and Apple hardware/OS/firmware issue.   All I know for certain is that a couple different brands of cell phones will cause my monitors to lose video signal and “flicker” on/off or show video artifacts.     Sometimes the video loss runs in cycles as fast as 1-second on/ 1-second off.  Sometimes the monitors power off for minutes-at-a-time.     Sometimes I just see horrible bands of pixelation run horizontally or vertically on the screen.    In many cases OS/X starts logging all kinds of video events in the system logs, but I am certain that is a side effect of a video data error that is not being handled as well as it could be.

At the end of the day the problem is easy to fix.   Move my cell phone away from my monitors.

Turns out that ALL THREE of my phones, an older HTC Incredible, a newer HTC Incredible 4G LTE, and a brand new Samsung Galaxy S5 all cause the problem.    It also turns out that the problem varies in intensity based on the lunar cycle and its alignment with the solar winds or some other cosmic crap like that.     What I do know is that when the problem starts my productivity goes to hell and as I can never guess when I can see my code or my browser.

For some reason the electro-magnetic fields (EMF) from the phone are causing all hell to break loose on the displayport video communications to/from the monitor.   That causes a cascade of problems which inevitably results in a monitor powering off or a black screen where video should be.     After multiple red herrings, running down innumerable rabbit holes, and even going so far as to not only swap video cables and monitors but also a brand new MacBook Pro,  the real issue is basic electro-magnetic interference and the solution is as simple as “move my cell phone”.

Here is the recap I sent to Apple Support today regarding the issue.   Hopefully someone will stumble across this online and save themselves some headaches as well.

 

Apple Support Communication

I finally figured out the monitor flicker, power cycle, and pixelation artifacts problem with my monitors after MONTHS of dealing with the issue.

This is really crazy, but it is without-a-doubt what is going on here:

PROXIMITY OF CELL PHONE TO VIDEO HARDWARE

I haven’t yet narrowed down the issue to exactly what the root cause is, but here is what I know for a fact:

1) This happens with my older HTC Inredible 4G LTE phone.
2) This happens with my new Samsung Galaxy S5 phone.
3) This happens ONLY on displayport but HDMI does not appear to be impacted.

4) The problem appears to only happen with the phone is within 5cm of the monitor end of the displayport cable.

5) The problem happens on the HP ZR2440w monitor and other HP monitors using DisplayPort as well as a Samsung monitor using DisplayPort  (I no longer have that monitor, wish I could re-test).

6) Portrait or landscape mode was a red herring.

7) I could not reproduce the issue by placing the phone near (even touching) the MacBook end of the displayport cables.
After 5 days of trying to capture the behavior with my camera-phone and the problem suddenly going away after picking up my phone it finally came to me.      Move the phone back and TOUCH the display cable… bam powers off the display like a wireless power switch.     Move it away, pixelation, then the monitor comes back on.

I then tested the FIRST displayport as I have only seen this happen on the 2nd displayport (furthest from power port on the MacBook) and like magic the first monitor turned off as soon as I touched the phone to the cable.

After multiple tests I’ve learned that I need to just be close to the cable (it is not a physical cable connection issue, verified that a few times).   Within 1-2cm the monitor powers off 60% of the time.   Within 2-5cm the monitor may power off (10% of the time) or display pixelation artifacts or the notorious “ants” problem (30% of the time).

It *may* be the minidisplayport-to-displayport cables I am using, however I have swapped out these cables and at least one set of cables is NOT from the same manufacturer.

To be determined:

a) Is this a cable shielding issue?
b) Is this a monitor build issue?

c) Why does the software react to EMF introduced at the hardware level?   (bad error checking/trapping in the video processing firmware/software?)

Just though I’d share so you can close this ticket and possibly disseminate this information to support channels.     I’m guessing my cell phone is not the only possible source of EMF that can cause external display issues.   Given the number of online posts about similar problems I would venture a guess that more than a few Apple support calls and hardware returns may be related to similar EMF-related issues.

I am very techy and know all about EMF but it never occurred to me that the EMF from my phone would affect a displayport signal to the point of being able to actually power down a monitor IMMEDIATELY.

Good to know what it is.  When I have more time I’ll do more homework and post my findings online.

In the meantime I’m relocating my phone charging cable to not be under my monitors.
