[T-Mobile Samsung Galaxy S 4] MultipleMonomials:
I've become pretty exasperated with these phones lately, so I thought I'd share my experience. My question is: are these phones supposed to be this fragile?

It started two years ago: due to Verizon's discontinuation of unlimited data, I'd convinced my family (me and my parents) to move to T-Mobile. It seemed like a great deal: we could finally upgrade from our Galaxy S Fascinates, and the plan was cheaper too. Me and my dad, both power users, chose S4s, while my mother, who was more of a casual user, picked the S3 since it was cheaper. At first, it seemed great: the S4s were powerful, and the screens were awesome. We purchased the insurance, but neither me nor my dad bought cases, and my mom got an aftermarket back for her S3 with a swing-closed screen cover.

Fast-forward two months later. My mom's S3 started rebooting randomly, especially during periods of high use. It got so bad that we were considering replacing the phone, when I noticed that I could trigger a reboot by running a CPU stress test application. This pointed to a battery that was going bad and couldn't always provide enough voltage to keep the phone running. We replaced the battery, and were off on our merry way.

Over the next year of heavy use, the silver coating on the band of plastic around the front edge of my S4 started to flake off. By summer, it was totally gone, exposing the white plastic underneath. Meanwhile, my dad's S4 had developed an odd issue with the screen , causing vertical bands of color to be visible. It wasn't a huge issue, and he didn't seem to notice it.

After the first year, it all changed. A new issue cropped up first in my dad's, then my S4. It seemed that dirt had gotten inside the case, underneath the proximity sensor. The screen became more and more reluctant to wake up during calls. Dad could seem to keep his in check by canned-airing through the speaker grill on a regular basis, but I had no such luck. Once I hit dial, my screen would turn off for good unless the other person hung up, or I put my phone in a spotlight or direct sunlight. Eventually, I had to start pulling out the battery to hang up a call. I could only check my voicemail by plugging in headphones.

Then came the cracks. That autumn, it happened, that thing all phone-owners dread: After surviving several multi-foot drops with only dents and scratches, my S4 fell off of my leg when I was sitting on the ground, landed upside-down, and developed a small crack off to the side of the screen. It wasn't bad, but I was kind of shaken, since up until then I'd considered my phone screen to be pretty much invulnerable. Then, a week later, it fell only a few inches out of my pocket onto a stucco floor. It landed directly on the screen, and I heard an unholy cracking sound. I picked it up to find two cracks stretching diagonally from the top left to the bottom right of the screen. We discussed getting a new phone, but I decided that it wasn't worth the insurance deductible, especially since I would get a phone with the new KNOX bootloader. Later on, I dropped it another couple times, and the display shattered in a few places.

A few months later, Dad's phone's SIM card holder started to fail. At first, whenever he went for a bumpy motorcycle ride or otherwise shook his phone around, the S4 would lose cellular signal until he rebooted. It got worse over time, to the point where he was rebooting multiple times a day just to stay connected. I decided to do some troubleshooting, and, with his agreement, ODINed it to 4.4 touchwiz with the KNOX bootloader. It had been over a year, so we figured that the warranty had run out. This got results, as soon after booting up the phone it would show an error, "SIM Card Removed!" I guess that the other rom hadn't had this error, and just lost signal when the card momentarily disconnected. Anyway, we contacted T-Mobile, who gave him a new SIM card. The problem persisted, and he had to wait a long time at the store while it was being provisioned. We proceeded to call the insurance, who told us, surprise surprise, that buying the insurance also comes with an extended warranty. Which I had just voided. Now, Dad was really angry, since he had to pay $150 for basically no reason. We got the refurbished phone, but he refused to let me root it because that would void the warranty, and he didn't want to have to pay the insurance again. Instead, even though we had Titanium and Clockworkmod backups of everything, he painstakingly rebuilt all his user data by hand. And so the story ended. Or so we thought.

You see, about a week after he got his replacement, the screen cracked. He didn't drop it; according to him it just spontaneously happened. It wasn't very noticeable, and it wasn't a big deal.

Two days ago, his Wi-Fi just stopped. Completely. It wouldn't turn on in settings. Neither would Bluetooth. He did some research, and it turns out that a common issue with refurb S4s was that the internal Wi-Fi antenna would not make good contact with the mainboard. He went to a T-Mobile store, and found out that that little crack actually voided his warranty, so all of that manual rebuilding he did was for nothing. So, he took apart the phone according to a YouTube video, cleaned the antenna contacts, and put it back together. He turned it on, and it was still broken. Oddly enough, it worked for a while after uninstalling some apps, but it soon broke again. Desperate, he gave it to me in hopes that it was a software problem. I tried two different ROMs, but the issue persisted.

So, his replacement phone is a bust. The thing is, he refuses to consider any other phone because he goes through two or three batteries a day, and needs a phone with replaceable batteries, and these are becoming endangered species nowadays. So, he's going to get another S4 from the insurance company, which might be just as unreliable.

Meanwhile, Mom's S3 is still running Android 4.1, and has given us no trouble since the battery thing.

We owned our fascinates for the same amount of time and never had any hardware problems at all. I gotta think that this isn't normal. Are we unlucky, abusive, or is this actually the normal failure rate for these phones?
