Samsung Galaxy S4: Won't turn on or charge, recognises on pc.

Tue, 21 Mar 2023 17:41:53 -0700

So, my Galaxy S4 is totally unresponsive. It won't turn on or even charge.

The backstory:

The phone was working perfectly after a new battery. I tried resetting the phone using the volume-down-home-and-power-button method.

However, I read incorrectly and held all 4 buttons down (power, volume up, volume down and home).

Now the phone is just black; it won't turn back on or do anything. The only thing it does do is show up as a recognized device on my PC.

I have never connected it to the PC before, so Windows installed some form of driver. Whenever it's connected or disconnected from the computer, the PC makes the regular Windows sounds as if the phone is recognized—but nothing pops up.

Samsung Galaxy S4: No sound or mic during calls only.

Mon, 08 Jul 2024 13:35:25 -0700

So I've seen this problem on a few forums. The phone works fine unless you make a call. When you do, the mic and the speakers will not work. They function with any other application in the phone. The suggested fixes are firmware update (some claim this has worked) and the other is a reflow of the chip that handles the incoming calls(?). I know by the teardown which chip handles the sound on the board, but if anyone has encountered and fixed this issue before, could you give a brother a hand on where to aim the heat?

Samsung Galaxy S4: My phone wont turn on anymore even with fully charged battery

Mon, 16 Mar 2026 06:12:25 -0700

I charged my phone last night and left it charging until morning. When I went to turn my phone on it usually vibrates before the screen pops up but this time it did nothing, I put in a new fully charged battery in my phone and it still doesnt turn on. It has never touched water and has no cracks at all.

Samsung Galaxy S4: Power button stuck, phone won't turn on or charge

Wed, 16 Dec 2020 15:57:09 -0700

The replacement for this phone is currently in the mail but I am really hoping to get this one working for an hour just to get the pictures etc.. off. The power button is stuck down without any event (being dropped) triggering it. I took the thing apart and the actual little white button will not click anymore like the volume ones do. When plugged in, the red LED does not appear and it doesn't charge. If I take the battery out and put it back in the samsung logo pops up for about 2 seconds then the screen goes black again. Same scenario when plugged into the computer or wall except it is the charging logo. My computer does not register it as being connected. I've tried every combination of buttons recommended to me but it doesn't respond to any type of reset. I've also tried using someone else's battery which did not do anything. I'm avoiding taking the power button off because insurance does require you to send in the old phone and I don't want any charges for my handiwork.

Samsung Galaxy S4: no notification sound on text messages

Thu, 19 May 2022 19:31:18 -0700

I installed Go SMS Pro and Chomp SMS because I thought it would be cute to have the same emoticons that I was missing from my iPhone 4S.

I didn't like the way it looked, so I uninstalled and restarted my phone. Now, I don't get sound on any incoming texts, while everything else has sound. I went to General Settings and checked that everything is properly marked. I went into the message icon and checked the settings there as well—everything is properly marked. There is no mute icon in the top bar.

This is the weird part. When I go into General Settings > Sound > Volume > Notifications and change the tone, I hear it. When I change the settings through the message icon, I do not hear the tones..... help!

Samsung Galaxy S4: How much to repair lcd screen?

Sun, 03 Sep 2017 00:54:23 -0700

Hi,

Despite how careful I was with it, I managed to drop my Samsung Galaxy S4 and of course, cracked the screen in two places. Not only this, but the LCD is blackened out in some places and won't work.

How much would it cost to have it repaired and do you have a UK store/website?

Samsung Galaxy S4: Samsung Support Can't fix my phone due to corrosion/water damage

Sun, 21 Nov 2021 07:43:27 -0700

Hey, now i dropped my Galaxy S4 in water with a case and screen protector attached for about 5 seconds. Almost immediately i took out the battery and put the phone and battery in uncooked rice for about a week. I contacted samsung because after a week, the phone would turn on, however there would be no display on the screen, the buttons on either side of the home button light up as well. If i connect the phone to my pc, it acts just the way it did before the accident. I send the phone to samsung as it was under 1 year warranty and they send the phone back saying Corrosion/Liquid Damage. What should I do now?

Samsung Galaxy S4: Phone is charging without displaying charging icon.

Fri, 27 Feb 2026 02:00:00 -0700

I had my phone working perfectly fine until last night when my battery was nearly 1-2%. It turned off (obviously). But when I reached home and plugged the USB Cable, it only displayed a Gray battery icon with a static ring on it, and that vanished after a few seconds. I gave it sometime (half an hour) to charge. But it still displayed me the same icon.

I used my friend's S4 battery, the phone turned on perfectly. So I was sure that the phone is not dead, but the battery might have died.

I inserted my battery in my friend's S4, plugged the USB cable, and it started charging normally. This confirmed that the battery is perfectly fine. The charging port might be damaged somehow.

But I noticed something very unusual. After getting my battery 30% charged using my friend's S4, I took my battery back and inserted it back into my phone, turned it on, and plugged the charger. It didn't show me the charging icon. This led me to a conclusion that my phone's charging port is damaged. But after half an hour, I looked at my phone, and now it was 60% charged!

The sudden bump on left is my friend's battery being replaced by mine.

So now, I'm charging my phone without the charging icon. But I'm not sure if the hardware has issues or software.

Btw, even my computer doesn't detect any device when I connect it using the cable. Not even an "unrecognized device".

Any help?

Samsung Galaxy S4: Screen is displaying vertical lines of various color after drop.

Sun, 11 Jul 2021 22:42:04 -0700

I'm fixing a family members Galaxy S4 after it has been dropped. The screen is left un-cracked and is displaying colors in vertical lines.

The touch screen still seems responsive as it's making noise when I swipe to unlock the phone.

I've been told that it was dropped in a small puddle but the water damage indicators on both the phone and battery seem ok so I'm not sure if any water got into the device.

I have a drop box link with video of what the phone is doing here: https://www.dropbox.com/s/po72yjtach08d1...

Turning off the phone or taking out the battery didn't seem to have any affect. When booting up the distortions split the screen in two and flash different patterns on each side. When messages are sent the screen will turn on and continue these distortions until the screen turns off.

I'm pretty sure the screen connection popped loose but I thought I would ask for more opinions before I start taking it apart.

I've replaced PSP screens before and a laptop screen or two so with the proper guides I'm sure I'll be able to figure out how to disassemble and resemble the phone if the problem is just a loose connection.

If you require further information or tests please let me know. Thank you in advance for your input.
