I have a Verizon Samsung Galaxy S3 model SCH-I535 and I was having an issue with the charge port causing a desktop mode to pop up when plugged into my truck. This was effectively preventing the phone from charging because the screen would stay on. I read on a forum that perhaps the pin was bent down slightly closing a circuit that was only intended for certain after-market peripherals like a desktop dock. I noticed that it was in fact bent down, and I tried to gently bring it up, only to break the piece altogether. Now it won't charge or recognize any usb connections. I've begun externally charging batteries and swapping them in the morning and evening, but this is a real inconvenience, especially when I think it could just be replaced. I believe it's within my skills to solder the micro usb port, however I can't find a verifiable source for the part. I'm not under warranty, as I've already replaced the screen once. There's a part on this website called witrigs (unable to post url) that claims to be appropriate, but there isn't much information there. Can someone verify that this part would, in fact, work with my phone, or is there perhaps a better place to find parts?
From what I have read the gs3 needs a hot air gun to desolder the plug not exceptionally difficult but does require the right tools and there is several things close to the plug that you need to worry about.
I think I'm capable of the replacement, but is there anything specific to the micro usb for this device that would prevent a more generic part from being used?

Hi friends
I am having an handset(Tilt) with flex cable problem, but wondering if flex cable can solve my phones problem where it is doing the following:
-Not accepting the SIM.
-phone is getting hanged any times, speed is also very pathetic.
-keypad is pressed on its own.
-Phone is not accepting any charger but charging with PC USB.
These are some of the major problems, I wish if someone could help me out in knowing what work does a flex cable plays, coz the technician is charging so much to change the flex cable & giving me no assurance as to what problems will be solved. I would like to know from some of those technicians here who knows something about hardware. Mike I am talking about you specially.
I would like to write this in our XDA encyclopedia given the case I get proper knowledge about it.
Looking forward to answers.
This is quite difficult to answer without testing. The SIM not being recognised will in itself slow down the phone or even create a full blown crash.
It's not stated what flex cable we are talking about. Flex Cables are just multi wire connections between circuit boards. Phones often have 3, 4 or more flex cables. For example between the the physical keypad and the motherboard or the d-pad and the LCD screen or between screen and motherboard etc etc.
It IS possible a flex cable can get damaged. This normally happens in phones with a slide out keyboard where the flex-cable has to roll back and forth as the keyboard slides in and out. However, such a cable would not I think change the charging behaviour of the phone.
It charges on PC connection but not charger connection. To me that normally indicates a USB port connection problem - bent pin in the slot, possibly even crossed pins or a cracked or dry solder joint between the usb port and the motherboard.
Another thing to consider is whether all the battery contacts are making good contact with the phone. Here again the multiple connections between battery and motherboard can become dry or cracked leading to erratic or underpowered connections.
The keypad being pressed on it's own can again be caused by different things:
1
It could be a faulty or loosley connected flex cable
2
Pressure being put on the digitizer screen by something under the bezel or just a damaged digitizer layer
3
A key that is not releasing from the keyboard properly (is it always the same key or group of keys?)
4
Moisture at many different places inside the phone, including keyboard, d-pad etc. Even when dried out, the residue or oxidisation can continue to cause problems.
So, I would not rule out a flex-cable problem, but it might not be the only fault. Unfortunately then, the technician you spoke to may be correct and it is not possible to guarantee it will solve all problems. Having said that, I would want to say to the technician that I am not going to pay for a new flex if it does not solve any of the problems.
This is where it becomes difficult to decide whether to go for paid for repair or to attempt the job yourself.

Hi
I have major problem with my tablet and usb socket has been pried from board have taken a quick look at damage and a replacement or solder of new one is out of question and metal contacts on pcb has been damaged also.
I am wondering if anyone knows a way of bypassing so I can still charge.
Can I bypass the small circuit board where USB connector is and hard wire battery connections directly onto USB itself.
This tablet has always served me so well dont want to give up on it just yet as cant afford a new one.
Fairly confident with soldering etc just curious as to whether it will work and best way to wire it up
Hello XDA, here's something that has bugged me for a while.
I think everyone has experienced the tired out micro USB cable issue. You know, when the cable won't charge your device unless held at the proper angle, or when it won't even stay inside the device and just slips out. I believe this is caused by the little hook pins on the bottom of the plug getting a little bent or worn out.
This happens to me a lot. I operate heavy equipment all day and my phone is always bouncing around while charging. I think this bends the micro USB plug and I have to replace my micro USB cables like every couple months. Sometimes more.
So my question is, is this an issue with usb-c? I've searched online a lot and can't seem to find anything on it. This issue is a big deal to me since I'm pretty rough on my cables. Is it going to be a problem? Has anyone had this issue with a usb-c cable?
Thanks a ton everyone

I would like to also ping this thread as I am wondering the same thing. My last 2 phones required me to start angling the cables so that they would charge (likely based on the wear and tear of inserting and removing the cables).
So, is the design of USB-C more, less or the same reliability as micro-USB from a port longevity perspective?
Ok, I have a realme 1 that is dying, I have posted on the new phone thread but I do not expect to get a phone that meets my needs better in all aspects.

Hi everyone, This thread is a continuation of this thread. This is here so you can discuss what your next phone/tablet should be, if you're not sure what to pick. Also, if you need advice as to which device is better than another, then feel...

The issue is that the micro USB connector is getting worn down and the battery discharges in a few hours. Even new I used to have days on which my battery 3950mAH would be exhausted by the end of the day.
I want to do the following thing
Replace the micro USB port with a USB C port. physically my phone is a plastic fantastic and I plan to carve/shave out the few mm with a knife/scalpel and fill any voids with a combination of expoy putty and expoxy glue. My problem is how to do the internal wiring. I have done some soldering but nothing on a PCB. The most fine work I have done is patch speaker wires. Every repair person i have talked to says that it is absolutely impossible to do. I would appreciate it if someone could walk me through it.
Realme has now released phones with a 6000 mAH battery, So I propose to separate the back cover, carve any obstructions, create any posts needed with epoxy putty, and fix the battery with hot glue. Again the problem is the connections. I realize that the thickness of the phone will increase due to this and plan to fill the gap with epoxy and hot glue.
Yes, I realize that my phone is going to be a Frankenstein's monster. As long it works well I don't care.
I would appreciate it if someone could guide me

You know you can get a USB C chip for really cheap (compatible with the processor)? All youd have to do then is attach the ribbon cables, enlarge the port hole and test to see if power passes through with a cable. Make sure not to use too much glue, however, because when the phone heats up the glue may melt and run over the motherboard, resulting in a ruined phone.

There is actually a YouTuber that I conveniently forgot the name of... But he does DIY projects like this, like adding a headphone jack to iPhone 7s and stuff. Call if modding. But his parts come from Chinese marketplaces. I would suggest you research a USB C component chip. Not sure how old your phone is but they are basically universal depending on the OS supported hardware (like Android 9+ supporting QC3.0).
Thank you again for replying. I do not need quick charge. It came with 2A 10 W chip, and that's enough. Cannot I connect the USB C port to the input on my phone. Most USB C implementations are USB 2.0, SO that SHOULD be 4 pins and 5v at max 2 A.
Problem is that that the repair centers are assuring me that is not the case.
Fire HD 10 Tablet (64 GB) Without Lockscreen Ads (2019 Release)
Been using and loving Fire Toolbox since January 2020 or 2021.
I had an old micro-USB port wire connected to my computer. I still use it for a music player. I couldn't remember if it was my usb-c for my newer devices (wasn't wearing my glasses), so I tried to plug it into my Fire 10 HD to see if it fit.
I might have pushed a little bit, but not with any force. But my Kindle will not turn on. Tried various combinations of buttons I read about to restart, reboot, etc.
Can old micro-USB cord cause a short if pressed into a USB-c device? The answer must be yes.
What are my options? Thanks
Will someone send me a Darwin Award cap. I'm willing to wear it around my house for a few days.
Figure out what was damaged. Inspect C port for damage. Replace C port pcb if this is an option. May have damaged the mobo...
It seems like I should be seeing more posts from a few years ago where people damaged usb-c devices trying to plug them into micro-usb chargers. And it wan not a force thing; it was a soft but firm, is this the right charger press.
It also seems like this would have been accounted for when the usb-c was designed, making it so that the previous standard, if used by accident, would not damage anything.
I am not able to see any damage. Maybe a magnifying glass will help.
I'm not sure if there is a tech repair section on the forum here, or if it is mostly software and mods.
If I search for a cheap, used, replacement, 32GB with adds, for example, is there any way to swap out internal parts and make it 64GB no adds.
Is there anything salvageable inside?
Thanks
Use a bright led flashlight or sunlight and a magnifying aid of some type.
That's a mistake I never made. Inserting a micro usb upside down... yes, well. C ports are more robust as well.
The C port can be replace but it requires a skilled tech as that mobo mounted one can easily be damaged from inept desoldering attempts. Most Samsung phones use a separate C port daughter pcb so no need to solder to replace it.
A local tech shop might do it for $30-50, the part itself is like $2.35
