Charging port issues? - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

Hi folks,
I've noticed a couple of odd issues with my ultra that I haven't noticed with any previous phone.
1. The charging cable gets noticebly hot when charging, specifically the connector and top third of the cable
2. When connecting my phone to my car for Android auto the phone is picked up for a split second then disconnects, usually have to plug/uplug a few times to get it to work even then sometimes it will randomly disconnect.
I've tried multiple chargers/cables for both issues, none of which changes anything.
Anyone else noticed similar issues?

Nope - I would suggest cleaning the port with a bent open paperclip and some contact cleaner or IPA - sounds like there could be debris, hairs or even something conductive in there.
If all else fails - sound like an RMA. .

Touch screen stopped working

touch screen replacement
I had the same problem on my Universal and opened it to find out what happened.
I found the cable connecting the LCD and touch screen completely twisted.
Someone has played with it turning the screen in the same direction for many times without unscrewing it every time.
I manged to fix it partially soldering some wires that had gone loose.
Some wires were impossible to handle so I need a new wiring cable (it's a bunch of single ultra-tiny wires).
Now screen, mike and headpiece work again, but not the touch screen.
Do you have any idea if such a spare part can be found anywhere?
Possibly that would solve also your problem.
Who can have spare-parts?

Hmm....
Actually, not only the flex cable is originally twisted and looks funny out of the factory, you cannot turn the screen in the same direction more than it should be turned (e.g. from opened clamshell it only goes 180 degrees clockwise and cannot be turned anti-clockwise other than returning into its original position), it is stopped from turning by the way the hinge is designed. It is done specifically to prevent just the thing you described.
Generally even when some wires detach, the cable still performs fine, as the wires are not isolated and bunched together, as long as they do not detach from the connector itself. The fraying can happen when the flex cable is reinserted into the main case too roughly or one time too many, as the opening is fairly small and both cables need to be bent a certain way to fit through and pulled through in a particular sequence. Your problem could be caused by a faulty digitizer, it is connected to an LCD and if LCD performs fine, yet you lost sensitivity, the problem is not with your flex cable.
Cables can be purchased on Ebay. And so can digitizers (they are around $17-$20, but you need soldering to get them fitted to your LCD).

[Q] Car dock and speaker phone problems

For the past 2 days, no matter what ROM I flash, car dock comes on at every reboot. I've never used the car dock app, so I'm at a loss as to why it starts up every time I reboot my phone. I exit out of car dock, and it doesn't start back up until the next time I reboot.
Also, every time a call comes in, or if I make a call, speaker phone is always on by default. Again, this happens on every ROM I flash, and it's only been happening the past 2 days.
I'm rooted, currently using Warm Z, with netarchy 4.3.2 cfs more havs.
I should also mention that I've tried multiple kernels with the hopes that maybe that would solve the issue, but sadly it hasn't. Any help would be appreciated.
Well I have no idea why or how, but both issues have solved themselves. Nothing was installed or uninstalled, and my phone is back to normal.
Anyone have any ideas at all?

I'm having the exact same problems with my G2. If the Evo and G2 are anything like many of the other phones out there, they use a magnet to switch into car mode.
My problems started when I first started using a belt pouch with a magnetic closure - before I knew about the magnet/car mode thing.
Has your phone been exposed to a magnet for any period of time?
My phone is doing the same thing! Did you find any solution?
On my G2 I did a SuperWipe and then installed a new ROM and the problem was solved.
I believe that the car dock mode is regulated by the pin out of the power cable. Recall it being that two of the ground wires are attached in the car dock and not in regular power cable mode.
Also in car dock application, you can go into the menu option and turn it off so that the car dock application isn't the default action when it senses that connection.
I actually own the car dock, but hate the application since I usually only dock the phone when in GPS mode.
Having the same problem.

I've had the same problem for a month now anybody find a solution really annoying at this point.
I had Car Dock starting for no reason on my phone. What I was found was that launching Car Dock was done so by certain pins in the Micro USB port on the phone. What was happening to me was that the Micro USB plug on my charger was messed up in a way that made the phone think it was plugged into the dock instead of just a regular charger. I bought a new charger on Ebay for like $3 and never had the problem again.
I've read that some people have Car Dock launch without their phone being plugged in. Almost all of them noticed that they had some sort of tiny debris within the usb port that was crossing the pins and causing the app to launch. Cleaning out the port with something like a toothpick should help eliminate that possibility.
Hope this helps.
Yes I read that as well, and tried cleaning the port with a soft tooth brush and compressed air and didn't help. the most annoying part is the load speaker is the default for incoming/outgoing calls and the media volume is stuck on full, much to load for headphones. More than likely the pins are touching and so small that I can't see them much less straiten them out. Trying to find someone who can solder a new port, so if anybody has sent there evo to have the port fix with good results I would appreciate a good recommendation.
thank

[Q] Why isn't my phone storing my preferences. ALSO CAR HOME FOREVER.

Two point five questions here I guess but I've tried everything and I don't know what else to do. Rooted phone, got it back in july not long after the launch. For the last week or two, maybe more, I was using MIUI with tiamat 0.7. Most recent version of both. For a while Car Home kept popping up always and being super freaking annoying. Eventually I had to freeze it with Titanium backup.
Another very bothering thing is that the audio output for media is incredibly loud. Like if I plug in some five dollar headphones and keep media on lowest, I can hear it about ten feet from the buds. Not even cupping to bounce sound, just sitting on a surface. I don't know what caused this but it may have been fault, I'm not sure if doing what I did, did this; I had a pair of broken headphones so I whittled and scraped them down just to the plain bare jack and use it as a soundkiller while I'm at work. I've done this before with no problem but this time I scraped down so some metal is exposed while the jack is in and I'm sure I touched it when I removed it. I did this for a few days and suspected it might be the issue causing the sound so I stopped.
I also wiped very thoroughly the phone and SD card and went to the latest nightly of CM7. Same issues, including car home so I'm not sure what the hell is wrong with that damn app. Also now my phone is ALWAYS rotating anything even when I tell it not to and keeps making itself silent as far as ringing and notes go. What can I do?
Tl;DR: Car home always popping up, Media sound is incredibly loud, CM7 is ALWAYS rotating.
I realized this was due to a loose connector in the headphone or usb port and the phone always thinks it is in a car docked or does whenever this is loose. I found an app called NoDock in the market, it requires root but it works on the OS level disabling the feature all the time when I want to meaning I can still use it. There is a trial that claims to work for 7 days however I've been using it for the day after I posted this until now. Another person posted in the market a bad review because his trial lasted only 30 minutes so it is a formula or something. Normally it is 3 USD so it isn't too bad.
The choices I had were using this with this app or getting a replacement through sprint officially as a damaged hardware. The replacement would be a brand new model that couldn't be rooted as of yet so I figured I'll deal with this. The evo is over a year old now and I can't be sure people will keep trying to do new things to root it so I'll keep my beloved.
I'm posting this so in case someone has the same issue and searches 3 years from now and sees this they will know what i did.
Car home is caused by pins getting crossed within the USB jack. Check for a few things:
1. Does it happen only when the phone is plugged in?
2. Is there any debris or the like inside of the USB jack that is crossing the pins?
3. Does the same thing happen when you plug another USB cable into it?
Mine did the same thing and it turned out to that my charger was screwed up and making the phone think that it was docked. So I bought a samsung charger off of Ebay for like $3 and it's worked flawlessly ever since. If there is junk inside of the phone's jack get a toothpick, or something similar, to clean it out and see if that helps. If the jack is clean and the phone still launches car home while NOT plugged in then your USB jack may be screwed up.

[Q] Headphone jack issues (hardware)

about 5 months ago, I started having a strange issue with my note. I would plug in the headphone jack and all I would get would be a very distorted, quiet version of whatever was playing. if I would tap the phone on the back, it would come across clear. Eventually, this stopped working. I replaced the headphone jack module completely. Immediately I noticed the problem again. I have taken the phone apart several times to check the physical connection of the unit to the board. It is getting to the point that I have to strike the phone against my leg or a desk pretty hard before it will start to play clear. I have secured the unit with tape, cleaned the contacts on both sides and used 2 new modules to try and fix the issue. I can find no information on this in a search.
Anyone have this issue? or any ideas?

WiFi/Bluetooth replacement?

Hey (first post!)
I was replacing USB charging port flex cable by myself (and for whatever reason decided to unscrew the main board as well, but put it back in place right after). After I put everything together I noticed that my WiFi signal is extremely low. Also tried connecting to my Bluetooth headset but it has very weak signal and can operate properly within 1m distance, otherwise it starts stuttering and finally disconnects.
So I figured that I might have damaged WiFi/Bluetooth board and need to replace it. However I cannot find any spare parts for it anywhere. I only found one for OnePlus 5 but it seems that most of the parts are different between 5 and 5T.
Any suggestions please?
