My galaxy s10 is not connecting to pc/otg - Samsung Galaxy S10 Guides, News, & Discussion

After last update my phone is not connecting to pc. I checked the installed drivers and updated them. Also tried different cables and tried on my laptop as well. It is charging but not showing up on windows. It is also not detecting otg drives. Any help?

Clear system cache.
Hard reboot.
Check all associated settings as the update may have altered them.
Never update if your OS is fast, stable and fulfilling it's mission. Security for Android 9 and above is not a major concern unless you do something stupid. Not a valid reason to update.
Cause there's no saving dumb bunnies...

Me too, but with a S10e, waiting for next update.

MHL kernel wakelock problem

I am totally stock, unrooted.It all started after I turned on Google Now. I was trying it out for a few days, didnt like it so I turned it off. After that, I noticed a considerable dip in battery life. After checking with better battery stats app I found that the phone would no longer go into deep sleep and the culprit was "mhl-kernel-wakelock". I have tried everything to get rid of this wakelock.
I have tried: phone reboot, battery pull, wipe data from all media player apps and usb service, deleted all my apps, reinstalled them. I tried a full data wipe/reset and wiped cache.I tried charging my phone while off. I deleted all my media off of my sd card and got a new sd card. I tried connecting to windows based pc. Nothing works, the wakelock remains.
I have never used my note 2 to connect to the tv or anything like that. Also my usb functionality no longer works. It wont talk to the computer. The phone will charge though. I have searched google extensively and there is very little information regarding this wakelock. I'm afraid it might be at the hardware level. The only other thing I can think of is buying an MHL cable to HDMI and hook it up and hopefully when I disconnect it it will shut off the MHL mode that it is stuck in. Obviously I could also root and flash a ROM with a different kernel, but I really enjoy stock and the spen features etc.
If anyone has any suggestions im wide open. Thanks
EDIT (2/1/13): I also realized that when I tried Google Now was around the same time that my house lost power during the night and the power flickered WHILE my phone was charging from the wall outlet. I initially attributed the problem to Google Now, while in actuality it makes much more sense that a power surge fried my USB port on my phone.
I know this probably isn't the answer you were hoping for but I think it might be a good idea to go ahead and, assuming you're comfortable doing this, root and unlock your device. I recommend you try out Jelly'Beans' Build 4 ROM. It has all the great features of stock with the bonus of being much lighter on your phone (smaller system ROM file) and you can set it up to look like AOSP Jelly Bean. Or if you really don't want that look and prefer TouchWiz, you can do that too.
I would do this anyway as imho, it's better to be unlocked and free for the remainder of days you own this device, rather than get an OTA and lose the possibility of unlocking ever again.
And this has a good chance to resolve your situation as you would be totally wiping the system partition and chances are thats where the issue is.

back up whatever you dont want to lose and wipe data/factory reset from stock recovery. you can try a cache wipe first, but a data wipe will fix guranteed.

Thanks.I already tried this several times. I tried it from the OS and from the recovery. I also lost my usb functionality so im not even sure if I can flash a new rom with odin.
I think I'm screwed. I can't even access the hidden menu from the dialer pad to attempt change the USB mode. It looks like a hardware failure, even though I haven't done anything out of the ordinary. It would explain why its stuck in MHL mode with the constant wakelock (despite multiple factory resets and data wipes). and why no USB ( tried 3 different cables) cable or any number of computers (3 different computers) cannot recognize, connect, or exchange information with it via USB. This blows.
I registered with Samsung and am trying to fill out a service request through their website, but it just says the troubleshooting guide is unavailable right now and it won't let me get past that step to actually request a service repair. FTW
Just an update in case anyone has this problem. I was able to get the battery drain under control. However, I'm not absolutely sure which setting it was, but under screen settings it was either auto-rotate or screen timeout, but I pretty much changed them all back to default, rebooted and changed them back to the way I liked them. For some reason it disengaged the MHL mode that it was stuck on. This is even after 3 factory resets and data wipes.. all it took was to switch one of those on and off.
The other problem I had was that my USB hub quit working, although it would charge, but not communicate with any computer. After a couple more days though, it stopped working altogether. It wouldn't charge my phone or do anything. I tested my charger and cord with another phone and computer it works/charges flawlessly.
After that, I took it into Verizon (crossing my fingers, since I got my Note II on release day with no insurance... so way passed the 14 day return period) and told them that I did get my phone back in late November, but I had never tried to plug it into my computer since I got it (even though I had and new about this problem for awhile) so I told them it was probably defective from the release date, I just didn't know about it. Long story short, after talking with 3 of the reps and them mindlessly googling dead-end solutions that I had already tried, the manager issued DOA on my device and shipped me a new Note II for free.
F yeah... very happy at this point. The new one I got is not a refurb, runs flawlessly. I rooted, unlocked, and running Clean ROM... all right before the OTA hit.
facing same problem with mhl wake lock and my n7100 note 2 is not detected any more when connecting to PC

Not charging when plugged in... Sometimes...

So I'm having a strange issue. I've already checked multiple threads, here and on other forums, most notably this one: http://forums.androidcentral.com/samsung-galaxy-note-2/263592-note-2-wont-charge.html
I read every post and no one has my exact issue. So here's the story:
I smashed my screen to bits on concrete, but I have the insurance so Asurion sent me another one. I'm not certain it's refurbished but It did not come in the same packaging my original one from the VZW store did so I'd say it probably is.
I made a backup of my rom using TWRP (Clean Rom VZW Edition - JB 4.1.1)
Then I got my new phone out and checked it and it was running the vramc3 version, so i tried to root/unlock/install recovery via the NoYou exploit. This failed due to driver issues, then after that was sorted out, failed again due to a partitioning issue. ("error: partition 60 blah blah...") So I tried to odin back to stock without realizing the newest firmware had to be flashed using the alternate stock rom for unlocked bootloaders (even though mine was not unlocked) so i flashed that and it worked, i was on the original stock firmware again. however the older version of the exploit for the stock firmware did not work (i'm assuming because the bootloader wasn't actually rolled back even though the firmware was) so i downloaded the ota updates and got back to vramc3 and tried the NoYou exploit again and it worked, so i had root, recovery, and an unlocked bootloader.
Because my old phone and new phone have different serial numbers, I modified the folder name and .log file entries of the TWRP backup of the old serial number to be the new phone serial number. This worked and my phone was restored. For 3 days it charged just fine, and then last night and all throughout today, I've been testing it after noticing it doesn't charge when connected to an a/c outlet, and does not recognize a connection to my pc..... SOMETIMES. Sometimes it works right away, other times it takes 10 minutes of being plugged in before it recognizes it. and other times it'll sit for an hour and never figure it out. All without me moving it around too, i really don't see how it could be a cable connection issue. I tried my old phone on the old and new samsung official a/c charges and both work flawlessly every time, so i'm certain the cables are good.
So i did some more testing. I tried doing a factory reset with the rom still installed. Still had charging issues. I tried wiping everything except my external sd card and installing the latest version of the rom which is based on the vramc3 update (fresh install, not using my backup), still doesn't always charge...
I didn't yank the cable out, drop the phone, or mishandle it in anyway in the past 3 days, and the leads for the usb connection on the phone don't appear to be damaged. I also tried moving the cable around the connection while plugged in to see if something wasn't making contact and it didn't make a difference. I also now have 2 batteries, both hold a charge perfectly fine, and charge perfectly fin in the old phone so I don't think it's related to them either, and I have tried the new phone with both batteries. So here's the question....
Is this a firmware issue, or a usb port issue? I still have the old phone and if it's a usb port issue i'll just swap it with the old one, but i'd prefer not to take it apart until someone more qualified to speak on the matter tells me that it's the problem, haha.
And if it's a firmware issue, what the hell do i do? since I have recovery operational, i was going to try a few other roms just to see if anything changes while i'm waiting for replies.
Pleeease help, as you can probably tell by the length of this post, this is driving me insane.

This topic can be closed now. I looked up a video (http://www.youtube.com/watch?v=FfvOTFssDMM) of the swapping process and saw how easy it is, so i just went ahead and tried it, and it totally worked, so now it's charging fine again. Thank you to anyone who viewed this and hopefully this can help someone in the future.
I didn't read all of that. I was at a concert last night. But here what I know about the not charging thing.
In my experience
1.all the good galaxy phones do it.
2. Its not that it wasn't charging. Its that vzw turned the power up on the modems. If your in a low service or weak signal area your phone will actually drain the batter faster then you can charge it.
So if you notice this is happening. Switch your phone into airplane mode. Or turn off mobile data and let it charge for a while.
I have read about a few case's where the usb ports where disconnected. But I think the crazy fast radio battery drain is way more common.
I don't know if its the same for other carriers but I know a note guy a s4 guy and 2 other note 2 guys we all had the same problem with it.we are all Verizon too.
The original modem flash helps a lot but the 2nd one that went out ota is stronger in weak signal areas so we all use it and turn off our data if it gets to much.

USB Completely Disabled After Updating to Oreo

Not sure if this had been posted before.
For a good part of last year and this year, I have been looking far and wide for a solution to fix my USB connection problem after updating to Oreo. I cannot seem to get my PC and MAC to recognize the device anymore.
All of my USB settings are grayed out, i tried turning it back on in developer mode and still no results. My USB port is NOT grimy, I keep it clean.
Roaming the official Sony forums for a year caused me so much anxiety, since there were no solutions, mostly complaints.

SAME! Could you fix it?:crying:

Stopped receiving updates, even security related

Hello guys,
For the past 4 months, i haven't received a single update on the phone, and manually checking shows I am up to date.
The phone, however, is stuck on Android 10 with July security updates. Is there anyway I can manually update to Android 11, or force the phone to find the update?
I have tried clearing the cache from recovery and cache, data of the software update app.
Thanks!
Welcome to XDA
I make sure you really want Android 11... and all it screws up. 10 was the last good OS version before Google went scoped storage nuts. A fair amount of members here have rolled back to 10 after getting a taste of 11.
Unless you do something stupid the security risk you're taking is minimal. Just make sure (as you should be doing anyway) that all critical data is redundantly backed up to at least two hhds that are physically and electronically isolated from each other and the PC.
Rule #1- if a Android OS is running fast, stable and fulfilling its mission... let it be.
Thank you for your response. I get that maybe the new version is not that good, but I would still like to have the option to update!

Question SM-A526U T-Mobile Stop Automatic Updates

Hi all,
Every time my phone automatically downloads an OEM update, it's telling me to update my phone, and I can defer the updates after 4 times. After that, I can't defer the updates. It just updates automatically, and each time, my phone is getting slower and slower and slower which I don't want at all.
Also, auto-update system is off on developer options. So I am at a loss now.
Not sure if there is really anything you can do about it. My phone doesn't seem any slower.
Are you absolutely sure it's the update that is slowing down the phone?
yep

Sorry for the late reply. I'll admit I do have a good chunk of apps in my phone, but it's an experience thing that I have with samsung phones.
When I had the S9 (from verizon, not sure on model), I still kept Android Oreo because I took use of a software bug that let's you keep your android version without updating your phone, and one of my relatives, same phone model, was updating their phone to the latest version because they have to after a certain number of defers. Note that I do have a good chunk of apps on my old phone, but my phone was a lot faster and responsive than my relatives phone, being that their phone only had a few apps and mine having more apps than theirs.
If I have to update the phone, then I will update the phone. I don't want an automatic update, and then all of a sudden, different problems occur that has never happened on the last build.
