So this is not really a big deal, but I noticed that the USB connection is pretty sensitive on my phone. When I plug it into my PC and wobble on the USB Type-C connector or push it into the phone a bit, the connection to the PC gets lost for a second. Is anybody else experiencing this?
Also, I can get a maximum transfer rate of around 35 MB/s, which is maximum USB 2.0 speed. So does the phone actually have the capability to reach USB 3.1 (C) transfer rates?

Hi all, 1st post, but I promise I have searched.
I have a SPV C500 and cant seem to get my car charger to work. I seem to recall that someone once told me that there is a difference between a charge cable and a data/sync cable.
This almost makes sense given that the phone will not charge when connected to a USB port, unless activesync is installed. What does activesync do to allow the charging to work? A charge cable, that worked with my cigarette lighter to USB would be great in the car, but it would also be useful in situations where I am at a PC without activesync installed (often at internet cafe's which prevent installing software).
Hope someone can help

What does ActiveSync do to allow the charging to work?
Click to expand...
Click to collapse
this is most likely because your computer dont turn on 5volt to power on usb before devices are recognised and activesync make that happen
hmmm .... interesting
I have measured the voltage coming from my USB port with a multimeter, which is just 5V. If this is directly off the USB port, without activesync running, then the PC is supplying a constant 5V.
I have also measured the voltage from my car's cigarette lighter adaptor, guess what, also 5V.
There must be something in the phone which makes it "accept" the 5V input.
I cant figure it out tho, is it something to do with the data pins? do these need to show the phone a certain resistance or something (such as dead short) before it will allow the phone to charge?
Seems to have the USB charging disable?

my micro usb cable's port dropped into water, as after 15 min of drying it when to connect it to my cell with my pc, firstly my cell switched off, after switching on it only charges my cell, no mtp mode is coming, no usb degguging is getting on, do anyone knows isnt my cells usb port had gone wrong or my usb cable's one ? plz rply fast !
I would say the copper in your cable is rusty, so data transfer probably couldn't be done since data transfer need more ideal conditions than normal charging

I recently got a LG G3 and I want to use it the same way I did my RAZR (XT912). I had a OTG cable going into the data end of a y-splitter (USB data in with a USB power and a mini a in) with the power end going into either my computer or a USB wall charger and the mini end pulling from a USB hub. The result being I can use multiple USB inputs and it was able to charge the phone as well.
With my G3 I was able to get it to find both my HDD and my flash drive I have going into the hub as well as a PS3 controller plugged directly into the hub but it won't charge for some reason even with my USB devices unplugged from the hub. I did notice periodically my clock app will show a charging symbol next to it like its charging even though its losing power.
Is it possible that I need a stronger power signal going into the y-splitter for the G3, a new y-splitter, or a entirely different setup?
I really don't want to have to root it if I can help it but I'm thinking that might be why its not allowing power in. Then again I'm not a master with this sort of thing so I could be wrong.
Also if someone knows if there is someway to get Slimport to work with charging and OTG input that would be good to know although I don't think that is possible
***update***
So I dug out the ac adaptor for my USB hub, then hooked my G3 up to the hub like before with nothing else in it and left the screen off for a hour or so and it charged it like 2% even though it said it wasn't charging.
So it looks like it is working but there not enough power. Anyone have any idea on how to get more power going into it?
There are 3 parts to charging.
The power supply need to have a voltage in the acceptable range. Generally not an issue.
The power supply needs to be able to output enough amps. If it is too low, you will often see a slow charging message.
The cable to your phone must have a low enough resistance on the wires supplying power. If the resistance is too high you will get a voltage drop on the wires.
A power supply with higher amp output and/or a lower loss cable on the path from the power supply to the phone are likely the issue.
If your connection is OTG-splitter-another_cable-power_supply, both splitter and another_cable add resistance on the path to power_supply.
Hi all,
Current owner of a P2XL 128GB, running the .025 Nov patch. Everything works as expected, except, when I try to copy some data from my laptop using the USB Type A-C cable.
USB transfers (using a third party type A-C cable) are extremely slow. I mean, it took me well over 15-20minutes to copy 39MB of data in around 25 pictures. Similarly, it took me well over a minute to copy 2 x mp3 songs around 15MB combined. This baffles me...
I have used this same cable with my Nexus 6P for a long time and had no data transfer speed issues and I also used this same cable to do all the unlocking and flashing earlier on the P2XL. Although I believe P2XL has a USB 3.1 spec Type C port, whereas the 6P was USB 2.0 spec.
My old cable (USB 2.0 spec):

New USB 3.1 spec type A-C cable I have just ordered:
https://www.amazon.co.uk/gp/product/B01LXK7CQG/
Any of you experienced slow data transfer speeds or have any suggestions?
Problem resolved by using a different usb cable and PC. There is no problem with the phone.

I know this is gonna be quite a niche scenario but I'm at wit's end here and I wanted to see if there was anyone else out there who is/has struggled with this: I want to use a more power-delivery capable USB-C to USB-C cable to connect my S20+5G (Snapdragon, Verizon if relevant) to my computer (has to be the USB-C port, for various reasons) for the purposes of a USB-tethered internet connection. Has anyone found a cable other than the exact one that comes in the box that's able to consistently (i.e. no random disconnects, no "USB connect/disconnect chime") hold a connection? My entire internet connectivity (due to my location) is dependent on this so that's why the whole "no disconnect" thing is a big deal.
I've tried a multitude of cables that *should* be upgrades to the stock one off of Amazon (from decent manufacturers i.e. Amazon Basics, CableMatters etc.) but even if they deliver power more efficiently or transfer files faster or whatever, the main thing I need out of them is their tethering consistency, which they ALWAYS fall short of compared to the black "came with the phone" 3 ft. cable. These "higher material grade/better quality" cables will always inevitably kill my connection within anywhere from 10 seconds to 5 minutes of the start of connectivity.
The stock cable provides the type of connectivity I need, however I have no idea what the exact specs are for it but I'm fairly certain they aren't optimal; i.e. while my phone is tethered, the battery can't charge faster than the rate at which it's using power to do the tethering, so if I leave it connected long enough, the phone will die even though it's getting "charged" by the computer. For reference I believe the phone's USB-C port is USB 3.2 while my computer's port is USB 3.1 gen 2 and I don't think the stock cable reaches either of these standards. I've tried looking on the Samsung website but only find the exact cable I already have. Is there a better "official" version of this cable available somewhere? Or any non-official ones that are confirmed to hold the connection like the stock one?
Thanks in advance.
As an alternative, have you considered Ethernet tethering? It simplifies both the logistics of charging and maintaining a reliable data connection.
I would if I could but due to the aforementioned complete dependence on my cell data for our internet service, I have to use some...creative workarounds regarding hotspot data limits and unfortunately it can only be done through USB tethering
Interesting. How are you working around hotspot data limits? I'm curious about this, and wonder why you couldn't do something similar for Ethernet.
BTW, I use this with my phone:
Anker 543 USB-C Hub (6-in-1, Slim)
The Anker Advantage: Join the 55 million+ powered by our leading technology. Massive Expansion: Equipped with a Power Delivery input port, an HDMI port, an Ethernet port, a USB-C data port, and 2 USB data ports. Powerful Pass-Through Charging: Connect a 65W wall charger to the Power Delivery...
us.anker.com
It accepts USB PD input and when paired with a Samsung 45W charger and its stock cable, does a great job at quickly charging my phone even when using DeX over HDMI or powering USB hard disks, etc. And the Ethernet link is rock solid. For reference, I am running DUJ on a SM-G986B.
