I want to turn on on my galaxy tab over a microcontroller but I don't know how to do that. There is this REMOTE_SENSE pin. Is it possible to use it for turning the device on? Or what about these serial interfaces? Any chance here?
I hope somebody knows if this is possible...
I'm not sure if there is a pin that you can use to turn it on but I do know that the tab will boot if you connect the charger momentarily and then disconnect it. I'd research the charging pin configuration and see if you can use this to make it boot; you may need to use a relay or something since a microcontroller I/O pin probably can't provide enough current to trick the device into thinking it is being charged.

Thanks Coffeebeans!!! Very nice find. You were right. Fast on/off will make the tab booting.
This should be no problem for me to simulate this on boot.
thx
Hello people!
I have a HTC EVO 3D GSM (signature for specifics, for what it's worth - I doubt it matters for the thing I'm about to explain, anyway).
I know this post is very long, but please allow 5-10 minutes of your time to go through this.
Charger : original HTC charger (1A output).
Cables : two BlackBerry microUSB cables, one is 2 inches shorter than the other. The HTC one broke after two weeks of usage, these BlackBerry ones stand up for the fight even after 6 months of abusing.
Extension cord : HAMA. USB 2.0, maximum speed 480 Mbit/s (that's what it says on the box). "Additional shielding for a good reduction of electromagnetic interference" -> so it's not double shielded (in case that matters at all). It's gray (for what it's worth). 1.8 meters long.
Battery Monitor Widget (BMW) may not show power consumption accurate while deep sleep, but it works fine when the phone is used and, THANK GOD, when CHARGING. So, with that app, I monitored the input current...
So... here's my little personal test.
Battery was at ~81%, so the input current wasn't varying because of the battery level, but because of the (****ty) cable(s). Throughout the test, the battery level got up a bit, but I tried to keep it steady at ~81-82 at the beginning of each test.
CPU @ 192 MHz - 1.51 GHz, Interactive governor. No undervolting, so the table ranges from 800mV (192 MHz) to 1175mV (1.51 GHz). Nothing changes, anyway, even if I undervolt it -75mV, so the voltage has nothing to do with it (maybe during * tests, it could mean a difference of a few miliamps, but it's not a viable solution).
Charging tests # - Wi-Fi off, Data off, Screen on Auto, off until I wake it and check the current with BMW.
Charging #1 : just with the BlackBerry cable, no extension cord. 1 minute after plug in : +800mA. 2 minutes after that : +789mA. It went up to 82%, so I discharged it to 81% and carried on with the next test.
Charging #2 : BlackBerry cable + the HAMA extension cord. 1 minute after plug in : +489mA. 2 minutes after that : +485mA. Notice that the input current was almost sliced in half.
Charging tests * - Wi-Fi on (signal ~80%), Data off, Screen on lowest brightness. Playing Star Legends (basically, it's opened, I'm not touching anything, any graphics that are going on there are hardly intense, nothing GPU-hunry is going on, so it's just sitting there). Media volume = 1.
Charging *1 : just with the BlackBerry cable, no extension cord. 1 minute after plug in : +413mA. 2 minutes after that : +471mA.
I couldn't resist and entered a PvP, so intense graphics were somewhat there, also touch points and all that... The current input was around +312mA.
Charging *1 : BlackBerry cable + the HAMA extension cord. 1 minute after plug in : -11mA. Notice it's discharging, but at a slow rate. 2 minutes after that : +31mA. So it started to actually draw some current from the charger, so I let it that way for another 2 minutes, and it's got to -5mA again. So definetly no charging here .
Normally, without charging, the consumption would be of about -513mA... -622mA... Same conditions : Wi-Fi on (~80% signal), Media volume on 1, lowest screen brightness, player just sitting there (in Star Legends).
I did tests with Asphalt 6 (no Wi-Fi, no active Internet connection), too. Same consumption... Same sh*t... I was thinking the Internet connection is what kills the incoming current the most (it turns out it hardly is).
So... Has anyone ever experienced something similar?! I really need an extension cord, lol.
----------------------------------------------------------------------------------------------------------------
I was wondering if a more powerful charger would solve this, but after reading THIS, I think there are hardly any chances...
I had another HAMA extension cord before. White, with double shielding, same lenght (1.8 meters)... Same current readings... I brought that one back to the store to get my $7 back, and here I am, 1 week later, having another one, in hope that the previous one was broken and this one is not. Haha...
So it's not the cord itself (bad company, lol), but the fact that there just is another connection the current has to go through...?!
I wonder too if part of the issue is using non-OEM cables, as that seems to cause problems sometimes for people in various ways, including not being able to do USB transfers.

Thanks but... This isn't an EVO 3D-related issue only... It's a widespread thing, I believe. That's why I posted it in a section where more people would see it... Otherwise I would have created the thread here directly...

Now that this thread is no longer in the intended section... It's useless. Thanks.
Please lock it.
It's very clear the problem is your USB extension cable. Those are known to have problems passing current AND data. My work computer has a 3 foot usb extension cable so I can plug a flash drive in without crawling under my desk. It works fine with flash drives, but will not power my small hard drive that only takes 400ma of current to run.

usb 2.0 significantly looses power after 6 feet if you want what you are doing to work then buy a powered extender problem solved
Make sure your using a heavy extension cord i use a 6ft 12 gague cord with no problem. Charges 700-900 ma all day with htc cable.

Guess I'll have to look after those. Thought HAMA would do... They're advertising it to be "that" good on the box... I'll return the little box, get my $5 back...
Thank you for your responses!

I assume you meant 6ft 12 gauge, not gague. The one I found (see link below) has a gauge of 24 AWG power line (guess that's good? ).
What do you say about THIS one? (Just ignore all the Romanian texts, there's English too ).
Hey, guys... Could you please tell me your opinion about this USB cable? By the specs, it looks good...
USB 3.0 works with 2.0, so that wouldn't be a problem, I guess...
i was wondering if anyone else might be having this problem.
when i connect the phone it shows up and is accessible in adb but after a few seconds, between 15 and 20, the device goes offline but still shows up as attached.
if anyone has any suggestions for diagnosing this problem or experience with it please share.
thank you
ok well the 10th reboot and 5th port change seems to made the phone happy. stable for 10 minutes so far.
it seems to like a shorter cable or to be plugged directly into the motherboard usb port instead of the front panel ports.
Hello,
on Christmas I buy Sony Xperia XZ1 - G8342 , but I in the box was only Sony UCB-20 cable (USB-C 2.0). So ... I buy cheap USB-C 3.1 cable , but it so bad , that if I plug it wrong way the transfer speed were 1MB/s , so like 2hours ago I got Sony UCB-30 (UCB-C 3.1Gen2 10Gbps) , but still got only 425mbps on USB tethering with UCB-30 cable . Even phone have only 35MB/s write speed , but the read speed are probably capped by USB2.0 because it go 60MB/s read speed. Does someone else have this problem ?
+ other thing with my motherboard , I can connect and transfer files only on my USB 3.1Gen2 ASMedia port , all other ports just connect disconnect the phone doesn't matter if USB 3.0 USB 3.1gen1 , other devices like WD Elements (USB 3.0 external HDD) work as they should (+120MB/s transfer speed etc)
Googled about this more than +5hours , and even installed clean Win10 (1809) just for this, installed Xperia_XZ1_driver (link below) , in Xperia Companion I did Software repair , of course I did try other PCs too
https://developer.sony.com/file/download/xperia-xz1-driver-2/
only thread who talk about USB 3.1 is this one :
https://forum.xda-developers.com/xperia-xz1/help/remote-ndis-usb-tethering-speed-usb-3-1-t3690554
Specs :
Sony Xperia XZ1 - G8342 - 47.2.A.6.30
Win10 1709 & Win 10 1809
Gigabyte X470 AORUS ULTRA GAMING (rev. 1.0) , BIOS F6 2019/01/25
EDIT 2021.06.06 :
Provider in my country had promotion: "unlitimited free LTE internet for one day", and I have still ADSL, so I use it,
but my cable wasn't the best, because it drop tethering all the time, with my all the time used USB 3.0 cable. I was like ... last time this one day free internet worked for 8+ hours without problem, so I used my Sony UCB-20 cable, and after that I had stable connection whole day.
If you want to try how good is the cable try USB Tethering :
To try if your USB 3.x cable is really 3.x and not 2.0, connect your phone with your PC and turn on USB Tethering, in setting you will see speed connection of 851.9 Mbps, if it is only USB 2.0 connection you will see connection speed of 425.9 Mbps. It is only connection between Phone<=>PC, not your Internet connection speed
For testing quality of cable, or if the pins are worn out try this :
When you are on USB Tethering internet connection, press Winkey+R and write this command " ping google.com -t " , without using much data, you can see how many packet drops you have, with good connection you should have like 1-3packet drop a day
It should be faster.
So you tired different cables and different computers (all usb 3?) Did you get the speed readings from the network settings?
What usb modes did you check?
Is the phones socket clean?
[RESOLVED]
So in the end , even I did buy "Sony UCB-30" it was fake/defective cable (one side of the cable did have Sony Logo , other side didn't)
after 3. cable I have USB 3.0 speed with my Sony XZ1
first company is PremiumCord , which is very terrible company , all cables suck made by them
the second was probably factory discarded defective cable , which some companies buy and sell , because of greed ...

Hi,
TL;DR my phone is dead, my phone isn't charging, here is a little bit of detail since it's last charge.
1. B% 39 - Charged mine a bit to 39%, this was in the morning.
2. B% 33 - Attempted to connect it to an external display. Didn't even recognise it, it works as my laptop is receiving charge and is seen on there.
3. B% 10 - Tried many chargers, including original wall plug and cable, not charging. I tried connecting my phone and the original cable to my laptop, said it was requesting too much power. Laptop says power surge on the usb port.
4. B% X - Phone dead, now desperate. Back up was a few days ago but i changed a lot.
Please help, updates will be added below:
(Update 1)
Edit, not working at all, left Huawei and moved to Redmi
