New Car Tablet --> OTG charge + PowerEvent Manager + Extended screen

Hi there,
I just found this awesome tablet as I planned to exchange my Nexus 7 2013 LTE as car device. I bought Timurs Kernel for this and it works awesome. Unfortunately GSM-calls are not possible with the Nexus.
This flaw is gone with the Huawei tablet. It has a better CPU and Memory performance either. LTE Dual-Sim is also awesome.
Is it possible to port the kernel feature OTG + simultaneously charging combined with a PowerEvent Manager which puts the tablet in Deep Sleep Mode if Power drops and wakes it up when power is available again?
I think there is no chance to attach a 2nd screen via wire, isn't it? I also planned to extend the screen to a 5" Display in my upper car dashboard, but it's very hard to find 5" chrome/miracast displays. Perhaps somebody has a solution for this? I already tried to attach a HDMI chromecast to 5" HDMI Raspberry display, but there are big black stripes on the right and left sides so there are scaling issues I cannot influence.
Which steps would be necessary to get this features working?
Thanks for your thoughts.
Greetings
Schwimmbuxx.

No one interested in car media revolution?

From what I have read about the specs on this device, it has no NFC functionality so no wireless charging android pay etc.
Those are features I never use although I can see NFC charging coming in handy if the micro usb slot gets damaged.
I too am looking at buying one of these to replace my Nexus 7 2nd gen (a hard device to replace) and my now 4 year old ascend y550, I pretty much carry them both all the time since the Nexus is the WiFi version I hot spot my phone to it.
I'm sure there are apps and skins that allow you to set power on/off with usb power, designed for exactly what you are doing.

ASUS ZenScreen GO MB16AP - Will it work with Dex?

https://www.asus.com/us/Monitors/MB16AP/
I'm thinking of getting the Zenscreen Go (when it's available) to work with Note 9's Dex mode since it can double as secondary screen for my laptop too when I need it. However, I'm not sure if it will actually work with the Note 9. Any ideas/comments?

I don't see why it won't work. Be cautious though for a battery drain, since the monitor uses USB-C for its power as well, instead of using (having) its own battery.
I'd recommend for you to get a HP Elite x3 Lap Dock instead if you meant to bring it out for "portability" (15.6 inch is not portable for me at all) if you plan to mainly using it with your phone. Just think of using your N9 as a bonus of getting it work with a laptop.

The MB16AP has its own battery. The big question is when will it become available.

Yea, the screen has it's own battery. I know Dex works using USB C to HDMI, but I'm not sure if USB C to USB C will work with the Zenscreen or not.
I have considered the HP Lapdock but without the phone it is just deadweight. At least the Zenscreen can serve as a second display for my laptop so I'll be getting more utility out of it.

USB C to C will work. I use an HP Elite Lap Dock with a USB C connector..
Regarding HP Lapdock, it is not. If you're using Note 9 with it, your phone will still functions as usual. The deadweight happens if you're using older DeX phone that doesn't support dual screen DeX.

Asus is coming out with a touch version of the MB16AP, but I've searched high and low for the model number and came up with nothing, and who knows when it will come out. In the meantime I ordered the MB16AP on ebay which is the non-touch version with the battery and it should arrive next week. According to the Asus website, it should be compatible with any android phone (version 5.0 or above) and most laptops with Displaylink drivers. So I assume it will work with the Note 9 in Dex mode.

Good to see ya here in the Note 9 forum TS ! :good:

Nice!
Wow i'm sure glad I saw this.... been looking for something like that HP Lapdock. I got the Sentio Superbook and after a year and a half it was quite a let-down. Tech just changes so fast and the user experience was not good. Played around with Dex and it works well for my needs.

Well that external monitor (MB16AP) came in this past week and I've been testing it with the Note 9. First of all, she is a beauty. Works with the Note 9 and DeX without any issues. On the Note 8, I had blackouts and all sorts of issues using either a hdmi or vga monitor. Since then I've upgraded to the Note 9 and the same issues appear but less so. It was somewhat manageable. I figure it may have been the monitors and not the Notes. But when I hooked up the Note 9 to the Zenscreen MB16AP, wow what a difference. Smooth as butter.
The only issue I've encountered is since the Note 9 and the Zenscreen use a single USB-C cable, there is no way to use any usb or usb dongle wireless mouse and keyboard. You are either forced to use the built in Note 9 keyboard and use the touch screen as the mouse. The monitor finally showed up on Amazon and its about $50 more than on ebay due to the shipping. But at least Amazon has a way better return policy that the two outfits on ebay that are selling the model.
I did a somewhat review of the monitor on Amazon.

I was about to get a zenscreen go, before I got an HP X3 Lapdock. I'm rly glad I got it instead, cause I was gonna get the Zenscreen, and a BT keyboard and mouse to mimick a lapdock like miracast.
No need for that nonsense now. If anyone gets an HP lapdock, the only combo I've seen work consistently is the Snapdragon Note 9 + The american Lapdock model which starts with a V. All the other models have various things that don't work. They start with a Y. I'd also avoid getting a refurbished one, as it's not known is they used parts from other models that are not compatible with the Note 9. Just get it new on amazon or ebay. new.

I got the HP Lapdock and boy so glad I did. For my needs it's perfect. Everything works great and the battery lasts a long time.... I ran it over 7 hours yesterday to test. The only thing that doesn't work is left and right clicking on the touchpad do nothing. You have to use gestures.... but I use a mouse anyway.....
Seriously Samsung needs to make their own lapdock for dex.....

I have an Asus MB16AC that I use with my laptop. I tried it the other day, but the monitor would only power on for 1-2 seconds. This evening, I charged the phone to 100% and tried again.
Using the USB-C to USB-C cable to the Note 9, screen mirroring works great, but only lasts for a short time. Playing video makes the monitor power off even faster. Definitely a problem powering the display from the phone.
Switching to Dex mode makes everything go black. I assume that Dex mode takes more power.
I'll order a powered USB3 hub and try again. I can't seem to find a USB-C hub that has USB-C ports, except for one that does PD (Power Delivery).

Have you found a solution for the power? Wouldn't charging the phone with Qi help or USB-C PD is needed? I have not found any adapter allowing out on phone, and in by another USB-C that would send power.

Yes I can place the phone on a wireless charger while using the USB-C cable to send the DEX display to the monitor. But it seems the monitor is taking up more juice than it gets. Thus depleting the battery eventually. You would think that if the Note 9 is supplying the power to the monitor that the monitor would not use the internal battery but it seems that it does. Then if the internal battery goes down to 0, it will not allow Dex to display until the internal battery has at least 5% juice. It baffles me why Asus did not include a splitter of some sort or have the device have another USB-C port for charging.
btw that USB-C 3.1 Gen 2 cable by NekTeck is a suitable replacement for the OEM Asus USB-C cable.

Xperia XZ Premium Charging Issues

Hi All,
I'm hoping someone here can share their opinions.
Recently I've been having charging issues with my XZ Premium. Started a few weeks ago, with the charger plugged in, it would randomly stop and start charging.
Lately it's been getting much worse. I have tried different chargers, cables, adapters etc. The original Sony USB cable plugged into a wall charger, and my laptop. My Dell laptop USB-C (thunderbolt) wall charger, as well as my Dell external battery charger, as well as MicroUSB cables with a USB-C adapter.
Without touching the cables or moving anything, sometimes it'll start or stop charging randomly.
I personally think it's the phone's USB-C connector. I've tried to clean it using a damp wooden toothpick and got some dust out, but it didn't make any difference.
The phone is rooted, and is out of warranty anyways. I also have a lot of security features installed which would make it hard for a tech to troubleshoot (needs passwords etc to be shut down or rebooted) and I store some cryptocurrencies in wallets on my phone.
Is it worth taking it to a tech (I live in Japan, and don't speak much Japanese) or should I be looking at an upgrade? If so, what is the recommended phone from Sony currently? I honestly really like the XZ Premium, so I'm tempted just to buy another one if mine can't be easily fixed.
Thanks!

Bit of an update.
I managed to get my phone to charge using the original Sony USB -> USB-C cable, with an adapter plugged into the thunderbolt port on my laptop. Charging is still incredibly slow though. Also, I noticed when it hit 30% charge, it stopped accepting charge unless the phone is unlocked. If I hit the lock button, the charge light switches off. It switches on again when I unlock it.
*Small edit* It stopped charging again at 31%, despite being unlocked.
Wiggling the cable in the phone socket doesn't seem to effect whether it charges or not, which should rule out the connector in the phone. It has also not registered as a device on my laptop, despite being connected via the USB cable, which would mean it's not specifically a battery issue either, as there's no data connection being made.
So I'm starting to think it's a hardware issue.
I've ordered a new Xperia XZ Premium, because I really do love this phone, and the new XZ2 Premium doesn't seem like much of an upgrade to me apart from the camera, and slightly faster performance. And as much as I'd love to have wireless charging, moving the finger print sensor, and no 3.5mm audio output is a massive dealbreaker for me.

mine died like this, was on charge, started to say charghing/discharghing until he turned off and never came back.. under warranty they changed MoBo/2 stickers/components (??)/ 2 screw and now is back like new

Long term bump.
I bought a new replacement 8142 and have been using that successfully, and I decided to try and fix the charging issues on my old one.
I've just installed a brand new genuine battery, charging port, and power/vol/camera button connections.
The phone booted up fine, but it's STILL not charging at all. Any ideas? Motherboard maybe?

Maybe the flex cable isn't working

have only just started having this issue yesterday, have tried different charger and usbc cable combinations, cant even get my pc to recognise it as a plugged in turned off xzp and it wont turn on only show the battery icon with low level indicator in the red.

I have a similar issue.
When I connect my XZP to the pc using a Rampower cable USB-C to USB (sold as 5Gbps and 5V/3A power, thus an USB3.0 with fast charge of 15W) I suffer of the same issue exposed above: randomly the connection get interrupted.
While, charging the phone, yet with the above-mentioned cable and original Sony charger, I get no problem at all!
NB: I have never tried with the original USB cable...

Common fault with the xzp.
The actual connector from the logic board that the usb c module connects to burns out. Require a new logic board or connector to be replaced/soldered on and new usb c module.

This is good news, because sourcing a mainboard is half the price of the phone, and I've already spent money on a new battery and charging port etc.
My 2nd G8142 phone has just started displaying the same symptoms, and I can't afford a complete replacement.
Can you confirm that this is the part I need? https://www.aliexpress.com/item/4000160901916.html
If so, I'll grab 2, and install into my old phone first to confirm the fix, before then installing one in my newer phone.

Lucky you!
I'm onto my 2nd one, and have had the same charging issues with both.
Both phones have been rooted with a custom ROM, and I use my Dell smart-powerbank to charge them fairly often. So perhaps that is the cause of the early failures on both.

Unfortunately I can't confirm if that is the exact part you need as I don't do repairs. All I can confirm is that my repairer has stated that he has seen XZP's with the same recurring issue with the connector burning out.
My guess is, that is the part as he had to micro solder a new connector to the logicboard.

That's good enough for me! I'll grab a couple of them and see if it fixed my older phone first (because I've already tried the battery and the USB-C socket etc) Will update once I've done the repair.

Hope you can fix that problem and share some experience on this issue. Mine has a similar problem. The difference is that it can be charged to 100% but very slow and randomly stop.

Yep, that's how my issue started too. It'll progressively get worse.
I've just bought a Google Pixel 3 XL as my 2nd XZP has ceased accepting any charge at all. I'll see if these motherboard sockets fix the issues, then keep one and sell one. Otherwise I'll just sell them both off as parts.

I talked to some tech on Alibaba (A Chinese shopping website) and they said it can be fixed by replacing that socket. But the replacement requires professional welding equipment and skills. Or the motherboard can be damaged. That's why I am looking for other people's experience before I take step myself. If you succeed, please update this thread. I think there are more people like me who is looking for successful experience from others. Thank you for your sharing.:good:

convert micro USB to USB C and add a larger battery

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.
**What phone should I buy next?** -- Not sure what device to buy? Ask here!
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...
forum.xda-developers.com
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.

Wireless Charging Mod

First time creating a thread, but I have a OnePlus 8 UW running CRDroid 8.6 on Verizon. I have been loving the phone but am really missing wireless charging(I came from an s20 FE 5G). I found THIS video and am going to be attempting the Mod. And keeping this thread updated. Does anyone have any suggestions or experience in doing this mod or a similar one?

Modification successful.

Was relatively easy, soldered the the vbus+ section of the ribbon cable(4th pin). Phone is now able to wirelessly charge at 5w. Looking into at some point upgarding to higher wattage charging. Let me know if anyone has questions

Definitely something to consider when taking the phone apart anyway (eg replacing broken screen or battery).

I need to swap the USB C board on my 2XL, thank you for posting pictures, I'll give a go at it while it's opened up. Shouldn't be too different from the OP8
