Few minor but annoying things

1) Does anyone know what can I do to be able to use any buttons with a Jasjar closed?
I tend to use it as a MP3 player and I'm using XDA II headset with two buttons which I assign to "pause" and "next track", but unfortunately as soon as I close the JJ (with the screen hidden) they stop to work, even without pressing the power off button.
I don't want to use screen protector coz one of the reasons why I bought it is beatiful display so I would like to keep it closed when I carry it in my pocket.
2) Is the synchronisation working only with the USB 2.0 ports? I'm using the USB Hub which unfortunately is only 1.0 and the PC doesn't recognize JJ, I have to connect it directly to USB 2.0 port to make it visible.
3) Is there any way to remove the line above the two function buttons at the bottom of the screen? I mean the one with icons for screen rotation and wireless manager. I never use these icons anyway and I'd rather have more room for the appointments.
Thanks in advance for all help! :wink:

How to stop phone turning off when USB is connected?

I got my galaxcy yesterday and have a problem when the phone is connected to the PC with USB. The screen keeps turning off after 30 seconds and the connection is broken. Is there a way to keep the screen or connection alive until I disconnect the USB cable?

Go into Applications, Development, and set it to keep screen on while connected to power source (or alternately make the screen timeout longer, it goes up to half an hour in Display settings).

Thank you, that worked.

[Q] G1 Car Phone Power on USB

I'm building a simple G1 based solution to track my car using the phone's GPS capabilities.
Basically, the desired solution is that the G1 is wired to the car's accessory power system, and when the car is either started or the key is in the accessory position, the phone will be turned on and report its GPS coordinates occasionally.
I have most of the pieces put together for this... A G1 running cyanogenmod 6.1, a hacked up car charger that I can wire directly to car power, and some preliminary test software.
My problem, is that the phone doesn't automatically power up when plugged in. The problem scenario will be something like:
1) Car turns off
2) Phone goes on battery power.
3) I go on vacation and don't drive the car for two weeks.
4) Phone battery dies at some point.
5) Restart the car.
6) Battery starts charging. Phone never turns on. GPS tracking does not resume.
Any ideas on how to work around number 6? I don't supposed there's a firmware mod or something that changes the power-on behavior?
All ideas (even crazy mechanical ones) are welcome.

This is just an idea, so don't read too far into this...
How willing are you to modify the phone?
Here's why:
Ok...When you push the power button, it completes a circuit, causing the phone to power on.
1. Mod the phone, with a relay. This relay would switch one time per power cycle. Allowing for a quick one time completion of the power circuit, forcing the phone to power on when the car does. ...Turn the car off, the relay clicks again, turning the phone off. (Set the power button to turn off when pressed instead of sleep.) ..You could also go as far as to use a software mod to have the phone start a macro when the power button is pushed. This macro saves current state of whatever is running, then powers off. there are paid apps to do this BTW.
2. Set this program you will be using to autostart with the phone.
Viola... Problem solved. ...Easier said than done, I know. Just a thought though. Great idea BTW.

G1 Car Phone Power
Easer said than done.
Is a bit of an understatement.
even takeing off the case and seting up a relay onto the on/off button would not be a very neat solution. As a ciruit connected simply to the on/off button would not know the current state of the phone .
Is it off yet? is it on yet.
And simply checking the charging current would not reliably tell you if the phone is on or off . So you would need to find a power pin on the processor tracks that is held to vcc when the phone is on.
Hope this gives you some ideas.

This turned out to be an interesting project (and a PITA). I'll post pics at some point before I permanently deploy.
What I ended up doing was sort of splitting the difference on the relay issue.
As you suggested, I ultimately could not find anything approaching a software/firmware based solution for power-up on charger connect. To solve this problem, I took the phone apart until I got to the front button panel, and soldered small leads to the two sides of the power switch.
This was a particularly harrowing solder job, because the power switch conductors are actually tiny copper plates sealed into a flexible film. To get at them you have to partially dissect the film, remove the top half of the power's membrane switch, and then solder to the tiny plates without melting the film.
Anyway, once the leads were in place, I reassembled the phone. This was also a slight PITA because the front panel is engineered with no free space and now has to accommodate the new leads coming off the power switch.
After reassembly, I found a cheap timed relay circuit board that trips its relay for a variable length of seconds or minutes, and then goes dormant until being de-energized and then re-energized. I wired the relay to the power leads in parallel with a momentary power switch, wired the relay circuit to car power, set the circuit to 10 seconds, and it worked perfectly. Phone turns on every time.
It's not entirely deterministic, but I'm OK with it. Realistically, when has your phone ever NOT turned on when you held down the power button for 10 seconds?
The other half of the project was to catch the charger disconnect (car turning off) and power down. This was far simpler to implement, as the phone is rooted and I have access to everything I need to shut off.
I created a simple BroadcastReceiver that catches ACTION_POWER_DISCONNECTED and runs this little block of code to turn off the device:
Code:
Process proc = Runtime.getRuntime().exec("su -");
java.io.OutputStream os = proc.getOutputStream();
os.write("reboot -p\n".getBytes());
os.flush();
os.close();
I haven't tested it extensively, but it seems to work as expected every time.
I could make this a little more deterministic by creating a service that watches the charger connected state and initiates a shutdown when it notices a state change to "disconnected," but it's not clear to me that a BroadcastReceiver is any more unreliable than a service that can be pushed out of memory.
I loaded it all up into a little plastic case, and it seems to work pretty well, so far.

Note 4 no power-on after opening

My Note 4 (N910F) wasn't recording media-audio, none of the voice-call apps worked, recording video or audio didn't record anything. Regular calls on the cell network worked flawless though!
So i decided to open it up and see if maybe anything got wet. I cleaned some dust carefully with pressured air and some soft cotton buds for the contact points and put it back together again.
Now the device won't start at all anymore.
I can connect the charger on USB and it does show that it's charging and almost full and i can push the menu button to get that screen again after it turns black.
I can connect it to a PC, it detects the device as well.
What i can not do however is turn it on with the power button. Nor does it show the charging screen when i press it shortly.
I suspected there's something off with the switch so i measured it.
Pin 3 and 4 are shorted by default (vibrator motor i assume). Pin 1 and 2 short when i push the button. So that seems to be as it is supposed to be as well.
I have no idea why it doesn't start or get the power-on signal.
Is there anything else i can measure or somehow i can force the device to start by connecting points on the back of the mainboard?
Any help would be appreciated.

[Help] Broken Screen for my PH-1

The screen is broken. I cannot see anything and cannot unlock the phone.
But I am sure the phone is work because I can still using the web Whatsapp.
Is there any adapter without app installing can output the screen to TV?
Or any dock / adapter support hdmi out (without app installation / usb debug mode enable) and mouse control so that I can backup the data?
I installed AnyDesk in my PH-1 but it only available when the app is open
Howerver, I cannot unlock the phone to open it

So you have black screen of death (BSD) ie software or you think it's actually physically broken eg screen cable disconnected etc?
Anyhow, have you tried forced reboot (Press and hold the Volume Down and the Power keys together for up to 10 seconds ) which will perform the simulated battery disconnect, also try without SIM card as this used to sometimes fix black screen issue on other phones.
You could try using a mouse with a USB OTG adapter with talkback turned on (long press both volume keys at the same time for 3 seconds, you might have to try a few times) ... then you should be able unlock phone & turn on anydesk. ,(Basically you move around by swipe right or left, or click mouse pointer once to move that area & once you hear the option you want then double click anywhere to select) (I'm assuming the otg mouse will still work with talkback on)
[if it's software issue then maybe screen will work in recovery ... but if screen doesn't work you'll have to be very very careful not to select a wrong option!]

You can use most any USB-C to HDMI adapter. If it works for a MacBook Pro with USB-C it will probably work for you.
No special software needed. It automatically mirrors the screen.

Thanks for your reply. I am sure my phone is working because I can capture the screenshot and wait for auto upload to google photo.
OTG Mouse and keyboard is working, but no screen so I cannot unlock the phone.

so did talkback work with mouse pointer? You don't need to see screen it will "talk" to you so you know where you are on screen. Though using the HDMI adapter would be easier

No. Cannot active the talkback function by press Vol Up & Down

I tried to connect Travel Inspira usb-c => hdmi adapter with my broken PH-1 or new PH-1 (updated to Android P version). Both of them no signal show on TV / Monitor.
The PD power supply is necessary? Any setting should I set in PH-1?

It worked with mine but maybe I changed the settings, as shown in screenshot, when I was messing with using the accessibility settings with an automation app, I can't remember what the default was now. Sorry.
Hope you get it working with usb adaptor.

[Update]
My broken's PH-1 does not work but OK for the newest PH-1
I get another adapter which is for Nintendo Switch use and it is work
However the screen is too narrow.
I guess it is because my screen is broken, the resolution goes wrong. (width of resolution was set to 130px)
By adjust the font text to smallest and go in "Developer Option", it is more better by changing the width of resolution to 400px
But it still have a navigation bar at the right hand side of the screen
