These chinese devices are awesome for their price! I got a chinese Jiayu phone that works nicely. but uh too bad about your sour egg. Best option - return it for full refund or replacement. Other options:
1. contact JXD
http://jxd.hk/
Voice phone: +86 755 8397 3170
[email protected]
[email protected]
2. if the touch screen or physical controls work, then do a 'factory reset' under System Settings and power off and power on. (google it...)
3. if there is physical volume button, then when power is OFF, hold volume UP and power on. or try to hold volume DOWN and power on. hopefully :fingers-crossed: you get a screen like this

. (taken from this blog.) Another way is to hold either volume button and then connect USB cable (still holding volume button). You got golden profit now. :victory: That is recovery mode. You can do a data wipe in there and install the latest firmware from JXD. Choose the right firmware FILE for your model. (google it...)
4. can you remove the battery? if so, remove the battery, disconnect all cables, press power button for 10 seconds, let go of power button, insert battery, and power on
5. you can google and search inside this xda site. "jxd 7800 hardware" or "jxd 7800 touch fix" or something like that. I found "dingoonity" forums and wiki.
good luck & cheers with a beer mate.
*EDIT* -- Here is a youtube video of my JXD device playing an included game "Monster Shooter - Lost Levels" in its stock rom Unfortunately, the touch screen sometimes stops responding to physical touches (my finger). http://www.youtube.com/watch?v=Ju44OWs6G2I

button issue
my cursor on the up and down button son the d pad or joystick make my jxd s7800b jump all over the screen is there a way to fix this sorry im new to forums this is closest post i could find

I found the main chip controlling the analogue sticks on these devices can sometimes be poorly soldered. I had a similar issue and fixed it by reflowing the solder. The analogue control chip can be seen here....

My fix was to resolder the bottom right pin seen here....
https://www.flickr.com/photos/plymouthbiker/22259048902/in/dateposted-friend/
But of course it might be different on yours. So check all connections and chips for poorly soldered points.
Best get a good magnifying glass and look up close to see if any are poorly soldered. If you have the skill to do it without shorting out any of the connections, it's an easy fix. But be careful as you could very easily wreck the device for good with a blob of solder in the wrong place.

Once again, it might be the soldering. Check inside the device. There are a couple of videos on how to dismantle it floating around online. Be careful dismantling it as the ribbon cables are very delicate. once you've broken a ribbon cable its near impossible to replace as parts are rare online. Once broken the only general option is a new device and sell yours for parts. So honestly when I say take care I mean CAREFUL!!!! See the picture links I've just posted for the chip issue that you might be experiencing. Or something closely related.
I found as my device heated up, the expansion of the metal inside created a loose connection where the solder wasn't correctly done on the motherboard. Re-flowing or adding a tiny bit extra solder is the only way to fix any poor connections. (SKILL REQUIRED NOT TO SHORT ANYTHING)
Also while doing this make sure all the ribbon connections and correctly seated when putting the device back together.
Best of luck.

Does anybody else disconnect phone calls accidentally with their chin?

For a while I was doing this almost every call. Now it happens about 50% of the time.
Am I the only one who accidentally disconnects calls with my chin pressing the "End Call" button?
Is there a fix or am I just not used to this phone....?
(I realize that I am opening myself up to some serious smart ass comments)....
Thanks
Clean off the sensor top left of the screen. It automatically turns off the screen when you have the phone at your face. There is also a setting somewhere to control this. Check that it is on.

It happens to me all the time, I've cleaned the sensor many times and it doesn't help. I think its just a design flaw from them putting it behind the mesh for the speaker, this is also why you can't see the led unless your looking straight at the phone. Luckily I don't make a lot of calls because this device wasn't designed to be a phone, it seems like that was just a feature that was tacked on in the last minute because of the horrible proximity sensor, bad call clarity/speakers and mic
Download myLock utilities (free at the market) and enable 'In Call Screen Lock'. It wont solve the prox issue, which seems to be a software flaw, but it will prevent accidental screen touches. Also, make sure the 'back button' option is checked, since the phone does not have a camera or nav key.

Try Settings->Call Settings->Always Use Proximity.
Sometimes orientation can overrule proximity if that's off so holding it between your cheek and shoulder allows the screen to turn on.
I've found that after I connect the call that pressing the power button to turn off the screen prevents all of these issues

I went to Menu=>Settings=>Call=> and don't see anything that lists "Always Use Proximity".
Can you please walk me through this again? I must be missing a step.
Please note that I am rooted and using Das Bamf 1.8 Remix which might be the problem for not having this option available....

The only problem with that is that it comes back on as soon as the sensor no longer senses your face (unless it doesn't senses it when you shut it off or anytime thereafter)

Kinda OT but damn I hate it when I accidentally call somebody and the screen keeps turning on and off and I can't freaking end call!! i especially hate it when it's to somebody random. arg... just wanted to get that out there... Small price to pay for a touch phone i guess.

Most touch phones don't have this problem, at least none of the 3 I had other than the tbolt. I think this is because of the horrible proximity sensor placement, they shouldn't have put mesh over it.

Putting a mesh over it is a very bad idea. I suppose that why they didn't do that. The sensor is under the glass, at the very top, in the "check mark" part of the Verizon logo. Dust can get in through the small crack at the top of the screen, and cause problems - a shot of air will clean it out.

[Q] Problem with touch screen!?

Ok heres my problem.
I have an unlocked atrix running on redpill and this morning i noticed that i have a "dead line" across my screen. About 1 inch down on my screen there is about a centimeter space where the touch does not register. So I downloaded a touch test and it sometimes does not register at all and sometimes it registers even when I'm not touching it.
I also checked and the screen is flat across (no dents/cracks etc...).
Do you think that this is a hardware or a software problem?
And any ideas how to fix it?
Thanks!
Try flashing the pds image. There's a thread about that in General.
I cant find that post i've been looking for an hour and a half, can you help me with a link?
sorry...
Also will reflashing my rom help?
Ah, you asked nicely..
http://forum.xda-developers.com/showthread.php?t=1131649
Try flashing another rom, you never know. Doubt it though..
We have the same problem I think. I missed this thread and started a new one.
After installing Faux's 2.0 enhanced kernal on my CM7, I now have a dead region of my touchscreen which is a little above the middle of the screen, 1/4 inch all the way across (horizontally). I verified this by using the touch test app from the market.
It is also very obvious as scrolling is extremely laggy.
I have already tried wiping my phone with fastboot, performing the PDS fix, and then wiping again in recovery and reinstalling CM7.

You can see the dead space, very frustrating.
I have even tried flashing back to 1.83 using fruitcakes, then downloading the official moto gingerbread update so I am as close to stock as can be other than being unlocked and still no go.
Is this a hardware failure (that others are having too apparently?)

although the OTA update is essentially the same thing, i would say your last glimpse of hope is using rsd lite to flash a gingerbread sbf. (2.3.4 sbf file, just to clarify)
and if that doesn't work, at least your phone will be in a completely stock state to go in for a warranty replacement?
Just flashed it, i'll check back in later

Well I just felt like a fool.
I did absoloutely nothing from yesterday (when I went back to 100% stock, reset phone) to today.
At 1:30, I did the same test with Touch Test and got the same dead zone. By the time I got to ATT for a warranty exchange, the screen worked flawlessly. Other than turning on airplane mode and having an extremely low battery @ 5% I did nothing in that hour.
I'd rather have the problem come back at this point and get a new phone than it work fine until my warranty ends and i'm stuck with a dud.
My dead spot is a little higher... but same thing.
Can you think of anything that happened to the phone that would damage it like this. My wife plays coin dozer (there is a lot of tapping) and the dead spot is around that area.
And wow that's bad luck. Mine was going on and off (more dead then alive). Did yours die again or is it back to normal?
I just want to figure out if this is a software or a hardware problem.
On another note i just flashed redpill v4 and it hasent happened yet... maybe. I can only hope...
Well, my phone fixing it self was only temporary.
After going home and doing nothing to my phone other than charging it, the dead zone is back.
This is a hardware issue for sure, the digitizers seem to be failing after some time.
Get a replacement.
thanks.
more money into this phone...

But what about orange's fix?
http://www.motorola.com/staticfiles...4.4.20_Orange_GB_Upgrade_Release_Notes_GB.htm
"Screen Touch Sensitivity | Fixed touch-screen ghosting and phantom touch events."
Your digitizer connector is cracked.
prove it by pushing on the top left above the glass and use touch test and watch the difference. You need a new digitizer it cost $60 and about 30min to an hour of work.
What's the difference should be? One time touchscreen wasn't reacting but only one time. But how could it prove digitiser problem?

because that's where the digitizer connector is, and pushing on the screen there will cause it to move.
when mine cracked, it caused it to double the effected area when I was to push there.
also, I had made a typo in my previous post.
it's the top left, not top right; i apologize.

I have from 2 to 5 ghost fingers, which a) moving horizontally toward the edges of dead zone, b) located motionless at the edges of the dead zone. What behaviour of screen should be if I press that point on the healthy phone?
Is it what I need to replace?

[Q] Physical buttons stuck, can't turn on tablet

Hello all, I have a G-tablet with a stuck volume and power button. I took apart the tablet and saw that the little metal dimples which get pushed down by the plastic button are stuck flat. Is there any way to fix this?

How old is the gTablet? Could it still be under warranty?
Sent from my gTablet using Tapatalk.
I bought the tablet off craigslist with the button problem already present.
I managed to get the button working a little. But now it seems to be stuck in APX mode where the screen doesn't turn on or anything but my PC recognizes it in APX mode. It will not start on its own. A little googlefu led me to this forum
http://www.slatedroid.com/topic/221...n-gtab-does-not-turn-on-and-stay-in-apx-mode/
I followed the instructions, but when I get to step 2.1 it boots to tap&tap instead of recovery. If I shut down the tablet and turn it back on it goes right back to APX mode again without me pushing any volume buttons.
I'm new to the gtablet scene so if somebody could point me in the right direction to fix my tablet, it would be greatly appreciated.

Thinking out loud...have you tried disconnecting the rocker switch @ the connector to make sure the vol (-) contacts isn't still making contact & forcing the tablet into apx? Disconnectng should make it appear that neither Vol - or + is pressed.
As far as repairing the switch...from appearances, the contacts on the switch looks similar to what Atairi joysticks used to use (on a board vs ribbon/flex cable)...the switches would fail when either the plastic coating over the contact wore through causing the disk to move & not make the correct contact or the adhesive tape covering it would let loose causing faulty/randon contact. I used used to remove the adhesive tape & re-cover the switches with similar adhesive plastic to make them work again. Can't tell from your picture if removing the film is might be possible, but if it is, it's something try...especially it the contact is actually stuck down.

G-Tab no longer under warranty
If you did have a warranty you voided it the minute you opened the tablet. Did you check it really good for any type of sticky substance that might have gotten into the keys? It happens and all it takes is one mi-nute drop from a soda or etc etc etc.
Thank for the replies but I am glad to report that I got the Gtab working properly. I fixed the buttons by removing the plastic and pressing down on the inside center of each cap slightly to bend them back into shape. Seems the last owner was a little overzealous when pushing the buttons and completely flattened 2 of them. I covered them with a piece of clear packing tape and all is well so far.
Also fixed my APX mode problem by following djab's awesome instructions.

IMPORTANT FACT for x10mp/mimmi/u20i

Whenever you use your slide keyboard please slide it carefully and return it carefully. You never knew what will happen when something on the inside broke.
The reason why I'm telling you this is because I have X10mp that is now dead. And can't have any repair/support from Sony Xperia.
Last week Wednesday morning, my LED notification lights worn off. I won't turn on even in FLASHMODE. so I think it's hardware fault. Friday morning, My screen just got flipped just like this

I thought it was a system error so I reboot. Afterwards the screen turned its light but nothing to be displayed. I thought again it was soft bricked so I removed the battery and tried to go to CWMrecovery but then again I was wrong. I Can't use this phone anymore. Later afternoon, I discovered the RIBBON of the slide keyboard was torn into two and can't function. That is why I can't use touchscreen, the hardware buttons on the sliding screen was not working. THIS IS A WARNING.
please be gentle whenever you use your slide keyboard. IT IS NOT A SLIDE KEYBOARD, but rather a SLIDE SCREEN so you can visualize and use your hardware keyboard.
Thank you.
PS: if your notification lights are worn off. DO NOT USE YOUR SLIDE KEYBOARD ANYMORE, or you will eventually suffer the same thing as mine.
I hope this help.

Probably it's the flex that is broken. Happened once with mine, slide the phone's hw keyboard, check at the back of it and you can see a cable thingy, check if it had some damage or if it's been torn apart.
It can be repaired, some repair shops have stock on xperia spare parts.

The cable was called the RIBBON and is a part of the flex. The Sony Xperia support doesn't have any spare for the ribbon of this device and can only be ordered if there are more cases of this in our country. That is why you should carefully use your slide keyboard after having the LED notif lights worn off. But even if you are using it carefully after some minor damage like loss of LED notif lights it could still hasten the breaking and tearing the ribbon apart.

How strange a week or two ago my LED lights stopped working.
I thought it was because I dropped my phone.
And, now whenever I open keyboard I get the same problem with the screen.
Rebooting fixes it, until the next time I open the keyboard again.
It gets worse, now sometimes the screen splits in two when keyboard is not open.
The Touchscreen and screenshots work as normal though, it is just that you do not know where to press anymore, as the phone thinks it is displaying correctly.
How did you get the screenshot? As when I took screenshot it showed as normal
I was startin to hav the same problem... the screen goin floppy.... stopped using keyboard now... hope it saves my phone till i get money to buy next one..
my phone has the same problem, the moment u see a screen like that stop using physical keyboard, its been around 2 months my phone is still working normal, just make sure u dont mess with the physical keyboard and u should be good to go

yep, that's is what I'm planning to do however this is a 2010 phone and if you ask the Sony Xperia service support they can't help you because they doesn't have that Ribbon spare part for our device. And will tell you to wait to have more people who have the same problem so they can order to the Sony Xperia MAIN to have spare parts of this phone to their branch.
Happenened to me
This happened to me, but I relocked the bootloader and used seus to reinstall everything from stock. At sony they fixed it inside the warranty so I didnt had to pay anything

Oh yeah, ribbon that is, it is one with the flex so you need to replace the whole thing if the ribbon is torn apart. Bottom line, be careful with your phones. +1 for this thread.

The cable|ribbon is not functioning anymore for me,
Does anyone know what kind is it in order to replace it
Also, how can I back up my phone contents?
As the phone works, it is just the screen that is blank,
Is there a way to connect phone to PC and use PC to backup my data?
I get an error when I tried: code.google.com/p/androidscreencast/
I got it connected by opening flashtool, and then launching program mentioned above, but I do not see the screen - however I can exlpore files
I am not sure if it is that my phone did not start properly (meaning switched off), or that you have to allow root access in order for app to work.
But, I get error in device list or something like that
The program is real slow, does anyone know of a better one to back up data and view screen?
Anyone knows a way to change screen?
Connect to USB?
Backup phone data?
any help is appreciated
Thanks
XD

the Sony Xperia Store are the one's who know about the hardware of this phone. Go to the Xperia service centre and ask if they can repair it. Lucky if they have that spare and if not that's awful you are going to wait for the spare part order from the Xperia Main.

I tried the CWM recovery but it seems that the hardware buttons are also not working for me. I will try your method later, after I got home.

I used EasyADB to copy the files mmssms.db for sms and contacts2.db for call logs
[ mmssms.db can be found in /data/data/com.providers.telephony/databases ]
EasyADB is nice because it is visual, but you can use adb, what is not nice about EasyADB is that you can only pull one file at a time.
Next, I used this program, yaffs-mmssmsdb-calls-extractor , to save mmssms.db as XML to restore using SMS backup & Restore program, and all sms are now restored:
Download the file from this thread: http://forum.xda-developers.com/showthread.php?t=1585957
For instructions see below thread,
http://forum.xda-developers.com/showthread.php?p=32848249​[ It is not necessarily to merge, you can recover one sms db, too ]
None of the screenshot tools worked, though
But.
I got all my smses back,
Which is what I was after in the first place
I rather use on screen keyboard, I also feel sorry to buy mini pro instead of x10 mini, the keyboard is useless on me, but thank's for the warning, the flexi ribbon on my n95 also like that its go on crack because I slide it rudely, but when I go to nokia they cut it! thats sucks for nokia service
Hi all bro, do you have meet same problem as mine?
My problem are every time I changing battery with AC USB cable it's always auto touch screen and run ..auto open keylock by it safe .but if I press lock it (button near headset button) it's not auto touch and run, but if I unlock screen while changing it'll auto run and auto touch everything.
I try take off changing USB it run normal and if I used it to changer with USB via Connect to PC it normal.
It's has problem only with changing.

Good luck...

G5 power button stops working. Fingerprint scanner stops& disappears in settings

Power button / fingerprint scanner just stopped working on my LG G5 yesterday.
Don't know if it's related or not, but it seemed like I had just wiped the phone clean with a Wet-Nap just prior to the button failure.
Weird, because I've been using Wet-Naps to frequently clean all of my phones for years,
and never had an issue before. I attached a pic of a Wet-Nap for reference below.
Also, when I go in to SETTINGS and search FINGERPRINT, nothing comes up in the SETTINGS for adding or removing fingerprints.

As of this morning:
-the "fingerprint" option has returned to my settings
-the fingerprint scanner will unlock and turn on the phone again after going through the setup process again
- the power button will NOT turn OFF the phone's screen anymore
Anyone else having similar issues ???
Any explanations ????
(my LG G5 is 100% stock and unmodified)
same issue here, factory data reset still not working. Support apparently has not experienced this yet
Same here. Fingerprint unlock still works but zero life in the button itself. Resorting to double tap to wake/sleep, but pretty irritating.
I have a little dent near the button, maybe I dropped it, not sure...
I just got this problem today after tmobile pushed the latest software to my phone a couple of days ago.
Had this happen to me today. First g5 says unable to use fingerprint, if this persists, restart phone. It did, and I did, to no avail. Then the option was gone from settings, power button worked to wake, but no scan, and had to use pattern. Pulled battery for ten mins, same. Cleared all caches, same. Then when I frankly went to resort to a factory reset I was told I had 27% battery and needed at least 30% to reset. So I swapped batteries to my spare and boom, all was working, and has been for about twenty hours now. I put my old battery in my phone and the problem was back, swapped back, back to perfect working order. I have two spare batteries for a totally of three. 2 work fine, and the other brings back the problem. I trashed it. How a battery can correlate to this, I'm not sure, but it worked for me...
Omg same thing. Ever since t mobile put a update my fingerprint was not working. Then it wont show up in the settings. Now fingerprint showed up and i fixed it. Now power button doesn't work and I can't take screen shots
Same here on my H850.
I also cleaned my phone by using some wet naps and after a couple of days the button did not recognize every click but still had some live.
Now the button is completely unresponsive. But the finger print scanner is working flawless.
If this is firmware related, the button should still work in TWRP while it might be broken on the real system, right
BTW did someone else fix this by changing the battery beside the one who post this solution ^^ ? And did someone try to turn on the phone when it's powered off? Just in case, does this phone start while charging or connected to the Computer ?
Kind regards from Germany

Have you had any issues since? I'm trying to decide whether I should invest in a new battery

That is a link to how to turn it on without the power button.
The same problem occurred to my G5. Everything was working fine last night, but when I woke up the power button and the fingerprint scanner are not working. The options for the fingerprint lock are also gone in settings. Does this problem go away on its own? What were your solutions to it?
Hey !
What i tried to do is to replace the button myself.
Piece part is easy to find on the internet, and, with the correct set tools, the phone isn't very hard to open.
However, if replacing the button makes the power button working again, it didn't bring the fingerprint sensor to life (No't the hardware Sensor, and no't the settings menu option)
See I have the same problem just woke up and it stopped working only mine still does the fingerprint and will still wake when pushed but won't shut off when pushed, not loose and hasn't been dropped or gotten wet. Happened shortly after an update, any idea how to fix it?
guys how to enable double tap to sleep?
Also am not surprised you got broken power buttons, I already noticed on my G5 it doesnt feel well made and liable to break.
can you guys tell the production date?
6xxk?
i got a g5. i'm aware because someone i know bought g5 and it's power button died in 2 months. and came back to life with no reason lol
i wont even press that button... i think lg will start producing good phones(built q) in lg g7
Try the app "Wave to Unlock" it uses the proximity sensor to lock/unlock the phone.
Works like a charm, if you tune the app well.

That feature existed since Marshmallow

You should not have to enable double tap to sleep already should work.

I know, I never said it's something you enable.
My power button also died, but it was pretty easy to fix. I just took apart the phone and cleaned the contacts with rubbing alcohol. It seems to be a design flaw where the pressure connections between the back panel and the mainboard are not solid enough.
The entire procedure took less than 10 minutes. Remove sim tray, remove battery, remove the 2 screws you find. Slip an old credit card between the outside of the case and the inside, and lift the two pieces apart. See the teardown on iFixit for better instructions.
I am seeing the same issue as of recently. The fingerprint is working fairly consistently, but the power button is not working to turn the screen off or to turn the phone off or onto airplane mode. The phone is still fairly new and has not been dropped or dented, nor has it gotten wet or been wiped down.
Anybody find a fix yet?...
