Beginning to think the Sensations Issues, WIFI, SCREEN ETC. Are from Grounding.

The phone has such a ground issue that its causing all this, screen issue seems ground issue, wifi, ground, unlock screen, ground.
There is something completely wrong with the way this is grounded causing all the issues, hell even the charger issues could be because of that. I think they need to redesign this thing. I know some claim to have good ones, but Ive had 3 so far with the same issues. I just dont know what to do anymore. Damn g2x wasnt so bad after all.

Any more mad cap theories??

No issues here. Maybe there is a problem with the batch you have been replacing your devices from. No need to redesign the phone.

Not seen any issues with mine, 100% fine.. must be a bad batch or certain firmware revision. O2 UK firmware and phone fine.

Hello guys,new guy here.
There may be a ground issue with the user,not the phone.
Bear with me:
I used to have a good buddy that could never wear a wrist watch for mare than a week.
After that,they died.
It didn't matter how expensive a watch he bought...they all died.
In this case,there could very well be a static buildup coming from the user's body.
Clothes,diet,etc. can affect body chemistry.
If it acts up again,try touching the backside of the phone to a water faucet for a few seconds.
See if grounding out the case helps.

No issues with mine whatsoever.....
Keep in mind before these blanket statements are made, that most owners do not have all the issues you might have. It's by no means the norm. As others mentioned, you may simply have a bad device....or bad app, SD card.
The vast MAJORITY of owners have no such problems....it gets WAY blown out of scale on these and other forums. It would be better to title your thread "I have grounding issues"...
Also, as always, anyone with major issues needs to make sure they still have said issues after a factory reset with nothing installed, no 3rd party apps, no SD card etc. If ya still have issues after that....ya got a defective device.
The vast majority of Sensations are fine....let's keep it real.

We get it....you're having problems with your device....You don't need to start a new thread everyday....I'm sure this could have went into one of your MANY OTHER THREADS YOU'VE ALREADY MADE. As for your "grounding issue", the same thing was said about the nexus one and the EVO....and in the end NEITHER OF THEM HAD A GROUNDING PROBLEM. Just as this phone DOES NOT have a grounding issue either. That being said, if you're having so many problems, return your phone, and go back to your G2X. There really is no reason for a grown man to be whining so incessantly. You have already started several threads about your many problems...post in those....No need to keep creating new threads every time you feel like complaining.
PS
As the previous posters have stated, no I don't have a problem either.

I've got a TMo US Sensation, and it's great. The only "problems" i've noticed is the rare sense lag, but it always clears up in a matter of seconds. And the battery life is amazing compared to my Evo (i can go 2-2.5 days on a charge, same usage level would drain my evo in 10ish hours). While I eagerly await s-off and persistent root, I think this is a very good phone especially so recent after release.

This is your 2nd or 3rd thread that you have made to complain about something. Thread closed, start another thread complaining and I am going to consider infractions.

Replaced Digitizer, now No Internet Connection in status bar

Like the title says, I replaced the digitizer, but now my phone either isn't recognizing my SIM card, or somehow the antenna isn't working. I can connect to my home wifi network, I have full audio, full capacitive buttons and vibration....but signal bar just shows empty (i'm using CM10).
I've put my SIM into my other phone, everything works fine. I've checked all of the connectors on the motherboard, everything is connected and nothing is loose or pinched anywhere. Can someone give me a layout of which connections control what?
thanks.

Remember that there's actually two different antennas. My suggestion would be to recheck each connection and make sure there's a solid click when you connect it

the top connector came off the wire when I snapped it from the motherboard. I crimped the wire back in place but maybe I sould solder.

Crimp should work if the center pin is still making contact with the wire. Soldering shouldn't hurt anything that I can think of

Update, I've purchased a replacement micro-coax cable, that fits correctly, but still have no signal coming to my phone for whatever reason. Any ideas, maybe getting a crappy g2x for parts and using it's cable?

Yup, not too sure what's happening. I literally did NOTHING else to the phone except accidentally rip off the connection on the lower end of the phone. I still get Wifi, so I know nothing internally is broken. I need to call tmo on the off chance this phone got locked due to previous owner payment or reported lost or stolen. It was an LG branded, g2x, though, which doesn't get sold throught tmo.

The LG brand could mean that the digitizer was previously replaced. It sounds like a very peculiar situation you are in. Replacement parts idea is probably best if you have looked over everything very carefully and can't visually find anything wrong. Did you use a hair dryer or other heat source to get the digitizer off? Perhaps the radio portion received to much heat and fried. That the only thing I can think of.

When I first did the repair, I ripped the ribbon from mother board to digitizer, not realizing it was there in the first place. The screen separated from the digitizer pretty easily, no heat required.
The new piece I ordered had the digitizer and outside bezel all attached as one piece, which would normally be two pieces. While constructing everything, I forgot that little rubber/plastic piece that fits near the front facing camera, so I detached the mother board connections, then went down to the antenna area and disconnected the micro coax and the connector slipped off the cable altogether. I put the exposed wire back into the connector, restarted the phone, and there has been no signal ever sense.
The last thing I'm going to try is getting an OEM micro coax from either a P990 or P999. I feel kind of stupid for worrying about this, since it's an old phone with limited development at the moment, plus I have another phone already. But since I bought an entirely new shell, I want to fix this damn thing and probably just sell it.

Canadian G2X/P999 are branded LG and are known as Optimus 2X even though they are not the P990 Optimus 2X which is/was also sold in Canada, each model sold by different service providers operating on different cell radio bands. At a point, T-Mobile was supplying LG branded G2X/P999 phones as replacements. You probably have one of those or, if you bought it from someone in Canada or who was in Canada that would also explain why yours is branded LG.
If you shorted the antenna cable's internal wire to its shield that would short-circuit the cell radio's output which may have damaged the hardware if the phone transmitted while there was a short-circuit.

I think what I need to do, if i wanted to keep this phone, is the buy a crappy g2x and use it's internal motherboard with antenna and coax cable.
Does anyone know what the board is called at the bottom of the phone, near the charging port? It's where one end of the micro coax cable connects. The other end is near the middle of the phone, on the main mother board.
I'm wondering since the board at the bottom had the problem, if I were to replace that.

Here's the repair manual:
http://www.scribd.com/doc/84937521/70/EXPLODED-VIEW

There is a way to test the cell phone radio to determine if it works but it involves installing some Qualcomm software, QPST and QXDM, which are professional tools for monitoring, testing and modifying the phone's Qualcomm cell radio characteristics. My post about how to fix the P999 IMEI has the download links and instructions for setting QPST up: http://forum.xda-developers.com/showthread.php?t=1942417 I'll find the QXDM link and installation instructions and post it in this thread too.

I've written up a procedure to determine if a phone's cell radio is working.
http://forum.xda-developers.com/showpost.php?p=33779273&postcount=1

Finally fixed the damn thing, adjusted the length on either side of the mico coax, the cable isn't being pinched anymore so it works fine. I have a slight problem, though, I have some bright light bleeding from the middle left, and top right of the screen. Maybe because the LED isn't seated flush against the digitizer? Is that what would cause this?
It's minimal, and I don't want to take it apart, but still curious.

Around the screen edge there should be attached to the digitizer a thin foam gasket. If it is missing a piece of the thin foam or if it somehow got disturbed or is not there it most likely is where the bleed is comming from.

[Q] Oven QuickFix – Will it work for Nexus S?

Hello.
So it came. My Nexus S betrayed me. I started getting random "inabilities" to boot my phone. It was rather not booting than booting. The phone was booting like 1 out of 10 times (stuck at Google Logo). Suddenly I found out that applying pressure to the back of the phone (to the SIM card slot area) while pressing the power button solves the issue. At least temporarily.
The conclusion I came to is the following: Given this information (applying pressure) I came to the conclusion, that the soldered-on storage chip is not so soldered-on.
What about this: If oven-baking our laptops can repair them, is it possible to fix my Nexus as well? That is the question for you, guys! Will it take the heat? Can some components fall off the board when heated? Or get burn? If so, can I apply heat directly on that damn chip? That is the metaquestion!
Thanks in advance!

How can you fix a laptop by putting it in the oven dude ? Are you serious ? Ive never heard of that. Ever.
And i can't encourage you that this is a good idea cus it doesn't sound good.

I would rather use a proper heatgun and try to heat the place little bit while isolating rest of the "working" parts.
But honest advice, spare yourself the trouble of disasembling everything and start saving for new phone :/

I found out that my coleague has a heatgun and his friend even has a machine for this (reballing stuff I would guess).
It is, however, good to know, that I'm not lost once I find out I'm out of RMA period. I *THINK* my phone does does have a valid warranty BUT I'm not quite sure I can find my papers and get to the store soon enough. It's indeed good to have a backup…

Go for the heatgun if possible. A lot of the parts on phone are extremely heat sensitive unlike larger hardware and you would likely end up damaging something else rather than just fixing the storage. Have put back to life quite a few devices using a heatgun and proper shielding, mainly xbox 360, video cards and other random peripherals.
Still would save for a new phone though, because it's likely it might die completely on you in the close future.

[Q] Hardware Radio Issues with Nexus 5

I got a Nexus 5 off a friend for a decent price because he dropped it and bent it up a bit. After giving it a quick look, the only thing that seemed damaged was the black little coax wire that connects the main board to the board on the bottom (Assuming it goes to the antenna), The end simply got bent off. This was an easy fix, replace the cable no worries. The real problem is when I went to go test the phone after I fixed the cable, it doesn't get any cellular signal (Wifi/BT still works), draws a crazy amount of power and the 'Qualcomm WTR1605L' chip specifically gets extremely hot, to the point of overheating in like 30 mins. Rather than tossing a bunch of money into replacement components (or getting another nexus 5 with a bad screen or something) I'd prefer to narrow down the problem to one specific component. This leads to my question:
Does anybody have any ideas to how I can further troubleshoot and diagnose this problem, or knows what the problem exactly is?
I have tried a few things, like if I flash the LG G2 radio (A trick I learned I could do with my Nexus 4/LGOG, after backing up my EFS just in case), Wifi and Bluetooth still work while Cellular, GPS and most of the other sensors do not. This stops the big power draw and overheating issue, but doesn't really do anything to further identify the problem component. I noticed that the modem image could be mounted as vfat and you can mess around with the various parts of the image. I don't know which files do what, so I have thus far left it alone.
I know this seems like an odd question to ask here, half the time I see responses like "Send it into Google/LG and have them fix it for you" but that isn't really applicable in my situation
Also, I know that my SIM is good, it works in my Nexus 4, I know that my ROM isn't a issue, because I have multirom installed and tried many different roms. The Radio image shouldn't be an issue because I had updated the phone from 4.4 to 4.4.4/L Preview since I got it (Using the google images and flashall script). IMEI/Whatever the ESN equivalent shouldn't be bad, my friend had been using it before he dropped it.
Thanks in advanced for any ideas, and sorry for the long and comprehensive almost to a fault thread.

Dropping a phone can sometimes cause invisible damage (like BGA solder joints failing). Visual inspection can only tell you so much.

I used to build small electronic projects when I was a kid. When something overheated like that, 90% of the time it was a short or a the wrong value of component. It's possible the drop caused the antenna connector to short out. Try disconnecting the antenna cable and try again with the stock radio firmware and see if the radio continues to overheat.
(I'm not sure how flashing the radio would prevent overheating, unless the original firmware simply turned up the transmit power in an effort to contact the tower, but that's my first guess and should an easy thing to eliminate).

Thanks for replying! When I get home I will give it a shot and see if it still overheats, then update this with my findings.

If it is overheating then it must hardware issue. Worst case is that the PBC board has a crack somewhere because of the bent. Grab the service manual from the general forum and start mesuring the components to find out where is the problem.

It seems to overheat with our without the antenna cables on the stock radio. I noticed that it still gets warmer than it should with the G2 radio, it just takes a lot longer.
That service manual is really comprehensive but unfortunately, it is going to take me some time to actually get to looking it over closely.

Screen Flickering

I've read a few threads on the screen Flickering and there doesn't seem to be any resolution .
I'm on my 3rd tablet now (thanks best buy accident damage warranty!) And this one is flickering worse lately than ever. I updated to the latest firmware, yesterday only to boot up to horrible bouts of flickering during the setup screens.
The odd thing is, there seem to be no consistency to it. Some days it's so had I can't even use the thing, other days it doesn't happen at all. I use the tablet every day for notes or PDF viewing. I've used it with no magnetic cover (totally naked) and with the cover.. doesn't seem to change the occurrences.
I've turned overlays on/off force gpu render on/off.. nothing seems to fix it. Sometimes changing the overlay will reduce the flickering other times it doesn't affect it at all.
I hate to say it, but if I can't resolve it, I'm going to be forced to move to the surface 3.
I'm an electrical engineer and I've done as much trouble shooting as I can think to do.. but I've come up empty handed.
Anyone else have these problems? Has anyone found a definitive fix?

I sent mine back 3 times. The first was a reset. Thanks for wasting my time. The second was a motherboard and that didn’t do it. The third time they did a motherboard, digitizer, and usb port. It's finally stable and back to normal. After 5 trips back, the BB warranty triggers a new unit. Check if it triggers a refund.

I get it occasionally, so far I'm able to resolve it by booting into custom recovery (TWRP) and clearing dalvic to allow all apps to rebuild. Sometimes this resolves it for a few days, sometimes a couple of weeks. Its a repeatable "fix" that makes me question if the issue is related to memory or trim or something like that. Kind of reminds me of how with the first generation nexus 7s one would see slow downs after a while and filing storage with fake data then deleting it would improve performance for a while.

I'm definitely not a tender user of the device. I go back and forth between multiple ROM's and kernels on a daily basis testing what is testable, and unfortunately also what is not. Anyway, even though mine was bought as refurbished on eBay, I have never had any issues like the ones you describe. More specifically, I have never had any issues what-so-ever, that was not created due to my own ignorance. To me the device seems indestructible.
Besides, I would hate to be in the place of my device, or I would definitely have turned schizophrenic. Should I feel bad about pushing it through all this?

Because we're trying to figure out if it's related to a specific device type, which one do you have? P900, 905, 907A or another?

P900 wifi. Us version bought at best buy.
Today the tablet has been rock solid, I have literally done nothing between when it was flickering like mad and now.
I wonder if it might be related to some kid of data transfer. either over wifi, or when data is written or read from storage or SD card. I've take then SD card out to eliminate that as the problem.

Mine was P900 from BB

Issue lies with the screen.
This happened with me I sent it back to Samsung, 3 times. They seem to have finally got it right. They replaced the battery and then the display screen. Now it appears to be working I will let you know after a month if it is still good. They also told me that they will not replace the device even though I bought it and the issue was right from the start. Not even 6 months old. When working the device is excellent.

Ah, so now we know for sure the battery is replaceable. That's good news. Maybe someday our batteries will no longer hold a charge and we can replace it. Now for a good video on tear down and what tools to use to do that and where to get a replacement battery. I know it's early for most of us but someday......we will have to replace that battery. I'm one of those that keep my toys (computers/laptops/tablets/phones,) for many years.

Mine is running like new since last service. Getting the BB Geek Squad warranty has paid for itself already. I get 2 years on anything over $500.

Mine is a p900. I purchased from samsung website. Mine has been doing it fresh out of box. So bummed.

Ive had my 12.2 since march and it recently started flickering. It seems to tuen of the screen for a millisecond especially when lots of refreshes happen. Like scrolling a pdf. A few days back it was bad. Now it has gotten better and I havent noticed anything.

My P900 has just begun flickering exactly as you describe. So I should just be patient and hope it goes away by itself?

I'm flickering again. Turning the screen brighter is what triggers it for me. Returning to stock just to get it back and have it flicker again to hit the magic 5 returns may be what I have to do.

Lifting the motherboard only temporary close the gaps of cracked battery connector. The permanent fix need to do: re solder the battery connector.
Look closely under magnified glass or microscope , you'll see the cracked solders. You can test by pushing the connector slightly, a bad one will move easily or lift off from its solder joints.
This video was removed from the poster after I pointed out his guessing solution. Flickering screen has nothing to do with LCD connector on the motherboard.
Lifting mother board actually you're applying pressure on the battery connector from rear cover.

I have had my P900 sent to Samsung service twice without having the screen flicker fixed. I thought this was a known problem and that Samsung themselves should be aware of it? Maybe I should supply some XDA links next time...

Second time, battery connector was replaced. Since then it has worked very very smoothly.

Depend on where you send for service, they know how to fix it now. Service Centers actually are contractors provide services for Samsung and others, the fact that most people don't know.
