Droid 4 Shutting Off Randomly

About a week ago my D4 started to randomly shut off. Opening the keyboard, using Dolphin, or just sitting in my pocket. I am unable to turn it back on without plugging it in to a charger, like it needs a jump or something. Once it fires back up, it says I have plenty of battery. The only other thing I see is when I plug it in but don't turn it on, it says it has 0-5% battery. It is rooted with safestrap and Eclipse installed but I've been running the stock version because some things weren't working quite right in Eclipse. Iv'e seen some posts say it could be a battery problem. Others say to factory reset or SBF. I'm going to give these a try but does anyone else have any ideas? I bought it off ebay a month ago and I'm worried they might not honor the warranty being purchased second hand. Luckily I still hadn't sold my trusty D3, but I dowant to get the D4 back in operation.

I've seen this problem with a few other of my older keyboard phones and it was always a hardware issue. I bet a ribbon has pressure applied to it so that the system briefly doesn't detect a battery...

I figured something like that. Weird thing is every once in a while if I plug it in to the charger it will show 5% battery, then go up to 10% after about 20 minutes, then suddenly shoot up to 100%. The phone would work fine off the charger for about a half hour then die, rinse and repeat. So it is charging but only like 5% then it will show 100%. I'm probably just going to bring it in and hopefully get a replacement.

Well I ended up calling Verizon and they are going to send a replacement, no questions asked. Apparently it doesnt matter if you bought the phone second hand, they will still honor the warranty (or I got just the right CSR). Case closed.

Really? They told me to f* off last time I called about warranty off a phone from cl... lol

I was guessing they were going to tell me to F off as well since most people were saying that's what they do when you try to get a warranty replacement on a second hand phone. It was literally the best experience I've ever had calling any customer service line. Told him my phone wouldn't stay on, he said he was going to talk to an engineer, next thing I know he's asking for my address. Win!

interesting.. will call tomorrow (my earpiece speaker crackles) >_>

Just got to get the right person to answer. My guy actually sounded like he was based in the US, not Kazakhstan. I told the person on the phone my story and that I had already gone to an authorized retailer (which I did) and that my phone wouldnt stay on. Put me on hold for a minute, came back and said were going to get a warranty replacement out. What may have helped is that I had my D3 active on my line and D4 was deactivated, so maybe they couldnt look up the info that would flag it as not from original buyer.

Mine does this too. Not all the time, just enough to irritate me. I've been putting off calling in to get a replacement because I'm worried whatever they send me will have more problems than just a crackling ear piece.

Whoops forgot to update. New phone definitely has less crackle. Old one was very noticeable, new one has little to no crackle. Only thing was it wasn't updated when I got it, had to manually go in and have it update to 219. I don't use the rear speaker very often but I don't remember it having a cracking sound. All in all there are no issues with it

Replacement nexus 4 lost or stolen......or so I thought.

So my replacement nexus 4 was suppose to be delivered on Monday. Around noon monday, I check the tracking which said it had been delivered...except I was home all morning and no package was delivered. I waited a few hours, figuring it was some kind of mistake with the tracking.
Then, I called UPS and they confirmed that it had been delivered at the stated time. I immediately called google and explained the situation. They were very understanding and started the process of disabling the lost device and issuing me a new one.
However, later that evening, my neighbour rang the bell and had the package in his hand....he had just come back from work and found it sitting at his front door (arghhh UPS ). At this point I hadn't yet received the e-mail from google with the link to order another replacement, so I figured I would call them to let them know that I had found the device. The rep told me that she would send the request to the department that handles lost/stolen device, but it was most likely already too late. She said she would keep me posted on the situation by e-mail.
Today, I still haven't received the e-mail with the link to order the new replacement, and the device is working fine (I assume if they disable it, it would lock me out or something). So I e-mailed the aforementioned rep and explained this to her. She e-mailed back saying that they had already disabled the device and given me a full refund, and that I would have to reorder the device...wtf On top of that she made no mention of returning this device (But I did go ahead and mail back the original phone today).
The phone is still working fine and my credit card doesn't show any refund (though this may be due to the fact that they haven't yet processed the refund....just my guess). Oh and still no e-mail to order the replacement, but I'm assuming since they are apparently issuing a refund, they expect me to place a whole new order?
What do you guys think? Is this just a big miscommunication between the various departments at google? Did they indeed stop the disabling of the device (which would explain why the device is still working)? But then why would the rep tell me I need to reorder the device. Man, this is just a big mess......and the funny part is, this device has the same earpiece buzzing problem for which I did the RMA lol.

Mine is from the Nov 13th batch of orders no buzzing in my ear piece. My neighbor ordered on the 7th and received it on Monday and it has a buzzing earpiece so I don't think that it has anything to do with what batch it came from.

They said once they remote disable the device it will basically become a paperweight. I have no idea of exactly what they do. Can anyone shed some light on this? BTW phone still works.

Why would anyone hold up their phones to their ears when it is not on or even on a phone call??!
is this like the "if I shake my phone real hard, I can hear something rattling inside" complaint?

I can't believe you mailed the phone back before even receiving the e-mail with the link to get the next RMA unit. If I were you I would have kept the phone until it either stopped working or you placed the next RMA order and had the next replacement in hand.
Now who knows when you will get your hands on another N4. Looks like you are in a whole new limbo period.

I think what they do is void the ESN on the device rendering it unusable as a carrier cannot activate a bad ESN.

I can clearly hear the buzzing while on a call on both the original and the replacement phone, and it's really annoying. Obviously if I could not hear it in a call, it would be a non-issue.

I mailed back the original phone that I ordered on Nov 13, not the replacement. The rep said that I had to mail back the original right away to avoid being charged for it. Like I said, the replacement phone is working fine (except for the buzz lol) and so far as I can tell, they have not "disabled" the device in any way yet. Even if they do, I have a perfectly fine HTC one S sitting here that I have no problem using.

Sucks man, sorry. I would've tried to keep that thing as long as I could. As far as the buzzing, seems like all these devices have a shielding or grounding issue which is causing the noise in the ear piece. My first phone which I got from TMobile (I love 30 day return policy ) had a pretty bad electrical/modem sound that was actually very distracting while in a call. The new device which I just received yesterday from El Goog doesn't have this defect, but does have the sound of an active earpiece at all times. Hardly an issue. The previous device sounded really bad over VOIP and calls never sounded as good as with the new one. Best to be patient and satisfied rather than hasty and regretful
Good luck man!!

Update
So I just got an e-mail from another rep saying that they were able to stop the deactivation of the device. lol. No wonder why the phone has been working all along. I think I'm just going to sell the phone since I don't want to go through this whole RMA process again, and it does seem like this buzzing happens on all nexus 4s. I'll probably order one again once these issues have been worked out. In the mean time, I think I can get by just fine with the HTC one s that I picked up brand new for $100 last week

Defective Sprint replacement phone! Argh

- I am in the employee advantage club so obtaining phones is a little different or somewhat harder in some cases being that you have to wait for the employee to approve it.
-Anyways I had my HTC ONE set up perfected, but the camera was becoming increasingly worse with the purplelicious pictures.
-Picked up my phone today from my contact @ sprint and it was all sealed nothing was out of place and it looked good.
-First things first checked the hboot, baseband and android version which is on I 1.44 and android 4.1.2 and so I was happy.
-First thing I noticed the dang power button was messed up when I pressed it it would sag to the right and go inside the phone. I called sprint to activate it the phone once I got it on and it took about an hour of changing ## numbers. Finally good but...
-Now I am thinking maybe i can live with the power button but i noticed something else; there was now vibration from the phone what so ever. I checked every single dang option and everything is enabled but still no vibration. Well I called sprint and gave them my rant about their quality and assurance control which I was very pissed about after waiting sometime for the replacement. Then called my Sprint contact to reorder another phone but this licks. My phone was in prestigous condtion despite the camera and I receive a much far worse phone in return.
Anyways end Rant-
I am curuious if anyone else has had a similar issue with the vibration function not working or just receiving a shady phone all together.

I've been lucky. My first phone blew the top speaker but my second one is perfect. Neither of them had the camera issue.

Had my phone repaired. It came back with scratches (yes, scratches that I KNOW were caused after they opened and processed it), and gaps, and glue out the corners, and a crappy power button. It was dropped once by a person I was showing it to (had taken the case off just for them) and who tried to press the power button, resulting in it falling onto hard tile from ~5 feet.

I must say I have been lucky as well in the past especially with my OG EVO'. They sent brand new ones no questions asked. I didnt have to use Total Protection either for the defects.
I never knew that the purple haze was really an issue. A lot of photos without a quality camera don't work well at night unless you are good at tweaking. Unfortunately mine was getting progressively worse even in good lighting conditions. Sprint will make it right, but it more less a convenience issue. I thought I scored too with the 1.44 Hboot hopefully the next one will have the same Hboot.
I took the firmware update on the defective phone. I get much better battery life on android 4.3 IMO. I wish I could walk in the store and say my phone is tweaked can I get another and call it a day, but being in the discount program with the huge savings I am considered an employee and have to wait for regular or new consumers to get items first.
Thanks for the stories and replies.

Camera lens movement

So long story short, the lens jumps up and back down while holding the phone trying to take a picture. It stops however when the phone is stabilized on a table.
I guess my question is, is there anyone else who is experiencing this? Do I have a defective device, does the OIS think I'm moving much more than I really am?
Here is a YouTube link recorded by me very clearly showing my issue.

Have already seen this issue. Factory reset seems to solve it.

It was doing it before I unlocked and rooted, which did a factory reset no? Also different camera apps reproduce the same issue.. I can't seem to find another thread with the same issue, can someone post a link? I'm pretty concerned and am thinking about getting a replacement...

i posted about my issues in this thread. seems that it was a hardware issue and T-Mo replaced it. no problems since
http://forum.xda-developers.com/showpost.php?p=57450996&postcount=78

My nexus 9 did this. I could hear It move after taking a picture or while panning around. It was rather annoying which is another reason why I returned it.

I've just had this exact same issue. I got my phone on the 8th of Dec and it started for no reason on the 25th. I tried a few full wipes, and also tested it on a couple of alternative camera apps with no joy so it's been taken back to store today.

I called google and just got an RMA to send it back once I receive the new one.. They sent me a link that took me directly to the check out portion of play devices.. Play store shows them out of stock however my order was successful.. Now let's see how long the new one takes to arrive.
Edit: ordered it today (26th), email confirmation said it should leave the warehouse by the 30th. :thumbup: ups standard shipping 2-5 days.

Ive got an rma with moto for mine.

Camera Lens Movement
Yes bro ur right. My nexus 6 also is facing the issue and im getting a replacement

Yup, I had the same problem, and just got a replacement from Motorola, definitely a hardware malfunction.

I'm seeing the same issue you're seeing. Motorola customer reps sucks too. I'm trying to do the advance exchange program but my card got rejected 3 times from motorola's system. This also happened to me when purchasing the damnnn phone. Hopefully 4th time is a charm if not, motorola better figure this **** out. They even asked me to use a friend or family member's credit card. WTF is that!!! First time it failed because my CC billing and shipping was different. So I called my CC to change my billing addy to my work addy. Tried again and still got rejected.

Camera Focus Problem
Another casualty . . . focus problems. Just talked to Motorola and a replacement is being shipped.

Ok so i have had my N6 since December but only used the video yesterday. It suffers the same problems as above that I will not focus on a object and keeps going in and out of focus on its own.
My dilemma, I bought it full retail from T-mobile, did not activate it on T-Mobile, instead I dropped in my Verizon SIM and have been using it on Verizon ever since. So I notice the camera problem yesterday and I speak to T-mobile today. In a nutshell they are refusing to replace it through a warranty exchange (new or reconditioned) because I never activated it on T-Mobile and I don't have an account with them.
T-Mobile sent me to Google (30 minutes of my life that I will never get back) who tried to tell me it was a software issue. When I told them I'm sure it was a hardware issue they sent me back to T-Mobile despite telling them that they sent me here in the first place. Round two with T-Mobile and they again refuse to warranty the phone and give me the number to Motorola (which actually makes more sense).
So the question is now, how is the Motorola warranty process and will I have to play "20 questions" like with Google? Will I have to send them the N6 first or can I hold onto it while they ship me another one? How long will the process take?
Another option I thought of, I could activate the N6 on T-Mobile with a pay as you go plan and then have them warranty it since now I do have an account with them. I still have the T-Mobile SIM that came with N6 so I don't think it would be that difficult.
Or should I just raise a stink with T-Mobile and demand they warranty the N6 regardless of my account status.
Any thoughts?

I did the exact thing you did and I called Motorola. They sent me a new phone in a factory sealed box (no refurb.) Just call them, tell them your issue and you'll be taken care of.

it's hardware issue, send it back to Motorola for a new replacement, or repair by yourself

Ok so I activated the N6 on a pay as you go plan which cost me a total of $13.00. Well turns out that T-mobile would have to send in the phone first before a replacement is shipped on any pay as you go plan. If I had activated on a monthly plan then they would have sent the replacement first.
I ended up calling Motorola and after a lengthy hold time my replacement N6 is enroute. Hopefully this will end my camera problems and not start any new ones.

Xperia Z3 compact, the most disappointing Sony phone I've ever used.

Hey guys, I just wanted to share my experience with this device with you.
So, I bought this phone in January and it was the most excellent phone I've ever used, fast processor, good camera, a nice community backing it up, good audio, you know the rest.
But it wasn't until, like, three or four months after that and I began to have troubles with it. I'll try to list them up:
1. While using it for reading before going to sleep, it would lock itself as if I pressed the power button (and no, it wasn't because of the screen timeout because I have a very high timeout and whenever it locked itself it made the locking sound it normally does when you press the lock button). I guess it has to do with the position I usually hold it when I'm on my bed and about to sleep.
2. Vibration motor issues, the phone used to stop vibrating at random times, I had to give it a shake to start vibrating again, how can you explain that? How is that even possible? God, I just can't understand what was wrong, but I learned to live with it
3. Video playblack issues, it stopped playing any kind of video at random times and I had to reboot it so it could do it. For example, YouTube showed that there was a problem loading the video, Instagram videos would glitch and go black, Snapchat videos won't play, you open the video and it exits as if it has finished, Album app says "Cannot play video", Facebook videos would just show the preview and the loading would remain at zero, and so on... However, this got fixed when I updated to Marshmallow but had to live with it for at least two months until MM released.
4. Audio jack issues (first issue), when I plugged my headphones everything was okay, but when I twisted the headphones plug it would stop playing the music (twist the headphone plug, obviously not disconnecting it; let's say that you have a sort of L shaped earphones plug, you are going to watch a YouTube video so you put your phone in landscape, you rotate the earphones plug so you can hold the phone in landscape properly, phone detects as it was disconnected and stops the video).
And, finally...
5. Audio jack issues (second issue), the headphones would disconnect no matter what I do, even the slightest movement would disconnect it, this frustrates me because I listen to music A LOT, and I couldn't do that on my phone anymore. When trying to disconnect and reconnect the headphones the audio jack cracked and the plastic frame of the phone got unglued, and now I have the chrome audio jack and the plastic frame in my hands because I can't glue it back because it won't fit again.
The last issue just happened a couple of hours ago.
I am so disappointed of this phone, just when I though I have found the perfect phone for me, guess I have to try again with another brand... (not to mention I have seen in a lot of forums that this phone has a lot of issues in terms of hardware and software).
What do you think? Have you had any problems like this? Do you think I have bad luck?
What do you think I should do now?
Leave the comments, I will read them.

Sadly, no. I bought it from a shop where they sell unlocked new phones, but I think that the warranty from Sony has expired.

If it was a new phone in January it has warranty. In Australia it has a two year warranty.

In 4 years of having Xperia phones I've only every had one problem, a cracked screen. I called the service desk and they gave me an address to send it to, I had a new screen in 5 days.
I doesn't matter if the phone was second hand or sold unlocked, it still has a valid warranty (two years in Europe).
Register your phone, you will need the IMEI number.
Then call Sony service and tell them you have a fault. They will talk you though some stuff, get you to try PC Companion, then give you a fault reference number and an address to send it to.
It's worth a try.

i only had audio jack issue that makes weird sounds

I've been using Z3 Compact for about 1.5 years. Believe me man, I dropped my phone into wet cement and cement sucked the phone in, phone was covered in and out in cement for at least half an hour. You know what happened? I went home and washed it, then brushed it to get rid of the dry cement. It still works like a charm! You must be very unlucky.

Best phone I so far got in my Hands. The Camera is the only drawback, but hey, there are mods and fixes. Never had an issue with that phone, it´s a beast in terms of speed and battery, yet tiny enough to fit anywhere in. Yours´ must be a refurbished or something. I´d recommend that phone to anybody I know.

It's a great phone. I dropped this thing (with a tpu case, though) A LOT. I must admit the headphone jack went bad on me. It's short circuiting, so I bought a replacement part.

headphone jack died for me as well. had to order one and replace it. we're not alone in this, google it and you'll find it died for hundreds of people more (who use this phone a lot for music)

Did you replace it yourself? I'm too afraid to do it myself. You have to remove almost everything in the phone to reach the headphone jack. Could a regular cellphone repair place do this job?

I replaced it myself because I said screw it, if it works afterwards, then great, I'll use this phone for longer (but won't ever buy a sony phone). If not, I would've bought smth like a 1Plus X at that time (not spending 500$ on a new phone ever again, I bought the z3c in Oct 2014 when it was just released).
Ordered replacement jack from a chinese online store for 10$.
To my surprise, everything worked as before. The good thing about the components is that you don't have to weld or glue anything, it's all with contacts/sockets. And of course you need some guitar picks, tweezers and a suction cup. You can use a blowdryer instead of a heatgun like I did. Of course it won't be waterproof after that, as you can imagine, the glue on the back panel will only be good enough to stick it back on (doesn't fall afterwards, you just also heat it up a bit before putting it back).
The instructions in this video, before the 3:08 min mark is all you need to do. And then just reverse the process.

Also I had great satisfaction from the fact that I did all this and actually fixed something. Process took place in March 2016, so it's been around 6months already and the headphone jack works with no flaws.
P.S. Didn't bother taking it to a cellphone service/repair center since, at least in my country, they don't have that much experience with repairing waterproof phones. Actually I think they pretty much refuse to do it. Also official Sony centers don't service phones here, hah

So, I am proud user of Z3C. After 14 Months, I've had no problems at all. Camera takes perfect photos, music is great on speakers and NC headphones or even with Sony MDR-V150. Only thing I would like to have is RAW format for photos...

Amazing device with horrible design flaws a.k.a = the jack of death
The worst part of this story is that this sh*t (the jack) got ruined after long time of use, which means: out of warranty, you will have to f*ckyourself and deal with it, because Sony give a sh*t about it and will never recognize that flaw... ever.
Workaround? BT headphones
Downside 1? Latest Radio.apk + MM = No FM radio over BT, music only.
Downside 2? Money, obviously.
Pretty sh*tty scenario for an almighty compact device.
Bottom line: If your jack is ok, dont mess with it... just remember those many customers fallen in this adventure named "Flagship".

Yay, my headphone jack is broked now. Nothing more to add; just wanting to wallow with some fellow sufferers Still in warranty so will try that approach out.
