Develop Bugs

Impressions & Questions

I've had this phone for a little over three days now. Overall, I absolutely love it. The only smartphones I've ever owned were the Evo lines, so this was a big leap for me, and I'm not sorry. However, there are a few issues with it.
First is a strange antenna issue. I have the Sprint version of the Optimus G, updated and rooted. When the network mode is set to LTE/CDMA, the 3G antenna will only turn on very rarely, leaving me entirely without internet access. I was about to return in when I realized that the issue is solved when I change it to CDMA only. We don't have LTE in my area, so I don't mind leaving my LTE antenna off. I'm not sure if it's an issue with my phone alone, or if it's a software issue that others have.
Then there's the screen. The screen itself is BEAUTIFUL, and I have no issues with it. But the screen scratches like crazy! I am extremely careful with my phones, and this one in particular. I kinda bought it on impulse, so I didn't have time to order a screen protector for it (one should be in tomorrow though). So I have been treating it with extra, almost paranoid caution. It's only ever been in my pocket while at work (nice khakis, so nothing harsh), and otherwise it's been undisturbed on a table. I check my pocket for any abrasive lint often since there's no screen protector on it. But the screen has developed about a dozen or so scratches, and one of them deep enough to distort the screen when it's on. I don't know how this is happening (the deep one happened in the space of five minutes, inbetween two texts, and was merely put into and removed from my pocket.)
Also, the battery life is kinda crappy. I live near a tower, so always have full signal. At work I'm on wifi, so that's not an issue. The battery scarcely lasts through work, with VERY light usage, and is nearly dead by the time I get home. Today, from the time I woke up with it at 100% to the time I got to work (about 2 hours, with constant near-full signal), the phone dropped from 100% to 76%.
Are these normal issues, or am I the only one experiencing them? I want to love this phone so much, but these seem like serious flaws to me.

I too had to change to CDMA so dont know what is wrong with that. And the scratches is weird ive dropped mine a few times and dropped my keys on the screen and nothing. And my battery is phenomenal. Seems like you have a dud.

In regards to the screen....this may sound like a stupid question and I don't mean to offend, but did you remove the temp screen protector that it comes with? I've not had one issue with my screen being scratched and I can't say I've been all that good to it for the last week.

I've had the phone for a full week now and I have not experienced 3G drops with LTE/CDMA mode enabled. Also haven't scratched it either (thankfully). I constantly put it in and out of my jean pocket throughout the day, so I don't really understand how yours got to be that way.
As far as battery life, I too don't see the issues you're having. Typically I pull it off the charger at around 7AM and can easily get 12 hrs+ with normal usage. Even with Android OS taking up the bulk of my battery (seems to be awake a lot). Lot's of people saying its a battery drain bug, etc. etc. etc...but if I'm getting 12 hrs easily, and 24 hrs with light usage, I don't have a problem with that.
-Screen brightness at 60%
-Wifi on all the time (connected at home and at work - probably helps, lol)
-2 Gmail accounts pushed constantly, Facebook messenger, and a few other apps that auto-update on schedule (news readers n stuff)
-My commutes to and from work - I listen/watch podcasts and/or read. Which means the screen is on the entire time (approx a 1hr commute). All said, my screen-on time sits at around 3 hrs for me.
I'll post some screenshots in a minute...

No scratches or weird battery issues here. My first two days the battery life was horrid. Afterwards I did some update and poof like magic.
Anyone have any info on the boot loader unlock initiative? I miss aosp

got this phone for sprint yesterday after having a BB for 5 years .. and i'm loving the beautiful screen,.
Only hiccups is maybe the battery... Yesteday i had it full on 100% then after 2 hours went down to 80%..
I'm currently in the office charging the phone to 100% will remove it and do normal routine on it and see how long it last.

Haha, I actually checked for this before posting. It is absolutely something I'd do.
After reading these and other comments about the phone, I realized I probably had a dud. I went to the Sprint store a couple days ago and swapped it out for a new one, and it's running beautifully, with none of these issues. So I guess I just got a faulty one. Thanks all for responding!

Good to hear! Sorry, I had to ask...my girlfriend had the same problem with her phone she got a couple months ago and it was because the temporary screen protector was still on the phone!

Anyone finding it gets kinda hot? I've read some owners complaining about this and it was mentioned in some review somewhere. Wondering how widespread it might be. Might be that people keep all 4 cores running 24/7. I don't see the point if you're web surfing, talking, texting. I keep it on Eco Mode most the time.

I've only notice it get warm once or twice, but even then it was barely noticeable. But I've had eco mode on since I got the phone, and it's not hesitated or stuttered once.

We are thinking of switching to Sprint, so we went to Best Buy and picked up one of these phones and I'm very impressed with it so far.
Actually this is the second one because the first one had a factory defect in the chrome around the screen. It get home with the 2nd one and notice there is a speck of dust under the glass.
I'm going to return this one in a day or two and see if the third one is a charm. If not, I'm not getting a forth one!
Any suggestions on a different phone for Sprint if this one doesn't work out? To me the only other phone to get would be the Note 2 and then the GS3.

A little help here guys. I was planning to return mine because of battery problem. Like i tried playing Dead Trigger, current battery is 54%, 30 brightness, sync and data is off. I played for good 5 minutes and it dropped to 48%. One more test is after it got 100% full charged, i unplugged it, Wifi is on still 30% and not using it for a couple of minutes it dropped to 97% and im not even using it!
So i want to return it.
The question is:
Do i have to pay for replacement? I got mine at BestBuy for 99$ almost a month ago.
2nd is will still they accept it now it got scratch on four sides. Any suggestion?

As long as it hasn't been over 30 days and the phone doesn't look "abused" then you should be fine, also if it's been under 30 days i would add geeksquad protection especially if you plan on rooting, i thought it was a bad investment at first, then when talking to a tech after my evo4g bricked he just said to "make sure the device doesn't power on" and they will replace it needless to say i took a ballpeen hammer too it and got a shiny new one 2 days later.

I took the LG back and got the GS3. I've already had to clear the cache on the galaxy because of excessive battery drain.
If the GS3 fails me, I'm gonna try the Note 2.

Yep, on eco mode the battery is outstanding. The phones is faster than my wifes S3 on eco mode, and I get nearly 2 days without charging. I had the note II for a week and that is just as good but was too big for me. This phone impresses me everyday.

[Q] Does Galaxy Note 8 suffers from heat problems ?

Hello to all Galaxy Note 8 owners',
I've read most of the review online, but only a few stated about the heat issue on this device.
So, my question is does your phablet overheat ?

Uh... no? This is about the coolest running tablet on the market. Also, I have read every single piece of literature and commentary on the internet about the Note 8, and not once has heat been mentioned. Where, exactly, are you reading this?

Mine runs perfectly. No heat issues whatsoever.

I haven't noticed much heat or warmth at all, much less heat problems. I'm not a tablet gamer. But I do watch video, and download files (sometimes big ones and using Advanced Download Manager). And not heat issues.

Mine gets pretty warm on the lower lefthand side of the back plastic. Probably 10 degrees over ambient temp.
This is consistent with other devices that run at relatively high clock, or my phone if the wimax antenna is on - I'm not seeing it as a problem.

The only time I have felt any excessive heat, is when I was watching Netflix and charging at the same time. I use this tablet very heavily and have not noticed any heat issues!

Haven't read anything about heat issues on the Note 8 myself, nor have I observed any serious heat issues on mine. It'll get warm with intense use, but no worse than other tablets or phones in my collection.

Correction, only one on the net.
This is the link "hxxp://pocketnow.com/2013/04/09/galaxy-note-8-review"
Quoted here the relevant paragraph
-- "Other than that, the performance on the Note 8.0, even during graphic-intensive games, was exceptionally smooth. Though, after several minutes of intense gaming with the display brightness turned up, the device did tend to heat up a bit, but not to the extent the device was uncomfortable to hold." --
I'm asking because I've read heat problems on Galaxy Note II and Galaxy S3
Thanks for all your reply. It's good to hear that this one does not suffer from heat issues. If it is, I'll have to switch to Asus Fonepad, man.. that thing is half the price than Note 8

Device warming up is not the same as a heat problem. My S3 and the Note 8 will both get warm with heavy use, but so will everything else. You have to have realistic expectations on a device that only has passive cooling. Heat is a problem if it causes the device to crash or otherwise misbehave.

Used mine to play a game with 3D graphics for an hour or two and it was only slightly warm. Tablet was sitting on my pillow.

Echoing this statement. My Note 8 gets noticeably warm on the left side even on lower loads. It's never become hot enough to be an issue though.

Ditto...
My charger does get warmer than my G Note 10.1 and my G S3...

Mine is just like any other high end tablet. Stays cool but gets slightly warm warm when used heavily. I have the 3G version.

overheating? Try meltdown!
A few months ago, my wife and I visited the local AT&T store and picked up a Galaxy S4 and a Galaxy Note 8.0.
While my SG4 is working beautifully, the Note 8 is unusable, even after having it sent in for repairs (the problem persists as if it was never repaired).
Basically, it has a glitch that I've seen before on PCs that have a heat-damaged GPU. When the system is booted, it displays a graphically garbled mess and will not achieve full boot.
We have reloaded it, to no avail, and as I say, it's already been sent in for repairs yet it came back to us as if nothing had been done to it at all. It worked intermittently, as i had before the repair, so my wife tried to make due because we couldn't take time off from work to go back to AT&T in the last few weeks since we received our Note 8 back from Samsung (or whoever they farmed out the repair to). In the last few days of my wife using it, it's gone from intermittent to full-blown unusable. Now, about 15 to 20 seconds into the boot sequence, the GPU overheat glitch rears its head. There's no way now to get to the desktop to attempt another reload... but that wouldn't help anyway. When we last took the unit in for repairs, I reset the device to factory defaults at the request of the AT&T rep that was assisting us. Within 2 minutes after booting back up, the system was nearly unusable.
It was a rockin' little tablet... for about 4 days until it started overheating. I'm figuring it's likely a manufacturing flaw, based on the testimony of others that for the most part claim little or no heat issues.
Now, I'm not sure what we can do to rectify this. I hope we're not stuck with what amounts to a brick.
FYI / background-info: I've been a computer user for 31 years, and worked professionally in IT for the last 15 years. Embedded hardware hacking and embedded systems development are a few of my many technical hobbies. To say the least, I've been very thorough in my examination of this problem, and have an immense amount of experience with a large variety of hardware, which is why I recognize the problem to be related to overheating damage to the GPU -- I've seen it plenty of times before... the summer heat where I live will kill a GPU if it's fans aren't cleaned monthly, due to the amount of dust that blows in from the plains states immediately to our west.

i have GT-N5100
the unit so warm (not overheat) if i played some 3D games for a few times.
left side of the note.
and maybe i suggesting you not playing much games or heavy games with this Note 8.0
i don't know about the other handheld, but note 8.0 almost suck my battery 1minutes : 1% just for play LINE I Love Coffee or any light-weight games.
BUT, if you do for work (write on S-Note or drawing or adjust some shortcut and setting) it'll be so damn long lasting battery, but once you play (at least) 1 game, you'll see the battery drain so much.
don't know how to fix this (even i already turn on the Power Saving and turn off another function except vibrate, and screen rotation, also wifi...because i use battery program..that program indicate use Mobile Data/3G more drain than Wifi)

That's how the first Note 8 that I was shipped was (my post about it is somewhere) it was roasting when it arrived and oddly the battery showed it as fully charged. Screen was a complete disaster, reset it and it was fine for a few days then started acting up with the heat and screen issue. I only had had it a week so I just asked for an exchange (at first they wanted me to go through the warranty to fix or replace it ha! No). Got this new one and have had no issues (except the wifi which I finally seem to have working but that's whole other thing), like others said it just gets a little warm on the left side but nothing like that old unit and nothing horribly burning type of noticeable.

"Somebody Get Me a DOCTOR...." The GNex Gone Bad Experience Thread !!!

Has your nexus gone bad? Suffered from a damaged speaker, fried CPU, broken screen or similar? Here's the thread to share your exprerience.
Personally I bought my Nexus, brand new on September/October 2012. Sometime on August 2013 a got caught up in an endless bootloop, even odin or similar tricks couldn't save the day so took it to the repair centre (Smartec Greece) and had it back after 4-5 hours with a new motherboard. Pretty fast- problem solved, didn't have to pay something, even though I never got to know which part actually gone bad.
That's about it. I also have replaced stock battery with a new one as the old one was draining faster than the speed of light, no matter what rom I was on.
So let me hear ya!!!!

The goddamn USB port issue, couldn't charge my phone, until I poked that little bugger in there to rise it up a little, created such a hassle

You were lucky, after a year and a half of use my USB finally took a sh*t completely. Luckily the insurance I use has no deductable so I had to fire up my old Incredible 2 for a few days while I waited for a replacement. I'm so glad we have nandroid. All I had to do is unlock the bootloader on my new device, put TWRP back on and restore my nandroid. No hassle really.

WOW!

The same happened to me but I let the battery drain and then charge it for a bit to eneter recovery mode to restore from a back up. Why didnt you do that? I think your problem wasnt just a bootloop problem.

Powerbutton becoming faulty.
Sometimes worked sometimes didnt

Trashed my charge port one morning getting out of bed with a bad hangover..Forgot my phone was plugged and snapped the port right off :crying: I just bought a new charge port flex from ebay for $10 and replaced it myself in about 20 mins

Last year my Nexus dropped into the sea, but luckily survived

My Nexus's battery was damaged so from phone service I got a new one in 2012.
Then My Galaxy Nexus got a screen burn-in ("ghost image") and in the phone service they changed a screen, but my Nexus got that screen burn-in again..
Everything have worked so fine and I never used any other kernels on my Nexus, than the stock ones by Google and CM's kernel and ofc. my modified CM kernel., I have tried some custom kernels, but I never liked any custom kernel. My Nexus has scratches on its cases but screen has always been clean and good. :3
I'm really happy, that my Nexus looks like a new one, but only that screen burn in is annoying

I am on handset number five; one blown earpiece, two cracked screens and the last one had the interface between the digitizer and the motherboard come loose. I was able to wedge some paper between the battery door and phone body to make it work until the replacement came in. Thankfully I got the phone when beat buy had them for free and ponied up for the service plan.

I'm past the 1.5 year mark with my gnex and the only issue I have so far happened when it fell from my recliner while connected to the charger. The micro-usb metal piece on the cable got bent from the impact and since then I get a weird buzz/rattle when the phone vibrates. Had to reduce the vibrator strength on fancy kernel to get rid of that specific annoyance.
This has been the case for about 8 months now and the phone is still charging fine. Why I don't know is if this is a symptom that will eventually lead to the dreaded no-charging issue that some have shared here.

Had to change whole charging strip. Gnex was showing frequent charging/discharging and battery would drain within an hour!

1.5 year old phone. Volume-up button doesn't work, and hasn't for some time. To increase volume, I have to press volume down and then move the slider up on-screen. No big deal. Also had the USB port break a couple of months ago and had to get it changed. Otherwise it runs fine. Still on stock 4.2 ROM, I keep the GPS switched off most the time, and also have all the lower-level Google sync stuff disabled (screw Google), and battery typically lasts a day and a half of average usage.

Had the Galaxy Nexus since release day and it served me well. It was fast and I only went through a few. Last October I got my Note 3 so I retired my G'Nex, but now I'm going to be using it as a MP3 Player that I can just leave in my car vs using my Phone all the time. Just looking for a Rom that turns it into the Android version of an IPOD touch.

WiFi is gone

I've had this tablet (SM-P600) for almost a year now & it has worked perfectly. Over the last week or so, the WiFi has been randomly turning on & off. Not just losing signal, but actually showing as off in the menus. As of this morning, wifi will not turn on at all. Just says "turning on" on the screen & sits. Never gets to the next screen showing all the open networks.
Everything is fully backed up so I went into recovery tonight. Did the full factory reset and wipe procedures. Tablet boots back like it is as supposed to, but wifi wont turn on when getting to that screen in the initial setup.
Tablet has been well cared in a case, not dropped, and not gotten wet. However I am still positive this is a hardware issue.
Any ideas for things I might try? Help!! Thx in advance

I've the same problem with my galaxy note 10.1 2014 edition SM-P605 :crying: Still haven't found solution

I am almost 100% certain this is some type of hardware problem. I tried flashing about 3 different ROM's and 3 different kernels, all of which successfully booted up. I finished by doing a 100% re-wipe (data & system included) & reinstalling a pure stock kernel and firmware. On every single revision, the words "turning on" would appear when clicking the WiFi option, but then it would get stuck. Message would eventually clear & I could continue using everything on the tablet . . . . . . . just no WiFi or Bluetooth functionality.
Final attempt was to gently remove the back cover. When lightly tapping around different points on the MoBo, the names of my local wireless networks would OCCASIONALLY appear. At one point they locked in & I really thought I had it. However, the whole thing disconnected again after a few minutes & I was back to square 1. :crying:
I never could figure out the perfect sweet spot to pinpoint the problem. My guess now is either a chip or ribbon cable that isn't seated properly, but I poked and pushed (gently!) on everything that was visible without removing any hardware other than just the back cover. Does anyone have a link to the layout of the motherboard that shows EXACTLY which piece is the WiFi/BT module? I did find an online disassembly tutorial with a random Google search, but for some reason they failed to identify this particular module.
Sorry for the long post, but I feel I am SO CLOSE to figuring this out once and for all. Just need a little more tech help to push across the goal line. Thanks!!

Update:
After a little more poking and prodding on the MoBo, I'm starting to see activity. Tablet will finally connect again, but will only hold the connection for 10-15 seconds and then drop back out. A few seconds later the cycle repeats.
I really wish I could find a good hi-res photo of the motherboard to help. HAS to be a simple loose connection, or maybe a not-so-good solder point somewhere???

never heard of 'em, is it a cheapo tablet? In my country there's a store of them (Allwinner 6.6" tablet with microSD slot, 2gb internal w/o bluetooth WIFI ONLY INTENDED FOR CASUAL GAMING, or should I call it kids only tablet, RM130 ($35))
That thing has a cheap plasticy housing, unneat design but has a pretty good performance (it plays dead trigger pretty well)

SM-P600 is Samsung's actual model number for the WiFi only version of the 2014 Galaxy Note 10.1. Most definitely NOT a cheapo tablet!! Although this wifi issue makes me wonder. I had the functionality back for about a day or so, and then it disappeared again. This has to be a simple case of a loose connector, but I sure can't find it. Ugh. Utterly frustrating.

oo...my bad
maybe software issue

What firmware version are you using because I am having the same issue. I manually updated to the september update (P600UEUCNI1) for the wifi version and started experiencing the same issue.

Same here. I think it's an issue with NII firmware.

*****PARTIAL solution*****
I have proven 100% that mine is problematic hardware . . . . . NOT software or kernel. For the time being my WiFi is back up & seemingly stable. I had to remove the back from the tablet for the fix. You have to be *extremely* careful, but it just snaps off with no screws. Lots of YouTube videos if you choose to attempt, but please don't say I didn't give you fair warning!
The reason I say partial solution is that I haven't pinpointed the exact location of the short. I am 99% sure it is somewhere on the extreme upper left hand corner as you face the front of the tablet. There are a couple of ribbon connectors in that area, and a few snap on type connectors that look like little motherboard chips. After gently poking & prodding the ribbons and disconnecting & reconnecting the snap connectors (being CAREFUL; I cannot stress this enough), my WiFi reappeared.
My final tip is to keep the screen on the page that shows the list of available networks. If you are having the same problem I was, this screen will just show "turning on" and nothing else for the WiFi. While poking around, I would occasionally see the list of networks pop up & then go back off. I finally hit whatever the magic spot is, and the networks held. Snapped the back cover on again, and I've been online for probably 4-5 days now without a single hiccup.
And before I get flamed, I know how dangerous it is to poke around with a powered, exposed tablet. There are probably certain points that could make connection and FRY the entire thing in an instant. I was just willing to take the risk as my tablet was useless without network capability. I had nothing to lose. I would recommend at least trying to poke & prod with the tablet OFF a few times to be safe, but I personally got tired of rebooting over & over & over & over. My luck sucks. With the tablet ON, I was at least able to monitor when something was happening.
Good luck if you attempt it!!

I've had this tablet (SM-P600) for almost a year now & it has worked perfectly. Over the last week or so, the WiFi has been randomly turning on & off. Not just losing signal, but actually showing as off in the menus. As of this morning, wifi will not turn on at all. Just says "turning on" on the screen & sits. Never gets to the next screen showing all the open networks.
Everything is fully backed up so I went into recovery tonight. Did the full factory reset and wipe procedures. Tablet boots back like it is as supposed to, but wifi wont turn on when getting to that screen in the initial setup.
Tablet has been well cared in a case, not dropped, and not gotten wet. However I am still positive this is a hardware issue.
Any ideas for things I might try? Help!! Thx in advance

I bought my Note in March of this year, I started having the WiFi issue after the April firmware update. At first I would get the Connected to... message at random times, even though I had full signal strength. At the end of September, I started losing connection at random times and in the middle of October, I had to send it in to Best Buy's Geek Squad service to have them repair it. It is a hardware issue, as the no matter what firmware version I use, it will never connect to the router. I know it, Geek Squad is aware of it, as I have sent it in for repair twice so far. I would have to send it in a third time before they will think about replacing it with a new Note. I will admit, that before I updated it in May, I did root it, because I tried to remove the Business Week+ and New York Times apps, as I never used either one of them. I tried disabling them, only to have them reactivate and update themselves.

Damn, what I read here is not good news. My SM-P605's died yesterday.
With Tapatalk on my Galaxy Note 10.1 (2014)

Hardware issue for sure. Same problem with mine. Opened the back case, disconnected the upper right (as your looking at the screen) small ribbon, reconnected, and boom, perfect wifi once again!

The EZ Package Disabler app is fine for debloating rooted and non-rooted devices with Touchwiz roms. It uses Knox, so that mustn't be removed. The apps are still on the system partition, but are completely dead now. While other apps, especually for non-rooted devices kill the system apps during boit and try to prevent their restart. But during boot the whole stuff is active until the app kicks in, allowing the system apps to receive updates, communicate, spam free flash mem etc.
The app wirks the same way on my rooted P605 and unrooted S5. And gives a reason to buy Samsung stuff, unlike Touchwiz and its bloatware. As far as custom roms go, i found that of my old LG L9 much better. Even if the early roms were AOSP 4.0.4 based, then 4.1.3, they had already had the fresh & bright look & feel of the future Kitkat, and a few useful enhancements like an integrated backup tool, which was more simple, but for me as useful as TB.
As for the main problem here, i think using a case with a hardened backside, and not one if these with a big hole(though being better than nothing), prevents oroblens like battery, display and seemingly wifi connectors loosening. Or bad solder joints. The backplate of the note gives thru any pressure on the back, especially in the middle area. It then rests on the battery, metal shields, connectors and stuff. This seems to generate enough wear over time for problems. The same back plate on a much smaller device(my S5, but that has a subchassis covering the innards, too) would be much stiffer, and my 7" tablet has an aluminium unibody case, such trouble is unknown there.

Hi Gents..
same problem here... I used to own a SM-600 purchased in 2014 unfortunately I lost it... (the first tablet worked without any proble until I lost it...) than I managed to found the same modell brand new on amazon... it worked for 2 weeks and 2 days ago wifi died... but funny enough not straight away.... first couple time just switched off the wifi... I managed to switch simply back... next day it only worked if restarted the device... now factory reset nothing... If it is hardware related why worked 2 weeks witout any problem? If it is software related why not working after software reset? Only installed a few apps from the store.. the device did not overheated or physically damaged...

I have the exact same problem.
Since I bought this a long time ago, I have to pay for the repair. I just want to know if it is worth it. How much did it cost you (if you bothered)?

In my opinion it would be foolish to spend a dime to repair a 4 year old tablet. If the battery is original, it may well be near the end of its useful life as well. FWIW, I bought this tablet used about 8 months ago and have not experienced this wifi problem.

It's still so well equipped, that you can't simply replace with a modern entry level or midline tablet, but with a top of the line one, so a repair is well an option.
I just don't have a clue about the SoCs performance level. To which current ones it would equal and where things get better. I can only compare it to my similarly(Snapdragon 801) equipped phone and my cheap 7" tablet's quad core Mediatek SoC, and that is considerably worse, though being three years newer.

hardware fault dead in under an hour

Well I'm disappointed!
phone arrived Yesterday. Worked perfectly whilst I added all my personal details then I decided to install asphalt 8, just to see how it performs (I don't actually intend to play it - can't stand the pay to win crap), and the phone made a nasty crackling sound and froze on the menu screen.
Powered down with power button, and on restart the screen is messed up with multi coloured lines running across it in various places. Then freezes, and reboots to repeat the process,the lines appear in different places. Sometimes makes it into the os, sometimes show the android error broken robot icon.
I'm guessing some fault with the graphic chip.
Luckily I bought direct from amazon so they are sending a replacement, but I have lost money on next day delivery, plus however much it costs to send back the phone (I'm in the UK but bought from mainland Europe) also not pleased my personal details are still on the device. At least I didn't import it from China.
Hopefully my phone was just a rare dud, and the replacement will be fine, as I can't find any similar reports online.
Anyone else had similar problems?

Yeah I would say that's a faulty unit. Sending it back is the right thing to do. Hope you get your money back

Well the replacement is great so far.
I noticed before the 1st one died that it was getting pretty hot on the back at the top, whilst simply going through the setup process.
The new one has been cool throughout setup, charging and about 3 straight hours of webbrowsing, so maybe the heat issue some are reporting is related to the hardware issue that killed my 1st one.
It does seem that quality control could be lacking, but as long as you buy from somewhere that offers returns, then i think its well worth buying.
I have just been using it as a mini tablet at home until i get a case and screen protector, so i dont know what the call quality etc is like, but battery on wifi has been pretty good.
Also, i charged it fully 3 days ago, and then left it on standby with wifi turned on and didnt use it. This moring it had over 80% battery, so standby time is much better than my s4 mini.
