Hi guys,
So I've gone on the HTC website again and looked at the specs of my HTC HD7 (as I have done many times before, e.g. when I was finding out the official "spec" for GPS on the phone - related).
Anyway, it seems that HTC have recently made a change to the specs page, they have split the internal storage size spec - 8GB for Europe handsets, and 16GB for Asia. I am 99% certain this was not the case a few months ago, it used to just say 16GB.
I happen to have 2 HTC HD7s (one bought from O2, one purchased offline, both acquired within a few weeks of each other - around Feb/March time this year):
Both boxes have the same P/N as each other, and also same model barcodes (6HTGD7XN)
Both boxes have identical specifications printed on them, also identical packaging and contents
Only discernable difference between them is that the O2 handset has a silver kickstand bed and the other handset's kickstand bed is orange.
Frustratingly, my O2 phone started its dying process after the Mango update. It never misbehaved before. Slowly and intermittantly at first, I would get random reboots, giving me "Memory card not working" error screens, setting itself as incorrect time, and even wiped itself a few times (meaning I had to reconfigure everything from scratch). I searched all over the net, checked and tried all sorts of remedies suggested on forums, e.g. doing a full factory reset, uninstalling all the HTC apps, disabling location services, disabling 3G/data connections, etc. Also I hadn't played any music with it since the Mango update either, so it wasn't the music player for which some people reported problems.
Sometimes the phone could go 12-18 hours without so much as a hiccup, and other times it would crash and reboot within a minute of starting. My SIM card has a PIN on it, so I always knew if my phone had rebooted itself. On average I'd say it happened a 2-3 times a day, though some days it would happen 10+ times.
Keeping my data connection turned off and only using Wifi seemed to keep the crashes at bay for several days, at least until today. I'm a fairly tolerant guy, but today was the last straw.
I was playing a new game I downloaded (Jewel³) when travelling to work, when suddenly it crashed and rebooted just like it did so many times before. I rolled my eyes and waited so I could carry on with it until the next crash, except instead of the usual process of booting up and acting normal, it kept crashing and factory resetting itself, asking me to configure the phone for the first time after every single crash/boot. That was it, now it was well and truly buggered. I took it to the O2 shop and they have now taken it in for repair. I assumed the memory card somehow developed a hardware fault, though the timing of when these issues started happening seemed too coincidental with the Mango update.
This is where my spare HD7 comes in handy. I've barely touched it since taking it out of the box brand new about 8 months ago (was meaning to sell it but never got round to it). I threw in my SIM card and began the update process using Zune. All updates successful etc but then afterwards I suddenly noticed the bottom of the Zune window. I went into the phone "about" screen, yep, 8GB total capacity, even though the box says 16GB.
So what I'm thinking is this: does the Zune Mango update patch actually recognise I am in Europe and try to flash the phone into only utilising 8GB? Even if the memory card has a physical capacity limit of 16GB?
If that's what happened to my first phone, that certainly explains the random rebooting behavior and memory errors, as I probably had parts of my data occupying the space which the Mango patch told the phone to ignore.
Just a hypothesis, anyone here got a 16GB HD7 in Europe which had a lot of data on it pre-mango, and had any similar problems afterwards?
It would also be interesting to know if you fall under this category and haven't had ANY issues since mango. I would like to try getting to the bottom of this, as my searches on the net seem quite fruitless (this was the best thread I could find, though I couldn't reply as I'm not a WP7 developer)
Mango is more sensitive to SD card timing issues... Check out the how to upgrade your phone to 32G in the general section... I benchmarked the factory 16GB card, a 32GB card that wouldn't work (constant reboots) and a 4 year old 8GB card... all Sandisk Class 4.
the 8 and 32 are undeniably not going to work, the FACTORY card is marginal, and I have been getting occasional reboots since upgrading to Mango. If I downgrade to NoDo, the reboots cease.
Ah ha, very interesting, and that certainly explains a lot. I wonder if my "repaired" phone will still suffer the occasional crash like your 16GB did. Would be nice to see which make of memory card they use (assuming they will replace it), though I don't want to void my warranty doing it!
For some reason, when I plug my phone into my PC and put the phone in Mass Storage mode, only the Internal Memory shows up, not the SD-Card. I've never had this problem before. The only thing I can think of that may possibly be causing this is the fact that my SD-Card is currently full, tho I don't see why this would cause it not too show up, but you never know. So I am hoping that someone on here has the answer as to why the External Memory Card isn't showing up and how to fix it so it does show up.
thankfully it still shows up in my phone itself and I can access all the files through my root browser, which I can use to delete, move/transfer files to and from the SD-Card and all that, but it's just a lot easier and faster to do it through the computer. So I really want it to show up like it normally does. Like I said, it's never not shown up before. I've had this phone for about a year and never had this problem with it. So any help fixing this issue would be greatly appreciated

Not exactly sure what to tell you, but do you have a micro sd adapter that you could pull your card out of your phone, insert it into you pc, transfer all files, format card, transfer them back and reinsert into your phone and check?
no, if i did I woulda just used that, but now that you mention it, thats a hella good idea, and I will remember that for the future, thanks for the info. Apparently it was just being retarded cause I just plugged it in, and bam, it worked lol it brought up both my Internal and External memory in Win7. I think its just the phone itself. It's always been a really finicky phone, and when I dropped it off this big rock, what they call a "Glacial Erratic" that is next door to my house
which, by the way, is the biggest Glacial Erratic in the country apparently, according to the newspaper and wikipedia and the US Geological Survey who came out and analyzed it. Which its kinda retarded they just figured that out last year, i moved here 10-years ago when i was 16, and even then I knew it was a glacial erratic and friends of mine who have lived here all their life knew it was a glacial rock too, tho they didn't know the term Glacial "ERRATIC" but yea, just figured I throw that interesting fact in there. Sucks now that it suddenly has become popular even tho like i said, its been there for thousands of years, and our house which is only like 20 ft from it, has been here since the late 80's, early 90's, and they just now "Discovered" it lol
But anyways, dropping it off that Glacial Erratic, definitely didn't help matters much hahaha, but even before i dropped it, its always been really touch and go with this phone. the drop, tho it did no external damage thanks to the case, seems oto have made it worse, and my batter doesn't last near as long as it should. I used to get about 6-hours on a full charge if i used it heavily/constant throughout the day, which now it gets maybe 3-hours if I'm lucky, and even with it just sitting there not being used, where it used to last well over 24-hours on light to no use, now it only last about 10-hours. I need a new battery....Hell, I just need a new phone. I really liked this phone at first, but not so much in the last few months, and especially now that i dropped it a couple weeks ago. Time to go get the Samsung G-III
So I took the windows phone plunge and purchased the Lumia 1520 Friday when they became available. Finally had a phone available I wanted with a memory card slot, which was a must have, and top end hardware, which was also pretty important.
I'm running into the same problems that most everyone else who changes from Android has with things being different, and not being available...but nothing major.
I have, however run into 2 pretty big things that may have me turning this phone in before the 30 days I have to do so are up, but I wanted to ask if anyone else is having these problems to determine whether it's just my phone, or a known issue.
I've added a Sandisk 64G SD card to the phone to store data, music, videos and pictures. Turns out it's kinda useless for data because of the lack of a file explorer ap, and the purposeful design to prevent such a thing. Ok...I can cope with that...that's what a USB key is for.
However...what I'm finding is that the pictures/videos/music I am putting on the SD card are being randomly deleted after I put them on the card. I've tried formatting the card using the phone, even going so far as to do a hard reset of the phone and bringing it up with the SD in it, and then formatting it immediately. It still randomly deletes files, mostly photos. I store a few thousand photos of family etc, and some of them are not things I am comfortable storing in skydrive...so that's not really an option. I've tried putting them directly into the folders using Windows Explorer on windows 8, and using Windows Phone Ap for Deskto and syncing through that interface. In both instances, everyting I put on the phone makes it there, and is viewable on the phone...until it randomly disappears. And it's not all of the files, but just most of them...particularly when the phone reboots.
In addition, I've had 3 or 4 times where the phone has randomly shut itself off.
So the question then, is this something that's a known thing with windows phone 8, or is this likely just a bug with the 1520, or perhaps just my phone in particular?

Sounds like an incompatible SD Card issue to me, despite the phone being advertised as being capable to be upgradable to 64GB, some SD Cards may not work and cause major issues like phone rebooting, files being deleted and other annoying issues. You can see if this is the case by simply removing the SD card and barrow a 32GB SD Card and see if you still experience these issues. You can also try leaving the SD Card out completely and see if the phone reboots itself during a test period without the SD Card.
I know this might put you off of continuing to use Windows Phone products (Android had never these SD Card issues on high end phones so long I can remember), but once you go Nokia Black (= firmware update of Nokia for WP8 phones), you'll never turn back, meaning there is more to WP then the eye can see (much smoother and more stable than lagdroid , although I myself find android 4.4 is improving, WP has the same smoothness on midbudget phones than Android high end phones even with cyanogenmod installed).

The only real issue I've had is the storage disappearing. The shutdown thing, and it's a shutdown, not a reboot, is annoying but wont' be a deal breaker.
I have a 32G SD I'll try and see if I have the same data retention issues. If I do, this phone is either going to be replaced with a new one, or I'm getting a note 3, depending on whatever anyone else has to say about this issue.
Thanks for the reply
*edit* - Changed the phone out yesterday. Seems to be holding photos and songs on the SD card, even through reboots. My journey to the dark side may be complete /nod
This is a strange one. I bought one of these a few weeks back:
http://www.amazon.com/Silicon-Power...&redirect=true&ref_=oh_aui_detailpage_o00_s00
It's been working fine for me. Yesterday, my tablet just hung. Like I could barely click on anything, and then when I could, it only seemed to last for a few seconds, and right back to totally hung. I had to force reboot my tablet, but it was not very long upon reboot that the same thing started.
I turned to google for advice, and one site recommended un-mounting my sd card. Well. yeah, doing that seems to have resolved the problem. It has been running completely fine ever since.
My question: Does this mean I have a bad SDcard, or is the problem with the tablet? Is there a way to know. I don't have the same problem when I plug this sd card into my windows computer.

Highly likely the sd card.
I bought one of those also and had the same problem. I returned it to Amazon for a refund.
Stick to decent cards like Samsung Evo.
Use cards which are U3 rated for fast writing.
I love marshmallow's adoptable storage feature, allowing me to install more apps. This feature worked beautifully for about a month and a half. However, I shut down the device, plugged it in to charge, went to sleep, and the next morning, the apps that were moved to the sd card were not available anymore. They were all greyed out on my launcher(Nova). I moved about 4 gigs worth of mostly games. Fortunately, most of them had cloud storage, but some favorite games didnt. This isn't that big of a problem, but I'd like to try to fix it. So, I went here for help.
At first, I thought the class 10 SanDisk 16gb sd had just gotten bumped out of the slot where the connections happen, so I opened the back cover and removed and inserted the sd card. The notification that prompted me to put the sd back in went away for a few seconds, but then came back. I repeated the process of removing and inserting the sd a few times, but still no moved apps were available. I put the sd into an adapter, then into my laptop, and it showed on file explorer. So the sd card could still be recognized, but maybe unusable.
I dont know what happened, one day it was working, the next day it wasn't. I know i formatted it as internal and portable storage a few times, so maybe that wore it out. I'm running cm13
Hello,
On my phone I used the micro SD card normally as external storage. On day I plugged in my headphones and there was no music. I though that the micro SD card must have come out. However, reinserted it it didn't work. I wouldn't open on computer either. While I don't have a solution, I am pretty sure I also had the same problem.
Once I was taking pictures with my phone when it crashed and rebooted. Some hours before the crash I uninstalled some apps and installed some others (but never rebooted the phone). After the phone started again after the crash, all the pictures and files were gone, the uninstalled apps were there as if I've never uninstalled them and the new installed ones dissapeared.

how long have you used your sd card? i'm sure that the more you use a micro sd card, the more it will wear out and become unuseable/corrupted. That has happened to me before, where the sd card just stopped working.

I have used it for about 1 year. So it may be that but, it has never occurred before.
Same problem here, you can read it here. While I am writing hopefully my files from Titanium Backup are transfered to my laptop. It got worse and worse, in my opinion the sd-card has reached it's end of life because of it's heavy usage. Error occured the first time after the phone got really hot recording gpx tracks. Bye bye sd-card
Another opinion is that warranty is over after two years, so the phone can quit it's duty now - obsolescense plans

yeah, i'm starting to think my micro sd just bailed from wear like that too, but i got to use mine for just over 3 months. i ejected the sd and put it into my computer, and interestingly enough, on my computer it reads 16 megabytes. i was like WAAT that cant be, i formatted it, put it back in my phone as portable, and it read as the normal 14gb. i'm starting to think my sd as internal is the cause of my random reboots. im even running the lastest cm13 update too...
i guess ill try and use my sd as just portable storage from now on, and see if i get any random reboots..
I switched to TurboROM which is using the sd-card as a portable media device, so no more encryption, heavy usage and complete data loss if you do not get your encryption key with root permission.
System space left after complete recovery of my apps with TB is quite nice - but you do not have the possibility to use App2SD (correct me if I am wrong).
So the only way to save internal system space is to move pictures, movies and heavy openstreetmap cards to external.
