RAZR HD loses microSD connection. Also battery issues. ** Probably SanDisk problem **

[Eug]

This is pretty irritating. Lately my RAZR HD has been losing the connection to my SanDisk Ultra 32 GB microSDHC card. Every so often it gives me a yield sign icon saying the card was unexpectedly disconnected, and sometimes it says it's preparing the card. Luckily I have nothing important on it, but this effectively makes the card useless.

I've also have some power issues. Once in a while I'll have say half of the power present when I go to bed, and then when I get up it's completely drained.

I'm thinking it's one of two problems. 1) The above card issue or 2) IP Camera Viewer Pro.

Anything I can do about this? Particularly about the microSD card? Could the microSD card issue be a power issue? It works fine on my iMac. Do fast 32 GB cards draw significantly more power than say cheap slow 8 GB cards?

I'm on Jelly Bean 4.1 BTW, stock Fido firmware (which is almost devoid of carrier bloatware, aside from their crappy Visual Voicemail Plus application and a couple of other apps).

EDIT:

There is a manufacturing issue with some SanDisk 32 GB and 64 GB microSD cards:

I would get rid of that app you listed, reboot and see what happens before you go to bed again. A rogue app can tear a battery up easily

You sure its not the microSD card. I had the same exact problem with my old HTC Incredible and a new microSD card solved it (even though the bum microSD card still seemed to work in a few other devices).

Well, the card works perfectly on my computers, but your point is taken. Now I see microSD issues plague the Samsung Galaxy S III as well, and it seems to be more common with SanDisk. (Not much out there in internet land about the RAZR HD.) I wonder if it's more of a compatibility issue.

As for deleting the IP Camera Viewer Pro app, I can't do that. It's what I use for my babycam. I had purchased tinyCam Monitor Pro before, but it is unstable with my IP camera. It may lockup after an hour.

However, I did force quit IP Camera View Pro a couple of nights before I went to bed, and the phone didn't lose significant power overnight, but then again on those nights the microSD card didn't dismount either. I'm reading from the GS3 threads that the repeated dismounts and remounts can eat up power.

I'll run the phone without the microSD card at all for a few days to see what happens. I only had MKV on there, but the times I want MKV I prefer my Nexus 7 anyway, so no big loss.

Well, here we go:

SanDisk has been made aware of potential product issues involving a very small percentage of its 32GB and 64GB SanDisk Mobile Ultra microSD cards. Under certain circumstances the cards may lock up and the card becomes inaccessible. The issue has been identified and a manufacturing fix has already been put in place. SanDisk stands behind its products and any customer who experiences this issue with the microSD cards cards is asked to contact the SanDisk support center for a resolution immediately.

Mine isn't the "Mobile Ultra" but the "Ultra", but I'm thinking it may be the same thing.

EDIT:

It seems microSD cards labelled "Ultra" may be "Mobile Ultra".

Ooo that is scary as I was just about to buy the 64GB version.

Eug, I was having problems with the SD card in my Razr HD being unexpectedly disconnected, but it was the tray door not sitting flush with the side of the phone. It was causing the card to disconnect and reconnect whenever I pushed on the tray. I eventually just took out the sd card altogether because there was 32GB internal.

The tray door was flush, as far as I could tell. And the card was properly clicked in. It was working fine too up until recently, and I haven't touched the tray since long before the card started acting up.

In any case, all SanDisk said to do was to reformat the card on the computer and test again. If it continues the unusual behaviour then it may mean an RMA.

I would invest in a Samsung microSD, preferably their highest end UHS-1 cards.

Seriously, I cannot stress enough just how important it is to get the very best microSD you can for phones.
