Xperia Z loses and doesn't recognize SD card

[Jeka21rus]

Sometimes while using camera (taking several photo) phone loses SD card and doesn't recognize it. Sometimes it can be solved by restarting phone (power off, wait a couple minutes, power on), removing and inserting SD card, and other geek methods. Last time phone lost SD and these actions didn't bring any result. However, phone see SD for now, but offers to format memory card while my PC opens it without any problem via card reader.

I'm using Transcend Ultimate 32 GB (class 10) memory card. Do I have to try using any other vendors? And is it a software problem or I have to bring my phone to service center?

Upd: Transcend SD become dead, I bought Sandisk Ultra 32 GB, and sometimes I see this problem with new one.

No luck for me

on another thread here someone reported that sandisk cards are thinner than other makes and could cause a marginal connection in the phone - this would  support the symptoms you are having, the solution seems to be to build up a layer of tape on the (none contact side) upper side of the card to increase the thikness slightly , sounds very plausible

read this linky - not just 64gb cards and not just experia Z but you will see post 86 in middle a possible explanation and solution

No, two layers of tape didn't help me

Going to try the next layer

At last third layer of tape doesn't help

Also users who had problems with SD say that formatting SD to exFAT file system (and using it on rooted phone) solve problem (card self-unmounting while copying many huge files at one time, opening camera with caching pictures, etc) absolutely.

Meanwhile.. 8 months went through, but my problem is on the way (SXZ .67 FW, Sandisk Ultra 32 GB, ExFAT)..
Sandisk 32 is being thrown out sometimes.
Today I bought Sony SR-32UYA SD card - so I will be watching it. I'm too tired to proof the problem, if it will be seen, I will change my phone for other vendor

UPD: It seems that happiness came to me. I performed high load testing - it works without any breaks

Updated my phone yesterday & since then i've been getting messages saying 'mem card unexpectedy removed' & similar messages & now neither my phone nor pc recognises the memory card. Surely it's not coincidence so many people having same issue. Xperia Z San Disc 32GB mem card Class 4. I contacted Sony but they're blaming the memory card which was new when bought 4 months ago just after i got my phone. I can't believe Sony are dismissing this so lightly but i'm sure people will reflect their disapproval when choosing their new handset.

Me too but i used micro sd kingston 32 gb,, my sd card dead..lost my memory data..

I bought a 64gb SanDisk Micro SD about 5 months ago and it has worked fine in my Xz ever since. Until, like 3 days ago.... The camera first reported memory problem, then Google Play Music started refusing to download due to lack of space, next was the Pc was unable to write to it. The latest update has broken something and Sony think it's SanDisks fault... Why? It works fine in an Acer A500 tablet and my MK809ii

I have errors recently about my SD card being faulty. As I have not seen this before and do not usually touch the SD card I ignored it and turned the phone off an on. It appears to be OK and I can see the SD card listed in File Commander where as before it was not listed. I guess this is a bug?
