650D Stalls/freezes with solid red light

My new 650D sometimes stalls/freezes for long periods and the only way around it is to take out the battery or SD card and re-insert. This is extremely frustrating. The camera also does not save all photos taken. After a session of about 50 photos, only about 6-10 photos is on the SD card (Transcend 32GB Class 10). What do I do wrong or should I take it back to the dealer? I'm about to throw this thing against the wall....

I don't own your camera, but I would try a few things before smashing the camera.

First:
Format the card IN THE CAMERA.

Second:
Try a different card. I prefer SANDISK, also use Patriot. I have never had a card issue.

Third:
Download and re-install (even if it is the same version) the latest firmware directly from Canon. Use the newer (not Transcend) SD card.

Thanx for the reply. I just did a firmware update and I did do a format of the card when I installed it the first time. I will see how it works from now on, and if the problem persists, I will switch to another card...

Good luck. I don't know for sure, but I doubt if it is the camera itself. The camera knows how to throw errors when something internal isn't right.

Counterfeit cards are quite common in the marketplace; Amazon even has a section on counterfeit cards. Some cards are "genuine" but people relabel a $2 class 4 card as class 10 and then the camera acts up. Where did you get the card you are using? Was it a reputable source?

It is actually the Transcend WiFi SD 32Gb card. Yes the source is reputable. The wifi functionality of the card works extremely well. The card is listed as compatible with the 650D.

You're probbaly just filling the buffer and the camera is writing the images to the card.

What "lomdel" experienced is a typical card error. I have one Sandisk card that plays up the same way. I bought it in Hong Kong Airport and it started playing up travelling in EU. So in the end had to throw it out. Reformatting did not help.

By any chance, are you taking very long exposures? And do you have Long Exposure Noise Reduction enabled?

If so, to perform LENR the camera takes a second shot, the same length of time as the first, with the shutter closed. This is used to identify noise to be deducted from the initial long exposure.

In other words, if you have LENR turned on and take a 30 second exposure, the camera will automatically take a second 30 second exposure... the "blank" shot with shutter closed... so it will take a full minute.

While the camera is making the second exposure, it's busy and unusable. Since the shutter is closed, you can move the camera around during the second exposure without concern. If you turn off the camera or pull out the battery, that will cancel the second exposure, and both images will be discarded.

Or it could be that your memory card is slow writing. I don't use any WiFi cards, or many SD for that matter. So I'm not sure how they are rated. But, for example, I know that some older Compact Flash cards made by Dane Electric I almost bought were rated "300X", but that was misleading. I saw them advertised at a great price, but some research online uncovered that 300X (45MB/sec) was only their download or "read" speed... it was not their "write" speed. They tested to have an actual write speed around 75X (around 13MB sec), so really would have slowed down my cameras, especially when I was shooting fast or using continuous shooting mode.

I am not aware of any similar problems with Transcend memory cards. But, who knows! Maybe you could find some specific test info for your cards online.

@amfoto1. I am not taking any long exposures. My camera is usually on either the green "Auto" setting or the Portrait, Landscape or Sports settings on the dial. I do not know enough about photography to delve into custom settings. However, a firmware update seemed to have resolved all the issues I had with the camera. It responds quicker, is consistent and reliable and even the Wi-Fi functionality of the Transcend Wifi card seems to respond better now.

Good news, sounds like a little glitch in the software.
