This ring fell out recently on my Sensation too but I realized it and put it back in.
Does anyone know how I can fix this?
Was the ring put in some kind of clamps which broke or was it just bad glue that needs to be replaced now?

Just glue it. Won't really ruin anything. But just be careful not to glue the lens. As for replacement. I tried checking eBay, etc for ya but couldnt find any. I think what you can do is buy a new housing/battery cover. They cost about $26-30 on eBay.

Sent from my HTC Sensation XE with Beats Audio using XDA

Does this ring also have glass, or is it just a ring?

The housing/ backcover on all4celluar dot com is only 17 bucks. The stock one not the white.

My sensation xe back cover had became loose over time. I emailed HTC about this and within 2 weeks they sent me a new one out free of charge. You might want to look into this

Do you have to send in your whole phone, give them your serial number, or sen pictures of the phone?

My phones warranty is already voided through software (S-off) and hardware (void seal broken) :P

all they wanted from me was name, adress and proof of purchase (i sent them a picture of my phones4u contract). I didn't have to send phone or anything away.

I would also recommend this solution, i'v had very good experience with HTC when I had problems with my desire battery swelling (probably because of using high power led flash too often). They only asked for a copy of the receipt and the shipping address.
