Display thermal protection - RAZR HD Q&A, Help & Troubleshooting

In had my phone in the center console of the car, 4g going in and out, GPS on and I was using Google navigation. Noticed it getting hot and then I got a warning that the screen would dim for display thermal protection. It was to prevent burn in apparently.
I was only using it like this for maybe 20min. Yesterday I did the same but with 4g disabled.
Is this bad, should I be worried something is wrong with my phone?
ps car air con on so inside it was cool. Phone completely stock with Telstra (Aus)

Google navigation will make the phone feel pretty warm. Also if your 4g was coming in and out that is a cause too. When it is searching for signal constantly it gets very warm.

Possible deathgrip issue?

Ive noticed that 4g signal strength drops drastically when holding the phone normally in portrait mode.
Are u guys experiencing the same issue?

If I hold the phone by the top half with my hand cupped over the top, I can get it to lose reception. I doubt that will ever be an issue though.

If my hand covers the bottom of the phone (which is always when I hold it in portrait mode), then my signal drops significantly. Is this normal for this phone or is it an isolated defect?
I don't have any issues with that myself
I think you're on your own on this one OP.

+1 I reported this a while back. I also noticed that my Speck case which tightly holds the phone case seemed to cause signal problems...I've since removed the Speck.

i notice it sometimes. ive experienced that with some of my other devices. it only occurs here and there. havent had a dropped call one*knock on wood* and im expecting a case in the mail so that will solve the issue anyway.
This happens on many small phones where antennas are near the housing , depending where you hold it you'll affect the antenna's reception. For xeample, On the EVO if you hold the top half the 4G reception decreases, and the bottom half the wifi and cdma decreases
All of you, please research antenna attenuation.
This will happen in all phones where the antenna is near the surface. Signal does not travel through your hand as easy as it does air.
The iphone issue was more pronounced because the exterior antenna. Also, one could ground out the antenna completely by bridging the sections.
That is a deathgrip issue. Just a decrease in signal strength is an attenuation norm.
Although signal does seem to drops data speeds on this phone are faster than my mt4g even when my g2x shows lower signal so i guess its not rly a problem

This happens to me too. Especially in poor signal area. I would drop 3G/4G signal all together, and go to 2G.
+1 to this, I've noticed when I stick my phone in my boxer briefs that the reception does indeed drop down to nil
thank god for wifi calling though
For my phone I have 4G icon on screen and no bars, I can get call in my house finally.
It never ceases to amaze me how no matter what, there seems to always be some people that go out of their way to find something wrong with their phone. I really don't get it. Some people are probably better of with a Razr....

LOL !!!
update: I went to exchange my phone yesterday and it turns out that phone was just defective.
this new phone I have (although we went through like 3 and they all had backlight bleed) does not have signal drop when I hold it.
I believe the antenna is indeed on the bottom of the device. If you remove the back plate you'll see a sticker on the bottom of the phone. Try covering that sticker completely and you'll see your signal drop.
According to some people, after removing that sticker, they attained a slightly better and consistent signal.
Since removing it, I've noticed a much faster, better amd consistent connection, WAY better now. Hard to believe a silly sticker could cause so much trouble hahahaha

I had removed the sticker last night and I got 1 more bar and my dl/up speeds improved. Was getting Max 1.5 - 2 dl and 500 up now I get up to 10 megs down and 3 up in my house.

Cheap fix for WiFi Death Grip in Landscape

Go into your WiFi settings and hit the menu key. It will bring up an advanced settings menu. There is a box that you need to check. It's called "Best WiFi Performance". Once I checked this box, my WiFi signal stayed strong when holding it in Landscape. I tested this 2 rooms away from my router. I haven't noticed a decrease in battery performance either.
Nice, works well.

This might have helped... maybe. I said in the main thread about deathgrip I saw no change but maybe I was wrong. If it does help, it doesn't help a ton for me. This is easy for me to test at work where our wifi is not the greatest and it's easy to lose a signal. I still lose all bars with true deathgrip (which I would never use) but lose 1 or 2 bars while using it in my normal landscape mode. Pretty much the same thing I saw before turning on the boost but maybe I drop two bars less now. Too iffy for me to tell.
Wonder what the added power drain is by using this.
I'm wondering if an invisibleshield for the HTC Sensation will fix this problem, because I remember it did so with the iPhone 4. Hrmmm. Any thoughts?
this method doesnt seem to help my device at all... man, im sooo bummed about this issue....

did u notice any changes in battery life after using the boost?
Hitting walmart for a replacement. I thought I could handle the issue but I can't and its unacceptable. And this time, I'm checking for EVERY possible bug that has been found before I exchange it. Only bummer is that I put a screen protector on the sensation I have now. I have to use the last screen protector now

The problem with the iphone 4 was that your finger would bridge the gap between the 2 antenna and ground it, thus reducing the signal.
The problem with the sensation is your hand is blocking the antenna, so adding a case/cover may actually block even more signal.
This only helps a tiny bit.
I've tried this option, not to fix the "death grip", but to improve overall WiFi performance, and it seemed to drain my battery quicker than normal. Also didn't seem to really help.

Doesn't help. I still lose 1-2 bars in landscape. Oh, and you can also try putting alu foil between the contacts of the cover and the phone (that didn't work for me either, but it did for someone else)

My WiFi is absolutely terrible. I have a case on, and if I put my sensation face up on my wooden table, the wifi will die. If I put my hand anywhere near the upper-back, such as in landscape mode, the WiFi dies. This is with Wifi on best performance and when I normal get 2-3 bars of service.
Also, my wifi constantly cuts out even if I leave it in a position that should have signal. For example, in the 2 minutes I took to write this post, I turned wifi on and placed the phone face down on the table. This should be the best way to keep the signal. One minute later, I checked the phone, and the wifi was dead. This basically makes wifi calling absolutely useless.
I'm really beginning to get pissed of because of this. This isn't a death grip issue. This is just a plain utterly crappy wifi signal issue.
thanks for this, it did help a bit.

Get a new back cover from HTC (they give one for free under the warranty), but don't mention the WiFi problems. Just tell them it's loose or something. Here's the number.

This.
If you use an app like wifi analyzer and you toggle the option you can see what it's doing is sending more power to the wifi antenna/chip. Your signal is stronger with it on but it definitely makes the battery drain faster, it did for me so I leave it turned off.
It even says in the option that it will decrease battery life. Can't get clearer than that.

Especially after the update this option actually cause a huge battery drain and it doesn't improve performance much.

Alright, have a new battery cover coming in. Let's hope this one works better. Does the battery cover really have much of an effect on signals though? I don't see how it could without a redesign...

Death Grip and wireless mode.

So, I've been afflicted with the death grip issue at home something fierce. If I hold the phone in landscape mode as if I were to type with my thumbs, the wifi cuts out. It doesn't seem to matter how close I am to the wifi router or if I turn on Wi-Fi best performance. At home, the network is configured to use 802.11g for compatibility with some older devices.
At work, I run an 802.11n network (I'm the IT Director). While I've got much better access points and better line of sight, I have similar sorts of distances. With 802.11n the death grip issue seems less significant. The network never drops out completely (I lose maybe a bar) although network *traffic* seems to stall to a degree. This is true even if I go into other rooms where I don't have great line of sight.
I'm still doing some surreptitious testing (since I have work to do, too) but I thought I'd ask the rest of you if you're having seriously issues with the death grip, what mode is your wifi in? 802.11g or 802.11n?
I really haven't had this problem, when I hold it in landscape it goes down 1 bar but comes right back,I'm starting to think its device related ,just like the HD2 some of them had wi-fi issues and it was just the hardware couldn't do nothing about it but exchange the device
I used to have this issue until I changed the wifi performance to maximum and out a gel skin case on. Now mine doesn't even drop a bar from 2 rooms away.

Thank you
I would notice the signal go down when I held it in landscape but it never dropped completely but last night I got the real effect of it. I was streaming a movie from my computer and viewing it on my sensation using splash top (only about 15-20 feet away from the roiter) Everytime I held the sensation and touched the "death grip" spot my video would stutter.. Tried setting the wifi to max performance and I have the tmo gel case on.
I guess one difference between this and the Iphone antenna-gate is that if HTC does consider it a problem and does fix it, they only have to replace the back cover and not the whole phone
I heard someone said foil on the outside helps out the issue, but it looks really ugly. Wonder if we can come up with a fix that can be done on the inside of the cover. Maybe attach more wiring to the connections or something..
Wonder if those cheap cell phone singal booster on the inside cover would help out at all.. hey if foil did then maybe one of the will shrugs
I just have to say I don't think this "death grip" is a hardware issue .... I think it is a software issue. I had a g2 and flashed cyanogen ... Worst WiFi reception ever. Went for a more stock based Rom and bingo! Also I noticed if you turn off mobile networks from the task bar and turn on WiFi, you will have superb WiFi...
On the sensation of course. Lol

Trying to Figure out the Wifi-Death Grip Issue
Something Odd happened to me, i wanted to share with the rest of the comments here because i have not been impressed with my Sensation's performance so far. I have had the normal low volume and the erratic sense speeds along with what Phil showed when trying to use the carousel, but nothing was more annoying as with the wifi issue. I got it five feet from my router and i have two routers and one is open and one has PS2K. I tried it with and without the cover and behold i lost my signal when i held it in landscape or put it lying flat. I decided i needed to go to a T-mobile and complain about it, but while i was waiting to be attended, i went ahead and started playing with the sensation they had on display. To my surprise i could not duplicate the issue at all, I checked their version and went to the advanced setting under wifi and it was no put on maximum performance. I pulled out mine and as you could imagine, i could not duplicate the issue anymore. I was puzzled because although i lost some bars, it remained connected and i did not lose the signal completely or as easily when i was at home. I decided not to look like a fool and when across the street to a Best-Buy, and logged onto their open network and had no issue again i tried to put the death grip on it, put it in landscape or lay it flat on it's back and although i was looking some bars, i could not duplicate what was going on at my house. I went back home and reset my routers and the issue is still there. So from what i can tell, i think we may need to find out if this issue is with some routers only or with the encryption used.
FYI: I have a N1, IPad2, HD2, MY3G and don't have any wifi or death grip issues with any one of them so i am seriously leaning to a software issue.
Whatever, the issue i can see Why Phil and a lot others do not see this issue and i can understand why a lot of us are experiencing the issue. Hope something is found out soon.
Routers i use:
DLink (DIR 601) Open network
Ambit WPA2-PSK
(i have tried changing channels and updating firmware on both routers)

[Q] battery gets hot even in normal use

Hey folks,
I habe a small question. Ive bought a htc 7 pro yesterday and i noticed that my phone gets Hot, even when i only surf a Little Bit in the Internet or if i leave IT in standby.
I can feel it through my back Cover and im not to Sure if its normal.
I hope you can give me advice wether to Return the phone or leave it as it is.
Greetings Tekkpriest.
PS. Please be gentle about this written english i havemt configured the grammar and stuff yet
are u using the cellular connection or WiFi? or are u in a poor signal area? I find that my arrive does this when I use the cellular connection,its because the cell towers for my área are still weak so the phone has to work harder to hold the signal which causes the heat generation, it also feels hot because the cover is metal and metal conducts heat.
I've noticed that my battery can get hot sometimes too, but normally only after playing games for a while.
I noticed my battery gets really hot too sometimes. It was so hot I had to put it down.
I've had windows phones since the wizard and none have gotten this hot though my tp1 would get almost as hot if I was tethering (downloading) and running multiple things.

Device getting hot when navigating

Is anyone else experiencing the lower part of the device getting hot when using navigation?
Don't worry. It's normal. Sensation is getting hot when is heavily used.
Mine too, gets very hot, front and back where the unlock ring sits.
The bizarre thing is, it keeps staying hot, or even hotter, even when I have finished and its resting.
Sometimes its a bit uncomfortable to hold,hope it doesnt die on me!
mine is also like that.

Try plugging your phone into your car charger, turning GPS on, co pilot on, with Bluetooth sending music to your car stereo and go for a 200 mile drive like I did the other week, I could've cooked eggs on the damn thing, however the heat is normal and nothing broke, I think.

It's normal across the board for the phone, but that doesn't mean it's ok. I think the phone tends to run way too hot for a passively cooled device. It may be attributed to a battery or even software issue.
I have found if you are not using the data for high speed data. P ut my phone on 2g "GSM only" My phone runs cool and battery lasts all day. Plus you still get all your sync.
This is under settings -- wireless -- mobile networks -- network mode -- set to gsm only.
Works great.. When you are going to be doing heavy data put it on auto.
It's quite normal. I had the same scenario while using GPS with car charger plugged in on my Nexus One, G2X and Sensation....

HI
I would do that if there was any App available for Toggle between 2G and 4G connection , so i dont have to go to setting every time to change between 2G and 4G.
Thanks
