Display showing only colored dots

Since yesterday my HTC Sensation shows only a screen with colored dots - it seems to be some kind of physical problem, as removing the battery and rebooting does not help. Has anybody experienced such problems in the past or has a clue what's wrong with it?

Are u able to get into hboot?Recovery? Have you connected to PC and tried adb devices?Or tried to flash an ruu? Are you on stock or rooted rom.

Can't get into hboot or recovery on the handset (screen stays black).
But seems that I can get into recovery over adb pressing volume down and turning on with a PC connected.
adb devices

I don't think so, actually I believe I've always been good to my phone. Can't even remember it falling down once and should also not have been in contact with water. That's why I'm posting here, I was mainly interested if anybody has seen such problems in the past (and especially if he/she knows a reason for them).
It practically happened all of a sudden - well, actually I had the problem already for two or three times about one month ago, but at that time only for a second, not reproducible (first even thought about a software problem). Now it suddenly changed to a constant problem.

Mine was actually repaired as warranty repair (they replaced mainboard/display).

Had they flashed your phone after fix?

Anyone else having these problems?

First off I would like to say I love the phone EXCEPT for these two major problems. First one....I will pull the phone out of my pocket and it will have put itself into airplane mode. It will cut the bluetoooth on and sometimes cut the location off. I have had it where the screen is on when I pull it out of my pocket and sometimes it will still be locked and this happens. Today it cut the flashlight on and the screen was still locked. I use a pin code for my lock screen. Second and the major one is dropped calls. I have probably made 13 calls and 7 have dropped. On one of them it dropped 3 times on the same person. Sometimes when I pull the phone away from my face after a dropped call or a successful call, the notification bar will be pulled down. Its like the proximity sensor isn't working. I use cricket and have had none of these problems on my S6. I guess when I get time tomorrow I'm going to factory reset but I was just wondering if anyone else was having these problems? Maybe I got a dud.

Maybe your issue is related to mine.
Press the top left of your phone, right next to the power button, a bit hard. Does it make it go on/off? If so, maybe the force when it's in your pants is causing it to turn on and do random functions.

Yes and it didn't make it come on or off. Going to try a factory rest.

Well, did the reset work??

I haven't had time yet. I'm going to try it possible tonight or tomorrow morning when I have more time.

Just did a factory reset. I will find out in the next couple of days if it worked. Will post results. Hope it does. Like it as much as my S6.....except the camera. The camera isn't bad but the S6 is great.

does the factory reset default back to the original out of box software or does it default to the latest version?

It's going to reset to the last ROM that was installed on the phone. Once you update the phone you can't go back. Well you can but you need a custom recovery and the original ROM to flash.

I did the factory reset and seemed to help my problem. No pocket weirdness and calls seem to be fine. Will give it a few more days and post results.

Dropped call
I agree with your second issues: dropped calls.
Even i'm facing the same issue. More than 10 calls were dropped in a day, did factory reset - worked fine for 2-3 days and same issues appeared.
it seems to me something with signal issues.
One of the post in another thread points out the signal issues with the phone.

I'm not having any dropped calls so far but the dialer is still a bit weird. No random airplane mode or anything else while in my pocket though.

im running cricket but i havent noticed any droppped calls or maybe its just i dont talk much lol oh btw some text messages take a bit to send

Not sure if it makes a difference but I use Nova Launcher as my launcher and Rocketdialer as my dialer....and I'm getting normal behavior. The signal is slightly weaker than my nexus 4 was giving me in wcdma mode but that's the only quirk I've noticed.

2nd Screen not showing with main off but shortcuts still active

Just got the phone ,stock att, I already did factory reset it doesn't show 2nd screen when main off but the shortcuts still work(flashlight camera etc..). Could it be that it is super dim, anyway to change that ? It works normal with main screen on. I am on latest att update. I looked everywhere and didn't see anyone with similar issue that didn't get fixed by factory reset. Phone is unlocked also. Any ideas ?

Could you give a little more information about your problem?
The phone has a sensor that detects when you have a flip cover on and shuts off the second screen until you open it, so it could be there's something in front of it.
Another thing you can try is disabling Quick Cover in the settings if you don't have the official LG cover.

I tested that sensor with aida64 it seems to be working fine when I put my hand in front of it, also it doesn't show anything in front of it otherwise. I disabled the quick cover option and enabled it doesn't work either way. One thing I noticed that if I use quick cover case and open and close really fast I can see the 2nd screen being on for split second and then it goes black even though the shortcuts are still there.

Ok. One last thing you should try is to go into settings, Second Screen, and toggle the two options in there. One should be for when the main screen is on, another for when it is off. Switch both of them off, then on, and restart the phone. If that doesn't work, perhaps there's something wrong with the screen.

Could you post an example of what exactly is happening? The second screen does have some issues, mainly light bleed, but that's something that is inevitable due to the manufacturing process. It could be a problem with the backlight, because as far as I know, the screens are independent and don't utilize the same backlight.

I see now. Does the signature show up or do neither of the options work?
I am not sure, but you could also try manually setting your clock and weather settings as well. It is definitely something software side.

Neither option work. Though like I said even though screen is dark if I swipe it to the left with main screen off the shortcuts do work. I want to think this is software issue, but then factory reset should have fixed it. With smart cover it will stay on for half a second and then go dark.

Believe me, factory resetting a phone can fix many issues, but if 8ts a bug in the ROM itself, it won't fix that. It is a very strange issue, I admit. I don't know if the phone has a separate backlight for ambient display, but if the screen works when the device is unlocked, it should work when it is off.
My best recommendation for you is to exchange the phone if still under warranty. If you cannot do that, then perhaps try flashing another stock AT&T Rom. If you are unable to do that, then your best bet is to keep fiddling with settings to see if it gets fixed or not.

I did buy it on swappa. I do have the receipt from the person that bought it at att store (it was bought in december last year) however I am on cricket. I doubt att will help me. I may need to send it to LG as last resort. I was just hoping there is something else I can do. Could you point to a good guide regarding flashing a stock rom ? I haven't flashed anything in a while

I used this guide a quite some time ago when I was removing a rooted FW. I hope this can help.

I sent the phone to LG and they "repaired" it. They friggin replaced the lcd and obviously didn't test for the issue. It is still there. Question is should I return it again or should I try flashing it myself ?

Well, I flashed latest stock firmware using LGUP refurbish option and it didn't fix it. Does anyone have any other ideas ?

Well, I can tell you from experience that whomever received your device for repair probably didn't get all the information. He or she was probably told that there were issues with the screen and to just replace it, without anything else. This is what happens when you have a third party that doesn't understand much about the technology or the devices themselves transferring information between two points.
I can honestly tell you that if swapping out the display didn't fix your issue, there's not much to do about it. It's a shame though, because this is a great phone, and besides battery life, LG nailed pretty much every aspect of what a great phone is. I think your best best is to contact the original owner and notify them of the issue and work something out. Other than that, you can either keep using the device like it or switch to another phone.

No screen rotation gyroscope and accelerometer stuck on SM-G900P

Hello, I have Samsung galaxy s5 G900P with stock rom 5.0 .
I have noticed that the rotation doesn't work even if I activate auto rotation or not , When I test my sensors with this code *#0*# I found that the gyroscope and the accelerometer stuck and the test fails .
I used the safe mode but no difference.
Please help.

I had the same issue. From what I know, if the test fails, your hardware for it went bad. I have to use a rotation app to go landscape. I just deal. Until I get a new phone. There's really only a couple apps it's annoying for, at least in my case. Not being able to track my steps doesn't really bother me. I know if I'm walking enough without a device needing to tell me.

Touch Isn't working *Screen NOT cracked*

Hello, so i had my OnePlus one for a while and just recently i dropped it lucky the screen didn't crack and opens up just fine but the touch stopped working is there a fix for this? And how do i go about it.. I'm currently in Egypt so there isn't really any replacements and anyone who knows much about this device to be able to repair it at a decent price. I would like to fix it on my own, and i honestly hope its just a wire unplugged or something..
Thanks.

If you're screen stopped working after dropping it, it is most likely damaged. Dropping it will not cause any rom to malfunction and stop touch from working. It may be a loose connection, or if you got the device used from somewhere, the screen may have once been replaced and the replacement may not be as good as the original (which by no means was perfect either).

It happened to me. Open your opo, disconnect and then reconnect the screen.
