Backlight sometimes doesn't turn on when unlocking?

Has anyone else had this with their G Pad?
When you knock on, or use the power button, the screen will turn on (you can see the lockscreen, unlock and run things etc) but the backlight looks to be extremely dim or not on at all! Locking and unlocking brings it back to normal, and there's no issues using the device at all after this, just this random occurrence occasionally. When I say occasionally, if I was to lock and unlock constantly to test the issue, it'll happen maybe once every 10 tries. So far I've only noticed it when I go to unlock it after being locked for 30+ minutes.
I know there are bleeding issues and blue line issues and the likes, but I've not seen this one before. Just don't fancy it being a duff unit!

I have a similar issue... With my device this only happens if I try to turn it on immediately after the screen goes off. It seems to me more ROM related than a hardware issue, but I can't say for sure.

Yeah, the more I see it the more I think it may be software related, but reluctant to do a restore on the tab in-case it's a wasted venture. I still can't find anything online, but mine is defiantly more likely to do it after longer periods of time. Had it three times in a row yesterday morning!

I have had this since day 1. Though I have also been custom romming since day 1. I can't remember if this happened on stock. But would love to know if these units are defective or if everyone get this.

stock rom same behaviour
Hi just in case someone is still wondering, i have a stock g pad and it shows the same behaviour... sometimes (especially right after locking) when i unlock the backlight doesn't come on. Locking again and unlocking works in this case.

Same here, was happening on stock and it's the same issue on Mahdi rom now.

Mine is the same, did you ever resolve this issue?

Unfortunately not! I've got rid of the G Pad now (barely used it after a time. ) but after getting a IVSO cover for it which locked/unlocked the tab for me, I rarely saw it! I turned the pin/swipe lock screen off too as it was a faff to open the case and then unlock the tab, so maybe turning security off did it.

Thanks for the reply I have a feeling its a ROM issue. Mine did it yesterday so I tried an experiment and stuck it on charge and it instantly went to normal brightness. If it was a hardware fault I would have thought it wouldn't alter no matter what.

[Q] Mic not working as should

Hi,
My microphone is not working as it should on the M8 when I get a call or call someone. I can hear them, they can't hear me. Sometimes it works as it should, but it happens more and more infrequent. If I turn on the speaker, the mic seems to work just fine. Isn't it the same mic? I've tried to flash a new ROM (ARHD), and it worked the first two calls, then I didn't try it for a few hours. The next call, it didn't work. Tried to factory reset it, still nothing.
This happend suddenly when I was on a vacation. I didn't flash anything or do anything (that I'm aware of) to trigger this issue. Is there another modem/radio released I can try? The only one I found, was the stock one I already used.
Any ideas?

I had the same exact issue that you were having. It just happened randomly. The only option is to get a replacement phone. If you are on AT&T )i know for sure), they will cross ship you a new phone to replace yours.

Thanks, I'll return it to stock and test one more time. If it still fails, I'll try to get a replacment.

Ended up sending it in for repair. They repaired it on Waranty, sent it back with a scratch in the display. Sent it back again.. Haven't gotten it back yet (they're sloow), but seems this is a hardware issue.

HTC one m8 mic goes kaput
Hello guys,
I haven't been here for a while now. That's because I was still using my old SGS and experimenting CM on it. Nothing special, but now that SGS has become too slow and USB connection to PC wouldn't work. I bought an HTC one M8 last week, and guess what the mic wouldn't work. Same issue that is mentioned here. I tried blowing of the dust with an LP blower, resets and everything I can but it wouldn't work. I ran an HTC hardware test and in the audio test the main mic was not working though the 2nd mic seems to be fine.
Reading up all the user problems from various sites, I conclude that sending the phone back to service center is the only option. It's really sad as my phone is just a week old and I started liking it. I still like it but come on HTC one year down and you couldn't still resolve the issue. Apparently many have the same problem hence that is pain divided.
Cheers guys!!!
Edit : HTC hardware test code *#*#3424#*#* (if it helps someone)

How much is "many" (with the same problem)? Its deceiving to try to get a sense of how common an particular issue is, just by searching around the internet. Folks will usually only take to the internet when there is a problem; and this doesn't account for the thousands that don't have this issue (tends to blow the issue out of proportion). Can't speak for other websites, but I haven't seen this issue on XDA much at all for the M8. Every manufacturer has defects out of the box. Its the exact number or % defects that they often keep secret. You can't judge a manufacturer on one single defective device, its often just a matter of bad luck. Get a replacement and give it a chance, before you pass judgement.

Too "many" . Links that I read are here, here and here.
I agree with you that every manufacturer has defect, but this defect should have been sorted by HTC by now I believe. Don't get me wrong, I love the phone, it's amazing. But the primary use a phone is calling and that went wrong in a week made me a bit excited.
Cheers!

Going through those post, I see there are actually only around 8 individual folks reporting the problem on the M8 specifically. Some of the remaining complaints refer to the M7, which while HTC, is a completely different phone; so not really applicable IMO. And a few saying they have the same problem, but don't specify which phone they are talking about.
As I mentioned before, this is out of the thousands of M8's that have been sold. Sure, there are likely a good number of folks out there with the microphone issue, that haven't posted on any forums. But thousand and thousands more whose M8's work just fine, but not many folks take to the internet to post that "everything works as it should". Like I said, the internet can give you a distorted image of how serious or common an issue really is.
Not trying to start a fight, just making a point. I can sympathize with the frustration of having a expensive, brand new shiny phone not working correctly. But its likely just bad luck; and with any product, I'd recommend to give the vendor at least the chance to make it good before you conclude the entire company is crap. Not sure where you purchased from (store, carrier, etc.), country, and the exchange policy. But many vendors will replace with a brand new handset when the phone has been found to have a defect so soon as in your case.

Definitely mate, I get your point. No offense, I like the phone, but as you said, it is my frustration talking.
I will update here on the service and the happenings thereafter.
One good thing is my SGS got a new rom since HTC is back in the box.

Mic not working in HTC one M8
Hey All,
I had returned my phone to my suppliers and they returned it a week later telling me they repaired the issue. But after using it for 10 days, the mic wouldn't work again. I returned it again to the suppliers hoping that they would give me a replacement but they inform me today that they have repaired it now and they are sending it back. I will update again once I start using the phone.
Cheers!

I have the exact same strange problem with my M8 DualSim phone.
When i talk to people the first 2-3 sec is working fine, but then all they hear is static noice.
When i switch to loudspeaker on my phone, the microphone seems to Work fine thoug.
- i thought that there was only one microphone in the M8 ?
I have tried to power off and restart the phone, but that didn´t help at all..
My phone is on the latest 4.4.4 from HTC, it have never been rooted and never had any odd firmware loaded.
It seems like i have to send my 3 months phone old in for repair :crying:
UPDATE: Arter a few hours or sometimes days, the mic start working again...?
Actually i have two times now decided to send in the phone for repair, only to discover that it works again soon after...
But now i send it in nomatter what...?

It just happened to my M8 running digitalhigh's GPE 4.4.4 rom. This has got to be a software problem because first I couldn't hear the caller, then after a reboot, they couldn't hear me. So I used Skype and both the mic and earpiece work fine. Go figure.

i had the same problem too. What i did is just heating the bottom of the phone with hair dryer. And it is working well now.

Fixed
Hi all: I was having the same problem as everyone. Except sending my phone back was not an option—out of warranty. I fixed it by replacing two lines of code in the mixer_paths.xml file. I got the idea from this thread http://forum.xda-developers.com/one...google-low-t2805568/post53914918#post53914918
Towards the bottom of the file, I copy and pasted "main-mic" with "2nd-mic" and vice versa. That's it. Two copy and pastes, and I let the file references take care of the rest. Now my phone uses the 2nd mic as the main voice mic and people on the other end can hear me just fine.

I am on htc one e8 out of warranty which also has two mics. I dont know where is main mic but i see the secondary noise cancelation mic near rear camera lens. I run the htc hardware test with code and findout that my main mic dont work but secondary is fine. Can i try thiz on htc one e8 as they two are very similar
Also what did you change. Did you just replaced the name "main-mic" with "2nd-mic" or you replaced the texts underneath "main-mic" with texts uunderneath "2nd-mic"

[Q] Note 2 will not turn on / charge

Hi guys,
Super confused here. I accidentally left my Note 2 on during a movie and it drained to 0%/shut off. I then charged it when i got home and fell asleep while texting someone. Everything seemed fine til i woke up and realized my phone was off. It was pretty warm to the touch and wouldnt turn on at all...never had that problem before. Tried to hard reset and whatnot with no success...
It also will not charge (no notification screen, LED not lighting up) but will get warm pretty quickly when plugged in.
I'm seriously clueless here....Any help would be appreciated!
Note 2 on Telus (canada) and rooted about a year ago. Phone itself is 1.5 years old
Thanks,
Daniel

Can you get to recovery or download mode and try to restore backups?

Oi, eu tenho um N7100 e ele também não recarregava quando a bateria chegava a zero. Meu irmão também tem um N7100, e tudo que fiz foi carregar minha bateria no celular dele. Pode não ser uma solução definitiva, mas depois que conseguir carregar sua bateria em outro celular, ou carregar sua bateria em um carregador universal de baterias, não deixe que ele chegue a 0% novamente. Espero que tenha ajudado. Abraços.

happen once before, end up changing to new battery and problem fixed:laugh:

I had the exact same problem only a few days ago. Phone shut itself off and wouldn't turn on again, no recovery no nothing. Problem persisted even with my secondary battery.
I then sent it to Samsung support because it still had warranty left.
Of course they refused to repair it because it has CM installed which I obviously was unable to remove prior to sending it in. HOWEVER to check whether it was rooted or not they somehow revived the phone and it is fully functional ever since.
I don't know if this could be any help to you, but I hope it is.

Random (and ghostly) touches on screen

Hi guys!
I have a F180L (converted on a E975), my phone never fell from any distance, or had any kind of impact, BUT...Since I updated to last version o Carbom ROM, I've got a issue on my screen...
There are random touches on my down-left corner of the screen. It's completely random, while the charger is plugged, or not. But it only happens when an app is opened, while in homescreen (even on google now cards) everything is ok...
I've already flashed another rom, the AOKP Android L release 11, the problem still here...I installed a screen tester app, and this corner is not recognizing when I touch.
What can I do? Is there any kind of fix for it?
It's really annoying (mainly while typing)...
Thank you for any help!

I guess its time for a replacement.

Made some research on other forums and found some people with the same problem, but on other devices...On Nexus 4 and Xioami (mostly)...They solved this by replacing the battery...I'll try to do that this week...
But any other tip about can help...

it might be a kernel issue
if u have jolla kernel try changing the kernel first

I have also the ghost touching on my E975.
Tried to do a scan with antivirus with no luck.
For instance it's hard to dial number, because there are ghost touches often.
It's like on tihs video, but I have touches even more often:
http://www.youtube.com/watch?v=EHFtafL-HKc
I'm on stock KitKat 4.4.2 ROM.
Any ideas about the issue?

It's relatively common issue, hope it will not appear again...

Sorry to resurrect this thread but I seem to have a problem with my screen, not with the ghostly touches but my screen has like one part of it not responsive to touches especially the keyboard. While typing in portrait mode I can't type in the letters x and d and the whole line of the screen above those letters can't respond to my touches. The others are OK though. Anyone else having the same problem or is it just me? Already flashed different ROMs but same problem

So...I didn't manage to get a new battery to perform a test yet...Maybe I'll do that until the end of this week, and post the results here...
About the kernel...Mine is "3.4.0 [email protected]" ...
Going to update to new Kevin's L ROM and see what will happen...Hope I can help u, guys...

I had the same problem as well, unfortunately my phone was just out of the warranty period so I couldn't get a repair or replacement. I tried everything to do with the software and firmware at first to see if that was the issue(no luck). I noticed when my phone was either hot from heavy usage or charging, it was at its worst..couldn't even put my lock pattern in without it spazzing out. After almost throwing my phone at a wall numerous times I decided to get a new digitizer (easily bought online at reasonable prices). Watched a tutorial on Youtube and replaced it successfully and haven't had a problem since.

So tried the touchscreen test and found out it was like a whole strip of screen that got affected. It was okay just a few days ago though,

Yeah no problem and thats unlucky. I've got the Korean variant and wasn't ready to wait weeks to get my new digitizer either from Asia. I managed to find a european version that arrived next day and included front housing aswell (although modifications were needed a bit for the internals to fit). Yeah the Moto G look great but it seems to be more of a downgrade from your current handset right?

I live in the UK I managed to find one here on ebay. I know you can get some from Italy , Spain and I'm positive there some in US aswell. Search "E975 housing or digitizer" depending on what your after. Do be careful as some replacements screens lack the LG logo or a bad quality. Im would give direct link but im not sure about the forum rules on that are. If your still unsure do PM me your country and I'll PM you back an appropriate link.
Hope I helped.

Bobbed into samsung store which has the Apple equivalent of the genius bar he said there is a update coming out Friday for unlocked devices which hopefully will sort the issue out and if it then continues then it may need a replacement but seen as so many of us are having the issue he thinks it's software related fingers crossed

It's a known issue, even some youtubers and reviewers addressed this. Apparently it can be fixed by turning off finger sensor gestures.
So obiously its a software issue, lets hope that Samsung will fix it asap

It happened to me 3 times now. Really annoying. Firest time I thought I didn't set my lock parameters correctly then the phone suggested a restart. After this, it happened again, and now, reading this I feel relieved.
Waiting for the update.
Regards!

you're not alone people!
same goes with russian unlocked S9+

I had this happen to me at least once a day.
Getting annoyed. Thinking of exchanging my set.

Popped in here just to check, as this keeps happening to me to. Hope the fix is out soon.
Had a similar issue on my Pixel 2 XL. Switched to the S9 only to find the same thing happening

I hope its a software issue.

I have the same issue and it's mostly when the battery drops below 20% approx.

had the same issue on my g9+ and my girlfriend has the same on her s9... also tried factory reset, but it didnt help.. :/ we sent s9 back to samsung.. so we are waiting to hear something from them..

Disabling swipe to open notifications via scanner works.
Update have just arrived. Installed- shall see soon whether it works or not

I've updated today to the latest version and it seems ok so far.

I have pre-ordered SGS9+ and FPS is faulty since day one. I have read Android forums and tried all solutions along with disabling gestures.
Sadly it still behaves like pice of sh!it.
Cheapest Xiaomi that lies on my shelf has blazing fast sensor that never failed. Samsung one rarely works, finger recognition is below any criticism.
And yesterday's update haven't fix anything related to sensor only the face and iris. Seriously I'm waiting one more week and I'm returning it.

My finger print doesn't unlock myphone when screen off. I have to use "intelligent scan" to unlock. So did you return your phone?

I am getting the same issue. Came from LG V20 where fingerprint was in the sweet spot. Never had an issue it instantly unlocks my phone. S9+ is driving me insane with the 2 step unlock.
