My newly purchased ZenWatch is set to have Always-On Screen but after 5 seconds it fades a little, then, shows the dimmed version for a second, then goes completely black so I can't see anything until I wake it again.
Wear version 5.0.1
Connecting to Android 4.4.4
This happens the same with any watch face I select: pre-installed or new custom ones. I have tried uninstalling Wear and ZenWatch Manager, resetting the watch and starting over again, same thing happens.
Could an app or watchface I have installed be interfering with the Always-On option somehow??
I don't know if this is related but I had to return my first watch as it didn't charge, so this is the second one connected to my phone (after 'forgetting' the first then pairing the new one).
When I click on the Always-On tick box on my phone, it immediately updates this option showing on the Watch so it's definitely sending the command to it. It shows as Always-On selected on the watch.
Has anyone else had this bug and know how to fix it? Thanks.
Is cinema mode on?

Thanks, no, cinema mode isn't on.
It's really curious, the screen fades slightly in brightness after five seconds, then goes to the dim version of the watch face, then goes completely black a second later. One tap brings it back so I'm it's like the regular off screen mode.

Hi,
I'm very curious to know if you have found a solution to this problem as my new ZenWatch is doing the exact same thing. Asus support has told me it's a firmware issue but that seem odd to me as the feature seems to work for others.

Oh thank you for telling me I'm not at least alone! No I haven't found a solution - I have reset the device, removed all the Wear apps one by one from the phone (in case a setting is interfering) and nothing makes it work as it should.
So... firmwear meaning the version of Wear that's installed on the watch? I was considering seeing what options are on the debug? menu but following online instructions I couldn't get this to work (you have to swipe from top left etc). I'm on 5.0.1 build LWX48S bought in the UK, how about you?
Have you had another watch that you replaced? I have and thought maybe settings got confused between watches. On my previous one, the always-on screen worked fine on it. When I booted it up for the first time, it did a software update. It however had a power problem (didn't charge after 2 days), so I replaced it.
The replacement didn't update when booted up, and doesn't update when I reset, so I assumed it shipped with newer firmwear - maybe the always-on problem is caused by this?
One weird problem with the replacement watch is that it notified me that it was almost out of power, despite having about 75% batter left, then it switched off and didn't turn on until charged over night. Only happened once.
I was planning on swapping it for another at the shop but someone else having the issue makes me think it's software. Might wait for an update, but if not solved long term then I'm not happy - I want it to look like a watch rather than a blank screen.

Just got my Zenwatch and I am having the same problem... Resetting the watch helped. But, I am still not getting the watch to vibrate on notifications. It vibrates when I set an alarm (on the watch) to it's not the vibrating device itself...

I have the same version of Wear with the same build number and I am also in the UK (which may be the common factor here as it is looking quite likely to be a manufacturing batch issue). When I first got the my watch from Heathrow terminal 2 it had an older version of Wear pre installed and the always on mode was not working then either. This would suggest the Wear version is not the issue here but the ASUS firmware which links Wear to the hardware is at fault.
I have also done the uninstall all apps from my Nexus 6 and factory reset the watch thing but ultimately it made no difference.
This the response I received from ASUS BTW,
Thank you for contacting ASUS. We are sorry to hear about this problem. I believe this is due to a firmware bug, it is not a setting that you can choose.
Please be advised that I will forward your feedback to our HQ development department to see if our engineers can resolve this problem in the next firmware update.
We are sorry for the inconvenience caused.
I also share your sentiment that a watch that doesn't tell the time is not much use to me so I will be rolling the dice and returning it for a replacement unit in the hope for a device that works as advertised.

Did you return it in the end?
After several frustrating emails with ASUS support in which they replied with general info on how the Always on-screen setting can be set, then asked me what build number I had even though I told them this in the first place, they concluded it must be a hardware problem.
"Taking in consideration that you have both the settings enabled on your watch as on your connected device and you are using the latest firmware, I also believe this is being cause by a hardware fault. Please return the ZenWatch back to your reseller."
So I took the plunge and exchanged it for the second time with suspicious staff at the shop (it was past their 21 day return policy cut-off, so I had to order another, then swap the new one for mine, on their system they refunded the new one). Hey presto, the new one works fine!
This one shipped with: 4.4w.2, KNX01W, updated to: 5.0.1, LWX48S.
So overall sounds like perhaps just a hardware issue. I know it's a new product but it's lucky I like the look of the watch so much that I'm tolerating quite a few teething problems. The one I have now has a very slight ridge on the right hand side of the screen where it meets the metal frame, which you can feel when swiping right. Hopefully I'm just being overly-fussy now and I won't notice after a while, but it's not as smooth as my previous two watches. On the left of the screen it's completely flush.

I went to take mine back last week only to be told by PC World that this product can only be bought on-line and I would have to buy another one and then return the first for a refund. Which is a bit of a scam to me as the replacement was at a higher price than the first one I bought from Heathrow Duty Free.
I am due to collect the replacement and have an argument about the price difference tomorrow so finger crossed I get a working one as well.

Ha, mine was from PC World too. I guess it's not their fault that your original one was bought duty free & therefore cheaper, but really if it's faulty they should treat it as such. They did offer me the option of booking it in as faulty, then it would have been sent off to ASUS and in all probability replaced with a new one anyways, but he didn't know how long this would take. So I just took the other option of buying another, having it delivered to the store the next day then swapping & refunding the latest transaction.

Well the good news is I now have the replacement watch and it works as advertised. I did have to complain a lot to get the difference in price resolved. I ended up complaining so much that the store manager gave me the money out of his own pocket just to get rid of me .
Note 4 wont turn on, "cannot boot normal" and "downlaoding target, dont turn off"
Its a Note 4 SM-N910F, Android 6.0.1, BB N910FXXU1DPE2, kernel 3.10.40-7733605 [email protected] #1
i feel I have tried everything... History:
Phone has been working fine for a year, upgraded to 6.0.1 no problems about 2 or 3 months ago. no new apps installed. Last week it started getting very laggy, keyboard strokes took for ever to register. I thought, ok, time to to a factory reset to blow out any old cobwebs. Did it via the menu. However the phone froze midway thought. I left it for an hour and then pulled out the battery. I popped it back in and it performed the reset without me having to press anything. Cool, thats good I thought.
Now I was going to change the battery, so I powered off as normal and put my other 2 week old original samsung battery in, and it would not power on. After a few reinsertions it powered back on. I though i have to do another reset. So I tried, and it would not reset. It just died. I cant restart the phone, it dies. If I shut it down normally. it wont turn on back on, I have to take out and reinsert the battery multiple times, holding down the powerbutton between to discharge. this can take up to 10 tries now. Sometimes it will go th the unable to bot in normal mode and "downloading , do not turn of target, but it will stay there for ever, more than an hour.
Every 15-20 tries it would turn on, let me get in via pin, only to start freezing up within a min, and then die again. Somewhere I read that a guy hada similar problem, and he used wakelock and that worked, on level 4. I managed to download that and used it, and hey presto, it works!
Now I had to power down the phone for a reason, and it took me about 30 min of battery and powerbuttonholding before it managed to boot up, and I was quick enough to start wakelock on level 4.
It wont boot in to safe mode, it wont boot in to recovery mode, it wont boot in to the factory reset mode. Its the same with either battery, and different cables.
Any ideas what i can do here, or what could be wrong? I havent gotten it wet or banged it.
I am having the same exact issue on a N910A. Phone was functioning correctly and in December it started getting really laggy. Performed various resets, purchased new battery. Still laggy. Up until two weeks ago the phone was slow but now it will not power on . The phone will not charge as well.
Mine did same, 6 months old, not rooted stock firmware. Locked up yesterday, couldn't do anything. Pulled battery and restarted. Samsung logo comes on screen goes black for android boot then it hangs with blue led flashing. Nothing I do gets it past that point. Tried safe boot but it doesn't fully launch with correct button combo and volume up. In the end I re-installed firmware using Keis. All went well, everything as per youtube tutorial. Except one thing, at end of download phone didn't re-start. Still can't get it to boot, any ideas?
Edit: Lock up didn't coincide with any new apps being loaded or updates of existing. Only change was a week ago which was an automatic update of the stock firmware (Lollipop)

are you still under warranty? i sent mine to a samsung center, the guy recognized the problem as the motherboard, said I wasnt the first. That was 3 weeks ago, they are STILL waiting for the parts. They say the Samsung factory are way behind with repair parts, etc etc. I am hoping it will go under warranty. Ill update when I know!
I've been having the same problem that started yesterday morning. I've tried a few different solutions but nothings worked, I get the feeling that my phone is dead and I'm not in warranty either. I'm going to approach Samsung but my guess is they will want more than the phone is worth to repair it. I've read about so many people having the same issues, its horrendous engineering on Samsungs part considering how much their phones cost to start with

Your guess is probably correct and I totally agree with you. I seriously think manufacturers do not want their devices to be problem free for more than two years. Probably why they have stopped making phones with batteries that simply pop out.

Definitely...surely it couldn't have been that hard to make a device with a battery that was still removable on the newer phones. It's frightening how many forum posts I've found with people having their phones just brick out of nowhere (and that's just the note 4). I've given up trying to fix mine, I've tried every method I could find and nothings worked. I can only assume that this problem is simply the motherboard of the phone not working anymore. I'm not even sure what phone to buy now but it certainly won't be a Samsung.

If you do not care about the camera thera are a lot of rather affordable options which can be tossed in the bin when they start malfunctioning and if their warranty has run out. If you care about the camera being as good as the Note 4's than the range of phones you can buy is quite limited.

If you are able to boot it into Download Mode then you should Download Stock Rom file for Galaxy Note 4 from Sammobile and Flash it through Odin..
Everything will be OK... ?

I think the camera on the note 4 is absolutley terrible. I might even go so far as to say the pictures are unusable. the applied noise reduction renders everything splotchy, colors are off and its not sharp at all. and Im not talking dark conditions here.
Anyway, my phone was repaired under warranty and is back to working as it should. It was indeed the motherboard, so if you have the same troubles I had, those are your best bets.
I don't think replacement via warranty will be available. I will attempt to power into download mode and verify if I can get it back up and running. If not, a good ole paperweight.

Sounds like the problems I have: with my first N910F: started with lagging apps / freezing, then random reboots now and then, eventually giving error messages when booting. Finally, now it will only start after the battery has been out for at least 30 minutes, but hangs on error message. When pulling battery out and putting back in it, wont give a single sign of life. Since I was just out of warranty it has been lying around, and I bought a second hand N910F for replacement, sadly its starting to give the same errors too and is just out of warranty too (its currently still working, but with freezes / reboots / and already a event with boot error).
I read It could be memory chips or some power chip on the motherboard, appears to be a common problem. So.... Last month I bought a new motherboard on ebay (chinese delivery, 80€). Received it last week and put it back in; phone is back to life. (putting it in is a very simple task, with iFixit teardown / guide)
Anyway, I love the Note 4 for performance / size / looks, and have been Samsung fan for a while, but this recent breakdowns and information that it is fairly common, has diminished being a fan fairly quickly and I guess the Note 4 will be the last Samsung device for a while after this new motherboard breaks down as well

My phone is also random Rebooting
It also shuts down at 25% of battery remaining, Have you also faced similar issue?
Download the app "Wake Lock" and run the Partial Wake Lock option. Apparently the updated software impacts the CPU. For the restarting issue, put it in the freezer for a couple minutes. You may have to take the battery out once, but it has worked for me every time.
This looks very much like the issue reported here:
https://forum.xda-developers.com/no...-error-fix-t3434335/post72944466#post72944466
There are temporary fixes (wakelock), but ultimately this is a harware issue, and the fix is a new motherboard.
I think that underlying it is a problem with heat affecting the eMMC chip or its connection to the motherboard.

Hey can u pls get me the stock firmware for n910gddu1dpb4
You might find this interesting. Since I couldn't get mine to power up at all, I called Samsung tech and they quoted me $75 to fix it and they would pay for shipping. I figured it was better then getting another phone off Swappa. 2-3 weeks later i get an email that they are repairing it under warranty at no cost to me. I got a refurbished phone since i know my IEMI number was different. they didn't explain why. Anyway, I got lucky i guess.
I've got a Samsung Galaxy S5 and I'm having this issue where several times a day the phone just shuts off. I'll go to pick it up and it's not on, and it won't turn on until I plug it in to power and wait for it to show the battery charge display.
I've taken the battery out and put it back in several times, and I followed some guide to clear the cache... EDIT 1: I have also done a factory reset as well.
If I remember correctly this issue only started after updating to 6.0.1 and didn't actually happen on 5.
My first thought is to try and roll back, however is there anything that I should try before this...?
Appreciate any input!
PS: Complete newb with Android.

I've never had this issue with my personal devices but, I had helped a few individuals with their devices spontaneously shutting off without warning.
I've found that 90% +/- of these problems ultimately stems from either one of the following.
1) The Power Button going bad by being worn out, loose or just plain sticking within itself or a worn bezel.
2) The battery beginning to go bad. The batteries going bad doesn't always reflect on the charge itself but, there's actually a small circuit board within them that talks to the device as well.
Out of the 2 above, I've run into more of the battery being the culprit than the power button.
I can't guarantee anything without physically looking at the device but, this is just my view as to my experiences.
Regarding this happening around the time you had updated your firmware, I believe that this is just pure coincidence. It's extremely rare for this to be tied to your Firmware without any firmware issues also being experienced.
I hope that this helps you out and I wish you the best of luck!

I DO NOT provide support via PM unless asked/requested by myself. PLEASE keep it in the threads where everyone can share.
Thanks a lot for your reply!
I'm no expert whatsoever but the power button seems OK from what I can see and feel. It presses in and makes a noticeable click and then pops back out.
I think the battery may be the culprit here. When it shuts down, I can't turn it back on -- removing and re-adding the battery doesn't help. Only connecting power helps.
I think I'll opt to purchase a replacement battery. I have no experience with this whatsoever -- what price should one expect to pay and do you recommend avoiding eBay? I don't want to buy a dodgy battery.

I have very good experience with this battery, I have three of them and they have a very good capacity:
https://www.amazon.de/GadFull-EB-BG...Batterie-Grün-Weiß/dp/B01B80ZWXU?ref=ast_p_ep
Thanks for your replies guys.
I finally got around to replacing the battery (spent $50 AU on it so not a cheapie)... however the issue still persists.
Any ideas what it could be? The issue still occurs even when safe mode is on.
I have rolled back to 5.0. Hopefully this will fix the issue. If not, I'm going to try to root it with a new version.
Any thoughts on what kind of diagnostics I could run to try and figure out the culprit?
(Assuming the issue will persist.)
Hello, in August 2017 I bought a cell phone LG G6. The cell phone works fine and in August 2018 I got an update for Android 8 (Urao). About a week ago, the fingerprint sensor stopped working. Every time I put my finger there is a message that you can not use the sensor and try to re-activate the cell phone. I tried to activate and after all this option to set the fingerprint does not appear in the settings of the device. I tried to turn on and off and did not help. I did a test by checking the hardware of the cell phone in the smart doctor and with the fingerprint sensor written "No response, contact the service center" . I tried to wipe cache and hardware reset and other reset. What can be done to fix this? Thanks in advance
I'm trying to figure out if it's related, but my LG G6 H872 (T-Mobile US) has been having the same issue. I'm on the latest build, software version 20d, security patch level August 2018. I'm fairly certain the problem wasn't present before I got the update, but if it was, it definitely got worse. Once in a while the fingerprint options will reappear in my Lock & Security > Biometrics settings, but when it's not working "Face Recofnition" is the only option listed. I'm supposed to have a second year of warranty coverage on hardware failures direct from LG so I'm thinking of filing a claim, but I wanted to sniff around first to see if this is an issue affecting others. I'd hate to get a refurbished replacement handset just to find out this is a software issue affecting everyone.
I got the 20e / October security patch update earlier this week and it didn't seem to fix the problem, however, I've found that powering off the phone for a minute may re-enable the fingerprint reader. I've tried the power-off & restart option multiple times and it doesn't work. At the moment mine is working, and it's been working for about eight hours straight. We'll see if it flakes out again.
Flaked out again, but eventually got it to come back on. Between leaving it off for a while and thoroughly cleaning the sensor something is making it come online again, if only temporarily. I have a theory that it's something about the heat of charging that's causing the issue. I only use the stock LG charger it came with as well as a generic unbranded fast wireless charger. I definitely remember the fingerprint reader error message beginning to appear a few times having just removed it from the wireless charger.
Just in case anyone at all is following this saga, I've decided to send my phone in for service under LG's second year promise warranty program. They asked me to try a factory reset and that didn't help. Then they asked me to send in photos of the front and back of my phone before approving my claim and providing a prepaid shipping label.
This what I did.
Hold the power button until it vibrates and let go.
Do it until the fingerprint error disappears.
Had the same problem, fingerprint worked sometimes, sometimes not.
Mostly it stopped working when it got warm.
After Factory Reset, the option was completely gone in the settings menu.
So I sent it in for repair, today I got it back and now it works again
They replaced the battery cover/back cover and did an software update.
Hi, I'm having the same problem with my LG G6 (H870, V30a-EUR-XX).
I tend to think its link to overheating as proposed by Technosquiq. Do you use a cover on your phone that could have induced a heat build-up?
I either get an bad detection (which can be solved by recording multiple fingerprints for the same finger) or I get two different errors (either "fingerprint not available" or "contact technical support", or something similar: my phone is in French).

I sold my G6 for a V30 few weeks ago, but when I did have fingerprint problems, it's VERY simple to do.
Ebay = brand new fingerprint button and cable..
Heat gun or hair drier etc
easy - and i am useless at ANYTHING ...but i did it nooo problem.

Hi, I have a LG K20 Plus. I currently can't turn the phone on, so I don't have much software information to give you. The phone was bought at T-Mobile (Metro by T-Mobile) and I had a SafeLink sim card and a 16 gb micro sd card inserted when the issue started. I have since removed both. It says Qualcomm snapdragon on the screen when it starts. It was also rooted and the bootloader is unlocked.
I broke the screen on my phone and I decided to do the repair myself. I have done about 7 or 8 screen replacements and I actually did this phone a year ago with no issues, so I felt I could manage this one as well. I bought an entire display (from ebay) and switched it out with no problems. Initially it worked great! I used it for a few days before realizing that I had no sound. I opened it back up and noticed the loud speaker had fallen out. I found it, put it back in, reassembled it as I normally do and turned it on.
NOTE: when I was reassembling it the second time, I actually tried to put a screw in a hole that wasn't a screw hole. I used a light to normal amount of pressure but I didn't force it. I think it's the hole where the moisture detector is. Picture #1
I turned it on and right after the logo screen I got a message that said "High temperature detected Powering off for your safety" and it immediately shut off. The phone does appear to charge normally but it won't stay on. I did a factory reset (I'm not sure if it's still rooted but the bootloader is still unlocked). I also switched back to the old (broken) display just to check if that would work. I couldn't see any difference in the shielding but I switched them just to be sure. I bought a new battery and installed it. I took a q-tip and 95% Isopropyl Alcohol and cleaned pretty much the entire motherboard, paying special attention to the battery connections. After each one of these things, I tried to start it with the same error message immediately upon start up.
NOTE: At no point has the phone every physically felt hot or even warm. I don't think it's on long enough for it to get hot. But something is wrong and I have no idea what it is. I, literally, took the phone apart, put in the speaker and put it back together in less than 5 minutes. Could it be I just bumped something and knocked it loose?
I searched for any information I could find both here and with google but there is next to no information on the LG K20 Plus. I did find some information on the LG V20 that had overheating issues, and that has been all the luck I've had. I watched several videos and it seems the solution is to apply thermal paste. But my phone doesn't have any evidence that thermal paste was ever on it. I went and bought some but I have no idea where exactly to put it or even if it's needed. Most videos showed people using some kind of aluminum foil but I'm not sure if that is safe. I have several old phone laying around and I managed to get some of the silver tape and a copper square thing but, again, my phone did not have these things to begin with. I don't want to start adding things only to make it worse.
There is a slight difference of the tape that is on my phone now (the display I just bought) as compared to the old one (broken display). Picture #2 Again, I have no idea if that means anything but I thought it worth mentioning. Picture #3 is how it looks now as if I were going to put it back together. Picture #4 is the part (don't know name) where the videos show to apply the thermal paste and the shielding.
I'm really at a loss as to what to do next and I can't really afford to take it in to have it repaired before next month. If anybody has any insight or answers as to what happened, I'd be very grateful for your help. I'm sorry for the long post. I just wanted to tell you everything I have done in detail. Thank you
If you're using Kernel Auditor or any other kernel adjustment simply reset to default and use only ondemand or interactive. There's also options for the thermal portion of the kernel, don't mess with those. If VCC or another thermal option was checked off turn it back on. Putting the GPS to the moderate setting (the one below high accuracy) will keep the temps down as well. Are you using a custom ROM? If you're on Discord you can feel free to message me SCOPE★ BRΞΛD #8460 . I am only offering that so we can get this resolved quickly for you, just copy and paste since I use special characters.
Omgosh, thank you so much for taking the time to respond! Although I'm sure everything you are saying is very smart, I have absolutely no idea what you're saying. I'll do my best to try and answer you. I don't know what SCOPE is or how to send a message there. I don't think I'm using any thing for the "kernal". Also, I don't know what VCC or Discord is. As far as turning off setting for GPS or any other app, the phone will not stay on. I get about 1 sec after the logo when it boots up, then the error message about overheating and it immediately shuts off. I did a factory reset so everything should be good to go as far as apps. I don't think I'm using a custom ROM. The only thing I did was install TWRP, unlocked the bootloader and rooted the phone a year ago but nothing since then. As I stated earlier, this happened right after I did a display repair. Is there something on the MOBO that can get bumped that will make your phone get hot or send a overheating error. My phone doesn't show any sign that there was ever thermal paste on it prior but should I add some now. Will that help?
Update... Now the phone does not power on at all. When I plug it in to charge it I get an error that says "Device temperature is too high or low. Please move to another place to charge. I wonder where you went. I googled SCOPE so I could sign up to message you like you asked me to but nothing but definitions came up. I know I'm out of my league here. You guys all talk so technical. I didn't understand one thing the person asked me for. I know it's rare to get a response as quickly as I did and I was so happy to see someone had responded. Now, I just feel stupid and defeated. I thought this site was inexperienced with cell phones friendly. I'm just trying to get help so I don't have to go out and buy another phone again. Can someone refer me to a site that is more directed toward people who don't know much about the technical side of cell phones... please! Again, thank you for your time.

Hey, I just wanted to say sorry this happened to you. The same thing happened to me. My LG K20 Plus, no matter what button combinations I push and for how long I hold them, will not turn on or go into download mode. Plugging it in to a charger or PC does nothing either. Before it got to this state, I got the infamous green screen of death/Demigod crash handler (google this--it's a known issue with some models of LG phones and it happens when they overheat). It's definitely a hardware/build issue, and especially since this issue keeps the phone from turning on or connecting to a computer, I don't see a workable fix short of buying a new phone, unfortunately. Again, I'm in the same boat so I'm not happy about it either. I would say XDA is by far the best site to find a fix to this sort of problem, so if no one here has any suggestions on how to fix it, I think you (we) may be out of luck.
Thank you for letting me know. I'm not sure of some of what you said but I did catch the bottom line. Basically, just hold onto the phone until someone here comes up with a fix or workaround? I have a question for you. Did your problem start after you did some kind of repair? I'm wondering if I bumped something on the mobo to make it give a false overheating error. Do you happen to know where that sensor might be located? Sorry you are having problems to. It really stinks when your phone breaks and no matter how much time and energy you put it to figuring out the problem to fix it, there just isn't any good answers out there. I wish you lots of luck and if you figure anything out, please update here so I can try it too.
You need a whole new phone.
That or you're gonna have to replace the hardware
