[Nexus 9 Q&A, Help & Troubleshooting] juandiegofx:
Something similar happened to me with the tablet, in my case it is a 16GB WiFi HTC Nexus September and since I have tried two one based on AOSP 5.0.2 (Simple ROM) with KernelMOD ElementalX and the other based on 5.1 (Lollipopalooza) with Kernel Stock and both happened to me that problem, and I know that

1) It is not by temperature as it passes this on a NORMAL temperature range around 58 degrees Celsius in the CPU ..

2) Not the Kernel as such these two compilations or any modification to why I tried that detail.

Now this in my Tablet has a competition and it happens when in a level of less than 50% charged battery, and always happens when the game is, digase Asphalt 8 Airborne or Clash of Clans, is played if more above that level HAPPENS no charge, sometimes at 20% load vecez other 40% is in order, so I think to do is try a CustomROM CM12 is based on the AICP and look as if no re comportao the stock of Google and look if it happens, if it happens again I hope the 5.1 official Google thing that I think is a hardware problem promptly which can only guarantee remeasure, so will give you time to Google it pleases removing the Firmware 5.1 and the amount and if you stop not happen then, because I feel TERRIBLE guarantee that HTC and Google, as costs provide a team with such problems, and it should be emphasized that BEFORE not happened to me, it came to pass after almost 7 MONTHS ..

PD: That sorry for my English but not my original language, use Google translator.

Those are exactly the circumstances in which my tablet flickers !!!!

Anyways,...everybody just listen and hope this solves your problems too !

The main story :

I installer cm12...and it still flickered....so as a final resolution, I took off the back-cover.

During the removal, I made sure that the camera won't go off, BUT the important thing is that I accidentally unplugged a little-little cable found on the right upside of the tablet (when facing screen down = in the other corner from where the camera is found AND the tablet was held in portrait)

So...after re-plugging that tiny cable back on its port (I think that's what that little whole was named) and playing a little bit with the copper thingy..... I turned on the tablet (without the cover being attached) and it lit up with no problems or whatsoever. After that, I power it off (just to avoid any sort of short-circuit damages ) and put the back-cover.

I have to mention that I heard some sort of click in the up-center of the tablet while I was pressing it to make sure everything was reattached as initially (I think that maybe was the NFC antenna)

Finally, I powered the tablet on....and after charging it to 100% and installing all my apps, I ran Antutu benchmark just to make sure everything was ok. Surprisingly, it passed on without even the slightest sign of flickering.

To sum up : I think the problem was the NFC antenna, somehow interfering with the tablet OR it was that little cable I disconnected, but then reconnected back on.

Now, it's been 7-9 hours and no sign of flickering yet. I really hope this solved my problems as well as yours too.

I'll get back with the results of this "fix" after 24-48h, just to confirm that everything is Ok !

Sorry, I accidentally double posted .
[Nexus 9 Q&A, Help & Troubleshooting] juandiegofx:
I understand, the thing is that did not happen before and now if, which I think is HORRIBLE from HTC and Google to do that, I'll try the Stock and AICP be like going because I go back and repeat, I happen to be bloquela picture completely, is color WHITE or BLUE entire screen and then a super annoying SOUND, which only the button OFF let it down for 6 seconds passed, and then it goes but the crowd as he said it while riding levels low battery at 60% levels up does not, and at first either wrong, and ever since I've been dropped or the like.

So I'll be testing with a logcat to watch that event happens when the system be FROZEN, although I think it's hardware because it is illogical that in no battery HIGH levels and LOW pass if ..
[Nexus 9 Q&A, Help & Troubleshooting] mihaicristian:
Please do so ! And for the record, my N9 had the same symptoms !
[Nexus 9 Q&A, Help & Troubleshooting] techiedj:
Well I've been back on stock for a week and all was going well, but I came home today to the boot lock screen. It had froze and rebooted at some point all on its own. It also had a lot of trouble booting back up. Slow, laggy, and proceeded to reboot 3-5 more times before ever getting back in to the home screen past the initial boot lock screen. At this point I have no idea what the problem could be (bad storage?) but its definitely a hardware issue and I will be talking to HTC about replacement soon.
[Nexus 9 Q&A, Help & Troubleshooting] mihaicristian:
So..., the issue still persists, ALTHOUGH it is much more manageable on CM than on stock ROM. I think I'll wipe the device and try again with the back-cover, since that sort of settled things down a little.
[Nexus 9 Q&A, Help & Troubleshooting] anx.go:
I am on stock ROM and I have the same issues! Did you find a way to fix it?
[Nexus 9 Q&A, Help & Troubleshooting] mihaicristian:
Unfortunately not. I'm waiting for [MENTION=5445589]juandiegofx[/MENTION] to reply back to this thread and tell us if he could find something with logcat. I'll try logcat too during this weekend. Maybe I'll find something. I really hope it's not a big hardware issue (apparently, all the tracks lead to some sort of hardware problems).
[Nexus 9 Q&A, Help & Troubleshooting] juandiegofx:
Mate, I have not flashing to the original firmware Nexus 9 or any CM12, because I been trying to SimpleAOSP yet, have you conrruencias see and then as now not returned happen to me, I have not seen reason but as I said always happens when I have less than 50% of battery and has started some relatively heavy title, I put my son play and as active logcat to identify hardware ... but everything points, discupa not report me before.
[Nexus 9 Q&A, Help & Troubleshooting] mihaicristian:
>3 days without flickering !!!

I took off the backcover again...played a litiile with thr battery cable this time.....and that's really all i did. Also I stayed on CyanogenMod and dirty flashed almost every nightly.

To sum up, my issue seems resolved. I'll get back here if something goes wrong
[Nexus 9 Q&A, Help & Troubleshooting] ayoraider07:
I am also experiencing the frozen/flicker screen problem. It has happened on fully stock system, and on custom kernel/rom as well. Strangely, never happened in the 1st 6 months of owning the N9... I'm trying to get it returned/RMA'd to HTC, but first I was told to boot into safe mode(press power to turn on tablet, let go of power when google logo pops up, press and hold volume down until the OS boots up completely), and see if the problem still happens....

I believe the recipe to recreate the issue will be <50% battery, freeze/flicker usually happens to me while browsing the web, and I think while the tablet is charging as well... So far the N9 hasn't froze (battery draining from 100%, at 60% now) .. I will provide update tonight
[Nexus 9 Q&A, Help & Troubleshooting] mihaicristian:
Thank you ! Yes, apparently your recipe is correct :)). As far as I know, the N9 is fine if it's plugged in to charge. I haven't experienced the flickering for quite a while now, but I'm really concerned that my "N9 is fine" period will soon get to an end. :((
[Nexus 9 Q&A, Help & Troubleshooting] ayoraider07:
So even in Safe Mode, the N9 experienced the screen freeze/crash. I waited until battery was ~20-30%(device was running pretty hot for a while; I was running music, maps, and youtube for 3 hours straight), [I don't remember if I plugged it in first...]but I opened up chrome(5-10 tabs) and voila! White pixelated screen and high pitch noise from speakers. HTC is allowing me to send in the tablet now for RMA repairs.. I doubt HTC will tell me what their repair/service department finds defective with the device, but if I find out, I will update this thread.
[Nexus 9 Q&A, Help & Troubleshooting] ayoraider07:
Got my tablet back from HTC repair, customer support said they swapped the mainboard. So far, it is working fine.
[Nexus 9 Q&A, Help & Troubleshooting] mihaicristian:
I tried to remove the hardware buttons so i can make them more clickable, but in the end i just put them back. I've been on CM for a while now, doing dirty-flashes all day long and luckily, I haven't experienced the issue anymore.
[Nexus 9 Q&A, Help & Troubleshooting] juandiegofx:
BAD

Good companions nights, I apologize for the delay in reporting my problem but things work and family, had been unable but the reality is that I realized that the problem has NOTHING to do with the SOFTWARE, if not with the HARDWARE as probe by installing almost all CustomROM based on AOSP, CM12 and CM12.1 and nothing ever when riding ranges of 60 to 40% of physical battery charge when playing a game of pretending to be plaintiff GooglePlay level 3D arises the problem of the screen, a HORRIBLE sound of the speakers that leaves one stays DEAF be colorful FROZEN WHITE or GREEN or BLUE and, and as this is TERRIBLE by HTC and GOOGLE they join a team that has these problems, and as I read in the history of the other partner may be something related to the PCB or BATTERY MOTHERBOARD as such because when riding ranges that problem happens.

For my part as I said, try different CustomROM and Firmware, different CustomKERNEL and nothing, everything is the same thing sometimes happens sometimes not and is SUPER tedious, and not even because I could conclude also as they try to record the problem through logcat but still will not let me record the total LOCK report because the tablet arises and no time record LOG hence is HARDWARE, so as soon as you can gestionare the WARRANTY, since I live in Colombia and shop at BESTBUY of USA, so I'll have to manage a FAMILY, however thank you very much for reading the POST and BAD for HTC GOOGLE and shows a device so I have very annoying that.

PD: Sorry for my English but use translator for since my original language is SPANISH.
[Nexus 9 Q&A, Help & Troubleshooting] GibsonSGJ:
My White 32gb Nexus 9, which has been performing very well since I got it at Best Buy in January, suddenly froze with the scrambled screen while browsing with Chrome yesterday. It was completely stock, locked and running 5.1.1. Had to power down by holding the power button, and upon reboot it would immediately go to a frozen scrambled screen after the spinning dots and android logo appeared so I couldn't even get into the OS. Clearing the cache partition made no difference so after multiple attempts I did a factory reset from recovery. After doing this it started freezing while the dots where spinning during start up... every time. I called HTC and they bypassed the trouble shooting as I could only get into the bootloader, but now I have wait 7-10 days for a tech person to call me about this thing before I can send it to them under warranty. For the hell of it, I plugged it in and tried starting it up and amazingly it booted right up so I decided to check "enable OEM unlock"and go for flashing the factory image to see if it resolved the issue. I was able to unlock my N9 and flash factory 5.1.1 with no issues at all. The whole process went flawlessly. Unfortunately it made absolutely no difference to the issue. It would still only boot while plugged in and charging. If it was off the charger it freezes during starting up on the spinning dots. I guess I'm at the mercy of HTC and their 7-10 day phone call at this point. Did anyone who sent theirs in for repair have any issues since getting it back? What did they repair or was the unit replaced entirely?

So disappointed right now. My N9 replaced my old N7 2012 and I use it daily.
[Nexus 9 Q&A, Help & Troubleshooting] GibsonSGJ:
Did you ever get this issue fixed or did you have to return your N9 for repair? I'm having this same issue now after a near flawless N9 experience since I picked it up from best by 4 months ago. I was completely stock. I've since unlocked and flashed the factory image for 5.1.1 and it makes no difference. HTC warranty is have some tech person call me in 7-10 days to suggest I retry everything I've tried myself already, and I'm sure then I will have to return it for repair or replacement. Grr
[Nexus 9 Q&A, Help & Troubleshooting] mihaicristian:
I will try to send back the tablet this Monday. This tables is basically useless with these issues !
[Nexus 9 Q&A, Help & Troubleshooting] funkybrunk:
So, I never had this issue with my N9 until I installed 6.0. It happens all the time now. I flashed back to stock 5.1.1 over the weekend, and the problem disappeared. I updated to 6.0 again, and got the issue again shortly after reboot. Not happy.

Nexus 9 - final conclusions

Sorry for the huge delay between posts.

Nearly 6 months ago, after arguing with amazon, I returned the Nexus 9 and received my refund. It came as a surprise to me that when I tried to buy the tablet again, but Amazon listed it as unavailable due to many user's complaints, so I just kept my money.

Now, that I own an S6, I must say that the Nexus 9 is not worth it ! Its price vs build quality is outrageous, performance is dissatisfying and battery life is terrible. Not to mention our little issue here at xda with the screen flicker.

To all of you reading this post,in my opinion, I would strongly recommend you to try to get a refund for your tablet or sell it, if you have had a bad experience with this tablet.

Have a good day !
[Nexus 9 Q&A, Help & Troubleshooting] gianmarcorev:
If someone is still interested in this, I had a similar problem. My Nexus 9 suddenly started to freeze and shutdown by itself, and most of the times after that I could not even power it on. Since I have no more warranty, I opened the back lid and I found out that the cause of the problem was the battery connector (a white connector above the battery, on the left) making a bad contact. I just pushed it down to restore the correct electric contact and now the tablet works like a charm. If the problem comes back you can fasten the connection permanently with a bit of glue. Hope this can help you!
[Nexus 9 Q&A, Help & Troubleshooting] vladdracul1431:
This is essentially a very common issue with the Nexus 9. IF you bought through Google directly, you're more than covered as I heard they extended the warranty to two years. If not, you're pretty much screwed. Reports on other forums show this to be a mobo problem and HTC will not cover it if it's more than a year after the purchase date. Additionally, it's been reported that the repair runs around $240 not including shipping. I'm curious, though, if any of you XDA types have been able to identify root cause. It gets progressively worse and worse to the point that i'm now crashing at between 60 and 70% battery even with it plugged in. I'm furious at the unwillingness of HTC to admit this is more than just a few tablets. I've decided that, since the cost is so high to repair, I'm just moving on to the Pixel C.
[Nexus 9 Q&A, Help & Troubleshooting] Suici Doga:
This is known problem with some Nexus 9 motherboards. My Nexus 9 has no problems and sometimes gets as hot as 80C while the battery is 43C.

Try to revert everything to stock and see if it happens.

I do not play 3d intensive games on my Nexus 9 and only 2d ones
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] IWellHeThanks:
I've been using my S5 for a couple weeks, rooted on 4.4.4 NI2. Mostly I'm using the Samsung keyboard since I actually like the layout. Autocorrect has increasingly developed very strange tics which are extremely frustrating, especially since it doesn't let you backspace and correct the word (if you try that it'it'll just "correct" it over and over again, the only solution being to type another word after and then insert a space between them). For instance, one "word" which has spontaneously appeared in my predictive text is it'll'll. It seems to have particular trouble with words using an apostrophe.

Is there any way to root out this obnoxious behavior? When I refurbished my S3 and wound up on 4.4.2 I ended up disabling autocorrect because of similar issues.
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] Tulsadiver:
You could try going to settings, application, Samsung keyboard and clearing data (maybe cache too if that doesn't work). I also saw where some people said they went to language and input, Samsung keyboard settings, unselected predictive text. Turned off their phone. Then went back and reselected it and it worked better. I like the google keyboard so I don't have these problems.
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] IWellHeThanks:
Well I tried the second option and we'll see how it goes. If that doesn't work I'll try the first option. I'm worried it'll unlearn some of the words I taught it, like "them", "form", and "easy". I heard it had a problem with 4 letter words but I didn't expect those to be among them!
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] IWellHeThanks:
Samsung Keyboard is unusable!

I tried clearing the data, the cache, resetting the predictive text. . . none of it worked. Samsung keyboard seems to have a tic when I use the apostrophe which causes it to insert text that repeats what I just typed. This is coupled with an insistence on "learning" every misspelling I make as the correct way to spell a word and then refusing to change it.

I deleted some stuff when I rooted my S5, more than was recommended in the thread. Maybe that's the problem? Because there's no way Samsung Keyboard could have a big this bad.

Maybe it's time to upgrade from the stock ROM to Eclipse, though I suppose it might not be any better because it's a keyboard problem. Trying different keyboards now.

Hey guys

After a long delivery time I've finally received my original Xiaomi 16000 mah powerbank.

I've seen many reviews with showing a charging speed for phones up to 2,1 A. I unfortunately get just 900 mah max. out of the powerbank with my Nexus 5. I use the original Xiaomi cable and I'm sure that it is 100% an original powerbank.

Did our phone get so old that it is not possible to get charged by a powerbank above 1000mah? :(

BTW' my gf's xperia z3 was getting charged with roughly 1500mah..

Thanks for any advice and or tips!
[Nexus 5 Accessories] shellsuper:
The same here

I could not get more than 950mah
[Nexus 5 Accessories] miskokupuje:
Noooooo!! Just bought the Powerbank because I thought that I will get the high speed charging up to 1,5A..

Does any of the Nexus 5 pro's have an idea of how to get the maximum speeding charge out of the Xiaomi powerbank?

I would be so thankful!!!:)
[Nexus 5 Accessories] nexus5x:
It gives me around 1.2A~1.3A using anker's 1ft cable

and it drops to ~1A when it reaches 70% or 80%

the maximum value i ever got on my nexus 5 is 1.7A using anker's car charger and 1ft cable
[Nexus 5 Accessories] miskokupuje:
Thanks for the experience. Did you use the Xiaomi powerbank and got up to 1,3 A while using the anker cable not the original Xiaomi cable?
[Nexus 5 Accessories] shellsuper:
I have the same cable and no more than 960mah whatsoever .

what kernel do you use ?

**EDIT: OH YES !! on kernel code blue i get 1.2~1.3A like you said . Using the anker & the xiaomi cable .
[Nexus 5 Accessories] nexus5x:
Yes , i did use xiaomi powerbank with anker cable and got 1.3A.

By the way, i'm using franco kernel .
[Nexus 5 Accessories] miskokupuje:
Does that mean that I can't get the 1.3A out of the powerbank without rooting my nexus 5 or getting a new kernel? :(
[Nexus 5 Accessories] cptscruffy:
I have the 10 000 mah 2.1 amp mi power bank.

Hm I have been on elementalx for the longest time.

Most cables give out 900 for me too.

Although, I do have one cable purchased in hk that helps my phone draw 1.2-1.5 amps from the mi power bank.

That same cable gives me 1.5 to maybe 1.7 draw from 2 amp asus t100 tablet charger.

I think the max draw the nexus 5 is made to achieve is. 1.5amp. If the draw goes higher, i think it is hardware regulated back to 1.5 amp.

This all being said and done, the mi power bank shows as AC charging to my phone.
[Nexus 5 Accessories] lesp4ul:
The included charger has 1.2A max output, 900-950 is normal for safety purposes.
[Nexus 5 Accessories] Axel85:
At least 1750 with oneplus one charger+cable...it s tested by me .For great current draw you need:

a good quality and short cable (80cm or less)

a good chargher with real specs ( I have an acer 1a that gives only 0.3a and it s s*** even if it s branded)

and maybe a kernel???? I use code blue in cm12 official nightly

If you re interested in charging tests read my thread here : http://xdaforums.com/google-nexus-5/accessories/micro-usb-cable-improving-charging-time-t3068562
[Nexus 5 Accessories] cptscruffy:
To confirm to my previous post; according to http://www.anandtech.com/show/7517/google-nexus-5-review/3 the nexus 5 is indeed hardware limited to a 1.5amp draw.
[Nexus 5 Accessories] vn00914361:
I don't know why y'all choose this one. I've been using EC Technology 22400 mAh Power Bank (model B30224) for months without any complaints. Constantly receive 1.9A input when I charge my Nexus 5 alone using 3ft Anker cable, and fully charged within 30 minutes no used

I wasn't sure if this belonged in Q &A, since its not really "phone related", but its fine to move it if it should be there..

I know some of you have done this before, so I wanted to ask what is the best way..

Went to look at the S6 edge yesterday, and I really liked it.. Unfortunately, I have no jumps left until august, but my wife and son do. After talking to my wife, it looks like she will take my note 4, and I can use her jump to get an s6 edge, but not sure what's the best way to do it.

Should we just "pretend" like she is jumping to the S6 from her Lg G3, and after she has it for a day, call Tmobile, and tell them she hates it, and wants to switch phones with me, and take my note 4, and ask them to switch the phone numbers on their end? At that point, I will just wipe my note 4, which is rooted, and put what ever she wants on it for her, and also do a factory reset on her S6 edge, and set it up as my phone.

The note 4 and the S6 Edge have 2 different kinds of sim cards, so I can't just put my sim into her phone and use it that way, so the "switch" has to be done at the T Mobile end..

Is that the best way to do it? Will T Mobile refuse to switch numbers for us? Is there a better way?

Thanks for your suggestions!

I did this twice already and they are cool about it. Just go into the store with her phone and JUMP to the new one, then swap SIMs. Being the S6 and Note 4 have different SIM sizes you will need swap that as well.

The JUMP is charged on the line but on it is actually tied to the Payment Plan/Device.
