Develop Bugs

CAUTION

I request users to please check the screens closely of their Xperia ZL. Disable the "auto-brightness", keep the brightness to maximum and set the screen time out a little higher say 5 minutes. My Software version is 4.2.2. The screen FLICKERS. I had my previous Xperia ZL exchanged because of this problem and the "new" phone has the same issue. I am currently having a miserable experience with Sony and their service centers here in India. My previous ZL had a motherboard problem and I am not totally sure if the "new" one is really new or the old wine in a new bottle. If things persist like this I'll probably head to the consumer court.
Any inputs will be greatly appreciated.

Then surely it's a case of me being conned.

No problem on mine either. Please do note that there have been some reports from Z/ZL users having screen flickering experience after upgrading to 4.2.2.

Hmmm the problem seems to come and go. But my previous ZL had a motherboard issue as confirmed by SONY. As I'm typing this message, there's no flickering at all. I am confused. I want to get things right within the warranty period.

Yes, it is very frustrating. Some just restart their phone and the problem is just gone. Some experience the problem again after a few days. And not many people have this problem. So, we can't tell right now if the problem comes from the new firmware or from the hardware itself.

When I keep brightness full n that brightness slider is on screen it flickers once while rotating the screen.. When I remove that brightness slider n go to main settings menu no flickering occurs also when auto rotate off no flicker...i thing but I never use full brightness n moreover it flickers just once before rotating so I guess nothing much to worry.

Hmm btw another question, the replacement unit I got comes loaded with those wallpapers one usually sees in demo units. Here, the ones in the last few rows. Please check this link :
http://forum.xda-developers.com/showthread.php?t=2152482
And is it true that it's not possible to get a SIM running in demo units? I am able to make and receive calls but, for some reason I'm getting a feeling that the replacement I got is a demo unit. The IMEI number on the box and that of the phone are the same but the box does not contain the charger, earphones and the USB cable.

BTW, what I mean by flickering is CONTINUOUS faint flickering of the screen. On the entire screen. The screen shivers!

Yes only the phone was replaced by them. But, the flickering comes and goes. I am having a horrible time here. Is there any chance of a refund? Worst case, I will ask them to give me an XZ as I have lost all faith in ZL anymore.

I have done all possible things from my end. My first ZL had a motherboard problem and after much argument, I got the replacement which isn't any better. They initially wanted to replace the motherboard only but I rejected it. I had asked for a completely new phone.
I usually keep the display at "auto". But now, I have kept it at "max" to check if the flickering occurs. It comes and goes. I last saw the flickering today morning. I will ask for a refund since I cannot keep a faulty product. And, I agree with you about ZL>Z in many aspects. This phone fits my requirements perfectly but what I have been going through over the past few days...a real nightmare.

i understand your problem like you i am too a little touchy about my devices faults..then its better you directly demand talking to one of the executive manager. bt sad to say ,i dont think they will refund.and this time if they exchange ask a sealed box.

It's 100% related to the 4.2.2 update, so be comforted it's not in anyway hardware related. This was one of the primary reasons I downgraded back to 4.1.2.

The problem is temporarily solved with a fresh install of the 4.2.2 update and then randomly comes again. I do not know what to do. I am forced to run to the service centers time and again. Is there any way to downgrade to 4.1.2 without losing the warranty?

Yes, you can downgrade back to stock 4.1.2 firmware, many of us have done it (flickering was one of biggest reasons). It will keep your warranty 100% intact since the bootloader isn't touched. Remember, only unlocking your bootloader voids your warranty, and you're not doing that here. You're simply using a 3rd party tool (Flashtool) in place of Sony's PCC/SUS tool to flash a 100% stock Sony ROM.
Just follow these instructions I posted last week: http://forum.xda-developers.com/showthread.php?t=2342680

Please help!!! My G4 H815 hard bricked without any custom software or rooting

The decive is only recognized as qhsusb_bulk. And I never messed around with any custom roms or rooting. The power went off suddenly and couldn't turn it back on. Please help!!!!

If you were not doing any sort of modification, it sounds like a hardware failure. Get a warranty replacement if you can.

Nope the battery didn't run out. It was about 80% left. And above of all, I was in the meeting at that morning and i put down the phone in silent. After that, i couldn't be able to double tap anymore then I tried power button at the back. I even try plugging the charger in and pressed the power button. Tried to factory reset it. And tried using different adapter and cable. The led light didn't even turn on. But when i plugged in to my laptop, i hear the noti sound and it shows qshusb_bulk in the device manager. I think it's on qualcomm mode. I saw some posts about unbricking g3 which is on qualcomm mode but no luck for G4.

It must be hardware failure but I don't have warranty. See the thing is I'm in Myanmar. The authorized distributor only sells dual sims model. But i never planned to use dual sims ones. So i tried to get the single sim version from singapore and the warranty from that country doesn't really seem to be able help.

That error means the bootloader is corrupted. No way to fix it currently without the right software and LG proprietary firmware. Not available anywhere I looked for the G4 (for the lay person at least). Since you weren't tinkering with it, could also mean the memory is bad.

Call LG.

Ask on lgviet.com there are guys that can repair a dead boot. One even wrote here I dunno if it was Manhit or else. They are in Vietnam, not too distant for you maybe
Edit it's @vn_mobile

I had one do the same thing. Warrantied it.

Contact the seller and ask if they can help. it would mean you send it to them, they sent it over to the service center and when its fixed return it back to you. you will be spending for postage. there is a warranty but its in singapore.

Agree, quite rare, but it does happen. On my original Galaxy Nexus, the CPU just crapped out and died one day. That was the repair facility's assessment.
Flash memory specifically, not so much.

G4 bootloop: LG officially admits hardware fault, will repair affected devices

Hello, good news!
LG finally admits the problem. Then it will be easier for us to have our devices repaired/replaced! :highfive:
Some of you already shared links on several topics related to bootloop, I think it's better to create a new topic about it, as I wrote an article too for french customers
English: http://www.androidauthority.com/lg-admits-g4-bootloop-problem-hardware-fault-669603/ (official statement)
French: http://www.gamergen.com/actualites/...engage-remplacer-unites-defectueuses-269974-1
For european customers/people who bough it from UE reseller, no worries:
bel57 said:
P.S. furthermore, European Union stipulate under directive 1999/44/CE that it allows users to modify the software, root included. This modification *DOES NOT* void minimum warranty of 2 years on hardware supported by the manufacturer.
Voided warranty by "illegal" software modification has been classed as an unfair term and it's fought by U.E.

EDIT2: Ok guys, I *finally* got my G4 back.
LG PROJECT P1 (H815 - LG G4)
IMEI changed
S/N 505x => 602x
Repair: SWAP motherboard, software update (20D)

But would we all be subjected to the warranty? Otherwise it's not different from before.
At this point it seems like they just realized what the problem is after wrongly sending back a few units as 'repaired' even though it's still having issues.

"Customers who purchased their G4 devices from non-carrier retailers should contact an LG Service Center with the understanding that warranty conditions will differ. "
If you purchased your G4 from a third party website/eBay, it's more difficult to get your warranty recognized.. best is buying it via carrier, LG official store and recognized sellers.

Are they also going to apply the fix during the production of newer LG G4s? because if not, it sounds like all lg g4 will experience the bootloop sooner or later and will only repair it after it has happened

Yes, no detailed information about it, but it seems that they already changed the production process weeks ago and they're just late to communicate on the identification of this breakdown.

"For in warranty repair service, you must include a copy of the proof of purchase inside the product packaging returned to the LG Product Repair Center."

Well, I can't see any problem here. You need the original invoice, that's uuuh.. normal?

I just bought the g4 and sadly discovered that my S/N started with 505. Thanks god i did not unlock the bootloader. But I really want to unlock it to install custom rom. I'm thinking of sending my device to LG even if i didn't have the bootloop yet so i'll be sure not to get it after unlocking the bootloader and then having LG not repairing my phone. What do you think ?

Just use it and stop worrying, your device may not be broken as ours.. and no, you can't leave it to repair if it doesn't have the bootloop thing.

So where are all those people now who always wanted to prove not many people are being affected or it's a common thing to have problems when they first come in the market???? I wanna see their faces... I had to hear lots of things when I started writing about it. People made me believe maybe I am the only one annoying the surreal sound of the community. It makes me so happy to see this day which I was crying out loud to happen for so long.

Wish you all good luck in this initiative. As for me, I'll go to carrier shop tomorrow to get a spare unit. :good:

Good to see this thread. My phone just died this night and since then is constantly hanging at boot screen. No access to recovery and download mode, no recognition by the computer (only a few seconds, then it restarts and gets disconnected) so no kdz flash via flash tool either. Just sent out a repair request to LG. Now fingers crossed it falls under warranty as I unlocked the bootloader. I purchased it in June and this is clearly of one of the first produced series which has the hardware defect, s/n starts with 505.

Don't worry, LG must repair this harware issue, no matter if BL is unlocked or not.
If you want to wipe or recover your data, try the freezer method. It works.

Then all of a sudden there up in arms being your friend about the issue. It really only took a two second google search to see how widespread this is. On reddit there's a constant stream of bootloop posts if that's not enough proof.
Now? It's just crickets from the ones who were so keen on shooting this off as a small 'problem'. foh

I have a backup on the sd card from just a few days ago. I was aware something is wrong as it started to have charging issues, so I made one to better be safe than sorry.

Good idea :good:
Unfortunately mine freeze too fast, I just had time to retrieve my data then wipe all via recovery.. now it's sent for repair.. :crying:

But I can't do anything before this issue occurs? My s/n also starts with 505...My only chance is to keep fingers crossed?:fingers-crossed:

Yo don't complain as your phone is working great, just enjoy it and keep in mind to backup your data to microSD/computer. There's a small percentage that it will brake one day.
I remember mine overheated few times, and it may have broke a hardware component.
If there's nothing to report on your device, then you don't have to worry.

Why? Nobody knows what serials are affected or the extent of the problem. Keep daily backups (as you should be doing anyway) and worry about it if it bootloops. Here's a hint - it probably wont.

I don't believe this at all. 602 was basically the newest revision anyone could quote at the time that LG "Acknowledged" there was a fault.
There have been reports of 603 units with the problem somewhere. (On either Reddit or this forum, can't remember where)
Given the way that LG are handling warranty claims and not honouring repairs for boot looped devices which are rooted or bootloader unlocked.
I think its way more likely that LG have just realised that most devices seem to take around 6 to 9 months before they fail, its easy to cost manage the issue by swapping them all around with minimal repairs until all warranties have expired.
I doubt they are making any new G4's now that the G5 is out. They will be hoping everyone who has a failed device with no repair options will just upgrade to the G5.
Those of which move to other suppliers would be considered acceptable losses.

LG has never acknowledged anything.
No need when they already replace any faulty device under warranty. Can't get a warranty then look for another device that comes with one.

If its bootlooping how can they even tell whehter its rooted or bootlooped. I've read accounts where they've replaced motherboards and returned the device.

I've got one, no problems.
Its dual sim and the number of people with dual sim i find complaining about boot loops is minuscule. Mostly the single sim lot. I'll take my chances.
Guess what, if mine goes south, i use warranty. If no warranty left, i'll buy another G4 with warranty at half the price i paid when it launched.
What am i going to do with those leather backs and cases otherwise

The never officially acknowledged anything hence the quotes.
They unofficially confirmed to android authority that there was a problem here:
http://www.androidauthority.com/lg-admits-g4-bootloop-problem-hardware-fault-669603/
Unlocking the device requires submitting the IMEI/DeviceID to LG which they can use as a warranty blacklist.
AFAIK an unlocked device advertises its unlocked status on the bootloader which is visible before the boot-loop occurs.
LG have a root checking service called RCT which logs the date and time of any root related files/binaries to the /persist partition and I believe it also sets a flag in an RCT partition.
It builds a log file of which exact root elements it has seen eg su binaries/ busybox binaries forbidden file extensions and the date/time it detected the latest one of these elements.
Simply enter the hidden menu and find the RCT option to see your devices status.
LG can simply disable the faulty cores on a boot-looping device and check any/all of these.
The best way to hide root that I have read on here is to fry the motherboard by applying 24v to the battery contacts. If LG did refuse to warranty though you have absolutely no chance of recovering from that.

Is there no way for them to detect this ?

Nothing is undetectable.... The post I read this idea from suggested that this forced the device into the Qualcomm recovery mode (most likely the flash chip can not handle the 24v but the lower level hardware can).
Given that the source of the problem is a faulty solder connection to the flash chip. this advances the problem past the faulty connection stage to the completely disconnected/shorted flash memory stage.
If they cannot boot/read the flash memory chip at all they have no way to prove you rooted. providing you didn't unlock your bootloader.
Obviously if you push it too much, physical damage like burn marks would be a giveaway of foul play.
I read one user had been denied warranty due to oxidation on the mainboard... given the faulty soldering and thermal issues this could cause oxidation/residue on the mainboard.
Another user was refused warranty because a warranty sticker was not present on one of the screws of his device. (This concerns me because my device has no such visible stickers)
I personally have a 506 device tied to a 24month upgrade contract that I started in Feb, I usually bootloader unlock and root within hours of unboxing but read about this issue first and have kept my device stock.
I'm hoping I do not get a boot-loop but think its a matter of when rather than if.

If they cannot boot/read the flash memory chip at all they have no way to prove you rooted. providing you didn't unlock your bootloader.

If you're not on a euro G4 BL unlock isn't possible to begin with.
Obviously if you push it too much, physical damage like burn marks would be a giveaway of foul play.

Right, this is what i was hinting at. You have to be desperate to try something like this which could end up forfeiting everything.

if you're on a contract then you're covered for the 24 months. Nothing to worry about.
yes there is no root. That unfortunately is the situation we are in, every brand has some unnecessary drawback or other.

Well unfort i got a sprint varient but no longer with sprint. Im sure lg wont fix mine if it did happen. I cracked my digitizer about 2 days ago so now the phone has its first sign of damage. And knowing lgs good for nothin high and mighty butts theyll tell me thats what did the boot loop. And for them hoping ill upgrade yea rite never again. Ive been using my old internation edition note 1. Just because its rooted and custom recovery. Id rather go old skool than deal with lg any more.

Plus i thermal paste every device ive owned back since my og evo 4g. So theyll know ive been in mine.

Also as for the waranty sticker mine didnt have one either

Just saw on the russian 4pda, 510 failed with bootloop as well

Have been wondering about the Russians as they have dual sim as well.
Do they have any poll to see which Russian devices had boot loop problems by serial#

The poll was there, but was removed 2 weeks ago, possibly new one will be back. Some ppl participated and answered that they don't have a bootloop, but later they had to change their vote and that was not possible... I don't remember the numbers, but the problem is also available on H818, many people go to the Service with it
BTW, in Russia / Ukraine only 1 year of warranty, so it's going to be interesting soon Mine was bought in Poland, bootlooped, now in service

It will be interesting if it starts again. I wonder why they removed it. Should have left it as is.
From the poll here, the ratio of devices with bootloop is highest with 505, fewer with 506 then keeps getting lower as the months go on. Yes there are some that have a problem but we don't know how many don't have a problem. They are quietly happy

1 year warranty in India too. 30k G4's imported. Number of Indians who complain about bootloop on xda ? can't find any. Why.
There have been other issues with earlier models, screen problems. One guy had the phone die. he said not bootloop.
Hong kong is another and Indonesia but again they say like you many, there is some noise for a month then it goes quiet.
But the single sim thread it never goes quiet.

With the help of google translate did a search on the LG section for the word 'butlup' (short for butlupnikov ) in cyrillic and found about 24 reports.
There is no pattern, only half of those 24 mention the serial#. Some earlier serials 505, 506, 507and some more recent ones 510, 601etc. The impression you would get is any number can bootloop which isn't what we found here.
Agree with what sergei says here.
In general, a matter of luck, like in any other phone. There is more panic, which somehow affects people. I, too, this fact forced to think about the choice of an alternative, but I did not find one, considering the price and characteristics. A camera for me is probably the most important point. None of the phone for the same price no camera, even close similar to G4 camera. The only option may be a Galaxy S7 / S7Edge. But twice the cost (comparing with G4 price) immediately makes to abandon its purchase.

WiFi Issue

Well i just got a brand new Moto Z2 Force and as I was setting up, i noticed the WiFi connection stopped working from time to time. I thought it was mi WiFi network, but issue was persistent on any WiFi network. I bought it on December 30, 2017
What I have done so far:
- Restore to its factory settings (didn't solve the problem)
- Update software 7.1 (didn't solve the problem)
- I took it to the carrier I bought it from, (They kept it for 12 hours to monitor its issue) (didn't solve the problem)
They told me, since its not a carrier issue, I should contact Motorola directly.
- I called Motorola support, and they told me that the phone needs to be sent to be repaired. Since its a common issue regarding WiFi and Bluetooth connectivity, what really pissed me off, was the word "repair", i explained that, why I should get a repaired/refurbished phone, since i pay full for a new phone and they explained that, thats how Motorola respect their "warranties". Repairing a defective device.
Since I live in Mexico, warranties here are a big pain in the ...
I know carriers in the US, have a 15 or 30 day, hassel-free return policy. But in Mexico, once you take it out of the box, its your problem.
Im pretty annoyed since I have the Moto Z Play and this phone works perfectly, thats why I went for the newer Motorola. Since I know how Motorola respects their warranty im never buying a Motorola again.
UPDATE
After going back and forth, the carrier decided that was a DOA phone and gave me a brand new one. I'm been using it for a week now and no issue whatsover.
Just some bluetooth disconnections from time to time, but i can live with that hoping for a software update fix.

Hi there!, calm down, i'm here to save you, but first off, i'm form Mexico too, and yeah, thw warranty here is some kinda tricky, but with Telcel you got the option between 30 days after the purchase to get a new one. But whatever, that time passed already.
Ok, first, tell me if you got the next issues:
Sudden disconnections
Horribly and stupid process to connect after a "breakdown" happens.
When you were connected (Luckiest thing ever), did you noticed that sometimes the speed goes like ZERO kb/s, it tooks like years to load an HD video form youtube?
If your phone shows all these sympthoms, welcome to hell, and i got some good news for you, the problem is not 100% the phone, for some reason, this problem starts when you update all the stuff form Play Store. So the phone is "physically" OK.
If you want further assistance you can send me a PM with your phone number, i'll be in touch shortly.
I'm glad to help you.

He’s not the only one with this problem. Would love to know your miracle solution!

I also have the same problem but it works PERFECTLY with 5 GHz Wi-Fi AC. Take a new wifi router

OT - I'm sorry, but this smacks of a scam. You don't need a phone number for anything, and if you have a fix, post it for others to use. What could be so secret as to warrant a PM.
I have had WiFi drops / performance issues with other devices with the same chipset, and it was fixed splitting the 5 and 2.4 into separate WiFi connections.

Hi there, first off, you have to turn on the phone in Secure mode - Long press "shut down" and then accept to turn on the Phone in secure mode.
Then, you have to test the wifi functions in this mode, if everything works fine, the problem it's not something about the HW of the Moto Z2 Force, but the problem it's a process which is causing this wifi disconnections, slow wifi etc..
Now you have to identify which process i scausing this, if you ask me, i've found that Google Play Services i scausing the problems, so i've tried many different versions and now it's working great, no wifi disconnections, FULL speed, and no other problems.
Let me know if i can help you out with more information, sometimes it's hard to write through a phone jaja.

Please check out the fix i wrote in other comment, hope it works for you.

Wanting to file class action lawsuit
Well it's as plain as I can make it; after attempting to contact support for help with my Z2 Force's WiFi issues; which go figure I find out is a known issue since DAY 1. They won't fix it because the warranty ended 11/18/2018. I explained I found over 17 pages on just Lenovo's website of issues and Motorola and Lenovo did nothing. They still won't do anything they want 150$ to look at it and then they may give me a replacement z2 force. I've had enough I am starting the process of a class action lawsuit against Motorola; and Lenovo and I wanted others to reach out to me. If you've had issues please contact me. Thanks
Rob

My s z2force (1789 05) sometimes disconnects the network (including wifi). When playing games, it is usually used. I feel that this is not a big problem. I was on a lg v30. This problem is more serious.
