No calls, home and recent apps button won't work - LeEco Le Max 2 Questions & Answers

Hi guys, this morning my father's Le Max 2 (snap820, 4/64) stopped receiving calls, and both the home and recent apps virtual buttons decided not to function, too. Strange enough, I'm able to long press them and get the action I'm supposed. Any ideas/fix? I've already checked the phone for malicious apps and misconfigurations

Hi, I have exactly the same issue, plus I cant download any more applications from play store. Can anyone help?

If you have a backup taken when the phone was working well, I'd suggest you to restore it. If not, try another ROM, or at least a different ROM flavor (if it had an EUI based ROM, use LineageOS and viceversa). If that doesn't work, you may need to get into Qualcomm recovery mode and flash the developers ROM to get the phone to a real factory state.
But first, try to revert to factory settings from the current ROM, and see if that solves the issue.
There are several threads here with info on how to apply the above solutions.
If none of these solutions works, and you still have warranty time left, you may want to contact the seller for a repair or replacement.
Good luck.

Do the notifications work?

I was on holiday, so no PC I could use for flashing or else. A reset from the settings worked, still don't know what caused the issue sadly

I couldn't find the fix for this in any other threads, can someone help a not-terribly-tech-savvy person with a fix for this

Today I also had a same problem. So just I backed up all important data's and done factory reset. Now everything works fine.

Everyone have same problem at the same time means the ROM has virus or Trojan.
What is the ROM everyone is using?

Camera unable to start

I recently rooted my One and had networking issues so i flashed this rom ( http://forum.xda-developers.com/showthread.php?t=2266025 ) and after flashing though the networking issues were fixed it then had issues with the back and home buttons, as the phone did when i purchased it, so i located and installed the ota patch that tmobile had pushed to fix it, and there was an error installing it, but the buttons were fixed anyway, but now my camera app does not work, i can open it and see nothing but black, the apps buttons do not appear to respond and after some time i get a "unable to start camera: error. i cannot locate a apk or anything similar to try to reinstall the camera app, other apps i launch tell me "error accessing camera", any help would be appreciated
Update: just discovered, the light does not work either
fixed issue by flashing a different rom and flashing back
i had the same problem
I never actually solved it though. It happened when a replacement was already on the way so i didn't bother trying to fix it. I did research a little and came across a few people that said a bad kernel flash could cause this. I was running the stock kernel and stock rom, and it was working just fine before the OTA so i figuered it was probably a hardware issue. If i were you i would try flashing another kernel. If doesnt work call up tmo and they will probably send you a replacement(you can also contact them through the live chat the on the website, much more convenient in my opinion). I had blown speaker and they didnt even ask about unlocking the bootloader or root, i assume it is because it was clearly a hardware issue. If you figure it out, please share.

Of how WiFi won't turn on and I don't know that I'm doing - Galaxy Grand 2 G7105

I got my hands on a Galaxy Grand 2 sm-g7105. Performed a factory reset from device and the system worked nicely enough. A particular third party app I wanted to use wouldn't load so I kept tweaking.
I rooted and set up a CWM recovery with Odin, then considered going with Resurrection Remix. I made a backup with CWM, wiped the device and set it up. It looked great but 'audioFX.apk' or something along those lines kept crashing every 30 seconds or so. It didn't cause me any problem besides the annoying crash notification, so i figured I could just remove the apk and be done with it. To my dismay, then the notification then piled up non-stop and the system become unusable.
I went and restored the backup on CWM. Then I'd get error notifications for this and that stopping working (basically the apps present on the backup that weren't on the stock rom), so I figured the backup was useless. Another mistake, I guess.
Performed another wipe, deleted the backup for space. Tried removing every piece of bloatware I could find before unrooting (I wanted to do that). Finally everything seemed to roll... except I deleted some important apk, SecDownloadManager I've come to believe, and at that point the Play Store couldn't update a thing, it got stuck on 'Downloading'.
So I did another wipe, just to find out that didn't restore the missing apks. Got my hands on a stock rom for my model (a different build than my origibal one, but to hell with it... right?). I got that working work Odin, but to my surprise that didn't seem to completely restore the apk mess, and I got a ton of crash apl notifications and even after logging on Google the play store didn't let me in to try and see if apps could update.
Finally, I found what is supposed to be the device's original rom. Odin'd it all the way. Everything seems to be where it belongs, but I cannot really check 'cause... NOW THE ****ING WI-FI WON'T TURN ON. It's not like it doesn't connect to my network, it just won't activate. I press the switch, or goes back off.
I tried rebooting, taking out the battery for some seconds, performing a factory reset from within the system, wiping from CWM, dialing *#0011# to access service mode and deactivating power-saving mode. Nothing works.
HELP, please.
I'd be happy if the WiFi just worked, but knowing why the hell a stock rom should give any headache or what I'm doing wrong for it to go so wrong might be a step towards the solution.
PS: I'm writing this as I recall, so the details might not be completely spot-on, but the broader problems were those.

screen sleeps every time i try to use the phone

Galaxy S III 19300 has developed a problem where every time i try to use the phone i.e press power button and then swipe, the screen sleeps, Sometimes it sleeps after 10 seconds sometimes before i even swipe. Factory reset done, have now rooted it, but need to ascertain if it is a hardware failure or bug. I managed to set time out for the longest setting and obviously usb debug mode but wonder if its a power issue or gpu or driver issue etc.... please can anyone help?
Hopefully you're still on a stock rom.. Theres a ussd code to bring up a test app. You'll be able to test the proxy sensor etc from there.
If everything seems OK or if you have a custom rom then you'll have to download the firmware and odin on a pc and flash the phone back to stock. You'll need to flash the firmware, factory reset and flash again. That way you know there isn't any remnants left over from the last time it was used/flashed/rooted. This is the only way to find out if it's a hardware or software issue without all the faff.
Beyond not having the phone in my hand that is the only advice worth giving. If you keep chasing shadows you won't find the problem. Best to nip it in the bud.

Hi, thanks for your response. Yes i'm still on still on the stock rom and do not believe it was ever flashed/rooted. I will take your advice and try your suggestion. Where would i find the USSD code for the test app?
Dial *#0*# for the diagnostic screen.

Can't fix Bugged custom ROM

I have a Galaxy S III GT-I9300 I bought in 2014. After three years, I downloaded a custom ROM from xda-developers (android 4.3 is all I remember about it) and installed it successfully. It worked alright until one day when I wanted to sell the phone and a customer wanted to buy it on short notice, and I rushed to delete my files from the phone, but I destroyed the Android... I connected it to my laptop and shift-deleted some system files.... since then, the phone is delaying when trying to unlock (if i lock it now and try to unlock it a few times, it opens harder and harder), when I'm using apps it continously shows that some .com processess stopped working, and if I try to turn on the bluetooth, the phone instantly freezes and restarts itself.
I tried reinstalling two original ROMs, (version 4.1.2) successfully, but the data on the phone&the system problems remain the same.
I'd like to know how can I make a hard reset, meaning in deleting all the files&settings as it was brand new, just to clear everything, like clearing CMOS. I also think the recovery mode is damaged and I'd like to fix it somehow (if this is possible). The installation process I did for installing the custom ROM from XDA-devs was long and complicated, I had to do a lot of things... and I just want to get the phone fixed and restore to default (or even to fix bugs on this android version) its android, kernel & everything could be ,,reflashed''.
I'm willing to pay if someone helps me fix the problems and it really works. Thank you!
