[Q] Wi-fi connectivity issues - Nexus 7 Q&A, Help & Troubleshooting

After a recent snafu in trying to remove root from my Nexus 7 tablet and installing the 4.3 update I think there are issues with with it's ability to keep a constant wireless connection, Juice Defender be damned as way before root and even during root I was able to maintain a flawless connection although I think the issue may have arisen during my installation of a cracked google play store app.
This was a couple months ago though.
However I decided rooting wasn't worth it and wanted to update to the new 4.3, this is where the snafu occurs, unrooting wasn't a problem at all, nor was flashing stock recovery, but the process of installing 4.3 was since even performing the update in my settings wasn't working, it would download and my tablet would restart and try to apply the update but soon after it would error out and I had to perform a hard shut down.
After that it would boot like normal and there were no issues, other than the update failing to apply.
So I decided to try and apply the update manually and as it turns out, I was attempting to install the update for the mobile version of the tablet instead of the wi-fi only one that I have so it didn't install correctly and simply erased all data on my tablet except luckily for the devices fastboot mode.
Seeing that I installed the correct 4.3 factory image and this is where the wi-fi issues come into play (I wanted to explain in as much detail as I could that might shed light on my current wi-fi situation).
The tablet booted up seemingly normally, taking a bit longer than it should have to me and upon getting to the glowing X before the main screen it suddenly reset it's self and then booted up correctly; so I finished the set up process after linking my wi-fi up but while going through each app that uses wi-fi I started off with games like Happy Street and The Sims Freeplay which worked normally.
Then I got go my Bank of America app and it's the one app (besides the Play Store on occasion), that didn't work at all, instead it just timed out, there's a screenshot so you can verify for yourselves.
You can clearly see I do have an established connection but this is the only app that fails to work after the update, again besides the Play Store but I've removed root and the crack is no longer installed, not that it would work anyway without root access but it doesn't concern me as much since it'll connect after force closing the app and starting it again.
So that's my issue in detail, is there something that I messed up that's preventing the device from maintaining a connection? Or do I simply need to re-install the factory image to restore connections?

Hmm...I've been having some trouble with WiFi as well.
I was running CM10 and then installed the 4.3 factory image over that. That's where the problem started. Since then I've tried the 4.2 factory image, Ubuntu Touch, and I'm now back on CM10, but the issue remains that my WiFi seems to stop working even though the icon in the notification bar says that it's connected.

Well the weird thing is, is that every other app seems to work but that one where it just times out, I'm going to try just re-installing the update and see if that helps things.
Edit: After backing everything up I decided to re-install the 4.3 update and after downloading the Bank of America app it started up instantly, froze for a moment and allowed me to sign in.
I closed out of the app and tried again to check and after 3 attempts to sign in it worked each time, I think the re-installation did the trick.

[Q]Network connectivity & Dexter's mod 1.41

Hello,
I would have posted this under the development posts but the forum won't allow me to...grrrr.
Anyway, I am using Dexter's mod 1.41 with the display settings fix also installed. Everything works great.
Except...I keep getting network errors whenever I try to download an app from the official marketplace, I also get them when sync'ing my dropbox, trying to download from the appoke apps store, signing into twitter, and a number of other apps. My browser works fine. Sometimes I can reboot and it starts working fine and then a few hours later I start getting the "network connection error has occurred" message from various apps again.
I did try reinstalling 1.41 & doing a complete wipe/restore after & still had the same problem eventually. It worked fine for awhile as I was able to go to the marketplace and download all of my apps again.
Anyway any ideas?
Thanks in advance!
i might ask if your network problems occur after the tablet was recently asleep. it seems, at least latest stock, that the power profile is set to sleep wifi/network connections when the display is off.
you might want to wait 5-10 seconds after waking up, or i suggest putting the power control widget on your homescreen and tapping the wifi button twice to re establish your network connection if you're getting network errors.
worked for me when i had download/network errors.

Yeah Forgot to mention that, but no its random when it starts happening. But definitely not just when it has been just woken up.
Nevertheless I am going to try what you suggested. I couldn't at the time when I wrote the post as it wasn't working. I turned it off and removed the SD Card, mounted it over on my PC, then copied your recent ROM update as well as Elocity's most recent firmware update, put the SD card back in, tried to reboot into recovery mode but for some reason it went into a normal boot. When I unlocked it, for some reason was asking me to sign into Google just as if I has flashed it but I definitely didnt. I've done that a bunch of time, this was definitely a normal reboot with dexter's 1.41 mod still installed. I canceled out of the google login after waiting 10 min for it to connect to Google's servers. (it was connected to my wifi network or at least I had the icon with the bars indicating I was connected to wifi) When I got to the main screen it started working normally. I went onto the market and downloaded Angry Birds Rio. Plus there were a bunch of updates for my other apps. So it is almost acting like I was not previously signed in with my google account, except that I did not relogin since I canceled it before finishing. Also I dont imagine that Dropbox would have been affected as it has its own login. But that is working fine too once I re-logged in.
It does seem to be intermittent. If it were the "not connecting after coming out of sleep mode" issue wouldnt rebooting fix that when it happens? I try that everytime I get the network errors and it works maybe 25% of the time.
Thanks for the response!
Did the 1.41 install and three patches also. Display still FC all the time. other then that works OK!.

Issue with [ROM][JB][AOSP] Lenovo Ideapad K1

Just a head's up...
I installed this ROM 2 days ago and it was working brilliantly until last night. My K1 powered down (assuming battery died...) and when I was finally able to get it to boot up no applications would work:
Upon booting I received messages that App Store is no longer working, Swype Beta is no longer working.
I attempted to open Scramble (Zynga game) and it force closed.
I attempted to open Facebook, and while it remained open, it would not connect, despite a good WiFi connection
I did a factory reset and got a notice that root may have been lost, so I elected to repair.
At the point where I tried to connect to WiFi as the first step in setup, the system apps started crashing.
I'm re-flashing now to see if that does any good, but wanted to make a note somewhere that this ROM may not be as stable.
Unfortunately, I can't post this reply to the DEV forums because I'm a noob.

[Q] My phone just freaked out!

Today my GS5 started freaking out. I cannot install or update any apps from the Google Play store - they all get stuck at a certain percentage of the way through the download. Each app has a different sticking point (22%, 39%, 75%, etc.), but each app sticks at precisely the same percentage every time. At the same time, my wifi has gone completely bonkers. If I turn on wifi, it will connect to my home network like normal, then drop off without warning, then get back on, then drop back off, etc. every few seconds. If I go into the wifi settings and observe while this happens, I see the message that the phone will connect when the signal is stronger...but if I look at the details, my wifi signal shows as Excellent strength and 100+Mbps speed! The phone is warmer than usual (though not hot) and battery is draining faster than usual, but that's probably to be expected given what else is going on. The wifi network itself isn't having any noticeable issues with any of my other devices or laptops.
Both of these things began happening at the same time, but I'm not sure what triggered it. Everything was working correctly this morning, but sometime this evening everything blew up. I uninstalled all apps that have been installed in the past few days anyway, but the behavior persists. I am not rooted, and I have not yet upgraded to Lollipop. I have rebooted and cleaned the app cache several times, and there is at least 3GB of free space on the internal partition (and far more on the SD card).
I don't even know how to trouble shoot this! I would be most grateful if someone could give me some guidance on how to resolve this. Thanks!
Just a few questions. What OS build is your S5 running? Is it rooted? If it is rooted are you running any Xposed modules or have any apps that might have caused this?

I'm running 4.4.4 (see screenshot), not rooted. I have not (to my knowledge) touched any Xposed modules. Any apps that might have caused the problem have been uninstalled (unless I accidentally missed something).
Just FYI for anyone else who might be having these issues...I think we have some answers. After some testing and other suggestions, it looks like I have the 5.0 firmware but am still on 4.4.4, and that discrepancy appears to be causing the freakout. I assume Verizon pushed the new firmware during a reboot over the past couple days because I certainly didn't do it intentionally (and I have no plans to upgrade to 5.0 Lollipop anytime soon, either). However, by unselecting the Smart Network Switch functionality, it appears the wifi is behaving itself again and all is back to normal. Thanks, Big Red.

Overheating/Bootloop/Black Screen problem solved but...

Hey, I had been stuck with the issues as mentioned shortly after I upgraded to Nougat via ODIN (SM-G935F/probably Netherlands, Unlocked, no root, no mods). The phone would work fine and then suddenly start overheating and resultant bootloops and black screens when in certain standard apps like Google photos and Facebook. This would happen with no fixed pattern, sometimes everyday, sometimes once a month). I did cache clears and full resets but the problem would reappear. Phone stopped getting OTAs as well, although it got a few in the beginning. Security patches. Recovery typically showed updating and didn't progress.
Finally I decided to flash another latest stock ROM via ODIN. Now a few days have gone by without a sign of the previous troubles (God, I hope it stays like this).
My question after this long story, is this possibly a hardware problem, in which case I'll sell it off before it reappears. Or could it just be a software glitch solved by the new ROM, in which case I'd like to keep the phone. Which is more likely, I really want to keep the phone as the S8 upgrade is not worth the money for me, in my opinion.

Sounds like a bad flash. The new flash removed the issues, so you're good to go.
Guess what guys, the problem returned after about 3-4 weeks. Appeared randomly while using FB. Phone went into bootloop and overheating again, and even when it restarted properly, it would go into the same cycle when I started using apps like messaging, whatsapp and facebook.
I booted in recovery and cleared the cache after about 25 reboots. One thing I noted was that recovery initially showed an update running, which got stuck first, and then completed after another reboot and entering into recovery. Has been stable for the past 24 hours now, like it never happened. I can't figure out what the issue could be, since now I can do whatever I want and it won't overheat like before or reboot.
Feels like a software issue since it disappears like it was never there. Hardware rarely does that. Is there a possibility that storage of some sort is bad at some point, and when data is written over that point, the problem appears. I'm shooting in the dark but can't figure it out otherwise.
Yup.
Seems you have memory issues.
Go to Samsung service and replace memory chip.

Phone automatically installing unwanted apps!

I just traded my sprint lg v20 for this verizon lg g6 vs988 yesterday because I needed a gsm unlocked phone. Now I finally got a phone my son card works in but I've been up all night trying to fix this issue.
Seemingly at random the phone just starts installing "random" apps that I've never used before. Some of them include
Go90
Wish
Yelp
Yahoo mail
And several others I can't remember at the moment but I'm sure ill be reminded soon. I keep uninstalling them and they keep coming back. By the manner which they are installed on sure they are not normal bloatware. They download silently in the background even while I have an active foreground download going.
I've googled the issue and found no resolution. I also noticed the phone charges ridiculously slowly. The phone was also on an outdated firmware with a security patch from 2017. The built in system update would not detect any update for the phone. I had manually download and install the latest update on the computer last night.
After doing this with a completely fresh factory reset these apps were still installing themselves. I then used verizons pc upgrade assistant again and did a firmware repair but skipped the phone backup step so I again would be starting fresh. Again these app's keep installing themselves.
It seems to be on some kind of interval. After so much time that the phone is running it suddenly install another random app or apps I've never heard of before, then after so long all of a sudden some more different apps suddenly appear.
I also tried malwarebytes and of course it says nothing is wrong. Can someone please help me get this sorted?
Which firmware you have?, maybe it would be the best to flash clean stock firmware with LG UP.
You can find latest kdz here..
https://lg-firmwares.com/lg-vs988-firmwares/
16a download via verizon upgrade assistant. Would reflashing the kdz via lg up do anything different than verizon upgrade assistant?
Ps I had to retype this message 3 times because half way through typing chrome just shut down for no apparent reason.
Finance
Groupon
EBay
Were can I download latest version of lg up. I only found one old for g4 and one that said 1.8.8.0 but wanted me to login.
Suspicious. What I do to prevent problems like this is to disable all apps possible, including googles apps and the Play store crap. Then go in to each app within settings and deny data access to them, clear the data and deny all hardware access that makes sense. For example, Groupon would not need microphone access so that access is removed. I think only the Contacts app has the phone permissions. It takes some time, but worth it. Reboot after you are done and re-check because sometimes the settings don't seem to stick. Maps will still work without Google Services. Using Android_x86 in a VM, trusted apps are downloaded in a virtual machine and then put on the sd card and then installed on the phone. I'm not a very trusting person Its suspect that the "Emergency Alert" app has access to everything and I can't deny microphone or any other access for it.
I think it may have been the app named "app flash" that was doing it. Its apparently the app verizon added that by default sits on the left side of the home screen. I disabled it from my home screen first while setting up my phone after reset but left app flash active. Its supposed to be some kind of assistant app that recommends apps to install and acts as a hub for all your other apps.
So far I haven't had anything else auto install(nothing visible anyways). After uninstalling all the 10 or so apps that were installed they haven't come back yet. Hopefully it stays that way and nothing malicious going on in the background.
Anyone please link me latest lg up? Still like to a complete fresh firmware install just to be safe. One that will completely wipe everything and install the os fresh.

Both my wife and I have had that happen. The apps we got were Big Farm, TMZ, and some other crappy game.
Our phones are unlocked and rooted, so I immediately did a bare-metal refresh - wiped everything including system and internal storage, and did a complete stock flash from recovery. Since then we have kept "Install from unknown sources" and "Auto-update" both set OFF, and have had no further issue.
