[Q] Android 3G

Ive been tossing the idea around on whether or not its something to pursue. In my mind it seems somewhat feasible. I currently have a Samsung Galaxy Player 4.0 (which from what I can tell is basically a Samsung Galaxy S without a data plan through a carrier) and it is rooted. There are even start-up processes and services for the dial pad and phone (even though its only supposed to me a glorified MP3 player). So with that being said here is my idea...
The original Amazon Kindles came with free 3g connectivity right out of the box (no service plan). I am thinking maybe there would be a way to set up the Galaxy to connect to the Kindles free 3g internet. Maybe mock a Kindle ID to the Galaxy. Even if you did something along the lines of running a Kindle ROM in a VirtualBox type app on the Galaxy for server authentication.
What do you guys think????
I am new to the Android world but not new to computers or hacking (by hacking I dont mean black hat. I mean modifying things to suit your needs ie. rooting).

The Galaxy Players don't actually have a cellular baseband. The package's position on the board isn't populated. Thus, it's completely impossible for the Galaxy Player to connect to a cellular network.
The reason the phone and dialer bits are still present is they are core to Android and can't be removed easily.

ok what about tethering the kidles 3g to wifi???

The Kindle's 3G is only usable to download books. The connection is very restricted, and you really can't do anything with it. Obviously, if the operator detects excessive traffic on an account only intended to download eBooks, your access would be killed pretty fast.

4.4 (KRT16S) WiFi problems

Hi,
I'm having WiFi problems, let me explain the situation:
A few days ago I got the 4.4 (KRT16S) OTA update, let it update, almost all was working fine, but as Android goes, some features were missing when you update (like the Storage Access Framework file picker, it just wasn't active and a few others).
So I factory reset the device (please note I have it completely stock, no root, no unlocked bootloader etc.), after it did it's dirty job I logged back into my Google account and it started to restore my previously installed apps. All fine so far.
After opening Google Play store there were all the images missing and a message telling me that I have no "network connection", which was funny because I could traverse the store, install apps, but just no images.
Next was the Google+ - again telling me I had no connection, the same Google Music, Hangouts and every other third party app that somehow uses (imho) the Google Authetication/Account were reporting errors. On the bright side, gMail/Authenticator/Gallery/Photos were ok... Rebooting the device did not help.
As it was quite late I said "screw it" and went to bed. What was my surprise the next day after logging into the compay WiFi that it works like it should, no errors whatsoever. So I thought "ok, it just needed some time" (whatever that would mean :silly.
After I came back home, logged into my WiFi and again - the same problems. I tried meddling with the encryption modes, even opening it completely, turning off QoS, lowest speed modes, changing channels (not that would help, but I'm desperate ) etc., but to no avail.
Please note that it worked on "before the factory reset" KitKat, 4.3 and 4.2 Jellybean, also Transformer Prime and HTC Wildfire S (bunch of different roms and versions since I have them) are using that WiFi with no problems.
Anybody having similar problem? Is there a fix for that?
Thanks for your time
EDIT: The WiFi connects and most of the apps work, it's just some of the Google apps that do not: Google+, YouTube, Play store/music, Hangouts and some others.

how old is your router? Does it support 2.4Ghz or 5Ghz? In Wifi, select "Advanced" and select the frequency that your router support.

I have this one, not that old, but still only 2.4 GHz:
- D-Link DWL-2100AP
- http://www.dlink.com/-/media/Business_Products/DWL/DWL 2100AP/Manual/dwl2100ap_manual_EN_USA.pdf

Update: Well...somehow it fixed itself after a while (day), the only permanent change to my WiFi settings was changing the channel and SSID...no idea what's the reasoning behind this, but I'm glad it's working now

The problem is DNS related - once I set Google's DNS (8.8.8.8, 8.8.4.4) for my home WiFi on the phone, all the problems were gone. Fixed the problem on my N4 KitKat and another user's N7 KitKat with completely different AP/router.
Weird - all the other devices have no problems with my router's DNS (different device than the AP). Hope that helps somebody who has the same problem

[Q] Wifi Slow on Galaxy S5 - Strange Issue, Please Help

Hi All,
I was wondering if someone can help me. I am having a bizarre problem on my Galaxy S5, which so far has stumped Verizon, Samsung and Time Warner Cable Tech Supports.
For some reason, when I'm connected to my home Wifi network, certain apps run very slow. Basically, if you open an app like Facebook, Instagram, or the Google Play Store, a lot of the icons, pictures and thumbnails all show up gray, and either don't come up at all, or take forever to load. As soon as I turn Wifi off and switch over to 4G, they all pop up almost immediately. I've also noticed this problem on Google Now. You tap the microphone, say a command and it gets stuck on "Recognizing..." for a long time, and quite often comes up with "Can't reach Google at the moment." Again, it's only certain apps. Other apps like my web browser app don't seem to be affected.
This doesn't make sense to me, because I also have a laptop and my girlfriend's Galaxy S III connected to my Wifi network and they don't have this problem. I've even busted out my old LG Spectrum 2 and sure enough, these apps load up lightning quick on it. I've done an internet speed test on my S5. On my Wifi I get a 19ms ping, download speeds of 18 MB/s and uploads pushing 2 MB/s. When I'm on 4G, the ping is 40ms, and the speeds are only 6MB/s and 0.7MB/s respectively, so the Wifi theoretically should be way faster.
I spent over an hour on the phone with Verizon and Samsung Tech Support, and after trying a ton of different things, including a Factory Reset, they determined it was probably the device. Since I'm under warranty, they sent me another one. I got it yesterday and tried it...yep, same problem.
Just out of curiosity, I tried it on the Wifi at my workplace. Wouldn't you know it, the problem isn't there. But, I don't understand what could be wrong with my home Wifi. I've got Road Runner Turbo internet from Time Warner w/download speeds up to 20MB/s. I've also got a really good modem/router that cost several hundred dollars. And, like I said the problem doesn't seem to happen on other devices.
I've searched the internet and have found almost nothing on this. Does anyone know of something I can try? Here's everything I've tried so far:
"Forgetting" my Wifi Network and Reconnecting
Resetting the Modem/Router
Clearing Data and Cache on Affected Apps
Phone Factory Reset
Trying with another Galaxy S5
Switching from DHCP to Static Connection on Phone
Switching DNS to Google's Addresses on Phone (8.8.8.8 and 8.8.4.4)
Tinkering with the Modem/Router Security Settings and even Disabling Security
Changing the Router Bandwidth Settings
Changing my Router's Broadcast Channel - Have Tried Several Different Ones
Calling my ISP and Upgrading to a Higher Bandwidth/Speed
Here's my hardware details:
Phone - Verizon Galaxy S5, Unrooted, Running Stock Kitkat 4.4.4
ISP - Time Warner Cable, Road Runner Turbo
Modem/Router - Motorola/Arris SBG6782-AC
Thanks so much in advance!

Watching with interest.
Have a similar situation with my s5 900f international running latest NeatRom.
Some days better than others even when using home sky fibre optic and no drop in speed from router.

Had to get a new router
Ok, so I finally fixed the problem...in a manner that I wish I didn't have to resort to, but it seemed like the only option.
Let me start by thanking Rukbat from Android Central. I posted this topic there too, and his response was very helpful. Here's a repost of it:
Talk to Verizon (the tech people in the back, not the sales associates) or the Time Warner people (same thing - tech people) and see if anyone has an old Linksys or D-Link wifi router you can borrow for a day. (I'm using a Linksys WRT54G at the moment, and in router years it's as old as George Washington's corpse.)
From years of experience, writing communications code, playing with my phone, routers - and looking at my calendar - I'm guessing a bug in KitKat that shows up only with some apps. My almost new Linksys EA4500 started showing this problem almost as soon as the phones updated to 4.4.2, but the apps all work fine on old routers.
If an old router solves the problem, you can get a refurb WRT54 (G or GS) for the $25 range on Amazon (or maybe TW has an old one they'll let you use with one of their modems).
The Facebook app works just fine on mobile data, AT&T hotspots, TMobile hotspots - but not on new Linksys (supposedly the best) routers, and I've heard reports of the same problem on the newer D-Link routers, also supposed to be top-of-the-line. (I actually left the app running for 12 hours once, just to see how long it would take to update. It's more than 12 hours, because it still hadn't done anything. But standing in the parking lot at a Sam's Club, with a barely usable AT&T hotsopt signal, it updates in a couple of seconds.) AT&T connected me to their in-store wifi (which is secured, so of course they deleted the connection after we checked it out) and Facebook updated immediately. Speedtest.com shows over 14mbps download and pings running from 15-50ms with my new router that doesn't work with facebook, so it's not the connection, it's not the wifi signal itself, it's either a problem with certain apps or a problem with the 4.4 wifi firmware. Play store downloads are slower on the new routers too, but not too bad. just noticeably slower. (If I set up a guest account on the router it works fine, though, so it's not a bad router. It's just a pain to have to sign into the guest account every so often.)
This is the reason systems analysts turn grey at a young age and have bald spots. Problems that don't seem to make sense, and people in a position to debug them who can't or won't. I can reproduce the problem at will (which is the difficult part of fixing a problem), but there's no one interested in fixing it.
I ended up just getting a different router, as he suggested. From what he's describing, it sounds like some routers just don't play nice with some newer phones, for no apparent reason at all, which is both discouraging and frustrating at the same time. And I've come to the conclusion that my router is one of them. After spending hours on the phone with technical support from Verizon, Time Warner, Arris and Samsung, no one could find a solution for me.
I will say that I did find some hints from other places online that tweaking certain router settings will fix this problem, but I think I kind of nipped myself in the **** by not doing my homework when I bought my Arris modem/router. This router is locked down pretty tight from changing certain settings. You can't disable IPv6, which some people say fixed the problem. Someone else suggested enabling IP tunneling, but I don't see this setting on my router. Somewhere else, I read that this is the same thing as Port Forwarding, but I really don't know what port you would have to forward to a phone. You can't even update the firmware on my router, as Arris only provides it to cable ISPs...and they won't push it to customer owned devices. I don't even know why they sell this model to the public if that's the case.
So anyway, I just bought a much cheaper Netgear router from Best Buy, and wouldn't you know it, it works great! I think that it even outperforms my Arris. I guess the moral of the story is be careful about what you buy.

Update - problem solved!!!
I cannot believe this. I managed to get my phone working yesterday with my old Arris modem/router. I didn't even have to tweak it, or try to disable IPv6 or anything.
It turned out that the problem was my phone's SIM card. When I first bought the phone, I ordered it online and I remembered that it came in the mail with a SIM card. But, when I placed the card in the phone, it wouldn't activate. I probably should have called Verizon at that point to ask what I should do, but I ended up just taking the SIM card out of my old LG phone, and putting it in the S5. It looked the same to me, so I didn't think it would matter.
Then, not too long ago, I noticed that certain apps were saying that I needed an "Enhanced SIM Card" to use them, so it got me thinking, maybe I should have used the card that came with the phone. I called Verizon, and sure enough, they said that the card that came with the phone used much more updated technology, which is a better fit for the phone. So, they got it activated for me, and now not only do all of my apps work, but the slow Wifi problem is gone too! I didn't even know that the SIM card can affect Wifi. But anyway, this is great! I can take my new modem back, now.
I would ask anybody who has this same problem if they are not using a SIM card that came with the phone. If you are, it could be that you need a new one or more updated one. I believe most carriers will give you a new one for free. You can also check to see if your card is outdated in a couple different ways. Try opening an app like Softcard, and if it says that you need an Enhanced card, then your card is outdated. Also, check the numbers on your SIM. According to Verizon, in the US, the card should have a handful of numbers, followed by FIVE zeroes. If there are any more than five, it is an older card. It might be different for different countries or carriers.
Hope that helps!

Grrrr....spoke too soon. It worked fine for about a week, but now it's doing the same thing again, even with the new SIM card. Switched back to the newer router. Guess it's something with the Arris router after all.

Set restrictions on S8 similar to those found on iPhone?

I am going to be blunt...some friends of mine are having some issues in their marriage due to one of them having a porn addiction and also just using their phone too much so they came up with 5-10 apps they want to be able to use and don't want anything else to be usable including browsing the internet. Being their most tech savvy friend they turned to me for help.
He had an iPhone 6S Plus and it was very easy to set it up to lock down apps and even prevent web browsing even if he did manage to get a browser installed via Restrictions.
Unfortunately his phone recently died out of warranty and his wife had an old Galaxy S4 anyway so was due for a replacement. Their carrier (T-Mobile) had a special on Galaxy S8's for a buy one get one free so they ordered two of those to replace his non-working phone and her old one. (not relevant to the question, but I also have T-Mobile and took advantage of that deal too)
I have tried and tried to find a way to do those things they want on Android but am not having any luck. Most of the stuff I see for Restrictions on Android are for people wanting to put THEIR phone in like kid mode prior to handing it to their child. Other apps like Norton App Lock work for some apps but not all apps are listed and for example doesn't allow restricting the built in internet browser.
Any suggestions would be greatly appreciated.

I would download applock from the Google play store. Let's you lock apps and then a pin is needed to unlock. I use this one

Accidentally sideloaded verizon full image

So I was rooting my Google store bought pixel 4 and missed a step. Needless to say I had to sideload a full ota to recover it. But I'm pretty sure I accidentally loaded the verzion version. I got all the verizon apps that showed up when I rebooted the phone. I went back and wiped everything in recovery mode and tried sideloading QD1A.190821.007.A3 and it keeps erroring out. This is the firmware that Im 90% sure what was on my phone. Is there a way to get back to factory google store firmware or am I screwed now? I am on a verizon sim but phone was bought on launch day from the google store. Its also noted that I am currently on QD1A.190821.014 firmware. This doesn't appear to be the verizon firmware.

The Verizon apps appear not based on which ROM version you load, but instead based on whether you have a Verizon SIM in the phone during setup.
If you loaded the wrong ROM onto the phone, you may not be able to recover by sideloading an OTA. You should be able to recover by doing a complete reflash of the image you want (the image version, not the OTA version).
What error is it giving you?

I cant remember the exact error but it would error out about 45% through the flashing. I am currently running QD1A.190821.014 which appears to the google FI, T'Mobile firmware. I still have the ability to turn OEM Unlock on in my settings, so it appears I am ok. I just wish they had better wording on which firmwares for the unlocked ones form the google store and others.

Regarding loading the wrong one, I did the same thing because the December update had a discrepancy between the announcement and the download page about which rom applies to which phones. I switched back and forth between QQ1B.191205.011 and QQ1B.191205.012.A1 before they finally corrected it, but everything worked fine on both versions as far as I could tell.
About the Verizon apps, if you're on Verizon or one of its MVNOs, if it installs other stuff, you'll want to leave it. Don't confuse My Verizon and My Verizon Services. My Verizon can be uninstalled, but if you mess with My Verizon Services, you'll end up losing things like wifi calling.

That's not true. You can go to all apps and show system. MVS can't be deleted without root but you can disable it with no adverse effects. They can't get into your device to see what you have installed and when you installed it, but who wants to give them that info anyway?

As of Android 8, disabling My Verizon Services doesn't permit wifi calling because it depended on that application for that functionality. It's hard to remember what else was troublesome, but I thought there was something else which didn't function once it was disabled.
I don't have wifi calling anymore on Visible, and I never used Android 9 because of the wifi scan throttling mess anyway.
Would you mind checking that your wifi calling works on your pixel 4, disabling My Verizon Services, rebooting, switching on airplane mode, then enabling wifi only, and then try making a phone call? I'm interested to know if that behavior has changed. Thanks!
Here's some more information. It certainly seems true for others as well:
https://community.verizonwireless.c...ng-since-Android-8-update/td-p/1042025/page/2
And many other XDA threads correlating the two:
https://www.google.com/search?q=sit...69i57j69i58.6651j1j7&sourceid=chrome&ie=UTF-8
Maybe things have changed in Android 9 or 10, but please test it out if you haven't already!
EDIT:
It looks like you tested it out in another XDA thread already where others lost wifi calling when it was disabled, but you said you were still able to make wifi calls. It's strange that you're the only one who can disable My Verizon Services and make wifi calls, but others can't. Very strange.

My wife has a Verizon device Pixel 3 locked bl and I have a Pixel 4 and they both have MVS disabled and both can call on wifi. I just tested again to make sure. Really, I'm the only one? Gotta love that. I hate that they can get into my device without my knowing and see what and when I installed stuff.
