It's device dependent, if the manufacturer can fit in the circuitry to use the wall charger without the battery then yes you'd be able to do that. Most laptops can run without batteries, I doubt many smartphone does though; phones are primarily designed to be used while on the go, while laptops are more likely to be plugged in. A safe test is to shutdown ...

From Verizon: Open settings. Select Battery & data manager. Select Data delivery. Select Data enabled to enable / disable.

Does your user manual have any prohibitions about removing the battery while plugged in? That would be my first point of information. And I probably wouldn't try it myself, but that's just me. The issue is that you have no idea of whether the folks who designed the charge circuit accounted for this or not, and you don't know how they did the charging ...

You can use Carbon to backup your applications data. If your devices is rooted you can make a complete nandroid backup using CWM.

Two pieces of ground I want to cover here: /cache is typically a separate partition on your device, which wouldn't be mountable by a PC via USB, which is why that isn't working. The USB connection generally accesses a directory named "sdcard" (or similar) which is used as an external storage device, although this storage area doesn't have to be physically ...

This feature is supported on the Samsung Galaxy Nexus. I routinely change out batteries while the phone is plugged in to the wall charger. The only issue I've noticed is that the battery level doesn't update to the new level right away, but instead slowly increases over time.

I doubt this. I've charged my BIONIC using the following: Griffin technologies Power Jolt Dual car charger - rated 1A Motorola car charger for original Motorola DROID - rated 850 mA Motorola Wall charger for original Motorola DROID - rated 850 mA Motorola wall charger for BIONIC - rated 850 mA In addition, I've used 3 different USB charging cables ...

Does the phone begin discharging at 40%? Does it indicate that it is still charging, but the charge never exceeds 40%? I have had charging issues with my Motorol DROID v1. What I've come to understand is that the power delivered by the car adapter is less than the power drawn by the phone when the GPS is on. I would suspect that a couple of factors might ...

I was hoping the "Wimax" or "Mobile Data 2G/3G" Net Actions would be what you need, but after looking around it doesn't look like Tasker supports 4G on/off switching. Per Tasker forum user Pent regarding this issue (on a different phone): If this isn't currently a feature is there any way to implement it? It isn't and there's no 'official' ...

Just for completeness sake I want to share that I've operated my old LG GT 540 countless times with the battery removed, while the USB cable is plugged in. I can power it up on in these situations (and run CWM). So I guess that there might be more LG Android phones with similar circuitry. Since I've upgraded to my new Galaxy S2, I've been too reluctant to ...

I just tried this on two phones, a Samsung Galaxy 551 and a Samsung Galaxy S. It doesn't work. The phones typically just shut off. However, one time the Galaxy S didn't shut off right away but I wasn't able to put the battery back in before it shut off. My Google Nexus S is made so that you can't even take the back cover off without unplugging it. I suspect ...

Assuming you have rooted your phone, these are the steps that I have had to do in the past to get the OTA to work: Applications BionicBootstrap.apk is custom bootloader used to Save/Restore entire ROM's (backup of my phone) OTA RootKeeper roots and unroots the phone. For OTA: Unfreeze all apps (Stay in Root) Needed to uninstall Bionic Bootstrap Reboot ...

It's a "permission and privacy" thing. While the .apk does not have any privacy concerns involved (and thus can give read permission to everyone), the data do, and thus the directory is only readable by owner, group, and root (not by "other", which is what you would need -- "other" has only eXecute permissions). ls -l / | grep data drwxrwx--x 25 system ...

This problem is quite known for sometime for touchscreen devices. Most of the times this happens when the screen is under some pressure during touchscreen recalibration after being woken up by the incoming call (maybe being inside pocket, etc.). The only solution for you is to disable the option, power button instantly ends call by going into Settings -> ...

Check to see if "System Settings / Developer options / Stay awake" is checked. It's intended to give exactly that behavior ("Screen will never sleep while charging").

No. My friend got an extended battery so I tried my case with his phone -- the extended battery is really large, so it won't work. Which is a shame, because the Otterbox Defender case is so large that a hypothetical extended battery Otterbox Defender wouldn't be significantly bulkier than the current Otterbox Defender (regular battery). If Otterbox made a ...

It seems the issue is network authentication problems caused by Verizon's switch to a UICC SIM-based authentication for both 3G and 4G connections on all of its 4G LTE devices. See this article: http://www.androidpolice.com/2011/12/19/this-is-why-your-verizon-galaxy-nexus-or-other-4g-lte-vzw-phone-is-losing-data-signal/

At least for the Droid Bionic, this appears to be a known software issue. This post on the Motorola support forums includes the following listing. Marginal 4G to 3G transition: Loss of data connectivity - The device may display 3G service indication but no data connections are possible. Action: The user will need to power cycle the device or ...
