Android :: Android Screen Lock - Car Charger
Sep 11, 2010
I have an app which I can put into airplane mode remotely to save power. I have a thread running which gets the power-save message, removes callbacks for all other threads, puts the phone into airplane mode, and waits a specified number of minutes before waking the phone back up.
When the phone is plugged into my laptop (USB debugging enabled, etc) then this functionality is fine. The phone goes into airplane mode, the screen locks, and then after a specific number of minutes the app "wakes up" and continues as normal.
When the phone is plugged into a car charger, the phone phone goes into airplane mode, but the thread never wakes up the phone. This problem only occurs when the screen is also set to timeout...when I set the screen to "never timeout" and have the phone plugged into a car charger, the app wakes up just fine.
It appears that some combination of power source and the screen timing out kills my power-save thread at a system level. I know this post is very specific to my application, but has anyone encountered a problem similar to this before?

Is there anyway to disable the initial swipe lock screen and replace with the pattern lock? Seems silly to have a double lock.....the pattern seems much better to me.

I am plan B and AVG security installed, both don't always work, I have pattern lock on the phone but even in pattern lock mode when i press and hold power button the phone gives me option to shutdown.
If someone steals my phone they will be able to shut it off without unlocking it since holding down power button still works. So is there a way to lock the power button from shutting off phone when the phone is in pattern unlock mode?

I have an HTC Evo that hangs up on everyone that calls me.I keep the phone in my pocket and, in trying to pull it out to answer a call, my leg slides the bar.I could keep the phone in my pocket upside down and then I would answer every call but that isn't much of an alternative.I am looking for something that overrides the Sense's lockscreen/answer screen.I tried both GoTo and WidgetLocker.Both are great programs but neither addresses the incoming call issue.

Is there a way to have a phone lock on the Desire, in the way it is used on "normal" phones? What I mean is that I need a phone lock for security reasons - however it is a pain to use it every time I turn the screen on. Is there a way to have it work only when you turn the phone on? Right now if yu don't have a phone/screen lock security set if someone steals your phone they take out the sim card and use the phone normally ... if you do have it, then you must use the password every time you want to use the phone (I hate it). I know the best thing is to have a secured access but I was just wandering if it was possible to do seomething different?

I have a third-party micro-USB charger that I bought in an airport once for my Tour. When I plug it into my EVO, the screen becomes unresponsive. I'm not using the charger for now. Is this charger potentially causing damage to my phone?

I bought a 3 charger bundle at eBay for cheap. When I tried using the wall charger, the touch screen freezes, and I can't do anything with the phone, while charging. Do you think it's safe to continue using the chargers I bought at eBay?

I ordered a combo kit from amazon, very cheap. I know some chargers lock up the screen, but this one had a review from someone with an Inc. saying it was fine. Anyway, wall charger locks screen, but shows it is charging, led lights up. Car charger works fine, no screen locking up.
So... am I doing any damage to my phone using wall one? Was thinking I would just use overnight when phone is off. Anyone else using one that locks phone?
I can always just toos wall one, and keep the car one, still great deal for the $4 is spent.

When I plug my phone into the charger the screen comes on and never turns off. Is this happening to anyone else ? It isn't a huge deal because it is on the charger but kind of annoying.

I've had my Evo for less than a week. When I bought it, the Sprint guy gave me an extra wall charger that he had lying around. I used it a couple of times and a few days ago, the screen started freaking out without me even touching it, selecting things toward the bottom of the screen. Most notably, if this happened from the home screen, it would select "Phone" and call whoever was at the top of the list. NOT COOL, let me tell you. This would happen mostly when on that charger, but occasionally even when not, usually when I unlock it for the first time in a while. After a few seconds, it stops and goes back to normal.
Anyway, so I did some research and I think this was caused by the extra charger, which turned out to be a Kyocera one. I've stopped using it, hoping that would fix the problem. But it happened again today and I'm sort of worried. I want to know if this is doomed to keep happening or this will go away eventually.

Will virtually any mini-USB based cable, car charger, and wall charger work with my HTC Droid Eris? Mini-USB cables are generally universal, but I want to ensure that I use a compatible car charger and wall charger that won't damage my phone. The official Verizon accessories of course seem overpriced, if any generic solution would work equally well.
For example, I am considering this product on amazon.com: Amazon.com: Home Travel Wall Charger + Rapid Cell Phone Car Charger + USB Data Sync Charge Cable for HTC Touch Pro 2 / Tilt 2 / Hero / Imagio / Pure / Touch Diamond 2 / Droid Eris: Cell Phones & Service. Overall, this mini-USB cable / car charger / wall charger combo gets positive reviews, but I've heard of random glitches for some cheap chargers.

The house charger that came with my phone in the box works perfect. I plug it in and the phone shows charging and then the screen goes out after the 30 seconds I have it set for while its charging.
I bought a Rocketfish charger from BB to have an extra one I can leave downstairs. When I charge the phone with it, after about 5 minutes the screen lights up on my phone and stays lit until I unplug the charger. Then the phone will go back out like it should.
I though there might be a difference so my nephew gave me his home charger he dont need. Its the charger sprint sent him by mistake for his phone. He has the Blackberry and they sent him the micro-usb wall charger. He gave it to me and when I plug my phone in with that charger the screen lights up and never goes out until I unplug the charger. I dont want to mess up the phone and was just wondering if there is still a difference with the chargers even though they are all micro-usb chargers?

Does anyone else's touch screen become unresponsive when the Epic is being charged? My touch screen gets glitchy and only responds to a fraction of touches.
I just received mine yesterday and I've already spent more than 6 hours trying to troubleshoot this issue. Most of the google searches that I've found have to do with cheap 3rd party chargers, but I'm using the OEM Samsung charger.
I thought it might be the charger, so I went out and purchased 4 different chargers today, but none of them fix the issue.
I also ordered another Epic for my wife at the same time, and her Epic has the same problem, which suggests that it's not a defective phone (unless they both came from the same batch).
To confuse things even more, I've been able to isolate 2-3 outlets in the house where this problem doesn't happen. The problem also doesn't happen when I charge at work, through a car charger, or via USB from the laptop.
I'm inclined to think it has something to do with the outlets in the house. However, I've never heard of any issue like that and the house is relatively new (built in '98).

Anyone else have screen issues with a different brand charger? I use a blackberry at work and it seems when I use that one, it is the only time I lose all screen functionality. It starts going haywire. If I touch the A key, it will select the N or something completely off the wall. If I unplug it, wait about 60 seconds, it works again. Wonder if anyone else has an issue with other brand chargers? Going to toss this one but thought I'd let people know in case they run into the same issue.

i donīt know if this is the right place to report bugs, but there it goes:
Android: 1.5 Phone: Samsung Galaxy Firmware: Any
I found an annoying bug when the screen stops locking, and the workaround is to restart the phone or restart the dialer application. This bug happens when you use a SIM card that changes the dialed number (there are SIM cards that inserts a operator code automatically in the number) Steps to reproduce the bug:
- Activate "Auto insert operator code" feature in your SIM card (usually in "SIM Toolkit") - Make a distance call (without the operator code) - It will show a dialog in screen saying "Number changed by SIM card" or something similar - You donīt have to complete the call. From this point, if you try to lock the screen, it just turns off the LCD, but the screen is not locked (if i press any button the phone goes on, unlocked)

I am using the OEM charger on my Dinc and nothing else. I randomly get a message something like, "The charger you are using is not compatible with your device. Remove the charger now to avoid damage to your phone". I have not used anything other than the OEM charger ever. It isn't loose or frayed or bent strangely. It also seems to charge even though the message pops up. For now, I'm using my computer's USB port to charge it but man, that's SLOOOOOOOOW. It has done it since I first got the phone and before I had even installed my first app. It also does it after a factory reset and reprogram. Customer service is sending an aftermarket wall charger free of charge until I can get an OEM unit as they are obviously out of stock.

I'm building a custom Home app. I want to change the lock screen to match my theme. For example changing the wallpaper. What I see in the lock screen now is the default wallpaper. I've tried searching this forum but can't find the solution. Yet I found some apps on the market that can do this.
