HTC EVO 4G :: Phone Randomly Disconnecting From Usb Port While Plugged In
Aug 16, 2010
I got my Evo today, finally. I noticed when I plug in the usb cord to my computer, no matter what I set it at (charge only, mount hard drive, etc....) the computer makes the noise like i've unplugged something from the usb even though everythings still plugged in. once it does that the phone is no longer charging and I cant see the hard drive anymore until I unplug and replug it back in. then it does it again within a minute or two.

We have an S3 Mega, started using it as a Wi Fi access point for a Gateway Desktop, Windows 7. After 8 hours of flawless operation , the usb starting disconnecting and then reconnecting.The check box in the settings screen for USB tethering would uncheck. If you rechecked it it would connect then disconnect and uncheck the box. We moved from a front USB port on the Gateway to a rear USB port and that fixed that problem but after overnight, no WiFi access. Rebooting the computer fixed that.

When i'm connected to my router at home via wifi, the connection randomly drops from time to time. My laptop and TV is fine which are both running via the internet. The setting is set to stay connected always, even when the screen goes black.
Does anyone have a resolution for this? Perhaps static IP? if this is the answer, what should the settings be?

I'm thinking about an Android app (with possibly an accompanying physical device), and i'm trying to figure out whether this is something that's feasible.
1) Let's say I plug my Android to my PC. Would it be possible for an app installed on the PC to communicate with an app running in the cell phone? I just need a very simplistic data exchange, it can even be one-way (just data pushed from the cell phone to the listening app on the PC, whenever the cell phone wants, I don't need any data sent from PC to phone).
When I plug it in, the phone gives me 4 options (charge, disk drive, HTC sync, tethering), which makes me think this is not doable, but still worth the shot.
2) Would it be possible for an app on the PC to talk to an app on the phone through any other way? (Wi-fi, bluetooth, etc). I'm guessing no on wi-fi since neither party has the other's IP (and I want this to kinda just work, not having to input IPs manually all the time).
3) If I make a device that's plugged to the little USB port at the bottom of the phone (and let's say this is a magical device that can do anything, I don't quite care about those details as long as it's doable). Can I have an Android app talk to that device?
4) Any other ideas to make the phone talk to a "device" that I make, or to an app in the PC are more than welcome. Going "through the web" could be an option (although there'd have to be a central server that I own as a middle man, I believe). But i'd prefer if the communication was direct between the two devices.

I was trying to update boot image, and no dice. Everything was nandroided and I re updated 0.7 BB 2.1 for cleanliness. Everything is peachy when on battery, not on USB. EVEN after cleaning cache and all that, reboot loop. I didn't nandroid this issue, I know that.

I'm having a really strange problem when listening to Pandora or Last.fm radio on my Eris (haven't tried music off my SD card yet, still have it all on my old phone) through the aux port on my Sony headunit.
When it plays, sometimes it will skip to the next song at random and even make a PHONE CALL to the last number on my call list! All while the screen is locked. Yes, the phone will unlock, make a call, and skip songs without me touching it. I was thinking it's the cable (cheap-o I got from dealextreme.com) but my friend's Motorola Droid works fine in my car. I jiggled the cable around where it was plugged into the phone and it skipped a song. So I tried plugging it into the desktop HD radio's aux port at work, and it works fine. Jiggling the cord did nothing. So could it be the cord? Or is it my headunit? The thing is, my LG Chocolate2 worked just fine in my car (with an adapter plug) with the same cable/radio.

I am struggling to connect to my home wifi network. I very occasionally can connect but there seems to be no obvious method to the madness just some black magic. Basically it sees my network it has remembered the key, the key is correct, and it says disconnected. I press connect and nothing happens at all but sometimes it will say "connecting..." then it will immediately say disconnected. I have a belkin router and my network is secured using WPA/WPA2 TKIP/AES encryption. I have tried using APNDroid to turn off my mobile internet before using wifi and that sometimes works but that seems to be more black magic than a solution.

Well after almost one month of frustration with this phone disconnecting my call while talking.because of the screen touching my face. I finally have a solution Hurray.simple when call arrives hit the power button Once. the screen will go black and lock. and you can move all over the screen with touching etc and the call continues when you are ending the call just hit the power button again and everything goes live again on the screen to conclude the call. I was to almost ready to go back to my old phone just to be able to talk on the PHONE.

I've only just noticed an issue that after disconnecting from wifi my phone doesn't automatically go back to 3G/2G.
I have to turn the wifi back on and when it can't find one only then does it decide to connect to 3G/2G.
Didn't have this issue before and I'm thinking the latest update (1.31.405.5) has something to do with it.
Anybody else having similar issues?
BTW I'm on the vodafone UK network.

Is it bad to use your phone while plugged in (web browsing, music, tv)? I know it will take longer to charge, but is it bad for the battery or phone? Also, anyone else notice that it takes longer to charge after 2.2?

Does it hurt the phone or battery any to leave the phone plugged in while fully charged and using it? I have been watching a lot of Netflix lately and have been leaving it plugged in when watching even when it is fully charged.

I was able to root my phone with this method when everything else failed. Try this if you have had trouble with other methods. I did not discover this, I heard it from someone on IRC (forgot who).
1. With your phone booted up and plugged in via USB, type adb reboot recovery.
2. Start your adb shell loop (using the while loop or bat file).
3. Click in and out your SD card repeatedly while the phone is booting into recovery (apparently every 0.5 sec will do).
4. Watch for "- exec '/system/bin/sh' failed: No such file or directory (2) -" to appear in your terminal
5. Follow the rest of the instructions at public:adb_in_recovery [RootWiki]

I've heard that today's batteries' health depends on how many cycles they have gone through, and considering this it should be wise to leave the phone plugged in while fully charged and under heavy use. This way you will delay the cycle and get a "healthier" battery. This was just MY theory and I was not too sure about it. Please correct me if I am wrong.

I've made a nice little dock while I'm at work for keeping my phone upright and flat against a board while plugged in at my desk. This enables me to answer texts by just reaching over and tapping out my reply instead of taking the phone into my hand. What I'm after is an option, app, widget, Anything that will allow my phone to stay on while it's plugged in (sort of like a mini laptop). Right now it goes black after a minute, as it would do if it was on battery.
The only option I can find in the settings is when to turn off the display, which only offers a maximum of 30 minutes and doesn't take into consideration whether you're on battery or charging. It would be preferable if this option existed only while on charge, as I don't want my phone on all the time while on battery, obviously. For what it's worth, my Desire is running 2.2 with the Cyanogenmod 6.0.2 ROM.

I own an EVO - when I connect it to my Dell Vostro laptop it charges without any problems whatsoever. When I attempt to charge it from my work laptop (Dell Latitude) it never charges. I am not changing any settings, just simply unplugging it from the Vostro and then plugging it into the Latitude.

My phones got a full battery but if I go to take it off the charger it shuts off. I've tried taking the battery out but still doesn't turn back on unless I plug it back into the charge. I need my phone for work I drive the work truck and have to stay in contact with the people at work.

What I'm trying to do is write an app on my Nexus S that does something when the phone has been plugged in to a USB port. Is there such an "on plug-in" event?

My droid has been plugged in all night, today i had to take a trip to city, so I unplugged my droid and plugged it back into the cig lighter (verizon plug, not after market) and started up Trappist. Battery was full when I started, when I got to my destination an hour later the battery was at 50%. Why is it discharging if its plugged in?

Is there a way to set different behaviors based on whether the phone is plugged in? For example, I want my screen to stay on when I have it plugged in in my car. Is that possible?

I just got my update notice, but don't have 40% batter power. Can I run the update with the phone plugged in? Otherwise, I'll just charge and wait until morning.

ok this is what is wrong with the phone. about 2 days ago my phone acted weird it shut off but after a while it came back on. Then yesterday it did the same thing but it never came back on. the phone was fully charged and as i went to reach for my phone to wake it up it didnt do anything. I have tried the power and volume for 2 mins nothing. I have had it on the charger but all it does it is hot but no light. I have never rooted this phone and dont know what is wrong with it. I only had this phone for 1yr and 3 months. All my contacts, recipies, photos, ect are on it i even tried to see if i can contact it to the manager nothing.

how to stop the phone from beeping when plugged.
I upgraded my Samsung S I9000 from stock ROM Gingerbread to Cyanogen 10 (Android ICS).
The phone used to beep when plugged and now it does not anymore. Having I sight issues that audio clue was useful.
I cannot find how to enable it back.

I have a Droid X and so does my GF. Both of us have obviously been adding apps, trying to figure things out, etc. quite a bit. She plugged hers in last night to charge and it turned off. We thought maybe because it was so warm from messing with it. Well, today it's turned off twice for no reason at all. Anyone else have this problem or have a recommendation? Everything seems ok on hers when we compare our two. Mine has yet to do this once?

Got this phone yesterday and was all good. Let the battery run out and plugged it into charger overnite. Didn't charge.Tried the usb into the pc and got the battery with the lightning bolt symbol. Plugged into wall outlet wont work. What gives? I tried taking out the battery for 5-10 mins and still nothing. The guy at support asked if I could turn the usb the other way like I was an idiot, and I explained to him that it only goes in one way. Any ideas? I plan on taking it back if I cant solve it.

When at work I usually have mine plugged into my laptop to charge it up and today I notice that it's getting warm at the back. It's not even been used at all for the last 2 or 3 hours, it's just been sitting there on charge.

Running my finger along the side of the case I noticed a weird sensation that at first I though was the finish on the casing, but it registered as more than that, so I unplugged it and it went away. Have since discovered that the sensation is only present when plugged in, but NOT charging - i.e. power light is green.
