Tablet boots automatically when connected to charger - Android Q&A, Help & Troubleshooting

I recently flashed a custom rom for Lollipop(aosp-5.1.1-p5-20150513) on my Galaxy Tab 8.9
Everything works well but there is one annoying issue:-
When I connect the tablet to a charger it automatically boots up.
Is there any way to prevent this?

[Q] G tab suddenly stopped working

hey,,
My G tab suddenly stopped working yesterday. It wouldn't turn on, however, the charging indicator gets lit when connected.
It suddenly crashed and shut down while I was browsing. When I tried to boot it, it would just keep displaying the vegan logo on the startup. I tried to turn it off and on back again but it wouldn't turn on again.
I should note that the last thing I was doing was installing Skyfire browser and Inbrowser, the latter from Amazon appstore. Which is the browser I was using.
The tablet had about 5-10% battery left (I wanted to link it but unfortunately I cant). It has been connected to the charger but it seems it wouldn't boot nor the battery indicator to turn green. (Edit: It seems after almost 9 hours the indicator is green now)
Also, about an hour before the incident, I was able to reboot it successfully.
Does anyone know why this is happening? And how can I solve it?
Thanks in advance

[Solved] S4 with Netgear Push2TV PTV3000

I had quite the time getting my Netgear Push2tv adapter working and thought I might share what I learned in case anyone else has issues with theirs. My adapter out of the box was on version 1.0.13 and did not work! The S4 would see it but when I would connect it did nothing but continue to connect until I stopped it. I flashed firmware after firmware to the adapter and power cycled the adapter, my tv, and my phone until it finally worked!! Here is what I did, step by step, in detail, to get it working. (trimmed a bit )
First you must upgrade your Netgear Push2tv to the latest firmware. Here is a link to the official firmware and instructions on how to upgrade.
http://support.netgear.com/product/PTV3000
1) Download the latest firmware version (v2.2.16 as I'm writing this)
2) Unzip it and grab the PTV3000_V2.2.16.sbin file.
3) Hold the side button on you netgear adapter for 7 seconds, it will go to upgrade mode.
4) On your pc go to your wireless connections and connect to the push2tv adapter.
5) On your pc open a browser and type http://192.168.3.1 in the url bar.
6) Upload the unzipped file from step 2, and update it.
I am not sure if the following is needed or not but this worked for me after hours of trial and error
7) After the adapter's firmware was updated and rebooted(automatically), I turned the tv off and on again.
8) I was a few updates back on the rom I was running (hyperdrive v5.7, verizon) so I did a complete wipe and flashed the newest version (v7) with the stock kernel. Once settled into the new rom everything was good to go!!! A full wipe and rom flash may not be needed but that's what I did.
I do know that right after you update the firmware on the adapter you will have to reboot your phone at the very least as it seems to hold the old connection to the netgear adapter. If rebooting your phone doesn't work try rebooting to recovery and wiping cache and dalvik cache. If that doesn't work then try suggest a full data wipe.
I have been through multiple firmwares for the adapter, was getting audio but no video, connect then disconnect, not connecting at all, black screens, hdcp errors you name it. After doing exactly what I stated it is now working and mirroring the screen rather well. There is an acceptable minimal lag time between touches on the phone to the mirroring screen. Any type of action/shooter/racing/ game won't perform well but puzzle or rpg games, videos, web browsing are pretty nice !!!
screen mirroring has been disabled - how smart is the PTV3000?
Hello
I have just bought this gadget and the first thing I did was update the firmware to v2.2.16, the phones see's the PTV and connects but after a short while I get the message "screen mirroring has been disabled" and the phone turns screen mirroring off.
My phone is a GS4 i9505 and I have tried multiple rom's and get the same message everytime, so I have to conclude that its not the phone or what ever ROM I happen to be running.
The first test I did was to the PTV3000 without it being connected to a TV/Display - I get the same message about Screen mirroring being disabled.
The second test I did was on a spare commputer monitor with a DVI port, so used a dvi--to-hdmi adapter. But Im not seeing anything being displayed on the screen, but ive seen this before with this screen as I dont think it supports hdmi properly.
Is the PTV3000 smart enough that if it can't display it will disconnect from the phone..? if that is the case why is the phone disabling screen mirroring rather than just saying it cant display of what ever..?
thanks

Samsung Galaxy S3 Bootloop

So I rooted my International Galaxy S3 GT-I9300 about 8 months ago with CWM and started running CM 13 on it. Went smooth till about a few days ago, when I was taking some pictures using CamScanner and my phone just turns off. No message, nothing. Just goes blank instantly. Since then, it's stuck in a bootloop whenever I turn it on. I can get into both download mode and recovery currently. No nandroid backup (Extremely stupid of me, I know). And for some reason, my PC doesn't recognize my phone both in recovery and in Odin/Download mode. Thinking that it might be a bug in the ROM, I did a factory reset and flashed CM14.
PS : Couple of bits of info, dunno whether relevant, but anyway :
1. Very weak battery - Percentage fluctuates wildly.
2. I've been running Xposed for quite a while now, however, I had just installed Greenify and set most apps to force hibernate.
3. I've already wiped the cache and Dalvik cache.
4. I already had the drivers installed on my PC; I regularly used to connect my phone to it.
5.I had USB Debugging enabled when the phone went off.
6. A couple of times after the phone went off, I was able to switch it on if the charger was connected, but switched off immediately when I disconnected the charger; it was like a pc going off when you cut off the power supply - no message, nothing at all - just went blank.
7. Dunno why, but my phone refuses to charge unless I use a particular cable and hold it at a particular angle.
I've been trying to find a solution for this for the last one week, but this seems to be a unique case. Please help!
Issue resolved. Turns out, it was a battery issue
