Hi,
I've searched but can't find anything, hopefully I didn't miss anything.
I'm using the Zenithink ZT-280 C71 with official firmware 2.3.4. Since it doesn't have built in bluetooth, I'm using a Bluetooth dongle. It works fine except it seems to have a problem with the power saving function. After some earlier confusing results, I found that if I let the tablet sleep (whether after time or if I push the power button), the dongle light goes off. When I wakeup the tablet, the bluetooh dongle LED comes back on but Bluetooth no longer works. If I try to enable Bluetooth, it tries very briefly then gives up. If the Bluetooth is still working, I can enable or disable it and reenable and it's fine although I'm not sure how much it does. This doesn't happen if the tablet is plugged in, it's working fine hours later. So I'm pretty sure it's because the tablet disables USB power which unfortunately breaks the dongle requiring a restart to fix.
Is there any way to disable USB host mode power saving? Isn't good from a power saving perspective but then needing to restart I've looked in power control widget but nothing useful there, some setting in the build.prop perhaps? I've fooled around with hacking my LG Optimus P500 and another phone before so no problem changing files etc.
Alternatively I could try making the USB bluetooh dongle work with powersaving (although possibly this will be more device specific). I'm not sure but possibly the problem is related to the fact hotplugging doesn't work. If I start the tablet without the dongle and later plug it in, I similarly can't enable Bluetooth.
Any help much appreciated.
My touchscreen just crapped out on me a couple weeks back. I've bought a new phone and was able to retrieve all my documents/pictures from my One XL as it functions perfectly in all other aspects other than the touchscreen.
I was hoping to turn this into just a not so portable PMP having it permanently sit in the dock so I can watch movies and youtube while on my PC and control the phone via the usb port with my mouse. I tried my OTG cable with a usb mouse but that doesn't seem to work.
I also tried android screencast which while it mirrors the device's screen onto the PC doesn't actually grant any control over the device.
I was wondering if you guys knew of a way I can bypass my lockscreen via using the ADB as that's the first hurdle I need to get through.
Hi,
Z5 suddenly decided to stop working.
Phone is PIN + Fingerprint Locked, Touchscreen is not working at all.
Here is what I have tried so far,
1. Attached a USB OTG Mouse, was not able to detect
2. Tried Multiple Reboots, even using the small yellow button besides the sim slot, but fingerprint unlock is not working as PIN is required on reboot, which I can't enter
3. Booted in Safe Mode using volume down key during boot, but still screen wont detect touch
4. Connected to PC, asks to unlock the phone, but cant as touch is dead
5. Removed screen guard
Phone is stock android (No rooting, nothing), has a memory card, removed the 2 SIM's
Phone is not dropped, not wet, not cracked
********
Solution Found & Worked
Switch off the phone, plug a USB OTG & Mouse Receiver, turn on the phone, you'll see a mouse pointer, that should get you somewhere.
Was able to unlock my phone, remove the passcode, will copy the data once I have it fully charged.
Great post - Thank you so much
after dropping my phone a few times, didn't realize its any longer waterproof, seawater damaged the screen and I'm unable to unlock it, it requires me to execute my pattern password to unlock it. I need to reset the phone to erase my data and sell it. Good thing I have an OTG somewhere to use. Thank you so much again!
works for me. i almost get frustrated with this phone. i lost hope in using otg since everytime i plug one i need to accept it in usb connectivity. i didnt know you can force it by booting the phone with the otg and mouse or keyboard already in it
Hi,
I hope this is not a cross-post; I've read a few other guides and suggestions on this forum already but my problem seems to be the opposite of what many people have.
I've got an Xperia Z5 Compact (not rooted) with a chipped screen. Touch does not work at all, but the display works fine.
I plugged in a mouse via OTG adapter and enabled USB debugging, then plugged it into my PC to attempt connecting with ADB. However, once I plug in a new device the phone wants me to confirm to "allow" the connection coming from my PC. But since my mouse is no longer plugged in, I can't accept the popup.
I tried to connect with AirDroid as well to try to accept the popup via screen share, but in order to allow WiFi screen sharing, it needs root (or an adb connection).....which makes the problem kind of circular.
Any suggestions or tips (or resources I might have overlooked?)
Thanks,
Rafael
Hello there, so i broke my screen on my OP5 and waiting for a replacement one right now but meanwhile - My PC doesn't have a connection since i am always using my phone USB tethered when i am on my PC.
I can turn on normal hotpot with the assistant etc but i can't do USB. Anyway i could workaround this?
