Hi, Z3+ doesn't boot after: 1) I switched to Ultra Stamina mode (I never used this mode before) 2) after that I fount that battery drained. 3) From that time the phone cannot boot - red led is blinking while charging. Sony Companion doesn't help - nothing happes after connecting device to USB with volume down button (power + volume up tried). Maybe it's worth to change battery - insert charged one. I opened back cover already - I replaced battery to new one a couple monthes before abovementioned accident. I believe that battery is drained but capable to be charged - but how to charge it directly? Disconnection of battery contact leads to tripple blinking while charging. Also I have additional brain new battery. Now I'm in trip outside USA and there is no Sony service here. Thanks.

I use Xperia Tablet Z4 + BKB50 for 7 months. Sometimes, after updates, it took several minutes to connect BKB50 to tablet and use it for typing. I didn't use keyboard more then month. I updated tablet to Android 6.0.1. Build number 32.2.A.0.253. Now keyboard does't work with Xperia Tablet Z4. After turning on keyboard: white light is on (constantly, whithout blinking). There is entry in Settings -> Bluetooth -> paired devices: BKB50. When I press it tablet is trying to connect for about 30 seconds (string "connecting..." appiars). If I press any keyboard button then "connecting..." immidiatly disappiars. I tryied this a couple douzens of times. So, there is some connection between BKB50 and Xperia Z4 Tablet. But I spent two days trying to type something without success. After last update BKB50 doesn't type and there is no toolbar in the bottom of the screen as it was before. Could xperia team please fix this - I bought this device mainly because it has (had) compatible keyboard. I regret that I have updated device. Thanks in advance.
