Hi there. I bought my G3 D855 Vodafone 16GB 2GB RAM about 1 year now (cause i bought it to take picture and record my baby when he was born,lol).
Ok, first my phone is not a new one (like new 99,99%) and its working very good until now except 1 thing, ya thats it ==> AUTO RESTART OR SHUTDOWN.
When I bought it, it was on Lollipop already, stock ROM (not remember the build version). But after 2 months using, its starting got this problem. Sometimes, i need pulg in the charger, few times need take out the battery.
After 6 months, I decided to root it and flash Bliss Rom (u can find it in the G3 forum here). After few days, the problem came back.
Now, after I read many topic and try to do 2 things:
- Change battery (because, sometimes yes just sometimes I noticed before my phone shutting down it not sudden shutdown without warning, it showed a message somthing like: "Battery..............", it want to say the battery is not right or something, Im not sure and remeber exactly). But its only very few times. I dont know anyone there have the same as me. And with this I can press Power button to turn it on.
I bought a Polarcell 3100 mAh from Germany shop via Ebay. Just changed into it today, not yet have shutdown problem or auto restart, still following.
- Force my phone under 2G signal. As myself, the problem showed up when I turn on 3G, got a call, took a picture, use GPS, most times with me it will happen. And when I'm on a call and turn on the speaker, it will happen too. Still following and will update to you guys/
Anyway sorry for my bad English. I think it is hardware issue and pity for who like me, didnt under any warranty we just try to find out a way to keep this problem as minor as possible, right?
P/S; my serial number starting with 410 too, due to a guys from few pages before notice that from 410 serial number phone working flawlessly, sorry its not!!!
