Hi,
I bought a850 2014 may. It started giving battery problem after 3 months. As it was in warranty period i was able to repair. But the service was horrible. after service when I connected to the server, it started acting horrible. In charge when I touched @ any apps it open some other apps, or try to uninstall a app or try to make a call etc etc. @ than point i used to switch off the cell and charge. after service usb was not detecting. Then after a month I was not able to charge again, I have to give some support in the charger to charge the phone. I changed 2 usb charger for that. then after few months it started giving mic problem. Now kept the phone to show any people who is planing to buy a lenovo product so that after seeing my phone then won't go with lenovo. It a horrible phone. Camera quality is worse than chines phone(which came in 2007-2010). Can not upgrade. Lenovo service is so poor. You can say A850 is a hanging phone. It always say "I am not responding"(any app). Battery quality decrease frequently. Network issue.
But its WiFi is faster than galaxy note 2.

Hi, please try to hard reset again, then after your phone start again from beginning please do not login with previous Google account, you may try to create new Google account.

However, if still can not work although you have done what we write before, then please consult with Lenovo authorize service center.
Sir,I just bought the Lenovo A850+(the screen is 6 inches right?) a couple of months ago.It was working pretty fine until the phone said that the USB storage is broken.It told me to reformat the SD card I had already reformat it.When I switch on the phone,there was a lot of pop up keep popping up and when I say a lot,I meant REALLY a lot.I can't even open any apps then I decided to remove the battery.I am charging it right now.Please help me I'm desperate to use the phone.Thanks.
Hi, the pop-up information will keep any notification. But it also can be trouble with applications like viruses or malware, because the conditions is similar with your trouble. However, if you also thing this is SDcard trouble, maybe you can try to remove your Lenovo A850 plus microSD external storage and boot again one more time to make sure weather this problems still happen or not. If all possibilities already done but still not fix your trouble, then you have to do hard reset LENOVO A850+ using hardware button combination key.
