Lollipop upgrade was pretty disastrous for my phone. Have had a bunch of issues e.g. never finding 4G, wifi switching off, unit overheating, battery draining even when charging, app updates continually freezing at the same percentage, SMS messages taking an eternity to send, etc, etc, etc.
1. Have pulled battery and cleared cache, with no joy so the next option seems to be factory reset. I "think" everything including apps has been backed up on my google account. Can I can check that on my laptop?
I had definitely backed up on Kies before I did the update and since then. However a new problem problem is that Kies doesn't recognise my phone when I plug it into my laptop. It connects to the computer as a media device and the phone name appears in the hardware connected to the laptop but in Kies it just spins round, sometimes offers me a camera upload. Have tried various cables and re-installing drivers but no joy and I do have the MTP check box ticked
2. I have spent a week trying other fixes and mainly keeping the phone in Ultra Power saving mode where it worked ok as phone and SMS machine, charging properly, etc. If I factory reset my phone now, I am concerned it will still not connect to Kies and I wont be able to restore it. Has anyone else had this problem? Did the restore go ok?
3. Wondering if I can actually go back to the last 4.4 backup file rather than the more recent 5.0 that I have although the consensus seems to be that the factory reset gets Lollipop running very smoothly. Any advice on that?
Apologies for length of questions. All help appreciated. Cheers.
