I updated my 1520 to 8.1 and having 3 very anoying problems, does some else also have these problems?

1. random reboots, dunno what is causing them, started suddenly 2 days ago (did not install any new apps)

2. no sound/instructions when using Here Drive+ (normal sound is working, only no sound in Drive+)

3. When picture tile is set to show favorites it does this only for a short time, then the picture tile goes blank (show theme color) and does not show any photo's anymore. Only when i go into settings and choose other pictures (and back to favorite again) it shoes photo's again for a shiort time.

4. random battery performance. Somedays the batt performance is poor (batt empty within 12hours) and other days the batt is great (still at 70% after 12hours). Have no idea why it is sometimes bad othertimes great, use the phone on these occasions the same.

If you've installed WP 8.1 less than a week ago, issues are to be expected, especially with the nature of the update (OS, but NO firmware). If you haven't already, soft reset your phone & see if that helps.

Check Battery Sense for what's abnormally draining your battery. Re-install HERE Drive +... and I got nothing else.

Remove and reinsert the SIM, that fixed my reboot problems but that was back on 8.0.

Also, ensure you have installed that very latest 8.1 update update. The one that came out afterwards gives me legitimate 24 hours battery life. Much more if I'm not on it all day.

Soft reset.

Get in the menus for Here Drive to see if something is amiss. Also ensure that media sound is up.

Good luck!

I have the reboot problem too but I'll try the SIM card tip.

reset your phone if you have time, this is proven to be very uselful for many ppl including myself. I'm at 91% after 11 hours of usage (almost no usage,standby).

Agreed - did that with GDR3 and the 8.1 Preview. With both, battery performance had deteriorated after the updates, but were much better after the reset.

Yup. My 822 was working ok before I reset it but works much better now. Between the 8.1 update and the hard reset everything improved.

classic event of bad installation. The only way to fix it is to wipe it and do again.

1. No reboots whatsoever on my 810 that's running 8.1.
2. Doesn't apply to me because I don't use Here Drive+.
3. I've never experienced that tile issue you described. Sounds really odd.
4. The battery on my 810 seems okay, but not as good as it was back when I was using the phone regularly on Windows Phone 8.

Maybe a hard reset of your 1520 would correct all your issues? Couldn't hurt to try.

I noticed you thanked my post, but did the SIM removal/reinsert help?
