I've only rebooted it once or twice since I got it (a little over a week ago)...but I think that was just when I was trying to set it up. I'll have to wait a few more weeks to see, but as of now, it doesn't look like I'll have to reboot it very often.
Two to three times a day, mostly the browser hanging up or android player not starting. I don't really haven't specifics, I just know it is getting aggravating. My 9800 same thing.
if i use mine, especially the browser, for more than a couple hours a day it will need a reboot to get enough memory back so i can use the browser with more than 3 tabs and another program running. its borderline as bad as the old handset days and daily reboots
Got to the point where i had to re boot every week, I never rooted it or abused it so not sure why it played up. I gave up 8 days ago and bought a galaxy tab 7.7 and although pricey its beautiful, and feels expensive, well made hardware. Not a fanboy just a geek who loves his tech.
I've had to do a couple of reboots. although my problems seem to be more wi-fi related. Now I'm simply restarting my wi-fi sessions, and that seems to be doing the trick [too soon to tell for sure...].
I just rebooted mine last week and the last time it was booted was about two weeks ago. I avoid Android apps as I noticed in the Betas that Android apps or the player took lots of memory.
I had issues when I had Kindle. Since deletion, everything is back to normal.I restart for good hygiene a couple of times a week, before I put it on the charger. Android apps are a killer for the PlayBook.
Some days I need to reboot five times, other times I can go a week or two without rebooting. Sometimes I get over 600MB free... Other times I have 300MB and I need to restart. Haven't quite figured out a pattern yet for the memory leakage, whether it is flash, android, crashes or hangs or what. When it works well I love my Playbook but when it loses memory I hate it.
Must say iOS 5.1 is bad. Never had to reboot my wife's iPhone4S until I got 5.1, now have to restart it often as it loses its network connections both the wifi and 3g. Other bugs too so even Apple isn't perfect.
I've had to reboot after long periods of standby or when an app does something unexpected. Most recently, the native Facebook app. I tried to upload a video and an unexpected error occurred which said to restart Facebook. That's when things started hanging up. I could open my settings menu, but I couldnt scroll, couldnt open keyboard, couldn't click on power icon to restart... had to do hard reboot.
Actually, even after rebooting, FB app still had the same error so I gave up lastnight. I'll probably delete and reinstall later.
