After several weeks to months of use of your brand new N82, you might be finding that accessing your memory stick is no longer as fast as it used to be when you just got your phone. If you regularly take photos, transfer videos and music on and off your phone, this is a particularly frustrating issue.

A solution to the issue would be to defragment the external memory of which you store all these files every few weeks to a few months, depending on how often you delete and replace files on the memory stick. Defragmentation sorts the data on the external memory in to a sequential order, thus improving read performance of the external memory as data is now grouped together in chunks.

It's also beneficial to check the external memory for errors to ensure that your memory stick doesn't have any problems or bad clusters/sectors which may cause data on the memory to screw up or go missing / end up corrupted.

This can be done in Windows XP by going to My Computer (after connecting your phone as a USB Mass Storage Device, or by taking the memory stick out and putting it in a card reader), right clicking on the external microSDHC card, going to Properties >> Tools >> Error Checking or Defragment.

Today I had to make a stop at the local Nokia Care center because I had a rather annoying problem. Everytime I clicked on the WLAN shortcut on the N82 standby screen - the one which allows you to switch WLAN on and off - the phone would be stuck in a loop of "System Error" prompts, which would only stop if you pulled the battery out from the phone.

Turns out that this is just one of the few bugs that most users would experience if they updated their N82 firmware to v20.0.062. The Nokia Care representative said that a firmware update to solve this issue is 'in the works', but again who knows when Nokia will release an update?

In this specific case, the Nokia Care rep said the way to avoid the "System Error" prompt was to go to Menu >> Tools >> WLAN Wizard and find the WLAN access point to define it. Tedious but it avoids the "System Error" pop-up, which is extremely annoying.

Any other readers facing issues or problems since updating to v20 for their N82? Feel free to share your experiences and see how others go around the problem.

Nokia N82 users should beware when using the phone for prolonged periods. Some users from this Chinese forum (Sogi!) are experiencing a wide range of issues plaguing the phone; one of them reportedly used it intensively after purchasing it for 2 days (streaming videos, GPS, WLAN) and ended up with the motherboard of the phone screwed up by the heat.

Another user's tale is even more ridiculous - the last time the phone was used intensively, the battery was slightly melted, and the exterior cover charred by the heat of the battery.

I'm not sure if its a batch of batteries that may be the problem, or if it's affecting all the N82's sold since last December.

Surely Nokia should produce an explanation and a recall of batteries for this - judging by the number of features that's provided on board, many users are tempted to play around and do all sorts of things when they're bored.

Do you experience any of these problems / any opinions on this matter? Feel free to comment.
