I bought this C5-03 four months back after did good analysis and read enough reviews. It is very sweet looking comes with handy one. The OS was Symbian and old one. I will share some good/bad for the benefit of new buyers.
Positives:
Good looking one, and smaller to pouch in pockets
Comes with 5 MP camera having good images on daylight, reasonable zoom
Long standing battery and quickly getting charged
Touch screen with 3G voice
Preloaded GPS system, usefule one in city if preloaded the maps
Games response are faster and good one
Cheaper one for the listed feature
Negative/Issues:
Easily slip from hands, not having good grip to hold
It losses signal suddenly, you cant receive or make call, it needs to be switch-off and on to get signal back. My other Nokia phone with same provider has signal. Heard about software issue. This issue applicable for some other feature to.
Touch screen wouldnt work, no response until switch on and off. I got this issue about at least 6 times in 4 months
Alaram feature is not good one, you cant stop it. So repeat until remove the alarm.
Mark unmark featuer is ugly, my previous Nokia phone enable single touch MARK/UNMARK feature once you select the list. It is handy to select messages and remove it quickly. This needs at least three touch for mark or unmark. Express Music has better in this category. I have 5322, it also same issue
GPS system is not meeting my expecation. Also the map is not detailed enough to reach remote area other than cities. I need to data download through service provider which cost me the data txn because of default GPS system is not working most of the time. Nokia must work on this feature. Google map has better map than this map.
Wi-Fi scanning is switching on every next day even I switch-it off from scan.
Sound quality and volume is quite low than my Express Music phone
Data download is not fast enough though strength of signal is high when it works better in other phone.
Major issue, it is hanging suddenly which need to turn-off and on
I never used 3G and other features exclusively, so no comments.
Simply says 5322 is better instrument for cheaper price. It has limited additional feature and good looking one.
This is my 4th Nokia phone, I prefer because of I need not carry phone charger wherever I go. Also most of the Nokia phone works fine even dropped. My Express Music fall on road and hit buy bus tyre, but still I can able to repair it to use it. Most of the features are work as is, even sound quality rather than any drop as in other phones.
Overall, good looking instrument need to resolve number of issues to satisfies the customers.
