(e.g. 51.14.15) have a bug which cause the formatting of phone filesystem as soon as free memory falls under around 4-5 MB; user is not asked for confirmation, so any data in the phone memory is lost in this case. Further firmware releases fixed the problem (maybe starting from 51.92 Outbox bug - If an SMS sending fails, SMS get stuck in the outbox and no more attempts are made by the System to send it again. No fixes are available for this bug. Memory card size limitation - Although a1000 is compatible with microsd, which should allow size up to 2 GB, no users report to be able to go over 1 GB limit AT commands incompatibility - most of standard mandatory AT commands are actually not supported, implemented or working (SMS access, phonebook access,...) Reported hardware issues Charge connector - charge connector does not always connect to the phone, so it does not charge properly. Limitations Memory card lock - Early releases of firmware do not allow installing applications to memory card, and stops memory cards from going over 1 GB, but "NOPEX" 3rd party application fixes this issue. Missing autoconnection - Unlike other UIQ phones, a1000 is not able to auto-connect to PC when USB cable is connected: user intervention is required to tap the screen to activate connection; this makes it impossible to recover data from phone in case of screen damages/crash.
