I bought the phone 3 months ago. Back then there was no description in a language understandable to me. But I came up with the Manual of Y300 along well, although this is my first smartphone. The Y330 was very quick to set up. That Datenkrake now always listening in, the Y330 obviously can not be blamed. My main application is (besides Tel. / SMS) to use as a navigation device. For this I have been playing in the Navigator MapFactor free version and so far all the targets in D / F / I found that I was looking for. GPS Fix Time outdoors is measured in minutes. The longest time was for 4 minutes on average, the first fix is reached after 2 minutes. This can my Garmin eTrex 20 (= special Wandernavi) much faster, but it is sufficient. However, only GPS and GLONASS satellites not also be located from Y330. If anyone knows if you can change that, I would appreciate a note. In buildings the GPS does not work (would have surprised me). I use the GPS alone, ie without "A-GPS" because I only have a prepaid card for Tel. / SMS in Smartphone. Also, I've been playing: Dictionary dict.cc English / French / Ital, Chess Free, Skype, a scientific calculator (RealCalc), WPS Office and Note Everything.... No games, music etc. From previously played at delivery programs I've Bitcasa, the amber side and a lot of Google stuff disabled. The apps now occupy about 400 MB. Very good, I find the "Authorization Manager" with which I specifically can prune their sometimes strange but rights-wishes individual apps. I have no idea whether all have the androids or if that's what special of Huawei. I have yet similar no jerking during program run found. For my applications so that 512 MB of RAM seems to be enough. The voice quality for telephony or Skype is normal. Youtube can I see in the domestic wireless liquid, but the power in the 4 "display is not really fun. The WLAN of Y330 works at my home very well. The maps for the navigation software (about 3 GB) were in 30 min box. The touch keyboard has naturally not too large keys, but for smaller texts in order. Not tried, because not needed by me, I have the camera, headset and data traffic over mobile. As games run with elaborate graphics does not interest me. The Y330 is not just boasts eye-catching design, but is built appropriately. Negative I feel the relatively short battery life. I have to recharge every few days, despite not too intensive use, where the mobile phone in the car for navigation is often dependent on cigarette lighter. However, this seems to be a general problem with smartphones. Nevertheless, it would be much better for me if the device would be one or two millimeters thick, and for a larger battery would be installed. The second point of criticism, but it also affects many cell phones, is the micro-USB port. At some point, I fear, it will break. Why not provide the manufacturers the phones with larger and reliable connections for charging? The third negative point, namely the then lack guidance, has now been rectified by the manufacturer. One can now at least one English. Download instructions. Since I can not hold against the Y330 the first two negative points because otherwise my needs more than met, I forgive 5 Stars. For me it's very comforting to know that I can look forward to a fall of the device considerably more relaxed than for example the user of a fruit phones. If the broken Y330 would today by my mistake, I would buy it again.
