I try to call someone and click on the number in the speed dial list. Suddenly, the order of the list changes, because they are now updated. The phone dials the number that is now where I had previously sat typing. Now I hope that I can cancel the call at all ...
Sometimes the phone depends on so that you can not make or write SMS. It took me ever 20 minutes to finally be able to settle an SMS. Short shutdown brings in this type of crash anything, you have to then make, so that it cools even 10-20 minutes.
In summer, the phone is very warm, even when it is not in the sun. For an outside temperature above 30 degrees, it appears to be not done. Even then, it hardly reacts.
Browse is not fun, the page layout takes a long time even with good Internet reception, many times I've stopped trying after a few minutes.
The only solution is probably to reset it to factory settings. I have now done this for the second time. The first time, the effect lasted about 2 months.
Conclusion: A mobile phone that failed in its basic functions and regularly needs to be reset. That really makes no fun. I regret the purchase.
