Hi, do you know where can I download all default ringtones? Do you know where they should be stored in phone memory?
I have suspicion Clean Master deleted all ringtones.
Local/sdcard/Alarms is empty. I tried to move there some file but I can not see any option to change alarm. Same problem for sms, calls, hangouts notifications.
Thanks

Hi android developers! An idea for app. Create simple profile. Tick what are you looking for, sex or relationship... When two profiles with the same preference are in touch phone will alert you. It might work via bluetooth. When app alerts you see the person and easy to decide whether you like him/her or don't..

Im pretty sure there already are apps like that. Im sure I remember seeing some on an android site a few years back. I just don't think they took off.

iOS users seem to be confused with new update. Always say, apple is for simple people.

acc. EN60950 the one from the safety requirements
An AC high voltage test transformer is again supplied via a variac and a rectifier is used together with a filter capacitor C to limit the ripple to acceptable values. The earthing switch ES is a safety feature and closes automatically when the power is switched off to discharge the capacitor C.

Compared with other “higher voltage” DC values, the use of 400V DC is considered preferable over a higher or lower voltage for a variety of reasons:
A link voltage of approximately 400V DC already exists in many of today’s critical space equipment
AC input power supplies for IT and telecom equipment
Light ballasts and adjustable speed drives (ASDs) that are often used to power fans and pumps in the data center
The lowest power supply cost for loads in a 400V DC bus is assured by keeping the voltage to that of existing high volume components
IEC 60950-1 calls for the same standard spacing requirements for universal power supplies operating at 90-264V AC as DC power supplies operating below 420V DC
Allows the re-use of existing high-volume AC power supply designs

In addition, 400V DC
Is well within existing 600V safety limits (US NEC/NFPA 70) and others across the world
Operates over standard 600V rated wiring and busing systems which are widely deployed in buildings today
Offers a simpler, more efficient connection to renewable energy sources with variable frequency generators that natively produce DC voltage in this range such as:
Photovoltaics
Fuel cells
Wind turbines

Fix my phone!  - 
 
Hi, from my phone disappeared all pre-installed tones, like alerts for sms, hangouts, alarm.. and I am not able to modify it. I can´t see any options to choose different tone. it is just empty. I have suspicion that happed after I run CleanMaster.
Do you have any advise how to fix it?
Thanks

Major way to fix it is not to use Clean Master, it cleans way too much.

Come on man, way too easy,. As I always said, ios is for the non-tech people who dont wanna have to think. Giving ios credit, it works( end of story)

Excellent hotel and spa at the dead sea. So calm and silent place. Have you enough from crowded places, you need to stay at here. Spa is amazing, three pools a lot of sun-beds, nice garden.. You must see the sunset over the West Bank. Enjoy the Marriott at the dead sea.

The name Sheraton belongs to the top quality of hotels and I need to say it was my pleasure to stay here more then one week. Spice Bar offers as traditional food from the middle east as well the Europe food. But it is shame to miss the Lebanon kitchen! Rooms are nice, clean and big enough. The pool at 5th is amazing. I like the hotel architecture it is strange combination of modern and traditional culture. Enjoy the Sheraton H&T in Amman!

Príjemná kaviareň v tichej štvrti mesta. Personál je vždy príjemný a dochvilný. Najlepšie je sedieť za letného podvečera na terase. Capucino robíte skvelé, tá pena!

The hotel is located 5 min walk to the down town, offshore, almost on the beach. The personal is kindly - no problem to advise, deal with anything. British breakfast are tasty, and no one can say: " it was not enough". The hotel restaurant does almost the same Menu as restaurants and hotels nearby. The prices are not bad. The entire hotel covers by free wifi. The hotel´s pool is nice, still enough umbrellas and sun-beds. Must taste snakes, a club sandwich is delicious!
